I have had to replace my driverside door lock with a secondhand one with a key to work it of course, so I know have a key for the ignition and a key for the door lock, unfortunately the new door lock when locked only locks driverside door and none of the others, how do I get the central locking to work again?, can I just swap the microchips over into the new key?

Hello Giles123
It always seems rather an omission to me but the door key doesn't operate the central locking. How yours is now is normal.
Unless you old set-up was something special, the central locking would be operated from the remote buttons on the body of the key.
If you get a brand new, genuine key body, complete with the remote PCB you could put this on your door key blade and program it to the car's central locking. Would you need to do this though? You'll still need to carry the old key for the ignition.

If at first you don't succeed, destroy all the evidence and pretend you never tried

The ignition key MUST have the little black 'Crypto' chip marked PCF7936AS if you swap things around. If its not present, the engine won't start.Giles123 wrote:can I just swap the microchips over into the new key?
The remote PCB that Missing Lincs mentions could be in either fob and will work equally well as a remote lock/unlock in either and with or without the PCF7936AS.
Yes, still 2 keys.Missing Lincs wrote:You'll still need to carry the old key for the ignition
Yes, the car seems to be almost totally reliant on remote locking.Missing Lincs wrote:It always seems rather an omission to me but the door key doesn't operate the central locking. How yours is now is normal.
