Ideas on how to pull ignition switch tumbler with no key

Only advice I have is to carefully drill the lock so you can turn it. I've done this "scaredity" on 2 or 3 different locks with success but never sure I wasn't gonna end up with a paper weight.

Use small drills and work up. Use a "weak" drill or a light finger on the "variable." Hold lock opening down so cuttings fall out. Increase drill bit size and do again. Use screwdriver and see if you can turn it
