The brake light switch won't cause the key not to turn. The brake light switch can cause issues with the vehicle not shifting from park once the engine is running.
I know this is going to sound crazy, but have you tried different keys? You can't believe how often keys wear out and people think it is something major wrong with the vehicle. Also, have you tried to lube the tumbler?
