Thanks for the reply.The c/locking is not remote, it's from the key. It's now moved on to only being able to lock the driver's door with the key, all other doors remain unlocked, so I have had to lock the doors using the switch on the armrest as I get out. Also, the driver'sdoor catch itself has started to 'stick' so that sometimes, without warning,it will not close so the car cannot be driven. That has happened about six times. Yesterday I was on my way home to South Wales from Cambridge with my 5 yr old grandson as passenger. We stopped at a services just outside Birmingham, went in for a break, but when we got back to the car, the driver's door wouldnt shut. I tried releasing it, as I had managed to do previously, but after getting soaking wet and filthy from the oil on the catch, had to phone the AA. While waiting for assistance, I tried the door again and it shut!! It's going into a garage tomorrow cos I cant trust it not to do it again, and I drive a lot in my job, so can't be doing with having to mess around. It's put me right off the car, and I'd only just started to get used to it!
Will let you know what the garage say.
