Features
MK718 Four-Digit Public Mode Combination Locker Lock
The MK718 is a mechanically operated four-digit combination lock designed for shared-use lockers in gyms, leisure centres, schools, workplaces and other public or commercial facilities. Public-mode operation allows each user to select a temporary code when securing the locker.
After the locker is reopened, the temporary code is released so that the next user can select a new combination. This makes the MK718 particularly suitable for lockers that are used by different people throughout the day, rather than being permanently assigned to one person.

- Management master-key facility for authorised code recovery
- All-metal lock housing
- Powder-coated finish
- No batteries, wiring or external power supply required
- Designed for compatible metal, timber, glass and plastic doors
- Two functional lock-body lengths available
- Suitable for door thicknesses from approximately 0.6mm to 20mm
How MK718 Public Mode Works
| Stage | User Action | Lock Response |
|---|---|---|
| Locker available | The compartment is open and ready for use | A new temporary combination can be selected |
| Set a code | The user selects a four-digit combination | The selected code is used to secure the locker |
| Lock the compartment | The user operates the lock after setting the code | The number wheels automatically scramble to 0000 |
| Reopen the locker | The user enters the temporary four-digit code | The compartment can be opened |
| End of use | The user removes their belongings and leaves the locker open | The temporary code is released for the next user |
Public mode is intended for short-term locker use. Where the same person requires a permanently assigned locker and a retained code, a compatible private-mode combination lock may be more appropriate.
Automatic Dial Scrambling
The MK718 automatically returns its number wheels to 0000 when the lock is operated. This helps prevent the selected combination from remaining visible after a user has locked or opened the locker.
Automatic scrambling reduces reliance on users manually turning the number wheels after use. It does not remove the need for users to keep their temporary combination private.
Master-Key Code Recovery
An authorised management master key can be used to recover the combination where a user has forgotten their temporary code. This allows facility managers to deal with locked compartments without routinely dismantling or replacing the lock.
Master keys should be controlled, recorded and issued only to authorised personnel. Store management keys securely away from the lockers.
| Access Type | Method | Typical User |
|---|---|---|
| Normal access | Temporary four-digit combination | Locker user |
| Forgotten code | Authorised master-key code recovery | Facility manager or approved staff member |
| Next user | Selects a new temporary combination | Next person using the locker |
Mechanical Operation
The MK718 operates mechanically and does not require batteries, electrical wiring, network access or software. This can simplify routine maintenance in facilities containing a large number of lockers.
The lock housing is manufactured using metal components, including zinc alloy, brass and steel, with a powder-coated external finish. Available finishes should be confirmed when ordering.
Locker-Door Compatibility
The MK718 is designed for installation through a standard 16 × 19mm mounting aperture. Functional lock-body lengths of approximately 20.5mm and 30.5mm are available to accommodate different door constructions.
Compatibility must still be checked before ordering. Locker-door thickness, aperture dimensions, handing, cam movement, strike position and the existing internal locking arrangement can vary between locker manufacturers.
| Fitting Detail | Requirement |
|---|---|
| Mounting aperture | Standard 16 × 19mm preparation |
| Door thickness | Approximately 0.6mm to 20mm, subject to configuration |
| Functional length | Approximately 20.5mm or 30.5mm |
| Door material | Compatible metal, timber, glass or plastic doors |
| Internal mechanism | Cam, latch and strike compatibility must be confirmed |
| Door handing | Confirm the required orientation and direction of operation |
When replacing an existing locker lock, provide the locker manufacturer, current lock reference, door thickness, aperture measurements and clear photographs of both sides of the door. Although the MK718 fits many locker doors, universal compatibility without modification should not be assumed.

How MK718 Public Mode Works
Public mode is intended for lockers used temporarily by different people. The user selects a four-digit combination when securing the locker. Once the lock is operated, the number dials automatically scramble back to 0-0-0-0.
| Stage | User Action | Lock Response |
|---|---|---|
| Locker available | The locker is open and ready for use | The user can select a temporary four-digit code |
| Select combination | The user enters their chosen four-digit code | The selected code becomes the temporary operating combination |
| Lock compartment | The user operates the lock | The locker is secured and the dials return to 0-0-0-0 |
| Reopen compartment | The user enters the temporary combination | The lock can be opened |
| End of use | The user removes their belongings and leaves the locker open | The locker is available for the next user |
Automatic Dial Scrambling
When the locker is locked, the MK718 automatically returns the number dials to 0-0-0-0. This prevents the selected combination from remaining displayed on the front of the lock.
Automatic scrambling also removes the need for users to turn each dial manually after operating the lock. Users should still keep their temporary combination private while the locker is occupied.
Master-Key Override and Code Retrieval
The MK718 includes a master-key override facility for authorised management use. This allows approved personnel to manage a locker where the user has forgotten the temporary combination or management access is otherwise required.
The forgotten combination can be retrieved using the appropriate management procedure. Master keys should be securely controlled and issued only to authorised personnel.
| Situation | Access Method | Authorised User |
|---|---|---|
| Normal locker access | Temporary four-digit combination | Locker user |
| Forgotten combination | Master-key override and code-retrieval procedure | Authorised management |
| Management inspection | Master-key override | Approved site personnel |
Confirm whether the required master key is included with the lock or must be ordered separately. Where several locks are being installed, also confirm the required master-key system and number of management keys.
Mechanical Operation
The MK718 operates without batteries, electrical wiring, network access or software. This makes it suitable for sites requiring a straightforward mechanical locking system across multiple lockers.
Routine management should include checking that the number dials move freely, the lock engages correctly and the master-key procedure remains available to authorised personnel.
Locker Compatibility
The MK718 is designed to fit many standard metal lockers, but compatibility should not be assumed for every locker door. Existing lock apertures, door thicknesses, cams, latches, strikes and internal locking arrangements vary between locker manufacturers.
When replacing an existing lock, provide the locker manufacturer, current lock reference, aperture measurements and clear photographs of the front and rear of the locker door. This will help determine whether the MK718 can be installed without modification.
| Compatibility Check | What to Confirm |
|---|---|
| Existing aperture | Measure the locker-door lock opening |
| Door thickness | Confirm that the lock body suits the door |
| Lock orientation | Check the required handing and direction of operation |
| Cam or latch | Confirm compatibility with the internal locking mechanism |
| Strike position | Check that the door and frame engage correctly |
| Master-key system | Confirm the required management-key arrangement |
Typical Applications
- Gym and leisure-centre lockers
- Swimming-pool changing-room lockers
- School, college and university lockers
- Workplace day-use lockers
- Hot-desking and flexible-workspace storage
- Visitor and contractor lockers
- Retail and hospitality staff lockers
