Help me remove cylinder and make keys for antique yale lock

[Antique key maker]

This is an antique safe deposit lock. It is changeable and requires 3 keys for it to work. The cylinder / pin key is turned so that you can set the renter key, to any key. This way the bank didn't have to replace the safe deposit lock if renter lost his keys. I took a picture of 3 keys, 1 is the renter, 1 is the guard and 1 is a key that would fit into the cylinder, to make the lock changeable.

Anyway, I don't have a working key for the cylinder, so would like to make a key for it. I would like to find blanks (hopefully ILCO sells blanks) and then pop out that cylinder and somehow make a key from measuring the pins. This is an antique, so I will have to keep original pins.
I'm not a locksmith so I am not sure how I could do it. Is this even possible? What would be the best way to do it?

I will buy a key machine soon, like a foley belsaw 200 for this task.

I took pictures of the lock and cylinder. I also took a picture of a key that will fit into that cylinder but will not turn it as it may not be the key even for this locks, it does fit the cylinder. If Ilco does not sell blanks for this type of key, since it is over 75 years old, how would I find blanks for this? Maybe someone can look at the key and the cylinder key hole to see if they can match this to a blank. Is it possible to make my own blanks?

Please let me know what tools I will need and how I can pop that cylinder out. Please tell me how I can make custom keys without replacing the antique pins on this lock.

Why are the pins on this lock have spiral grooves around them?

Thanks for all the help. Any additonal informatio you will need please let me know and I will respond ASAP.

You have some small pintumbler keys in the photo, are these keys that can fit in that keyway? From what I can see of the keyway, thats gonna be a hard blank to find a copy of, but as always in situations like this, look for an old locksmith shop that has a lot of old keys stuck high on their racks and left over from long ago. The keyway almost looks like an old american lock wafer tumbler double sided key called the W blank. this is a short length blank so if you modify one to fit that keyway, be sure its long enough to lift all the pins.

looks like a peanut mortise cylinder. If you have a key that slides in, why not just rekey it to that key rather than trying to decode the pins and make a key to fit.

it will be a cold day in hell when you make a code cut key for that on a F-B 200, your depth and space have to be right, and you have to know what your doing. Save yourself some grief, don't ever buy a F-B 200 machine, I can't give mine away, nobody wants it. Take the lock to a locksmith and he can generate a key for it with a good code machine, privided, he even has the blanks.

Anyone know how I can remove this cylinder? Also is the Foley Belsaw 200 so bad when you have the extra micrometer attachments that can measure the spacing?

No, they are a little better with the spacing micrometer, but myself and some others I have talked to have real trouble in keeping these things in good adjustment, seems one day it cuts with accuracy and the next it doesn't, you can give it a shot, but I find it to be a real big pain! Also, make sure you get the micrometers that have the measurements in actual number, not the original ones that just have the notches, this makes a difference in accuracy as well.

You have a Yale #4511 safe deposit lock. Looks like a 997X will fit the keyway. You don't have to remove the cylinder; just pick the lock ( should be a real pleasure with that severely parcentric keyway!) and use a plug follower to push the plug out while retaining the top pins. If you want to remove the cylinder it is held in with a spanner ring. See the knurled ring with two slots in it around the cylinder? If you don't have the right size spanner wrench you can put a small screwdriver blade in the slot and tap it counterclockwise to loosen it then unscrew it. Works just like a nut.

I do want to call your attention to something I noticed, however. There appears to be a piece missing from the lock. There should be a piece that fits over the cam of the cylinder. As this is in the picture, the cylinder cam will do nothing when the key is turned. The missing piece looks like it will engage that forked shape piece of the lock (by the bottom rivet). In other words, when you turn the key, this piece will rotate and push that lever which will release the gates that engage the renters key. You put a new renters key in, turn until it stops and turn the cylinder key back. This will engage the gates to conform with the new renters key. Feel free to PM me if you have more questions!
