This is 1 of 2 locks left standing out of the batch I picked up from Ebay a while back. The Abus diskus is the other lock I have yet to defeat. I've been working on both of them for quite a while now, I think the Abus will fall soon.
I'd taken the Saker apart in the past and noticed a bit of slop behind the cylinder between the release latch and the cylinder that I thought I might be able to use to make a bypass for this.
I was right.
I finally got around to it yesterday and made this:
|Sorry rest of the world, I don't have a cm/mm ruler available at home.|
I used a piece of spring steel from windshield wiper blades and a Dremel to grind it down, then some 100, 220, 320 sandpaper.
The narrow part is about 1/16 of an inch wide, small enough to turn in the keyway of the lock cylinder.
Here's how everything fits together.
You can remove the plate that keeps the lock cylinder in place by opening the lock and unscrewing this screw at the bottom of the shackle hole.
|Screw at the bottom of shackle hole|
|Bottom of lock with plate to hold cylinder in.|
|This part here turns...|
|This part here. This is in the closed position. The shackle is fully inserted in this picture|
|This is in the open position and releases the balls holding the shackle in place|
The bypass tool can go all the way through the cylinder, fit in between the extended portion of the cylinder and the release latch.
|Inserted and turned to actuate the release.|
|Just enough room.|
Here's some pictures of the cylinder and the bypass tool.
And here's the finished result. Insert bypass, twist with a pair of pliers, and viola...
Now, I've been told that this is a knockoff of an American brand lock (5000 perhaps?). Which I'm sure is probably true, I haven't had the opportunity to see one and I have no idea if this same bypass would work on it.
I still won't be satisfied until I can open it with real picks, but it's always nice to have an ace in your pocket.
