Anyone with all original lock cylinders might consider changing them out now. While 50s cars are really easy to hot-wire, if you are on a long trip and quite distant from home (like I was) when the ignition lock fails, it CAN get annoyingly tedious. Also, getting the old tumbler out after it broke was a real pain!

Hey Gary.I assume you know its the cylinder at fault here not the switch?Key wont go in is the cylinder worn.If it wont 1/4 turn to release the cylinder you may have to drill the pin out to pull out the cylinder.

  

Gary, normally you would turn the key about 1/4" to the right and will allow you to depress the brass pin you can see in the small slot at rear of housing near the spring, this then allows removal of the key and barrel, the reverse procedure appies to fit new one. regards bill.

I have a 1955 Sunliner and today the ignition switch key would not go into the ignition switch.  After some juggling around with the key it finally went into the swirtch but now it will not turn on.  I have another ignition switch assembly but I need to know how to take the guts out (tumbler assembly) .  It looks like there is some kind of pin on top of the ignition switch that holds the tumbler assembly in place.  Any help will be greatly appreciated.  Thanks
