Door key Cylinder DIY 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.:thumbsup: 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

Did your clients supply you with the parts? :-)

I'm curious what the indications were that this was necessary. Or did the thing just fall apart?

I'm sure that will help people in the future to do it. I did it may be a year ? Ago and without that video by the Turkish vendor of the parts I d be SO clueless. The more DIY instructions the better!
