Master Lock Key Boxes for Secure Shared Access
Master Lock key boxes provide a convenient way to store spare keys and manage access to homes, offices, rental properties, commercial premises and shared facilities. The range includes wall-mounted and portable key boxes with combination or app-managed access.
A key box can reduce the need to leave spare keys in exposed locations such as beneath doormats, inside plant pots or with multiple key holders. Authorised users can retrieve the stored key using the combination, access code or compatible smartphone app provided by the selected model.
Choose the correct Master Lock key box according to the installation method, internal capacity, access-control requirements and number of users. Confirm the exact model offered on this page before ordering, as wall-mounted, portable, mechanical-combination and Bluetooth models have different features.
Master Lock Key Box Types
| Model | Installation | Access Method | Typical Requirement |
|---|---|---|---|
| 5400D | Portable, over-the-knob design | Resettable four-digit combination | Removable key storage without permanent wall fixing |
| 5401D | Permanent wall mounting | Resettable four-digit combination | Fixed key storage at a property or workplace |
| 5406EURD | Compact portable design with shackle | Resettable three-digit combination | Small keys and installations where a compact box is required |
| 5441D | Permanent wall mounting | Smartphone app or temporary and permanent codes | Managed access where user permissions and access history matter |
Model availability may vary. Use the product selector and individual specification information on this page to confirm which Master Lock key boxes are currently offered.
Portable Master Lock Key Boxes
Portable key boxes use a shackle or over-the-knob installation rather than permanent wall fixing. This allows the box to be removed or transferred when access requirements change.
The Master Lock 5400D uses a portable over-the-knob design and a resettable four-digit combination. Its metal body and covered combination dials are designed for convenient shared-key access.
The compact Master Lock 5406EURD uses a portable shackle design and a resettable three-digit combination. Its smaller internal space makes it important to check the dimensions of the intended key, ring and identification tag before ordering.
Choosing the Correct Master Lock Key Box
| Requirement | Recommended Type | Points to Check |
|---|---|---|
| Permanent access point | Wall-mounted key box | Wall construction, fixing position and door clearance |
| Removable installation | Portable shackle key box | Shackle dimensions and intended mounting point |
| Simple shared access | Mechanical combination model | Number of combination digits and code-management procedure |
| Temporary user access | App-managed or electronic model | App compatibility, batteries and access-code functions |
| Access-history requirement | Compatible Bluetooth model | App account, user management and available history records |
| Large keys or access cards | Larger-capacity key box | Usable internal height, width and depth |
Key Box Security and Code Management
Install the key box in a suitable position and avoid locations where it can be easily observed or interfered with. Follow the manufacturer’s installation instructions and use fixings appropriate to the supporting structure.
Combination codes should only be supplied to authorised users. Change the code when access permissions change, when a contractor finishes work or whenever there is reason to believe the code is no longer confidential.
For app-managed models, review authorised users and temporary codes regularly. Replace batteries in accordance with the product instructions and ensure that the nominated administrator retains access to the relevant account.
A key box supports key control but does not replace an appropriate site security assessment. Consider the value of the protected property, the installation location and the consequences of unauthorised key access.

The 5401D is a mechanical wall-mounted model with a resettable four-digit combination. It provides shared access without requiring batteries, smartphone software or a separate key for the box.

- Estate and letting agents: access to properties during agreed visits
- Offices: storage of room, entrance, cupboard or equipment keys
- Facilities management: access for approved contractors, cleaners and maintenance teams
- Shared facilities: control of keys for gates, cupboards, equipment and common areas

Installation Guidance
Follow the installation instructions supplied with the selected Master Lock key box. Wall-mounted models should be secured to a strong supporting surface using fixings appropriate to the wall construction.
Select a position that is accessible to authorised users but not immediately obvious to passers-by. Allow sufficient room to operate the combination dials, keypad or box cover.
Portable models should be fitted to a suitable door knob, handle or secure mounting point. Check that the shackle or mounting arrangement cannot interfere with the normal operation of the door.
Combination and Access-Code Management
- Provide the combination only to authorised users
- Do not use an easily guessed code such as 1234
- Change the code when an authorised user no longer requires access
- Change the code if there is reason to believe it has been disclosed
- Keep a secure record of the current administrator or responsible user
- Review temporary codes and app permissions regularly
- Remove expired users from app-managed models
- Check batteries according to the product instructions
A key box should form part of an appropriate key-control procedure. Consider the importance of the protected property and the consequences of unauthorised access before selecting an installation position.
