Hello,

Will a M1 bump key open these locks? Some of them have a keyhole on their backPosted Image

Thank you!

I believe the locks you are asking about have a different keyway, so the answer would probably be no.
Bump it to the next level.

I know they don't take an M1. The key they take is rather minuscule. I'm pretty sure it has a four number designation... something like an M1665 or something to that effect. I'll edit this post when I find out what it actually is.

I've heard of people making bump keys for those locks. Apparently, despite the hard work Master puts into making their combination locks high quality in terms of being hard to "crack" by feeling out the gates in the tumbler systems, the keyway that is sometimes present on the backs of these locks is so easily bumped that by applying tension and giving the bump key a quick push, it will unlock the lock.

So much for security.

If you could get a clear picture of the keyway on the back of the lock, I could probably cross reference the blank in the catalog. The internet is failing me in coming up with the blank for the control keys.

Thanks for the help :)

for these padlocks you do not need a bupkey, you can simply make a shim for it out of a soda or beercan

here is my youtube vid of it in action:here

M4 keyblanks work when they are trimmed down and made shorter. I have sold these bumpkeys to people in the past; they do work as easily as other people have said.

I think that this is the key you should be looking for to open that padlock.

Yeah, I agree with you that this key will probably open the padlock
