The Relocker That Wouldn't Reset
A technician is servicing a mid-1990s plate-steel home safe with a mechanical combination lock and a glass-plate relocker mounted behind the door panel. The customer reports that the door "sometimes won't open even with the right combination." On inspection, the technician finds the relocker's spring-loaded plunger is partially extended and the glass plate is intact but its mounting bracket is loose, allowing the plate to shift. The dial spins freely and the fence drops normally when the wheels align. Ambient humidity is high and there is light surface rust on the boltwork. The lock has not been removed yet.
1. How should the technician sequence diagnosis and repair, and what is the risk of simply bending the bracket back and returning the safe to service?

The symptom (intermittent failure with a correct combination) plus a partially extended plunger points to a relocker that is tripping or hanging up, not a lock-wheel problem. Sequence: (1) Open the door if possible and secure it in the open position before any work. (2) Photograph and document the relocker geometry, bracket, and plunger travel. (3) Test plunger retraction and spring return through full travel; a spring that does not fully reset under load is a failure even if it looks intact. (4) Replace the relocker assembly and bracket rather than bending the existing bracket - the bracket is a designed safety component and its geometry is not adjustable in the field. (5) Verify boltwork clears the plunger through the full lock/unlock cycle and check for rust binding that could slow the boltwork into the relocker path.
Bending the bracket back and returning the safe to service is unsafe: a relocker that hangs up can either block legitimate opening or fail to fire during an attack, defeating its purpose. The customer's intermittent complaint is exactly the signature of a marginal relocker, and a field-bent bracket has unknown geometry and no reliability margin.
2. The customer asks whether the relocker can simply be removed since it is "causing the problem." How should the technician respond?

Refuse to remove or disable the relocker. It is a manufacturer-installed security feature that is part of the safe's rated protection; removing it changes the safe's security profile and may void the rating and any warranty, and it exposes the technician and employer to liability if the safe is later attacked. Explain to the customer in plain terms what the relocker does (it fires if the door is attacked, jamming the boltwork) and why a properly functioning relocker will not interfere with normal operation. Offer the correct repair - replacement of the faulty assembly - and document the conversation. If the customer insists, decline the work and note the refusal in the service record.
