Key door lock cylinder repair W/ Pics

Ok, Im making this DIY because there is no other one that i could use help ful except that 30 second long youtube video. This should give you more of an understanding on how the mechanism works and what parts go where. Any questions just hit me up on here. Difficulty level 4

This is the lock assembly with the every part removed except for the inner sleeve in the barrel and the cylinder itself. IT sounds confusing but when you take it apart and look at the inside you will know what i mean. When you are putting this back together, it is very important to have the grooved slots of the inner barrel on the horizontal sides inside the barrel not top and bottom because if you have is top and bottom then you would put your key in side ways and turn vertical and thats just weird imo. lol


step 2
Place this piece in as follows and make sure it goes all the way in and sits flush on the previous piece. The grooved edges will let you know you have placed the piece in correctly.





It should look like this when ready for next step.



step 3
Depending on what side of the car you are doing, your kit should have came with 2 of the same pieces but look slightly different. If your kit does not tell you what side goes on the right and left then you must put it all together and if it doesnt work, take it apaart and redo with the other piece. (trial and error)
Place this piece in exactly how its pictures..everything will be tight and wont move if done correctly,


This is what it should look like


step 4
Place spring in just like i did in this photo. I re used my old spring because i did not feel like messing with the new spring since it was a tad bit tighter spring.


NOW THE TRICKY PART
step 5
Use a ball point pen to slide the little bent part of the spring clockwise and push down on the spring so it clicks and hold in place




THIS IS WHAT IT SHOULD LOOK LIKE AFTER YOU DID THAT


step 6

Take the 3 inch rod and press down on the spring pretty hard and slide the retaining clip on



Final step
Tap the tiny little rod back into the top of the assembly to prevent the retaining clip from comming off.

PUT KEY IN AND TURN, THE SPRING SHOULD MAKE THE KEY RETURN BACK TO THE VERTICAL POSITION IF DONE CORRECTLY, if not you did something wrong, tinker with it and if you have any questions hit me up..thx SHANE

I forgot to add that I did this with the key out of the cylinder..if you do it with the key in the cylinder it will make all the inside components turn and throw your alignment off. so before you start adding pieces, put the key in and let the prongs on the cyilinder pop into the grooves of the sleeve then remove the key and start rebuilding it. sorry

another question since you've done this.
the sensor that detects which way the key is turned, do you have a picture of it?
mine gets stuck sometimes so the car thinks the key is still being held at unlock position (all windows roll down and sunroof opens), then the GM5 system would not respond to remote.
I have to put the key in, wiggle it left and right to get the sensor unstuck.

The sensor is in the door lock latch/actuator assembly. The sensor does occasionally go bad and the entire thing needs to be replaced, no way around it. Here is a list of the various part numbers for that assembly http://www.bmwgm5.com/e46_actuator.htm

also when you lock the door, it will unlock itself. when you unlock the drivers door, it unlocks all four.

Where did you obtain the kit from? And how much is it? If i recall I only spent 99 bucks on a replacement cylinder for my vehicle when my original broke. Did not realize there was a repair kit available.

Nice. Thanks. I will keep this in mind if it ever happens again, which is unlikely since I finally replaced my key fob. Good write up though.

For those that wish to swap their tumblers into a different lock I think I can help you.

Attached are a photo of the actual cylinder holding the tumblers. What is not pictured is the sleeve that goes around that cylinder. Once you remove the parts on the end of the lock (steps are shown at the beginning of this thread) you should be able to pull out the sleeve containing the lock cylinder [pictured]. Please note that my lock cylinder is missing a cap on the end since it was damaged by a failed thief.

At this point, you still cannot get to your tumblers until you remove the cylinder from the sleeve. I'm thinking you could build a simple tool to help (though I haven't tried this). Get two strips of metal and with a hacksaw cut a number of slits into the metal strip as pictured, such that it looks like a comb. Do this to both strips of metal. I'm guessing you could then push it against the sleeve such that it will push the tumblers down. As long as you do this on both sides of the sleeve I think you could then push the lock cylinder out even though you don't have a key for that lock. Of course if you have a key for the lock you wouldn't have had to do all this, the key would simply pull the cylinder out for you. PM me if you have more questions and I'll try to help you out more.

In the picture I drew the brown parts are the tumblers that need to be pushed down inside the sleeve.

Thank you, OP! Your thread saved me ~$100! I had been having intermittent issues with the door lock until it finally gave out completely. Ordered a repair kit from an Ebay vendor. Lock works perfectly now!

Very nice write up! I was a locksmith for 15 years mostly domestic with some Asian vehicles. Locks are very basic as long as you have the parts and do not dump everything first... Advice.. take pictures as you disassemble!

Tough job ...

Some pictures are wrong in shanekhalifa99's post and the wrong spring is being shipped !!!

I spend more than an hour to figure out how to install this repair kit.

I bought the parts from osco_ltd from Ebay, London.

The guy has absolutely no idea how to install the kit.

1. The spring shipped with the kit is a wrong spring !! The spring's ends must point towards each other and not oposite directions. The spring used by shanekhalifa99 is the right spring.

2. TEST everything before installing the spring and the rod. I ended up having the wrong spring jammed under the retaining clip. I still can't believe that I managed to desassemble the parts jammed (took me 15 min)

3. On the pictures shanekhalifa99 installs the wrong middle plate. This middle plate is for the right side (Passenger). So don't follow shanekhalifa99's picture for this step. I spend more than 30 min to figure out why my lock was not working.

4. AGAIN, test everything before installing the spring and the rod. The lock should move left and right 90 degrees !! If it doesn't ,you have the wrong middle plate installed.
