Simple desk lock

[freakparade3]

When the lock is picked it should slide right out of the plug. There is nothing holding it in the shell but the wafers. try picking it and smacking the end on the deck, careful, the wafers will fly.

Freak, already done that... no go... mared the hell out of the butt end of the lock and I had to file it down to allow the hardware to re-connect to it. I have several of these cam type locks now, and most will come apart when in between the locked and unlocked positions, the others have a retaining clip. This one doesnt have either.... it does not come out when in between the locked and unlocked position.

I don't know what else to tell you. Without having the lock I don't know what else to try. Hopefully Keysman chimes in, I bet he'll have an idea or two for you.

Look on the back of the lock ( end fatherest away from the keyhole) the picture LOOKS like there is a retainer there try pushing that down

See arrow

LOL, sorry bro.... I meant to put an arrow on that pick myself to point it out... thats not a retainer... thats the shim i slid into it from behind.... used a "coke" can to cut out the shim, and as I was sliding it around trying to get the cylinder to pop out.... and trying turn the cylinder and the shim at the same time... the tail end of the shim came off in my hand.... I figure I can use some small needle nose to pull it out....

[freakparade3]

That shim may be what is trapping the wafers so you can't remove the plug.

[serpentine5]

No, did the shim after it wouldnt come out thinking there was a wafer in there preventing it from coming out.... I have already pulled the shim out. It is currently picked in the open position between 12 o'clock and 3 o'clock.

[freakparade3]

With it picked run your pick over the wafers while you pull on the plug.

Locks made by Illinios, Duo, and some Chicagos had a very small spring steel wire in a groove around the face of the plug that sprang out into a similar groove in the shell to lock the plug in. However, I do not believe your lock is like this. Many newer locks plugs will come out of the shell from the fron by picking the retaining wafer. Due to the described age, I don't think this matches yours either.

I believe that the back of the plug may have been pressed to deform it out a little to make sure that the plug would not drop out accidently while assembling. Look to see if the plug appears to be spread just where it disappears into the shell. I suggest that some pressure be applied to the back end of the plug to force it out of the shell. Put the screw all the way back into the plug and lay the lock over a socket large enough to let the plug go into the socket, but not the shell, and tap the screw with a small hammer. Tap only enough to move the plug and not deform it. Spray with any lubricant first. If it does come out this way you can clean off the expanded metal to reinsert.

No go.... wont budge....

Raymond....
Looks like it was a retaining wafer....

Here it is after your method and a hammer got it to break the retaining wafer and pushed it out.



Here is the broken retaining wafer:





Ok, so.... for future reference.... how should I have taken this apart without breaking the wafer?

[serpentine5]

I hate that we cannot edit our posts here.....

As in the last pic, you can see the retaining wafer sits on the side of the plug from the tumbler wafers.

[serpentine5]

Just re-keyed it to fit the fire safe key I had.... only able to use 3 of the wafers, instead of the 5 but it locks, and the key works....

[Raymond]

WOW! I am surprised!

There should have been a poke hole to push in the retaining wafer! The problem with drilling a poke hole is that it is hard to guess exactly where to drill it and that on locks without a screw on the back, the drilled hole can cause the retaining wafer to go in while using the key.

Anyway, it looks as if you can continue to use it just as it is.

If we had all known that there was a retaining wafer, you could have used the shim idea to compress the retainer while turning the plug. You were on the right track.

About 40 years ago, I had a similar lock with a retaining wafer and no poke hole. I don't remember if I saw it through the keyway or what, but I somehow knew there was a retaining wafer. I took a wire, bent the end of it at 90 degrees and filed it to a sharp point. I was thus able to insert the wire, and twist it to grab and retract the wafer. Worked quite well, at least on that lock.
