Door Lock Removal Instructions

Model: BMW Serie 3 E30 - Years 1982-1992
Part: Door lock

Once you remove the door panel and disassemble the entire handle with the lock, you can proceed with extracting the lock cylinder, which is operated by the key: it is essential to have the key to extract the cylinder. First, remove the pin located at the back of the cylinder by pushing it with a punch or a screwdriver; at this point, insert the key into the lock so that all the tabs align and retract, allowing the cylinder to be extracted. Now perform the reverse operation for insertion: with the key inside the lock, insert the cylinder into its housing, aligning it so that it slides down to the end of its travel, and apply the rear pin. If you want to use the new lock but the old key, you will need to file the tabs to adjust the combination.
