Removing cylinder from commercial knob.

[cheerIO]

Well, I finally got some commercial knob sets in so that I can replace the storeroom lock at my Re-Store.

This one looks good and I believe it functions as a storeroom lock but I can't figure out how to get to the cylinder to re-key it.

I thought it was the kind that you push the cam in and remove the innards so that you can push the knob off from the inside. But as you can see, I bent the tabs back, removed the first piece and don't see how it would come apart any more. The construction of the set is such that each piece is folded over the next and doesn't look like it comes apart this way.

There is a hole in the neck of the knob but only the key turns, the knob doesn't. So doing the 45 degree thing with the key while turning the knob and pushing in a probe can't work.

Anyone familiar with this set? I can't find any markings on it. Is there a reference for commercial lock sets available anywhere?

IIRC, you need to have the key turned, then press the hole in the neck of the handle to remove the knob. Then remove the key and let the KIK drop out. I may be thinking of another model. If so, hopefully someone will correct me!

This knob appears to be a 'store room' function knob, by the lack of a push button on the inside part. That is, the inside knob is always unlocked but the outside knob is never unlocked. The key will pull back the latch but not leave the outer knob in unlocked condition.

Gordon is probably correct. But I will expand on what he has said. If the hole in the neck of the knob is exactly at 90 degrees, the release button can be pressed in with a probe, when the plug is turned (by key or picking). This is more easily accomplished with the knob attached to the door or held in a vise, or you will need three hands to do everything at the right time. = Turn the knob, turn the key (opposite direction), push in with a probe and hold the retainer down, and pull out on the knob, all at the same time.

If the hole in the neck is at 45 degrees, like some of the Arrow brand, the lock may have to be disassembled from the rear to press in the release, as the knob wont turn. Do not drill another hole as it can then be taken apart at any time.

Spin collar with spanner wrench so it lines up with the other retainer. Then turn the key and poke the retainer.

Thanks for all the help guys.

I got the knob off and re-keyed. This should work out great and keep stuff from disappearing from the storeroom.

Good job!

Thank you for the update. It is so nice when someone actually lets us know if something worked or not.

Too bad I'm late to this.
It looks like you need to unlock the lock to allow the outside knob to turn.
Yes I know, he says it doesn't turn.
If I could see the inside better, I'd be able to tell if there is a push button there.
Some store room locks, when you remove the inside knob, the push button inside pops out, unlocking the outside knob.
Some once the inside knob is removed, you can push in the inside center push button with your finger, turn left and it will pop out, unlocking the outside knob.
Like an A series Schlage kik.

Now you can turn the outside knob, find the release in the hole, turn the key if needed, and remove the outside knob.
Only two hands needed.

Thanks I Pik U. That was the problem. Once I took of the inside knob there was a "hidden" push button for the lock in there. It didn't look like a lock push button, but once I moved a little lever out of a notch the "button" popped up allowing me to unlock the other side. Then, as you said, I could turn the outside knob to get to that release hole.

Hopefully this will come in handy for someone down the line.
