Unlocking the steering wheel

Depends on whether or not you want to try and save the tumblers. If you aren't worried about the lock itself, use the tried and true method that thieves use. Get a 4lb slide hammer with a large screw on the end. Screw it in where the key goes and have at it. Will pop the lock in nothing flat then you can use a flat tip screw driver to turn on te switch. Not nice, not neat, but it does work....
