Trouble with central locking

I have a 1991 318i 4 door. Yesterday when I went to lock it on the driver's door, it wouldn't turn. After fiddling with it, it finally turned over and locked the doors however it wouldnt allow the key to turn back vertically to take it out. The cylinder would stay horizontal not allowing me to either unlock from the drivers door or the trunk or pasenger door. I eventually got the cylinder upright but cannot unlock now fromt eh drivers side. Has anyone had any problems like this before and if so, how did you fix it? I am not new to cars or mechanical work at all, however I am new to BMW's. Any help is appreciated.

Jon, sounds like your door lock cylinder needs rebuilding. They can seize and seeing you were able to put it into dead bolt (horizontal) and trouble returning it back gives me that indication. You can take your old one out and take it apart - possibly freeing it up by cleaning it or you can buy a lock cylinder kit from the dealership which will allow to rebuild it. Or you buy a used one and you'll have to take it apart and recode it. I do have a good used lock cylinder. But honestly, your best bet is to buy it new. Drivers side is used the most and therefore wears out the quickest. Not an uncommon occurrence.

good luck

Would anybody be interested in rebuilding these for me? Of course, I would pay someone to do it. You said it takes about an hour to rebuild each cylinder in your thread so $100 for whoever does them and I will provide the parts!?! I am in Hamilton.
