Unfortunately, these locks are designed to be removed in the "on" position and when you cannot turn them on, you have another set of problems. It's going to require drilling out the lock pin and you have to be very careful doing that because the housing that surrounds it is softer metal than the pin and that cannot be damaged or you will have to change the whole column housing. You might want to let the pros do this one.
