Safes rarely fail without warning. They fail after weeks of small symptoms that everybody noticed and nobody acted on. Here is what to watch for, roughly in order of how urgently we would want the call.
1. The dial feels gritty, stiff or inconsistent
A mechanical combination lock should turn smoothly with even resistance the whole way round. Grittiness usually means dried lubricant or wear in the wheel pack. Inconsistency — a spot that catches at the same number every time — is more serious and often precedes a lockout.
If you find yourself dialling slightly past a number to make it open, the lock has already drifted. That gets worse, never better.
2. The handle needs force
The handle should move the boltwork with light, even pressure. If somebody has started using two hands, or a particular technique, the bolts are binding. Causes range from a settled door and worn hinges to a bent bolt or a failing drive cam.
Forcing it is how a repair becomes a drilling job. A jammed bolt on a closed safe is a very different afternoon to a jammed bolt on an open one.
3. The electronic keypad hesitates, double-beeps or resets
Electronic locks usually give plenty of notice: a delayed response, an occasional refused code, a display that dims. Most of the time this is the battery, and most of the time people change the battery and forget about it.
If it continues on fresh batteries, the problem is the keypad, the cable or the lock body. Have it looked at while the door still opens.
4. Anything has changed about the door
Rubbing, a new gap along one edge, a door that no longer sits flush, a fresh scrape mark on the frame. Doors weighing several hundred pounds settle over years, and hinges wear. Alignment is straightforward to correct early and expensive to correct late.
5. It has simply been a long time
Manufacturers typically recommend servicing a mechanical lock annually or every couple of years. In practice the majority of safes we open have never been serviced at all — and a good number of the emergency call-outs we attend are safes that were quietly overdue for a decade.
What servicing actually involves
- Cleaning and re-lubricating the lock and wheel pack
- Checking and adjusting boltwork, hinges and door alignment
- Testing the relocker and any glass plate
- Verifying the combination against the change key
- Checking mounting and anchoring is still sound
- Replacing batteries and inspecting keypad wiring on electronic locks
It takes under an hour on most units, and it is dramatically cheaper than an emergency opening — to say nothing of a day with the contents unreachable.
