Hi everyone hope someone can help, I have a 56 plate C3 with locking problems my mother-in-law bought the car from new and few months after the warranty ran out the central locking just stopped working. She took it into citroen where they did loads of tests, reprogrammed the keys and still couldnt sort it or find the problem. I've now have the car over a year and its starting to annoy me i can lock the car by getting really close to the dash from outside of the car to lock it. i have changed the batterys in both fobs and no luck. There is a aftermarket headunit in the car but the problem was there when the standard one was still in there. i've seen a few people with this problem but no outcome can someone help ? KR Adam
