Yes it's a lever lock, if you bough key blanks from a locksmith, and hand cut the keys, you might be able to get $20-$30 on ebay. Couldn't say for sure, haven't looked for safe locks on ebay for awhile. I'm assuming this is just a run of the mill SD lock and nothing special. Without a key, you'll probably get a bit less than that.

I wouldn't sell it. It was a gift. Maybe even a bit of a joke/test/audition. If he gave you that, he'll be pleased to hear how you're getting along with it.

I don't think many people pick them, but it would pick like any other lever lock keeping in mind there's two lever packs, and only one of the keys works the bold. Spend some time in the European forums. Lever locks took me forever to understand, but they are way cool.

[illusion]

It has two curtained lever locks.

The one on the left needs to be picked first, at which point the lever pack on the right need can be picked.

Has false notches so will make it harder.

If you could get hold of a keyblank you could make a pick for it, or just use a wire hook to turn the curtain, and another to lift the levers.

A very cool lock - I'd pay for it easily.

Not easy at all to pick - possible, but very hard.

Read my guide in the european forum, and then read shrub's guide - will give you an idea of what you're up against.

S & G 4440 .. one of the most common safe deposit box locks in the USA…the side farthest from the bolt is the guard key , there are only 5 or 6 factory guard keys so it is most likely one of them. Usually ALL the locks in a bank are the same guard key .The guard key doesn’t “ throw the bolt “ it only lines up the levers on the guard side.

The customer side ( always the side closest to the bolt ) can be any of 1000’s of different keys (6 levers 7 depths= 6 to 7th power keys).
If you were going to pick it .. you should use the guard key to get the 1st half and go from there. ( or just remove the guard levers for practice)

I have never picked one .. but they are fairly easy to open destructively …. Banks and customers like that .. it helps to insure the contents of the box are safe.

thanks very much for all the replies and help so far guys.

So you can guarantee that one side will bind before the other? It would sure make things tricky if you needed a pick in each lock and you had to go back and forth as different levers bound. That's what the picture seems to suggest.

The one on the left needs to be picked first, at which point the lever pack on the right need can be picked.

Looks to me like the one on the left is the one that moves the bolt. but I could be wrong, at the base it looks like that is the part that throws it.

get yourself a 4110 to practice on.it is single nose
they can be picked but i find it very difficult esp when in the back of yourmind you know there is always the other way to open these

[Lorek]

Picking would be difficult but there are easier bypass methods

[raimundo]

Lorek, tell us about the bypass methods, the nose puller is destructive, of course, but to me bypass sounds like something not destructive,

[Lorek]

Alas i was thinking of the nose puller, doh.

[globallockytoo]

These locks are not that difficult to pick with the right tools. It's just faster and more economical to use destructive entry. The locks do not cost all that much so picking them may just be an exercise in interest and not as a business aid.

I made a pick for the Lockwood 600/s78 projection locks, many years ago that works flawlessly on virtually "belly" lever locks....these S&G's are no different. You just require the use of two picks simultaneously.

I am currently in the process of creating a Bilock conversion for these locks. Hopefully I can sell the idea to banks.

[greyman]

Like gordon, I would have thought you can't pick one of the packs before the other. The guard section enables the renter section, but you have to have the guard levers in the open position or the second stump won't move back. Hard to believe globallockytoo's comment that they are not that hard to pick, given that you have to pick both sides (at once?). By all means, move this to advanced and tell us about it!

[TOWCH]

If you use "pick" loosely, no trouble believing it here. The locksmith I job shadowed showed me some of his SD tools but didn't go into specifics. If I'm right about what they were for, I can see it being "easy enough".
