since the heavy rain yesterday I havn't been able to use the central locking, either remotely or with the key in the door (once, I managed to lock it after closing the drivers door hard, but not since)
is this a known problem??
Putting the key in the drivers door lock won't activate the central locking at all,only using the key blip,which is obviously not working correctly.
Is the aerial on your car in the roof at the front?.If so it's possible that it's leaked into the reciever for the remote blip,and this is why it no longer works.Does the red light work on the key?.I'd remove the trim in the roof around the base of the aerial and check for moisture.If any is present,put the reciever in an airing cupboard for 24 hours and re-seal the base of the aerial.Sometimes the circuit board on the reciever will dry out and work,other times it will be damaged and need replacing.
Edit;This probably won't help as I've just read that yours is an estate like mine and won't have a roof aerial....sorry!
