Features
Ojmar LOCKR Combi Four-Digit Mechanical Locker Locks
The Ojmar LOCKR Combi, also described by Ojmar as the OMS Combi, is a four-digit mechanical combination lock for compatible locker doors. It provides keyless everyday access without batteries, wiring or electronic programming. It is suitable for new installations and replacement projects in schools, gyms, leisure centres, workplaces and changing rooms.
The lock combines user-operated numerical access with management features for shared or allocated lockers. These include an authorised master-key override, a code-finding facility, a removable management cylinder and a visible locked/unlocked indicator. The availability of a master key as a supplied accessory must be confirmed separately.
Free Mode and Assigned Mode
The same mechanical lock supports two ways of managing locker access. Select the operating mode to match how your organisation allocates lockers.
| Mode | How it is used | Typical setting |
|---|---|---|
| Free mode | Temporary use by different people, with the combination set for the relevant locker session. | Gym, pool and leisure-centre changing rooms |
| Assigned mode | Ongoing use by an allocated person, with a code retained for regular access until it is changed. | Staff, school and workplace lockers |
Four-Digit Keyless Locker Access
Users enter a four-digit code and operate the integrated handle. The mechanical mechanism offers up to 10,000 possible code combinations and does not depend on a power supply. A status indicator provides a visible indication of whether the lock is open or secured.
The lock has a robust die-cast body and a built-in handle. Unlike a battery-powered keypad lock, it does not need charging, battery changes, network access or electronic software to operate.
Master-Key Override, Code Recovery and Cylinder Replacement
Facility staff can use the master-key override for authorised access when a user's combination is unknown or access to a locker is required. The integrated code-finding function helps authorised managers recover an unknown combination using the appropriate procedure.
The management-key cylinder is removable, allowing a compatible replacement cylinder to be fitted if a master key is lost, stolen or compromised. Master-key functionality does not mean that a master key is included with every lock. Confirm the required management keys, cylinders and keying arrangements when ordering, especially for existing locker sites.
Wet-Area Suitability and Locker-Door Compatibility
Ojmar specifies the Combi for compatible lockers in wet and dry areas, including swimming-pool changing rooms and workplace facilities. The suitability of the complete installation still depends on the door, surrounding hardware, cleaning products and maintenance conditions.
Current Ojmar information describes fitting arrangements for doors approximately 1–22 mm thick, depending on the hardware supplied. Before fitting a replacement, check the door material, mounting aperture, fixings or spacers, rear clearance, latch position and frame engagement. The manufacturer describes a non-handed design suitable for left- and right-hand doors, but the selected installation arrangement must still be checked.
See the technical specification and fitting guidance below for dimensions and installation checks. A similar-looking lock should not be treated as a direct replacement without checking the existing door preparation.
Silver, White and Black Ojmar Combi Locks
Total Locker Service lists silver, white and black versions of the Ojmar Combi. Select the required finish from the product options above and confirm the supplied configuration and lead time. Colour is a finish choice, not a change to the basic mechanical operating principle.
Choosing an Ojmar Combi Replacement Lock
When replacing an existing mechanical or keyed locker lock, check the following before ordering:
- Locker manufacturer and existing lock model or reference
- Door thickness, material and mounting-hole dimensions
- Latch position, fixing arrangement and available rear clearance
- Required shared-use or assigned-use operating mode
- Door orientation and compatible installation hardware
- Silver, white or black finish
- Master keys, replacement cylinders and management-access requirements
If the existing lock is unidentified, send photographs of its front and rear, the locker-door preparation and any visible references to Total Locker Service. Include door-thickness and fixing measurements where possible.

Specification
Ojmar LOCKR Combi Technical Specification
The Ojmar LOCKR Combi, also identified in current manufacturer information as OMS Combi, is a four-digit mechanical combination lock for compatible locker doors. The measurements below refer to Ojmar's current COMBI technical datasheet. Check the selected lock and fitting components against the existing door before ordering a replacement.
Ojmar Combi Mechanical Lock Specifications

The door-thickness range depends on using the correct fixing components. The older Ojmar COMBI brochure lists 1–20 mm, while the newer manufacturer datasheet describes 1–22 mm. Match the fitting instructions to the exact lock version being supplied.
Door Thickness and Fitting Spacers
Ojmar's current fitting guidance identifies the following spacer arrangements. Spacers and master keys are listed as optional accessories; confirm what is supplied with the selected lock before installation.
| Door thickness | Manufacturer-listed spacer arrangement |
|---|---|
| 1 mm | 5 mm and 10 mm spacers |
| 2–6 mm | 10 mm spacer |
| 7–11 mm | 5 mm spacer |
| 12–22 mm | No spacer listed |
Ojmar identifies spacer references 8001.S05PN (5 mm) and 8001.S10PN (10 mm). Before fitting, also verify the mounting aperture, rear clearance and latch engagement with the locker frame. The lock should not be treated as a universal direct replacement for an existing cam or combination lock.
Ojmar Combi Colours and TLS Product References
| Finish | TLS product reference |
|---|---|
| Silver | O8001.AT1 |
| White | O8001.AT2 |
| Black | O8001.AT4 |
Select the required finish using the product selector above. The references identify the listed TLS variants, not a guarantee that every master key, cylinder or spacer is included in the package.

Ojmar LOCKR Combi Frequently Asked Questions
Is Ojmar LOCKR Combi the same as OMS Combi?
LOCKR Combi appears in earlier Ojmar product literature, while current Ojmar documentation uses OMS Combi. Confirm the supplied model and fitting arrangement when replacing an older lock.
Will an Ojmar Combi fit my existing locker door?
Compatibility depends on the existing door preparation. Check the door thickness, material, mounting aperture, rear clearance, latch position and frame engagement. Ojmar lists compatible applications including metal, phenolic, glass, HPL laminate and melamine doors. Matching the external appearance alone does not confirm a direct fit. See our replacement locker lock identification guidance if the existing mechanism is unknown.
What locker-door thickness does the Ojmar Combi support?
The current manufacturer datasheet gives a fitting range of 1–22 mm with the appropriate hardware. Older COMBI literature gives 1–20 mm, so check which fitting instructions apply to the supplied version, particularly when replacing an older lock.
Do I need spacers to install the Ojmar Combi?
The required spacer arrangement depends on the door thickness. Ojmar specifies 5 mm and 10 mm spacer options, with the fitting combinations shown in the table above. Spacers are identified as optional accessories, so confirm which parts are included before ordering or fitting the lock.
Can the same Ojmar Combi lock fit left- and right-hand doors?
Yes. Ojmar describes the current COMBI as non-handed and suitable for compatible left- or right-hand doors. Confirm that the latch and existing locker-frame arrangement are suitable before installation.
What is the difference between free mode and assigned mode?
Free mode is intended for temporary users who choose a combination for their locker session. Assigned, or fixed, mode retains a code for repeated use by an allocated locker user. The correct mode depends on how the site manages locker allocation. For a broader comparison, see our mechanical locker combination locks guide.
Is a master key supplied with every Ojmar LOCKR Combi?
The lock supports authorised master-key override, but Ojmar lists the master key as an optional accessory. Check whether the required management key is included in the selected order or needs to be purchased separately, particularly for a multi-lock installation.
Can staff recover a forgotten Ojmar Combi combination?
Yes. The COMBI provides a code-finding function for authorised site management. Recovery requires the appropriate management access and must follow Ojmar's operating instructions. Staff should control the master keys and code-recovery procedure.
Can the management cylinder be replaced separately?
The COMBI has an interchangeable management cylinder. A compatible replacement can be fitted if a master key is lost or compromised, without automatically replacing the complete lock. Confirm the cylinder and management-key arrangement before ordering parts.
Is the Ojmar Combi suitable for wet changing rooms?
Ojmar specifies the COMBI for compatible wet- and dry-area installations. Suitability also depends on the locker door, surrounding fixings, cleaning regime and conditions at the site. Check the complete installation before ordering.
