sterling 1999

My fast back sterling has a nasty habit of locking all the doors by itself. My garage says they cannot fix it unless they experience it themselves. I can usually unlock by the plip thing or the door catches but it is a bit unnerving? Any ideas?

Only, possibly, some wear or something loose in the body of the key itself.

Vibration makes and breaks the key internal contacts with the result being the doors all lock.---

many thanks for your comments,sounds like getting a complete new key and attachment would be a good idea,only have one at the moment

have you tried resetting the key?? or changing the battery, my old passat use to lock and unlock the doors whille i was in it to indicate low battery level.

The plot is thickening a bit - I have discovered from the previous owner that the car has more or less always locked itself from time to time and the garage insisted on the owner buying a new set of keys as they were being locked out while servicing.
So it seems I must live with it.
I am trying to get the previous owner to find his set, failing that the local keys shop say they can supply a key either to just open the doors or to open and start the car.
Very peculiar!?
