Hey I own a 1987 Ford Laser and I got central locking put in 6months ago, i had no problems till now, the rear passenger door will not lock. All other doors are fine and that one doesnt lock. You cant lock it manually it goes down but goes up when you let go, you cant lock it with the key as the key doesnt have a key hole of the rear passenger door. I drive everywhere i go and although the car has a alarm theives will not care cause it has a nice stereo and a GPS system (all hidden in glove box) but if they wanted to break in it wont be hard! help me please all comments appreciated..
