I have a problem with my citroen c3 central locking. ?

Try this;
1. Sit in the car with ALL the accessories turned off (radio, lights etc.) Make sure the doors are shut.
2. Have all the remote keys with you, not on the same key ring. Turn on the ignition with the remote key and hold down the LOCK button on the remote for about 10 seconds. If you have more than one remote key, remove the one you have just done and insert the next one and turn the ignition on and do the same again, hold the lock button down for 10 seconds.
3. When you have done this to all the remotes, remove the key from the ignition and wait 1 minute. DO NOT switch anything on inside the car and DO NOT open any door, especially the drivers one.
4. After the minute is up, open and close the driver's door and try working the remote controls, they should all be now working. Any that aren't may be faulty or have a duff battery.
