I recently bought a second hand 2002 reg Liana. It came with 3 keys - 2 coded keys which both only operate the ignition, the third key opens the car and has a remote locking function which doesn't work and this key doesn't work in the ignition either. I know its not a major issue, but it's inconvenient. Does anyone know if I can get one key that will do everything? As in....remote locking and ignition too? I have replaced the battery in the remote key but no joy with that.
