Hello, I have a problem with the central locking on my 2010 c3 picasso. The problem is with the drivers door and the remote control key fob for locking and unlocking the car. The first time the problem occurred, when the car was locked from the remote control, all doors would lock except the drivers door, but if your used the key in the barrel lock to lock the car then all the doors including the drivers door would lock normally. I took the car in to the dealer at this point but when I got there the engineer could not find any sign of the fault as all the doors were locking and unlocking normally from the remote control! Now a couple about 6 weeks later the drivers door will not unlock from the remote control, the complete reverse of the above problem, but, again if I use the key in the barrel lock then the car locks/unlocks normally. In the first instance I have tried reprogramming the key fobs by putting the in the ignition and holding the 'lock' button for 10 seconds but this did not work. I have two remote controls by the way and one is obviously older than the other but the problem occurs when using either remote control. Does anybody have any idea as to what could be going on? Help and advice is much appreciated, nictu.
