hi i've just change my battery on my key and it does not operate the central locking is there a way of re registering the key with the car :bang:

Changing the battery shouldn't affect that function. make sure the led is lighting when you press the button. If this isn't happening make sure you have the battery the right way round and if that's ok the microswitch has probably fallen off. See my guide how to fix this.

thanks for the reply the switch is OK its just the car doesn't haggle. the immobilizer bit works but the door lock doesn't.

Having the same problem
