Does anyone know how to remove the lock from a '93 grand prix? I'm talking about the lock cylinder, not the latch or power lock actuator. It looks like there is only a c-clip style faster holding it in but I can't seem to get it out. The lock isn't working anymore, and I already had my door panel off to replace my mirror and inside door handle, so I thought I'd pull the lock and take it to a locksmith to see what they could do.
