how do i remove a broken key from drivers side door

A lock smith might be able to help you there. I'm not aware of any tricks to remove a broken key that's buried in a lock cylinder unless you dismantle it?

This is a long shot, but do you have access to a really strong magnet? If you do, start by approaching the lock from a distance a foot or so, then gradually bring it closer, all the while listening for activity within the lock like rattling or clicking. Approach slowly, and off you see the remainder of the key and it's out far enough to grab, that should do it. If it isn't, aim the manner directly over the remainder of the key, and approach slowly until the rest of it comes out. No guarantees here, but it's worth a shot. Let me know if this helped. John
