To key or not to key
 

The 89 325i convertible I bought has had the ignition replaced, therefore the key will not fit the doors or trunk. I ordered a new key from the dealer so I could lock the car. Now I have a key for the doors and a key for the ignition, which bugs the heck out of me. I pulled the ignition switch out, in order to take it apart, and grind off the protruding cylinders so the correct key would work. The problem is, I can't get it apart to get to the tumblers to grind on it. There is a black cover going around where the key goes in and that seems to be the part which is holding everything together. My question is, has anyone ever taken this thing apart, and if so how? I guess I could take it to a locksmith, however where is the fun in that? Thanks

the dealer should sell a kit with all the pins so that you can match all your locks. Sucks having mismatched locks.

Took the ignition switch apart, did a little grinding and now the same key work all locks. Thanks

i bet my key fits your lock as well. what color is the car again?

I agree, if you go to the dealer, you should be able to purchase key pins, then just take the lock cylinder apart and rework the proflie on the pins until the old key works.
