I just finished dealing with the 3rd time being locked outside my car! ... I don't know what is wrong with it. It just locks whenever it feels like it. Moreover, the central lock sometimes works and sometimes it does not when I lock the car from the outside. I'm just too furious with this thing. Twice of the three times I had nothing in my pockets! It was really embarrassing and time consuming.

Probably a faulty door lock.

Open each door one at a time and the interior light should tirn on + door open sign on dash.

If 1 door doesnt turn interior light on then this door lock is probably foobard.. either that or there is a broken wire on either one of the door hinges

I had this with my old sdi lol.. used to lock when going over bumps aswell lol.. it needed 2 locks in the end..

Thanks man ... Do you know where is the fuse for the central lock so I would take it off until I solve this problem.
