e46 drivers side door lock cylinder problem solved

If your drivers side door lock spins 90 degrees in either direction and won't lock/unlock, then this information is probably exactly what you need.
Read:
My 325i keyless entry broke, so I had been using the key to manually unlock my car. I took it to the shop, and the mechanic wanted $500 dollars to fix it...$200 for the part, $300 for labor. I looked around on the internet and couldn't find any answers on how to fix it or what was wrong, but I did find out how to take out the cylinder myself. I took it out and realized that the only part that was broken was a tiny metal piece that connects the lock cylinder to the part that unlocks the car (i believe its called the actuator?). So i'm going to post a picture of what broke and I plan to go to a junkyard and take this tiny metal piece out of a wrecked 3 series. I'm 100% sure this is the only part that is broken, and this fix will be an incredibly easy DIY and probably cost me about $20 tops. Hopefully this guide helps out another bmw owner with the same problem, because apparently theres lots of people on the internet who had the same problem I did.

Ok, so I ordered the part for $29 on Ebay from osco_ltd and it took about a week to get here. I fixed the broken part and reassembled the lock. I installed it and it works perfectly. It took me a little while to figure out how to put the lock back together properly, and I had the most problems figuring out how the spring works. Here is the explanation on how to re-assemble it.

Unfortunately I have only seen these pieces listed on ebay outside the US.

Looks like about $29 US??

Awesome video. But, getting that spring set is a pain in the a$$. Don't know how you made it look so easy.

A small minor detail that may save you some future fanatics some time: You may need to turn the key in the lock COUNTERCLOCKWISE when installing it back in the door in order to line up the "teeth" of the rod with the door.

I have not done it yet nor seen any pictures on here. However, I have read that it's pretty easy to get the cylinder out. Read here (http://forum.e46fanatics.com/showthr...ght=key+unlock) , I'm planning to do this soon as my key does not open the front door, it just turns to the right/left without any spring action to bring it back to up/down position.

I am having trouble taking this cylinder out. Is this the hole that I can for find the hex screw to release the cylinder?

I can see the cylinder has been broken, but just cant seem to see the hex screw to unscrew it to take it out.

Scooterjcx, thank you for posting the video. It helped a lot. I rebuilt my lock using the repair kit from the ebay seller in Turkey and I'm back in business.

Took me may be 30 minutes and cost $41 (including super fast shipping from Turkey). The hardest part was to bring the spring to tension and when I did and thought I was all done I found out that I used the part for the right door lock instead of the left door lock part that was also included in the kit. Had to redo it, but by that time I got the hang of how to assemble it and it took less time to put it together the right way.

Hey guys,

I have the same problem. I removed the key and saw that one of the inner rings broke off. I am ordering the part today.

I do have a couple of questions:

1. My whole assembly including the cylinder, spring etc are all dirty. How do I clean this?

2. Do I oil the cylinder, use WD-40 or do I need to put grease anywhere?

Thanks in advance.

For most of the mechanism you can use white lithium grease. For the cylinder (especially where the key goes) use graphite powder.
