Drivers door key unlocking/locking problem

It looks like everything wants to go bad on my car right now. Luckily no big things though.. yet.

A little bit ago I went to unlock my door by using the key in the door and the key got stuck slightly offset from up/down and I had to use a little force to remove it.
Now the drivers door locks/unlocks fine with the button in the car and on the remote still. The problem is only when using the key in the door. It unlocked the door half the time, and made the sound of unlocking it but didn't fully unlock it the other half of trys. Nothing happened when i turned the key to the right, and the key wouldn't automatically go back to being vertical so it coul be pulled out.

Any advice?

Does #11 seem correct? Im assuming thats all I would need.. but a second opinion always helps

11 CATCH WITH KEY CODE LEFT 1 09/2000 51218244049 $83.65

Also, does anyone know how I go about having it coded for my key? Hoping I give my vin and it comes coded..

No recoding necessary. Just disassemble, and reassemble with new parts. The bottom ring in the picture is probably what broke. I just replaced mine.

That is great information AdamI. It didn't even cross my mind that I'd be able to fix mine. Is there anything else in the cylinder that could break? Or is that pretty much it? I'm definitely ready to buy that repair kit

Open the door, and you'll see a rubber oval, kind of behind the cylinder but facing the rear of the car. Pop that out, use a size 4 or 5 hex key to unscrew the bolt. Then just wiggle the lock cylinder out of the door, and get a better idea of whats rly goin on.

As you can see, that ring circled in my picture was broken into a couple pieces so I ordered the repair kit that you linked to. Thanks a bunch.

AdamI and others that have taken this apart: This might be a stupid question, but I'm pretty sure you have to take the door panel off right? Then do what you said in post #5?

Thanks!

you better pray it broke when you were already unlocked and you were attempting to lock it.

Aha I just had that happen to me and had to get a little kid across the street to go through my ski hole and turn my car on to unlock the doors... Guess I will be doing this repair soon!

I too had locked my car and then the lock broke (remote hasn't worked for ages)! Luckily my very helpful son climbed in through the boot and turned the ignition on to unlock the car. Repair kit ordered.

Wow. Lol. Imagine if you didn't have a son and you had to do the whole tunnel rat thing. When you say repair kit, you mean the part that broke? Perhaps getting the remote working as well.

Having lock problems as well, on my '03 325i.
The driver's side door lock seems reluctant to pop up when unlocking, and when that happens, all the other three doors' locks don't respond when I try to unlock them (with key AND the central locking button in the car).
Central locking issue?

edit: I did some more digging (especially through that mother of all unlocking posts: "door locks are all crazy").
My problem looks like it has more to do with the general control module, specifically the relay responsible for unlocking all doors (relay 1-B).
For anyone interested in a detailed explanation: "BMW GM5 Door Lock Relay Schematic and Explaination"
I think I've just been posting in the wrong thread... anyway, good luck to everyone with their own issues!

Does anyone can help me to find fuses for convenience options and fuse number? I did open glove box and saw the fuse box was reading but no luck.
