How to remove lock cylinder without drilling the roll pin out.
Tools required:

1/8“ drift punch or pin punch
Hammer
Flat blade screwdriver

OK, I posted long ago about this, I heard of how to do this from a BMW independent mechanic long ago, after I had already drilled out one or two.

I have done it once or twice before, but decided to take my time & document it this time with pics.

It is much quicker, easier to do, then using a drill, IMO.

Other reasons:  less mess, no chance of drilling into the lock and ruining it.
The lock is not damaged either, it was designed for this to be done this way. Maybe someone with the blue books can verify if it is mentioned there.

All I did:
1.  Insert key, turn it to fahrt.
2. Line up 1/8“ punch, tap the hammer 1 to 3 times, you want the pin to go in barely 1/8" took me 3 light taps, & I emphasize “light” and only 1/8", no more. The pic that shows the punch through the hole is only to show the 1/8" size fits. Don't go that far with the punch to remove your lock.
3. Take flat blade screwdriver & pry lightly but firmly and pull lightly on key or other side/edge of cylinder, it should come out, with only little resistance in first 1/4“.       

 

Note the pic of the lock cylinder once removed, the pin is just flush with the cylinder.

 

I still need to address the issue of the pin, it ends up inside the lock mech.
If you are installing a new lock cylinder, this is not an issue.
If you want to reuse this lock cylinder, you need to either drill the lock pin out, which should be much easier now that it can be done on a bench, using a drill press and a vice to hold the lock, or at least a vice to hold the lock & a hand drill.

There are other ways to remove it, but that is the most obvious.

Also the last pic shows where you can find your Key Code sticker if you need to order a factory key.

I blacked out my last 2 digits, because I am cool :-)

A small screw (like those for the trunk floor), a pair of mini vice grips and a medium screw driver work just as well. I screw the screw into the roll pin just a few turns, grab it close to the lock assembly with the vice grips, then pry the pin out with the screwdriver.

sounds like an ez-out would work for the same process?

 

have not pulled a lock before, but will need to at some point to disable the steering lock (track thing...)

For T.Jones:  OT but you mentioned the trunk board screws, and Mike S. and I have been trying to locate some of the cup washers that go under those screws.  It's been over a year now and we've had no luck.   Don't happen to know of a source for those do you?

I am having trouble with my steering lock becoming stuck, so how do I disable the steering lock on a 1976 2002 without losing the key ignition?  Any suggestions?
