Technical Ignition switch removal

Does anybody know if a special tool is requiered to remove the cylinder from the dash ? Nothing I have tried works, it seems there is a trick or tool or something I'm missing. I've tried the paper clip thing in the tiny hole but nothing gives. I have to replace it due to not getting a key when I bought it.
Any idea's are appreciated !

 

pull the door lock, glove box lock, and trunk lock. they should all have a four digit number on it. i can't remember if the door or glove box matches the ignition. take the number to a lock smith and he can make a key for you.

 

If my memory is right the door & ignition are the same and the trunk & glove box are the same.

 

For the paperclip deal to work...you need to have the key in the lock. Don't know about a '57...but on later GM cars, you put the key/lock in the Acc position...then the little ****on is lined up with the hole in the lock face. Once you push the little pin in...you turn it to the left a little more...and wiggle it out. Without a key, you might have to drill it out. I've never had luck getting a key made from a door or glove box to work somewhere else. Seems like the one I'm trying to work doesn't ever match the new key made. Instead ive taken to collecting keys for years...so when I buy something without keys...more often than not..ill have one that works..

 

Pull a door lock out. Run it on a wire wheel. If you find a code, that may get you a key made by a competent , old time locksmith. I say may because I believe there are only 4 tumbler pins in the door and 5 in the ignition. You have to guess on the 5th one, and that's where the experience comes in.

 

^^^^ what Panther said ...
Usually 5 or 6 keys into the search, bingo !!!

 

There is only 5 or ten different keys for 50's GM cars. Back in the day I had a set that would open any 50's GM car.

 

Another good reason to go to a competent, seasoned locksmith.They might have a master set.
At the Pontiac dealer in the 60's, when they'd tow 'em in with lost keys, we'd just go through the set one by one.Usually didn't take long.

 

Man, so many options !! I think I will try the door lock first, although going online and buying several old keys and trying them sounds like fun.
Anyways, thanks for all the responses, I do very much appreciate yalls advice
