Yeah, it isn't much of a problem to get keys or locks replaced with the same as what is in your car now. Somebody broke into my 300D last year by trying to break the lock. After an unsuccessful attempt, they broke the window only to steal my $30 Chinese garbage power inverter and an empty car stereo box (I have a feeling that's what they were after). Insurance paid for the window and a VIN-matched door lock which had to be ordered from the MB stealership. The glass shop had a hard time finding a right rear window for a 124 for some reason
