Hi I'm new to Forum sites so i'm trying to work out how to use it. I have a problem with my BMW 318ci convertable its 02 year and this morning I have managed to get the car door open (just as it was quite iced up) but now the locking mechanism in the door has locked on and I can't shut the door. I have tried with the key, the central locking and the door lock on the inside of the car but nothing is working. When I try with the key it makes the noise like the car is unlocking and the rest of the car is but not the drivers door. I've tried WD40 and de icer but that's not working either. Can any body help please?
