Central Locking Not Working: Causes
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.
