Central Locking Failure

Malookoo · 9th May 2024, 20:11

Today suddenly on my 75 Tourer the central locking stopped working completely won’t lock or unlock anything not from the fob or the switch near hand break, the fob still operate the alarm/immobilizer.
Anybody any idea what might take it down like that? Would be grateful for any help.

Have you checked your fuses?

Yesterday the central locking on my 75 tourer stopped working completely, won’t lock or unlock anything from the key fob or the switch near the handbrake. Had no problems with it before now suddenly nothing. Immobiliser/alarm still working a manual locking is OK

Anybody got any idea what might have caused this

Key fob battery failing ? - do you have a 2nd key to test.

Would that cause an inoperative centre button?
Is the led on your key fob illuminating? If yes
Check fuses first.
Cabin fusebox according to Haynes.
F1 20AMP BCU
F5 5AMP BCU
F24 30 AMP BCU

Key in the door lock will deactivate the alarm ECT.

Hi not checked fuses yet, but must confess it was my thought as every thing was fine then suddenly nothing locking or unlocking. But alarm/immo working on key fob

Hello Phil,

If neither the centre console switch (central locking) or the key fob buttons (superlocking) work then we can discount the key fob battery.

The master switch on the centre console is wired directly to the BCU. Do you have any other body related faults?
