Old US stamped american brass padlock

Postby Rusty_Shackleford » 28 Dec 2012 15:44

Does anyone have any info on this old all brass American lock? It is all brass and stamped US. I polished it a bit with my dremel and it cleaned up quite nicely. I assume it is WW2 era due to the Junkunc-American style logo and the wear on it. I visited 2 locksmiths today and neither could gather info on the keycodes stamped on the cylinder. The keycode is 2381. If anyone could provide some information on the lock and keycode it would be greatly appreciated.

The two locksmiths you visited should have at least offered to impression a working key for you. Impressioning is when you take a blank key, insert it into the lock, wiggle the key back and fourth and remove it, look for the marks on the key blade and file them, then insert key and wiggle again, then remove key, look for more pin marks left on the key, file where you see them, and repeat until you have a key that turns the lock and opens it, then either clean up that key and use it, or determine the cuts using root depth or depth and space keys and originate a new key by code.

I'm sure the (indirect) code books are out there somewhere for that lock (based on the numbers stamped on the bible) but not everyone has them.

Here's a key I was making to match an existing cylinder and pins for a Yale safe deposit peanut cylinder. I would insert the key into the plug and see which pins were sticking out of the plug, then file those positions until the pins were flush. This isn't impressioning, but just wanted to show you that a key can be made all sorts of ways, not just by looking up the code in a book.

Perhaps someone here will know the code or have other advice to offer, good luck.

My guess is that that padlock is a military padlock and that codes will not be available. Pick, impression or drill and take apart.
Nothing is foolproof to a talented fool. Wisdom is not just in determining how to do something, but also includes determining whether it should be done at all.

I guess I will give impresioning a go as I have a few AM3 keyblanks form a previous project. I would have just picked it, and removed the core, but there is a pressed in retaining pin that I do not wish to remove.

I have the exact same padlock, my dad brought it back from Vietnam circa 1969. He worked for the Army Security Agency in Saigon. Given the time frame, I wouldn't be surprised if these were indeed WWII era locks.
