Central locking

[dt_]

Try opening the door, and look at the lock area on the door face that fits against the car. There should be a couple of Torx screws- these hold the lock to the inside of the door. If its loose it might not be connected to its linkage properly. Also make sure that the door striker is secure and aligned properly, the one on my old 205 fell off and the door flew open (at low speed in a car park, luckily)
