Has been in service for over a year now and is working like a champ. Great kit and well made. ### ⭐⭐⭐⭐⭐ Solid replacement kit *by C***O on April 23, 2026* Worked for my 2004 bmw 330ci. Great kit to fix broken lock cylinder. ### ⭐⭐⭐⭐⭐ Its right the first time! *by M***R on October 15, 2022* This kit works! I have a 2004 BMW 325ic and my door lock cylinder failed. I researched the automotive web and took note of these kits that would allow you to rebuild the lock cylinder parts that would fail and you could save money not having the dealer to repair this issue and spending big money to have new car keys cut and programed. It's a good thing I ordered 2 different kits from different suppliers, this one and another brand named Keenso. I spent a couple of days trying to get the keenso kit to work. The problem with that other kit is 1. The parts are not cut correctly. The flat slotted washer that is used to hold everything in place is a bit too thick. 2. The keyed tab pieces that are in that kit - one is for NA/USA,CAN made vehicles and the other piece is for European right hade drive. Only one would work depending on your vehicles build. The assembly is part the issue. When I reinstalled the cylinder back into the door the lock was 180 degrees out of the locking / unlocking position and I would remove it and make sure the actuator was in the correct position and try again. It would not line up no matter which position I would put it in. I re-assembled the cylinder 30 times and the results were the same. So I choose this kit. The price of this kit was $11.00 The other kit was $8.00. This kit worked and only took 10 mins to install and the lock cylinder operates like factory. Also this kit did come with a dowl pin which the other kit did not. I hope this helps you out. I would return the other kit but its not worth the time for the price.
