This is my new car so i dont know much about it but the central locking is a nightmare when i lock the car the passenger and the back doors remain open and the tailgate and driver door are closing, it is a w reg galaxy and everything else like the mirrors and windows etc are working. I managed to reprogramme the key fob thanks to this sites help but there still seems to be a problem with my central locking system so if anyone has an answer for me please reply i will be very grateful!
