This is the way I replaced the ignition lock in my 50 Chevy. It had no key when I bought the truck and I ran the ignition circuit through a toggle switch. Then I bought a used ignition lock with key from somebody on Stovebolt Swap Meet. This procedure worked great. I just used the key that came with the replacement lock to turn it to the right. I didn't remove the complete switch, only the lock.

I hope this is helpful.
