Can't get key to turn to unlock steering and shifter.
Still trying to get ignition apart; key broke off! Lock cylinder spins around about 270 degrees but doesn't stop in the right spot to undo the cylinder lock! Now I know why I prefer BMW's! Removed assembly from another MB to use as a test fixture to get mine apart.
