Ingersoll Padlock

[KarkarnRed]

Hey guys,

A friend of mine recently gave me a rather hefty Ingersoll brand padlock. I've been collecting padlocks at boot sales and such for a little while now but thought I would ask the experts if they could tell me a little about this newest addition to my collection.

Here is a gallery of three images of the lock in question. http://imgur.com/a/KajlA#0

Hey guys,

This is the Ingersoll OS711. It's a 10 lever padlock with a sidebar. The key's got 5 cuts on each side, so you're dealing with 5 levers on each side of the keyway. Each of the levers are a 'C' shape and have their own spring. The sidebar is situated above the keyway.

There's also a closed shackle version (CS712).

I'm told it's a real *itch to pick because of dampening that really limits the feedback you're given. Maybe Squelchtone has picked one, and there's handful of guys who could say they've done it. It's a big challenge.

I haven't picked one myself, but I'd love to have one. You scored a really nice lock for your collection.

I had an idea that it was good but I had no clue just how cool it was. Thank you for the detailed reply The lock will be taking pride of place on my shelf.

Wow, very nice find! Let us know when you get it open :>

[KarkarnRed]

I'll have it open in a few decades

Have the closed shackle version, also called the "Invincible". It is a great lock, and I have one key for it. Have not yet succeeded in picking it open. When you get advanced access, look for a pictorial tear down,

You did score a great lock.

We wrote about it in NDE Magazine a few years ago, check out the break down photos and tips for picking:

and I have not picked one personally, but do have one kicking around here somewhere.

A very minor correction to MrAnybody, the sidebar is located at either 3 O'clock or 9'oclock depending on the keyway used, rather than above the keyway. I have several Ingersoll 10 lever cylinders knocking about, but have yet to pick one. It's on my bucket list of locks, so it will happen eventually.

Nice find! I have never seen one like it!

Much appreciate the correction, mhole. I'll keep that in mind. Hopefully, some day one will pass my way.

I have a couple laying around here somewhere. I have picked them and have a video of it being picked and then broken down after picking. They can be tricky to open but to be honest I think they are easier to pick than a medeco or atleast that has been my experience with the few ingersolls that I have had. It takes more tension than any other lock I have picked to get the levers to bind. Then it is a matter of setting all the levers on one side and making a mental note of which levers you were able to set, then picking the levers on the other side, then going back to the first side and rechecking the levers you had already set to be sure they dont need reset and then picking any more levers that will bind on that side, then recheck the levers you set on the second side and then picking any new binding levers on that side. Simply repeat this process until the lock opens.

All of the ingersoll 10 lever locks of this design that I have picked have been padlocks. I have never attempted a night latch or other assembly. If I recall correctly, the padlocks have a rubber o ring on the end of the plug furthest from the keyway opening which dampens feel and probably is what requires the use of heavier tension while the night latches and other assemblies do not have this rubber o-ring. Again, this is from memory when I was working with these locks 6 or 7 years ago.

If you have a key for this lock so you can clean it afterword, you might try working some heavy lock grease into the lever pack through the keyway and working it into the levers with a pick if you have trouble with levers resetting on you real easily. The heavy grease (something like the lock saver grease) is thick enough that it could slow the motion of the levers down enough/add enough resistance that you have better luck keeping the levers set.

Just my experience. Hopefully it helps out some. I need to find somewhere to host some of my picking videos again since I let my web hosting expire.

Thank you for the great and detailed advice I'm sure it will be a few years before I'm able to follow these instructions but its a goal to work to and I'm sure the information will prove very useful.

I think the video explains it better but when these were shot it was done via fire wire to the pc with a mini dv handicam so the files are huge mpegs which makes youtube kind of a pain. If anyone has any ideas for hosting or woulding mind hosting some stuff I have quite a few videos of myself picking high security locks, explaining what I am doing, and breaking the locks down to prove they were fully pinned, not tampered etc. Off the top of my head I know there is a medeco, first gen 14 pin bilock, ingersoll 10 lever, amongst others that I do not recall along with tip and trick videos on repinning locks, packing the keyways of dimple locks so the plug can be rotated without the lock puking its guts out etc.
