This guide explains how to replace locker locks in the UK, including identifying your existing lock, checking compatibility, choosing the correct replacement and deciding when to upgrade instead of like-for-like replacement.

For technical fit, use our locker lock compatibility guide UK. For system decisions, see mechanical vs electronic locker locks.

When should you replace locker locks?

• Lost or missing keys: especially across multiple lockers
• Locks not working: stiff, jammed or unreliable
• Damage or vandalism: forced or broken locks
• Obsolete locks: no longer supported or inconsistent
• Changing usage: moving to shared or flexible lockers
• Security upgrade: improving access control

If problems are isolated, replace individual locks. If issues are repeated across the site, consider a full replacement or upgrade strategy.

Step-by-step: how to replace a locker lock

• 1. Identify the lock type: cam lock, coin lock, combination or electronic
• 2. Measure the lock: diameter, door thickness and cam length
• 3. Check fixing type: threaded nut, clip or screw fixing
• 4. Remove the old lock: undo fixing and remove cam
• 5. Insert the new lock: fit from the front of the door
• 6. Fit the correct cam: match length and orientation
• 7. Secure and test: tighten and check smooth operation

Always test locking, alignment and door closure before returning the locker to use.

See locker lock cost UK guide for full breakdown.

Common replacement mistakes

• Not measuring lock diameter
• Ignoring cam compatibility
• Choosing incorrect fixing method
