BMW E46 Key Lock Cylinder Repair DIY

[@KillerFuzzball]

My lock cylinder just broke this week, and I thought I was screwed. Turns out, you even have a video on this. I've been watching your channel for a while now, dude, and I owe the fact that my E46 is still running to you. You're a legend, thank you!

[@50sKid]

Thanks!

[@DannyWifi]

Everytime I feel like giving up on my car you always inspire me to keep it. I really wish you had over a million views for the hard work and lessons you teach us. We’re all grateful for you buddy, thank you !

[@50sKid]

+KidNameDaniel thanks man, me too! I do have about 4.6 mil views in total these days thanks to people like you ;-)

[@lexiaontube]

I finally ordered the replacement kit and for the first time in about 6 months I can once again lock my car. Your DIYs are so detailed and well lit - I know we all appreciate you!

[@10penn83]

That was not nearly as difficult as I imagined it would be. Thank you for posting this. You are a godsend to the E46 community.

[@aaronmassey7464]

This worked like a charm! The mechanic quoted me $300 to replace, thanks to you I fixed it for $8.99!!!!

[@startingtech3900]

yeah he has a shop and commercial building to pay for

[@ashgongora]

MAN. it took me two weeks to get this fixed. the first time i got a bad batch of parts, had to wait an extra week but finally was able to figure it out. my car did randomly pull all the windows down when i inserted the key, but now works like normal. thanks so much! great tutorial!

[@dbmcdonald]

I didn't even know there was a repair kit without this video. Bought the kit and fixed the door in about 30 minutes. Thanks for the help!!!

[@notdavelol]

Just watched this for my '01 330ci. My door jam is slightly different but I think yours is a sedan. Lock assembly was identical. I will say two things about this repair. 1) This man is VERY INFORMATIVE. I have watched several of his videos on the upkeep on my 330. 2) That spring inside the lock cylinder, is the spawn of satan. No seriously. Try not to get mad during this repair. Took me 3 IPAs and a lot of patience and cussing up a storm. He makes the spring part look easy. IT'S NOT. PERIOD.

Lol man you sound just like me! Thanks for the advice cuz I'm about to do this repair and I will try to remain calm

[@DiscoFang]

5 years on and your videos are still a reference. Had my E46 for 14 years and think it's time for preventative maintenance on the lock!

[@rebeccawolfe5537]

I just put the replacement parts in the door and everything works, even the key fob. I was just turning the key back and forth once I had it back in the door and didn’t realize all my windows went down and the sunroof opened. Just like the key is suppose to do. Can’t believe it was all caused by a little broken piece in the door lock cylinder. Thank you 50sKid, I watch all your video’s for help on my car.

[@andrewrobertson9827]

Just rebuilt my lock now. So thankfull for this video. Got the spring done in 2 minutes. Handy if you have two people. After the spring is compressed (used ballpoint pen), and you have the keyway shaft held in against the compressed spring, if you can get a friend to hold that assembly down , its much easier for you to turn the keyway shaft and get the keyway holder in.

[@monty_hendrix]

50s kid, the man with the masta plan. Thank you for all your work, this helped big time.

[@josevansco4395]

50's kid I thank you for taking the time to help us out. It was tough at first but persistence prevailed. I suggest to anyone doing this to first make sure everything fits correctly. That ball point pen makes all the difference. Good luck everyone don't let it frustrate you.

[@davidgerrard776]

Took me about 40 minutes to do this with a $6 repair kit from eBay. You saved me $120. Thanks again!

[@clownkiller0629]

I want to thank you for this video and the link. I went to a BMW dealership it was going to cost almost $200 for the part and $200 for labor. I am not mechanically inclined but looking at your video makes me think I can do it

[@wittyjulian]

Done. 10 minutes out and in. You have provided very useful content for many of my accomplishments on these vehicles, and for that I would like to thank you for your time, effort and consideration when documenting your experience. Let the world bless you with peace.

[@Guyver99x]

Just wanted to say thank you for this in depth video. This is the best key lock repair video with the best video/audio quality and camera work. I hate it when people cut away to do steps off camera and resume. I have a 2001 X5 so it's not exactly the same but good enough. This no doubt saved me a chunk of money. Cost about $10 to fix this. And another $15 to replace a dead VL2020 key fob battery from other videos on YT too. FWIW, I used J-B Weld cold steel epoxy and that did the trick perfectly. I put in the time to cut the weld points on the battery with an x-acto to be on the safe side. Thanks again!

[@50sKid]

Thanks. I tried doing the battery thing and f'ed up my key, lol. Video not posted.

[@copyingsnowcatforviews1825]

Thanks for this amazing video. I almost broke into tears after my key turned without resistance. I thougt another big bill is coming towards me... But thanks to your video i could repair it for like 8$. Thanks :)

[@skylinerthirtytwo2683]

Thanks for this video I fixed my lock with it. Sometimes when I locked the car remotely it would unlock right after and all the windows would roll down . I noticed I couldnt lock the car manually with the key so before replacing the lock actuator I tried this and it's working so far

[@reecethompson1720]

YES! Finally fixed it and within 20 minutes too so I won't have to worry about it again! Thanks man you are a huge help and I appreciate your dedication in helping all of the e46 community keeping these wonderful cars on the road :)

[@rjl5020]

lol I swear, you pop up on like every repair I've made on my E46. Thank you for the effort!

Thanks for the tutorial. Took me 10 minutes to fix the drivers side door lock with an aftermarket kit.

[@keithcarlson2002]

50sKid.... YOU ARE THE MAN! I have utilized 3 of your of videos and all were extremely helpful. You have saved me hundreds of $$ and enjoyed doing these repairs myself. Your videos are so much more precise and explanatory than others covering the same topic. Thanks so much for posting these instructional videos!

Yeah this guy does dealership quality work and his videos are by far the best on utube for an e46. Just wish he had a how to do e46 m3 crankshaft rod bearing replacement video.

[@toniocastro5426]

Once again Jason, you done it.!!!!! Thank you for helping us less fortunate with mechanicals habitat. You are a incredible BMW professional mechanic. God Blessed you.

[@lewis72]

You star !! This is EXACTLY what I need to do to my E60 530i. I've just collected it from the garage, where they were meant to fix this but they didn't. They change the mechanism inside the door but failed to identify the door barrel spindle failure. I'll do it myself and then tell them how crap they were.

[@GmanGggggg]

You are a lifesaver. Instructions were spot-on and I saved a lot of money. Thank you so much for your video and other videos you do. I also replaced my brakes with your help. And I adjusted my parking brake. Thank you again!!!!!

[@stchaltin]

First off, your videos have saved me so much money and I don’t even know where to begin to thank you. Would a broken lock mechanism affect the window operation? I rolled my window up (330i) from the outside using the key, the lock broke and now my window is stuck even with the electric controls on the inside of the vehicle. I bought a new window regulator and I’m prepared to replace that if this lock fix doesn’t solve the problem. Has anyone else had this problem? Cheers.

Thanks for this video. I have watched a few others but you are the only one who explained the proper orientation of the parts, in particular the inner LHD/RHD specific piece that breaks. At least when your old parts flew out you had the new ones waiting. Something that isn't fun is dropping an ID44 transponder chip on gravel. Ask me how I know!

Thank you for including the inner door mechanism aligned, you confirmed my conclusion on centering it between lock and unlock. One problem is my lock Cylinder fell out and became disoriented, and so far I locked myself out, and will climb through the trunk with the alarm sounding. Any suggestions on proper direction for the Cylinder?Thank you! Great video!

[@mattpistritto1424]

UGH lol such a helpful video. I thought I had fixed it then I tried it out in the CSR door and i broke the piece that breaks in the lock lol oh well. I took apart the working lock in my E46 part car and took apart the lock in my actual daily driven e46 that was broken and put it together and it worked until I put it in the door and that dang piece snapped lol. It was weird I had a few problems. Where the key sits in kept sliding out, and the part where one side of the LHD/RHD piece is bigger/taller than the other, mine were the same size lmao. I just put the side you were talking about where you said too but they were the same size. Oh well. I'm going to buy the parts kit and try it again I just wanted to try to save some money lol! Thanks 50s kid!!!!!!!

[@PhuPhillipTrinh]

how does one get the door open to access the screw if the door doesn't open in the first place? We tried putting a battery jumper to get the car to light up, but his remote only unlocked the truck and not the car's locks. Obviously when we try the key the lock cylinder is busted, so now besides smashing the window and the rear seats don't fold down what choice do we have? thank you for your videos they are very helpful!

Thank you for this great video... Maybe you can help with my problem. My E46 key won't turn at all, so I can't remove the lock from the car. I guess the tumblers are worn. Any advice, please?

[@robertemerson7083]

Thank you for the excellent instruction. This is the second time I've had to do this repair on my '03, and I had forgotten the steps. The trick of using the ballpoint pen for the spring was easy and very helpful. I had a second pair of hands and eyes which I recommend. It was harder than expected to get the cylinder out of the door -- we ended up levering the assembly out from inside the door (using the 4mm allen wrench) near the retention bolt.

[@SoundofGugu]

Absolutely brilliant- thank you- saved me $100's. i used the end of my hex set of keys- they have a perfect hole in the end to secure the spring with.

[@chrisanderson9923]

Appreciate the video. I've taken my lock apart and put it back together probably 50 times and cant get my key out unless it is horizontal instead of vertical. I'm thinking the cylinder is not aligned correctly when I start? It also only turns one way put the lock back in unfinished for the time being.

[@scottgshomewrenching1352]

Have you tried any other repair kits? I used a couple on a customers car, each one only lasted about a month. He was using the key only to unlock the car. In your opinion whats the best kit out there?

[@timboyle3114]

Both my e46's have had this issue! This is a really great tutorial - I got the 2nd bit in the wrong way round so the spring was not under tension. I got my 2nd kit of amazon and it did come with the roll pin and spring.

[@adaohd2538]

Third time your videos help me, dude. Thank you very much. Greetings from Brasil

[@TTsmashers]

While testing the key after the repair it got stuck. the key was stuck at 1 o’clock and I couldn’t remove it or turn the key so I had to break the collar to release everything. I don’t know what caused this so when I used the collar from the kit I made sure it was installed on the vehicle before I turned it and it was done

[@agen1man]

Just ordered the repair kit for my E53. Been driving around for more than a year with the broken lock cylinder and I'm starting to worry about the day when my battery decides to die and I'm left with no easy way in. Hopefully the kit ships fast enough!

[@kalumbabwale3729]

You definitely made that look easy. Been fighting with the spring for over an hour now.

[@aceshigh1970]

I've used several of your videos over the last couple of years and they're always great. Thanks for sharing them. One point of confusion for me in the lock cylinder video was the screw holding the cylinder in the door. I think the video said you just needed to loosen, but the screw needs to disengage from the cylinder to release it I believe. Even after it is out it doesn't fall into the door because the door frame is holding it.

[@joshuasanders102]

Let me tell you my story surrounding this fix. I have done it twice now. When I bought my car in January 2019, this fix needed to be done. My key was dead and did not work even with a new battery so I was limited to manually locking and unlocking it. I did it but could not get the spring all the way to the correct position. This will make you so extremely angry. It seems so simple but it is HARD. Now two days ago (November 2019), I locked my car and when I went to unlock it, the cylinder spun freely without any reaction. I called AAA and they got me in. I ordered the part as I assumed this was the issue but it was going to take two days to come. The next day, I was just planning on leaving my car unlocked and I did that but when I shut my back door, all my doors locked. So I had to call AAA AGAIN. The tow truck drivers greet me by name at this point. At this point, I just leave the window open enough so I can stick my hand in and unlock it just in case (even though it's below 0 here in Minnesota). I finally got the part today and got to putting back the dreaded spring. After 20 minutes of trying, I GOT IT. This was one of the happiest moments of my life. Great video as always. I am shelling out the $300 for a new electronic key so I don't have to deal with this every couple months.

[@Jay-gj1rl]

I know this video was 3 years ago but it helped me greatly in May 2019. Thanks for the video!

Thank you sir, I used the spring from the kit it seemed to have a bit less tension, perhaps stop it from braking too quick

[@rebeccawolfe5537]

I did order the replacement parts for this cylinder cause there is no resistance when I use the key in the door and won’t unlock the door on my 2003 BMW 325xi .. BUT my question to 50sKid or someone who would know is: My key fob will lock my doors but will not UNlock the door, could this just be the fob or something else?

[@erykahl]

Awesome tutorial, I was able to fix this myself (female). Went to 2 key shops they claimed i needed to get a new door lock and have my key reprogrammed. With a cost of $250 plus.

You should mention that a broken tumbler can lead to the micro switch being out of sorts and tripping up the EWS, leading to intermittent no crank. I believe it's called a "double lock" fault.

Fixed my lock using this today and helped a lot. Brilliant. Cheers.

[@skrigz]

I dont know if this will help anyone but I caught hell trying to push the long piece down to slide the locking piece onto it because the lock kept wanting to back out so I found a small socket and used it to keep the lock cylinder pushed in and then I got a deep socket to push the long piece down and slide the locking piece in made it so much easier

[@mpgoetti]

Excellent guide! Sharp, well-focused video - and yes, you did make it look too easy. :) I had to trim down the new replacement part that breaks on the OEM hardware - the wings on the stepped side were about 1mm too tall on my replacement - if I'd have figured that out sooner, I would have been done much faster!
