MAX portable combination key safes give site managers, contractors, and facilities teams a simple, secure solution for shared key access. The resettable 4-digit code provides 10,000 possible combinations. The removable top shackle attaches to scaffold, site fencing, or railings. The rear fixing holes allow permanent wall mounting on welfare units, site offices, or gate posts. A protective weather cover keeps the combination dials clean and functional in outdoor conditions.
How a portable key safe removes the operational problems of shared site key access
Shared key access on construction sites creates a recurring problem. Keys passed between operatives get lost. Operatives arriving out of hours cannot access the site if the keyholder is unavailable. Courier-style deliveries of keys across multiple sites cost time and create a chain of custody risk. A combination key safe stores the key on site, accessible only to those who know the code. The code can be reset between operatives, contractors, or access phases. No physical key to pass. No keyholder required.

Who is this for
This key safe suits site managers, facilities managers, and contractors who need to manage shared access to a site, building, or compound without relying on a physical keyholder being present. It is particularly suited to construction site compound gates where multiple trades require access across different shift hours, facilities and property managers providing out-of-hours access to maintenance contractors, and project managers coordinating access across sites where courier key delivery is impractical.
Typical applications
-
Site compound and gate key storage allowing authorised operatives to access the site outside normal management hours.
-
Shared access management for construction sites where multiple sub-contractors and trades require gate key access across different shift patterns.
-
Welfare unit and site office access control during construction phases where the site manager is not always on site.
-
Out-of-hours access for maintenance and M&E contractors attending facilities without a permanent keyholder on site.
-
Plant and equipment compound access where machinery keys need to be accessible to authorised operatives without a physical handover.
-
Emergency access key storage at building entrances for fire, maintenance, or security response teams.
-
Temporary property access management during refurbishment and fit-out projects.
How to use
Setting the combination for the first time:
Step 1: The default combination is 0000. Use this to open the key safe on first use.
Step 2: To reset the combination, open the safe and locate the reset button inside.
Step 3: Press and hold the reset button, set your new 4-digit combination on the dials, then release the reset button. Your new code is now set.
Step 4: Close the safe and test the new code before storing keys inside.
Daily use:
Step 5: Align the dials to the correct combination. Press the release button to open the safe and retrieve or return the key.
Step 6: Scramble the dials after closing to prevent the code being read.
Attachment:
Step 7: To attach via shackle, locate the shackle through a scaffold tube, fence rail, or chain link and lock it into the top of the safe body.
Step 8: To wall mount, remove the shackle, position the rear of the safe against the wall, and fix through the rear holes with appropriate fixings.
Common mistakes
- Not scrambling the dials after closing. Leaving the dials set at the correct code allows anyone to open the safe without knowing the combination.
- Storing multiple keys without confirming they all fit. Check the internal dimensions accommodate the number of keys required before relying on the safe on site.
- Not resetting the code when access permissions change. The code should be reset whenever a contractor, operative, or phase access period ends.
- Mounting in a position where the combination dials face directly upward. Water can pool in the dial mechanism. Mount with the face vertical or angled downward where possible.
Security note
This key safe provides convenient shared access management for site and facilities use. It is not certified to Sold Secure or insurance-grade security standards. For applications where an insurer requires a rated key safe, confirm the security grade required before ordering.
