run the CL funtion tests, will it lock? Does the trunk mounted IR reciever flash when your back there? Does the light on the remote come on when you press and hold the button? Does central locking work via the key on both front doors?
This could be a bad ir reciever, bad remote, door latch, cl pump and on and on, you need to isolate it more finely. The basic funtion of cl should be in the owners manual, (I might be wrong) run through ever function the owners manual has and see what it wont do, that'll help narrow it down.
