Central locking / Alarm setting issues

Fob won't lock you car?

1. The lock ring around the ignition switch - less likely. This causes startign issues - will cover that soon.
2. The lock microswitches in each door. Try the drivers door first, it'll be the one that catches the most wear.

Faulty Door Lock Micro-switches How to identify!

When locking the car with the fob the alarm wouldn't set. With help from the forum I found out that the micro switches in the door locks can go faulty.

Here's how to identify which ones(s) without a trip to the stealers.

First pull fuse 15 which should be a ten amp.

Then switch the courtesy lights off using the switch in the roof console (Depressed right)

Then turn the ignition on.

The door/tailgate open light on the lower left on the console should be off. If it is dimly lit you have a problem.

Go around one door at a time and open it. When open the light should change to brightly lit. Do this individually for the doors, the bonnet, the tailgate and this glove box.

If the status of the light does NOT change when you open something then you have a problem there.

I have just finished using this method to successfully determine that my rear left passenger door had a problem.



Microswitch is not usually the issue per se. Mostly wear not operating said switch. You can usually cobble up a wedge under the switch. Else micowitches on eBay are £2-3 delivered.
