Replacing a door lock cylinder

Hi all,

I've scrolled and scrolled through everything I possibly could but cannot find a good diy for replacing the door lock cylinder for my 318 ci, its 2001. The key is turning both sides with no friction and no door lock working. Make things worse is that my key fob has just died on me too so my car is sitting idol with all doors open!!! Please help, need it asap!!!

I will be replacing mine tonight if you haven't gotten this issue figured out yet...look for a diy on removing the door card first and I will try to post some pics on everything after that as I have already removed my door card.

Small DIY for the lock cylinder

OK, well, once you remove the door card, you will see a rubber type cover which is held in by a plastic clip. You will see it on the bottom right corner of the plastic cover shown in the image below.

Make sure you pry it out gently without breaking the clip, but, with enough force to pop it out.

You will then need an allen key, not sure what size, i can't remember off the top of my head to loosen the allen key screw and remove...it's a two stage screw where you can loosen it, pull it out a little, and then you can unscrew it the rest of the way and take it out. Be careful not to drop it in the door otherwise you will be fishing with your fingers trying to get it out.

A picture of the allen key screw and it's location is below...

Next, hold the door open, pull on the door handle, and wiggle out your lock and lock cylinder...your lock cylinder itself is probably fine, but, all the guts holding it together from behind has broken apart.

Once it's out you can take off the plastic cover that is on the lock cylinder...

Now you can put the black cover on your new lock cylinder, and put it all back together.

Any questions, let me know...Cheers and Good Luck

Your DIY was confusing, lacking a clear description

of where you were and what parts you were working with.
But my biggest gripe is that you caused me to go blind with those blurry pics. So now I'm not worrying any longer as I cannot drive if I cannot see.

Thanks and Oiling the lock shaft worked well for me

I just wanted to register and say thanks for all the info on this page. I just replaced the door key cylinder on my 2003 325xi. Took a lot less time because of this page. Something that also worked for me though was oiling the lock shaft that goes down the door card (aka door panel) That is, when I replaced the whole cylinder from the hex screw on the side of the door, the inside was so rusted that it only turned part of the way, (my car might have some water-seal problems) and would not unlock. So if you are 100% sure you have installed it properly and the key still won't turn it all the way, try some old motor oil down the lock shaft (the little black button that moves up and down when you unlock the door) and give it a good 15-20 minutes to let the oil work in. I was ready to give up after I oiled it, but then I came back and it worked like a champ. Message me if this isn't clear. Good luck!

I am going to have to replace my lock too, one question is can you use the original key. I too have broke the key fob and use the good old fashioned key in the door trick to get in. Trouble is I am at my holiday home in Spain and BMW here charge a fortune, was thinking about tackerling the job myself but can not get an answer about the key. So now my car is unlocked all the time.

Door lock cylinder was easy to remove - just lift up the rubber flap piece on the end of the door and use an allen wrench to remove the screw. (I didn't remove the little plastic clip holding the flap, I just gently pulled the corner over the clip and then stretch it back over when I was done.) Then, just wiggle the key lock straight out.

My Ride: BMW 323 CI Cabrio
Wanted to post a thank you for the info in this thread. Had a couple of dirtbags try to steal my wifes 323 ci convertible last week by pulling the drivers cylinder with a slide hammer and looking for the valet key. My buddy interupted the guy and he jumped into a stolen nissan maxima. Clean job on the cylinder with no damage to any other part of the car. Dealer wanted close to $500.00. Purchased the coded cylinder online for $70.00 and fixed the door in less then five minutes. Great info. Many thanks!

Why is everyone talking about taking the door card off? I did mine in probably less than two minutes just from removing the torx screw.

Had a slightly different experience here, the actual whole barrel came out with the key one day. was using the key as both remotes weren't working. Fortunately managed to slice the key in half and get one of the remotes working, which meant I didn't have to break into the car. I took the grommet out, and could see the coded lock was broken, even the spring was out of alignment. decided to leave it "as is" and meant the barrel could be placed back in the car, rather than leave a hole exposed to the elements.
just waiting for my coded lock to arrive from Germany (10 day lead time), cost was 37.37 (31.80 +VAT). think when replacing it, I'll use some thread to tie the allen key bolt, to stop it from falling into the door when I remove it. will let everyone know how I get on, wish me luck.

i just ordered a keylock cylinder repair kit off ebay from turkey, it took about 3 weeks to arrive. removing the keylock cylinder from my door wasnt easy.. took me about an hour to finnally take it off it was just stuck in there. i thought there was another screw somewhere in there so i decided to take the door panels off... big waste of time, there was no other screws holding it in place. i put the door panel back together and kept pulling and prying with my screw driver and it eventually came off. it took about 5 mins to put in the new replacement parts from the repair kit. i poped it in the door to test it out and it works great! but while screwing the allen in, it slipped off from the screw driver and fell through the hole. had to take off the door panel and find the screw and put it back together. in the end, i was happy. the dealer wanted to charge me $130 for a new keylock cylinder. i bought a repair kit off ebay for 15 bucks and saved $115!

I did look at the ebay lock repair kit and was 20, thought the genuine article for 37.37 was a less risky option, glad to hear the lock repair went well. It also worried me that if bits of the lock drop down into the door it would be a take-apart of the door, and seems from other posts its not recommended to disconnect the airbag when you're working on the door unless you want the airbag light lit.
Apologies for not mentioning this earlier, but think all the people who have contributed to this post are great, as would have been sending the car into a dealer without this info.

Firstly just to say thank you to all who have contributed to this thread, the information was invaluable and allowed me to replace my coded lock without any major problems (took about 25 minutes).
Couple of notes whoever attempts this in the future;
Make sure you have your windows wound down and at least one door open before attempting this procedure if you dont have a working remote. The reason being, as I found out, was that once the coded lock (aka lock barrel) is removed from the car, the plastic shaped x which it engages with was out of alignment, and took me a few minutes to work out what position it needed to be in (i.e. which way the + should be so it locked and unlocked correctly). Fortunately, with the windows down, I knew when the lock position was engaged as could see the windows rising.
Secondly, Im not sure if its on the newer cars, but the allen key bolt that secures the coded lock is held captive by a plastic mount (fortunately for me as was worried this allen key bolt was going to drop into the door, and require me to strip it down). I also used the allen key bolt to gently help push the lock barrel away from the door, rather than lever it out from the outside of the door.
Good luck to all who attempt this procedure, the instructions on this forum saved me a lot of time and money.

My lock cylinder was broken. I was removing the allen screw and of course dropped it in the door. I have now repaired the lock cylinder and am ready to reinstall it, but have no allen screw. Does anyone know where I can get another allen screw? If its easy to get another allen screw that will work I would rather do that than have to take the door panel off.
