Central locking that stops working has several common causes. A Cranbourne West specialist explains.

What it usually means

If the whole car won’t lock/unlock, suspect the key-fob battery first, then a fuse or the body control module. If one door won’t lock, it’s usually that door’s lock actuator or the wiring at the door hinge (a common break point). Key-fob range issues can be the fob or its battery.

One door vs all doors is the key clue.

What you should do

Try a fresh fob battery and the manual key first. If a single actuator or the wiring is the issue, it’s a contained repair.

We test the fobs, fuses, actuators and door wiring to find the fault and quote the fix.

How we find & fix it

Because the same symptom can have several causes, we use dealer-level diagnostics and a methodical check to pinpoint the real cause — rather than throwing parts at it.
