Rykkers

Hello, my girlfriend has a 2003 Citroen c3, the issue is that the remote lock is not working as we thought it should. The remote ALWAYS locks all of the doors. The remote will not open the doors unless: 1. the driver door has been unlocked manually and opened - doesn't work shut 2. the car has JUST been remotely locked, after a minute or so it will not work again thanks very much for any help you can give Ryk
