ZKTeco ML300 Bluetooth Fingerprint Lock in Dubai, UAE
The ML300 is a Bluetooth 5.0 fingerprint and keypad smart lock for compatible residential, apartment, rental and light commercial doors where users need convenient keyless entry and flexible visitor access.
It combines smartphone, fingerprint and passcode identification with an optional gateway for remote functions. FourTeck helps buyers check the door, mortise, backset, quantity and remote-management requirement before a quotation is prepared.
Fingerprint + Passcode
Gateway Optional
A Practical Smart Lock for Controlled Everyday Access
The ZKTeco ML300 is designed for buyers who want to move away from managing physical keys without building a complex enterprise access-control system around a single door. It places fingerprint authentication, passcode entry and smartphone access into one compact lock platform. That makes it relevant to private apartments, managed residential units, short-term rentals, staff rooms, small offices and other compatible doors where the owner needs a simple way to add or remove authorized users.
The most important buying point is door compatibility. A smart lock is not selected only by its access features. The physical door thickness, existing hole arrangement, mortise or latch type, backset and opening direction must also match. ZKTeco specifies a standard door thickness of 30 to 60 mm, an adjustable 60 or 70 mm backset for the American-standard single latch, and an optional German-standard mortise. The reversible design helps with different opening directions, but the exact door should still be checked before ordering. A buyer replacing an existing lever or knob on a suitable single-hole door may benefit from the model’s no-drilling approach, while unusual doors can require a different lock family.
For day-to-day entry, the lock can identify users by smartphone, fingerprint or passcode. The capacitive fingerprint sensor is useful for frequent authorized users because it removes the need to remember a code. Passcodes are useful for people who should not be enrolled biometrically, and temporary or dynamic code functions can help with guest access scenarios. Bluetooth is the local communication method. Buyers who need remote unlocking, remote log viewing or remote code sharing should plan for the additional Bluetooth gateway rather than assuming the base lock provides internet connectivity by itself.
For Dubai and UAE procurement, FourTeck can help translate these product details into a practical order. Share the door type, thickness, latch or mortise requirement, number of locks, preferred access methods and whether remote control is needed. FourTeck can then assist with model confirmation, quotation, delivery coordination and related installation or warranty guidance. This approach is especially useful for property managers and businesses ordering several units because a small compatibility mistake can become expensive when repeated across multiple doors.
Why the ML300 Can Simplify Door Access
Its value comes from combining several practical access methods with manageable installation requirements. The benefit is not simply “smart entry”; it is the ability to choose the right credential for permanent users, visitors and property operators while keeping the door experience familiar.
Give Different Users Different Ways to Enter
Employees, family members, residents, cleaners and short-term guests do not always need the same credential. Fingerprint access suits frequent authorized users, passcodes can be assigned without carrying a key, and smartphone management supports a more convenient administrative workflow. This mix helps reduce reliance on one access method and can make user changes easier when a person no longer needs entry.
Bluetooth Without Mandatory Door Cabling
Bluetooth 5.0 gives the lock a local mobile connection without requiring a network cable to the door. For a single apartment or a small group of compatible doors, that can simplify deployment compared with a wired access-control architecture. Buyers should still plan mobile administration and gateway needs carefully.
Designed for Suitable Existing Single-Hole Doors
The no-drilling design can reduce alteration work where the existing door and latch arrangement match the supported installation. This matters for managed properties where owners prefer a cleaner retrofit. Physical dimensions and mortise choice should be confirmed before purchase rather than assumed from photographs.
Temporary Access Helps Reduce Key Handover Friction
Properties with cleaners, maintenance teams, rotating guests or contractors often need time-limited access rather than permanent credentials. ZKTeco lists temporary access and random passcode capabilities for the ML300. When the optional gateway and compatible app workflow are used, managers can support remote functions such as sharing temporary or dynamic passcodes. The exact remote workflow should be planned around the gateway, mobile app and operating environment.
Battery Operation Keeps the Door Installation Simple
The lock uses four AA alkaline batteries and includes a Micro-USB backup power interface. ZKTeco states battery life of up to 1.5 years or about 10,000 accesses under its stated conditions. Actual life will vary with use, battery quality and environment, so planned battery replacement remains important.
Capacity Suits Small Controlled User Groups
A capacity of up to 100 users, fingerprints and passcodes makes the ML300 more suitable for a home, rental unit, small office or limited-access room than for a large enterprise with thousands of identities. Matching the lock to the actual user count helps avoid overbuying or choosing a device that is too small.
The Details That Matter Most Before You Buy
The ML300 is strongest when a buyer needs biometric access in a straightforward retrofit-style lock rather than a fully networked commercial controller. Its Bluetooth connection, capacitive fingerprint sensor and keypad support everyday access needs without forcing every user to carry a separate card or physical key.
The optional gateway is a major decision point. Local Bluetooth management and remote internet-based management are not the same thing. If a property manager expects to unlock a door from another location, review records remotely or share remote access through the ZSmart ecosystem, the gateway should be included in the requirement. If only local fingerprint and passcode entry are needed, the buying scope may be simpler.
Voice control is listed for compatible Amazon Alexa and Google Assistant environments. Buyers should treat this as an optional smart-home integration feature rather than the primary access method. In business or managed-property scenarios, the priority should remain credential policy, door compatibility, who administers users, battery maintenance and what happens when a guest or staff member needs access outside normal hours.

How to interpret these specifications
A lock can meet the electronic requirement and still be wrong for the door. Start with the physical fit: thickness, existing latch or mortise, backset and opening direction. Then decide how people will be enrolled and managed. If the site needs only local fingerprint and passcode use, the base deployment can be simpler. If a property manager must act remotely, the optional gateway becomes part of the project.
For multi-door orders, do not assume every door is identical. Measure representative doors and identify any exceptions, especially in renovated apartments, older offices or mixed-property portfolios. Also confirm who will maintain batteries and administrator access. These operational details have a larger effect on a successful deployment than selecting a lock from its appearance alone.
Confirm the Door Before Confirming the Order
The highest-risk buying decision is physical compatibility, not the fingerprint feature. A short door checklist before quotation can prevent a lock that looks correct on paper from becoming difficult to install on site.
What door are you fitting?
Measure the door thickness and identify whether the current hardware uses a compatible single latch or requires the optional mortise. Photographing the door edge, existing latch and handle area can make a quotation review more useful.
How many users need access?
The published capacity is 100 users. A private apartment or small office may be comfortably within that range. A large organization with hundreds of staff, centralized identity control or detailed reporting requirements may need a different access-control architecture.
Do you need remote access?
Remote control is not simply a Bluetooth feature. ZKTeco specifies that a Bluetooth gateway is required. Include it when managers need remote unlocking, remote log review or remote temporary-code workflows through the supported app environment.
Who will administer credentials?
Decide who can enroll fingerprints, create passcodes and remove former users. A managed property needs a clear process so departing tenants, contractors or employees do not keep unnecessary access.
What is the power-maintenance plan?
The lock runs on four AA alkaline batteries. Assign battery inspection and replacement responsibility, particularly in rentals or business locations where no single resident is responsible for maintenance.
What should you send FourTeck?
Provide model reference, quantity, door thickness, lock photos, opening direction, mortise or latch information, delivery location, remote-access requirement and target date. For multiple properties, identify whether all doors are the same type.
Where This Lock Fits Best
The ML300 fits situations where one door or a small group of doors needs convenient identity-based entry without the complexity of a full enterprise access-control panel. The right use case depends on user count, administration method and physical door compatibility.
Managed Apartments and Rental Units
A rental property often needs access for residents, cleaners, maintenance teams and occasional guests. Physical key duplication can become difficult to track, especially when occupants change. Fingerprint access can suit permanent users, while passcode and temporary-access functions can support visitors or service providers. Where remote management is required, the optional gateway should be included. Property managers should standardize battery checks and credential removal so each tenancy handover includes an access reset process.
This use case works best when the doors use a compatible latch or mortise and the user population is well within the lock’s stated capacity. It is not a replacement for a centralized high-security building access platform where every event must be managed across hundreds of doors.
Small Offices and Staff Rooms
A small office may need to control a manager room, records room, stock room or staff-only area without installing a complete controller. Fingerprints can give frequent users quick access, while passcodes offer an alternative for approved visitors. The 100-user capacity should be compared with current and expected staff numbers before purchase.
Private Homes and Villas
Home users may value the ability to unlock by fingerprint or code without carrying keys. Smart alerts, random passcode features and optional voice ecosystem support add convenience. The main buying task remains door fit: exterior exposure, door type and existing hardware must be suitable for the published operating and installation conditions.
Serviced Accommodation
Serviced units benefit from access methods that can change between guests without redistributing keys. Temporary or dynamic passcodes can support this workflow, especially when paired with the required remote gateway. Operators should establish a repeatable process for code validity, battery checks and emergency entry.
Low-Complexity Controlled Rooms
For a small room that does not require card readers, electric strikes, door controllers or enterprise software, a standalone smart lock can be easier to operate. Buyers should not use this as a substitute where compliance, multi-door central management, emergency-release integration or high-assurance audit requirements call for a dedicated access-control system.
ZKTeco ML300 Fingerprint, Passcode and Smartphone Access
A mixed-access lock is useful because one credential method rarely suits every person. Fingerprints are convenient for regular users who want fast entry without remembering a code. Passcodes are practical when a visitor, contractor or temporary resident should not be enrolled biometrically. Smartphone access gives the administrator another way to interact with the lock and supports the broader ZSmart management workflow.
The buyer should define the access policy before deployment. For example, a property manager can decide that residents use fingerprints, maintenance teams receive temporary codes, and the administrator uses the mobile app for management. That is safer operationally than enrolling everyone in the same way and then forgetting which credentials are still active.
The stated capacity of 100 users is generous for a single apartment or small office, but capacity alone does not determine suitability. If a business needs centralized identity synchronization across many doors, detailed enterprise reports, integration with HR or a formal access-control server, a standalone residential-style lock may not be the correct architecture. FourTeck can help distinguish between a smart lock requirement and a broader access-control project.
ZKTeco ML300 Bluetooth 5.0 and Remote Gateway Planning
Bluetooth 5.0 is the lock’s published communication method, but buyers should separate local Bluetooth control from remote internet-based access. ZKTeco states that remote access requires an additional Bluetooth gateway. This single distinction can change the bill of materials, installation position and day-to-day management workflow.
For a single home, the administrator may prefer local use and avoid extra gateway hardware. For a rental operator managing units from another location, remote functionality can be central to the reason for buying the lock. In that case, gateway coverage and the supported app setup should be considered from the beginning instead of added only after installation.
Voice control is another dependency-based feature. The manufacturer lists compatibility with Amazon Alexa and Google Assistant when properly paired. Organizations should evaluate whether voice unlocking aligns with their security policy before enabling it. Convenience features should support a defined access process, not replace one.
ZKTeco ML300 Door Fit, Battery Power and Daily Maintenance
A smart lock is a mechanical product as much as an electronic one. The most reliable purchase starts with dimensions and door hardware. ZKTeco lists standard support for doors 30 to 60 mm thick. For the American-standard single latch, the published backset is adjustable to 60 or 70 mm, while a German-standard mortise is listed as an optional configuration. These details should be checked against the actual door before the lock is ordered.
Battery operation reduces the need for fixed power wiring to the door. The ML300 uses four AA alkaline batteries, which the manufacturer states are not included. The published battery-life figure is up to 1.5 years or approximately 10,000 accesses. That should be treated as a planning reference rather than a guarantee because traffic, battery quality, temperature and usage patterns affect real life. A maintenance process matters more than the maximum number on a datasheet.
Record door thickness, latch type, backset and opening direction. Check frame clearance and decorative trim that may obstruct the front or rear assembly.
Assign responsibility for battery replacement and user administration. In rentals, include these tasks in the property turnover checklist rather than waiting for access problems.
Know how backup power through the Micro-USB interface is used and keep an appropriate plan for emergency access. Do not depend on one credential or one person knowing the administration process.
For larger projects, installation consistency matters. If a building has different door vintages, sample more than one door before ordering the full quantity. A site can appear standardized while hiding different latch depths, frame clearances or replacement history. FourTeck can use the measurements and photos supplied by the buyer to help prepare a more accurate quotation and identify where an alternative ZKTeco smart-lock model may be more appropriate.
What Buyers Should Check Before Purchase
The biggest mistake is choosing a smart lock only from its fingerprint and app features. The correct order must match the physical door, expected user count, remote-access workflow, administrator responsibilities and ongoing battery maintenance.
Configuration Fit
Confirm thickness, backset, latch or mortise type, door direction and handle clearance. The 30–60 mm thickness range is only one part of fit. Send clear door photos and dimensions when the existing hardware is uncertain.
Compatibility Check
If remote management is required, include the supported Bluetooth gateway and confirm the local network environment. If the requirement includes centralized enterprise access, attendance or multi-door reporting, review whether a standalone smart lock is the right architecture.
Availability and Warranty
Ask for the exact finish, mortise option, package contents and gateway requirement on the quotation. FourTeck can provide current availability and warranty guidance based on the quoted supply channel; these details can vary by supplier and order quantity.
Quote Preparation
Send the required quantity, delivery location, door details, access methods, gateway requirement, target installation date and whether installation support is needed. For projects, separate identical doors from exceptions so pricing and fit can be reviewed more accurately.
Is this model suitable for a business office?
Yes, it can be suitable for a small office, private room or limited-access door when the 100-user capacity, standalone management style and physical installation meet the requirement. It is less suitable when the organization needs centralized enterprise identity, integration with a large access-control platform, multiple supervised doors or advanced compliance reporting.
What configuration do I need for remote rental management?
Plan the ML300 together with the required Bluetooth gateway and the supported ZSmart app environment. Confirm the site’s network coverage and who will administer temporary or dynamic passcodes. A property with several units should also have a repeatable process for naming locks, changing access between guests and replacing batteries.
What should I check before replacing an existing handle?
Measure the door thickness and backset, identify the latch or mortise, confirm the door opening direction, and check whether surrounding trim leaves enough clearance. A compatible single-hole door can support the intended no-drilling retrofit approach, but non-standard doors may require another model or installation plan.
Buying Support for Dubai and UAE Requirements
FourTeck supports inquiries for ZKTeco smart-lock requirements across Dubai and the UAE with model review, quotation assistance, configuration checks, delivery coordination and warranty guidance. Availability can vary with supplier status, finish, mortise option, gateway requirement and order quantity, so the current quotation should be used as the commercial reference rather than assumptions about stock.
Selection support
Share the door type, user count and preferred access method. FourTeck can help determine whether this smart lock or another access-control product better matches the requirement.
Delivery coordination
Project quantities and delivery timing should be confirmed during quotation. For multiple sites, provide each delivery location and target date so the supply plan can be reviewed.
Warranty guidance
Warranty terms can depend on the supplied channel and quoted item. Ask FourTeck to state the applicable warranty handling and any installation conditions on the quotation.
Dubai, Abu Dhabi, Sharjah and Ajman Coverage
Businesses, property managers and residential buyers in Dubai, Abu Dhabi, Sharjah, Ajman and other UAE locations can contact FourTeck for current product availability, compatibility review and quotation support. The practical information to provide is the same regardless of emirate: quantity, delivery location, door construction, thickness, latch or mortise type, remote-access requirement and intended user group.
For multi-site projects, identify whether the doors are standardized. A portfolio of apartments or offices may contain different door hardware even when the buildings appear similar. FourTeck can help review the requirement as a project instead of treating every unit as identical, which can reduce last-minute changes to lock, latch or gateway scope.
GCC and Africa Availability
FourTeck also supports business technology inquiries across selected GCC and Africa markets through regional platforms and inquiry channels. Buyers in Saudi Arabia, Qatar, Oman, Kuwait, Bahrain, Kenya, Uganda and other Africa-region locations can discuss smart-lock, access-control and related physical-security requirements. Product availability, delivery methods, warranty handling and installation options can vary by country, supplier status and project quantity.
For regional projects, provide the number of doors by country, expected installation environment, preferred model, required timeline and whether the same hardware standard is used at every site. This is especially important when local door formats differ. FourTeck’s regional channels can help buyers organize requirements before commercial confirmation.
Other ZKTeco Smart-Lock Options Buyers May Consider
A different ZKTeco model may be more appropriate when door construction, connectivity or the type of property changes. The related models below should be treated as comparison starting points, with final specifications confirmed for the selected model and region.
ZKTeco ML200
A related smart-lock model in the ML family that can be considered when the buyer wants to compare installation format and supported access functions. Confirm current specifications and door compatibility before substituting it for the ML300.
ZKTeco ML100
A smart mini lever-lock option worth reviewing where a buyer needs a compact form factor. Door type, mortise requirement, connectivity and capacity should be checked against the exact project rather than assumed from the family name.
ZKTeco GL300W
Designed around glass-door requirements rather than a standard wooden-door retrofit. Consider it when the installation surface itself makes the ML300 unsuitable.
ZKTeco TL300B
Another Bluetooth-enabled fingerprint lock family to evaluate when handle style, lock format or required features differ. Request the current datasheet for exact comparison.
Enterprise Access Control
If the project needs centralized users, many doors, audit reporting, card readers or integration, a dedicated access-control system may fit better than a standalone smart lock.
FourTeck UAE Technology Support
For projects that also include CCTV, networking or other IT equipment, requirements can be coordinated through FourTeck’s broader technology services.
Practical Help Before the Lock Reaches the Door
A lock purchase becomes easier when the technical and commercial questions are answered together. FourTeck’s role is to help buyers define what they actually need, prepare a quotation around that requirement and coordinate the next steps without relying on unsupported stock, delivery or warranty promises.
Review whether a standalone Bluetooth smart lock fits the use case or whether a centralized access-control system would be more appropriate.
Discuss door thickness, latch or mortise type, backset, opening direction and physical fit before ordering multiple units.
Build the request around quantity, gateway requirement, delivery location and project timing so the quotation addresses the real scope.
Coordinate delivery requirements across UAE sites based on confirmed supplier status and project quantities.
Clarify the warranty terms that apply to the quoted supply instead of assuming coverage from unrelated marketplace listings.
For larger security projects, compare smart locks with readers, controllers, CCTV and network requirements so each door uses the right class of product.
ZKTeco ML300 Buyer Questions
These answers focus on practical selection, installation and purchasing considerations for buyers evaluating the ML300.
What is the ZKTeco ML300 used for?
It is a Bluetooth-enabled fingerprint and keypad smart lock for compatible doors where users need keyless access by smartphone, fingerprint or passcode. ZKTeco positions it for private houses, apartments and short-term rental scenarios. It can also suit selected small-office or controlled-room doors when the user capacity, door fit and standalone management style match the requirement.
Does the ML300 support remote unlocking?
Yes, remote access is supported when the additional Bluetooth gateway is used in the supported ZSmart environment. The base lock communicates through Bluetooth 5.0, so buyers should not assume that the lock alone connects directly to the internet. Include the gateway requirement in the quotation if remote unlocking, remote records or remote temporary-code workflows are needed.
How many fingerprints and users can it store?
ZKTeco lists a user capacity of 100, a fingerprint capacity of 100 and a passcode capacity of 100. That is generally appropriate for a household, managed unit or small controlled user group. If the site has a much larger population or needs centralized management across many doors, FourTeck can help review a different access-control approach.
What door thickness does the lock support?
The published standard door-thickness range is 30 to 60 mm. Buyers should also check latch or mortise type, backset, opening direction and clearance around the handle area. For the American-standard single latch, ZKTeco lists an adjustable 60 or 70 mm backset. Door measurement is recommended before ordering, particularly for project quantities.
What batteries does the ML300 use?
It uses four AA alkaline batteries, which ZKTeco states are not included. The manufacturer lists battery life of up to 1.5 years or about 10,000 accesses under its test conditions. Real battery life can vary with traffic, battery quality and environment, so businesses and rental operators should establish a routine battery replacement plan.
Can FourTeck help confirm compatibility before I buy?
Yes. For a useful review, share the door thickness, latch or mortise information, opening direction, photos of the existing lock area, required quantity and whether remote access is needed. FourTeck can use these details to help assess whether the ML300 appears suitable and whether additional items such as the Bluetooth gateway should be included in the quotation.
Is the ZKTeco ML300 available in Dubai and the UAE?
FourTeck can support Dubai and UAE inquiries for this model and related smart-lock products. Current availability should be confirmed at the time of quotation because supplier status, finish, mortise option, gateway requirement and order quantity can change. Contact FourTeck with the exact requirement rather than relying on an older online stock indication.
Can businesses request multiple units?
Yes, businesses and property managers can request project quantities. For larger orders, first confirm whether all doors share the same thickness, latch or mortise and opening configuration. Sending a door schedule or sample measurements helps reduce the risk of ordering the same lock setup for physically different doors. FourTeck can then prepare quantity-based quotation and delivery guidance.
When should I choose a full access-control system instead?
Choose a broader access-control platform when the project needs centralized identity management, many supervised doors, card readers, controller integration, detailed audit reporting, HR or attendance integration, emergency-release logic or site-wide security policy. The ML300 is better aligned with standalone smart-lock use where convenience and local door control are the main priorities.
Need Help Choosing the Right Smart-Lock Setup?
FourTeck can review the door type, required quantity, access methods, gateway requirement, delivery location and installation expectations before preparing a quote. This helps avoid ordering a lock that has the right electronic features but the wrong physical fit.
Share the model, quantity, door thickness, latch or mortise details, opening direction, remote-access need, delivery location and target date.
