Why is this cheap lock so hard to pick?

Postby GWiens2001 » 20 Sep 2012 18:34

Bought a cheap set of locks for some when-bored picking practice, possibly (ok, definately) for disassembly. :mrgreen:
Image
On sale! 3 for $5 at Harbor Freight!
The bitting was tough - a "9" cut at the third bitting, followed by a shallow cut. But, even with a medium hook, could not open this lock. It didn't feel like it had spools, so what to do? Being a guy, of course there was only one acceptable answer - disassembly! :P
Image
First, had to grind off the rivits. Thank God for air tools! :wink:
Image
Next, to remove the bottom laminated layer, used a trick - a screw. Hammer it in to get it started, then start to screw it in. You can see the rivets receeding as the layer rises off the rest of the lock:
Image
Then you add another screw from the other side, pointed to the other end of the lock. This helps keep the layer peeling off the rivits.
Image
With the bottom layer removed, you can see and remove the lock cylinder:
Image
Wait a second... that is a PLASTIC shell/bible!!! Talk about cheap! :shock:
Image
As you can see, if you wanted to removed the pins and rekey this valuable lock, just turn the key upside down and the key pins fall out.

However, back to disassembly - looking inside the lock body, you can see the mechanism that operates the latch. (Yes, just one latch.)
Image

As an interesting note - this lock, like any fine piece of work, has all spool pins... well, sort of:
Image

The picture is not out of focus. It really does looks like the spool pins are melted. This is probably intentional, as normal spool pins would probably quickly damage the high-quality, precision, soft plastic cylinder. At least the plug and pins are brass! However, it did make this lock difficult to pick. Took the pics last night. This morning, I made a Gonzo, so will have to try again with a non-disassembled lock.

Gotta go. Happy Pickins!

LOL at the plastic shell. With a plastic shell, couldn't you open it by inserting a screwdriver then turning hard? ...Just let the pins rip through the plastic? Not sure if that would work, but after trying to visualize it, I think it would.

An easier way to take it apart than using the screws is to cut off the plastic bump/rub guard then (in a vise) just hammer the bottom plate off with a hammer & punch (the edge sticks out once the plastic is removed). Grind off the rivet tails first, of course. That works pretty quick on Masters, anyway. This looks pretty much the same. Running a screw into it is a neat trick though - I haven't seen that before.

The plastic bumper is not just a band on the lock like on the Master locks. If you look at the pic of the internal parts of the lock, the plastic is a full layer in the lamination. Heck, plastic is cheaper than steel.

Oh, wow - the plastic is actually a layer of the lamination? :lol:

I guess this lock isn't rated for high heat, huh? lol
I bet if you got it hot enough, the cylinder would just fall out.

I thinked that also, you could put your cigaret lighter under it and it would be open in no time.
Not so unnoticed thought...

Not all the plastics are thermoplastic... and setting it on fire would not be considered NDE :lol:

Talking about plastic locks, here is another one.
Mine was surprisingly difficult to pick too, due to the slippery plug. Raking it was super easy.

Cheers :)
