unpickable locks

[n2oah]

From what I understand of euro cylinders... they seemed to be designed for the average person to replace right? Unscrew the retaining screw and slide the euro out? slide new cylinder in and tighten screw... Or am I missing some powerful magic?

Yup, it's that easy. Maybe some peoplel think you need to drill out the retaining screw

Abloy Protec (with or without CLIQ)- this lock may actually be "unpickable" because of it's DBS.

But if you understood how the DBS works and how easy it is to disable it you wouldn't say that.

I do understand how the DBS works, however I have only read about the DBS and have never actually seen it in real. I wish I had the cash for a Protec, so I could see exactly how the DBS works, I don't know how it could be bypassed. I'm sure it would still be very hard to pick even with the DBS disabled.

From what I understand of the lock from the TOOOL PDF, the disc block mechanism works because one of the two return bars which have limited range of motion, get picked up by the back disc and or the other discs and forced into the other return bar forcing it to ramp into the serrations in the disc pack, this locks the disc pack together at which point the first return bar is now free to continue rotating and only then does the back disc apply pressure to the sidebars. This makes sense to me looking at the pictures from toool and also at your pictures of a disassembled cyllinder. It's something I can understand. However, I don't own a lock, and all I've seen are some pictures and drawings. None of which focus on the disc blocking mechanism in any real detail which is interesting to me because I feel like it's the most important feature of the lock. If somone who KNOWS would confirm the accuracy of my understanding or correct me I would appreciate it.

I was looking at my Disklock Pro cylinder and noticed there is a way to disable the DBS--I may not be on the same page as you, although.
This is just a thought, it probably won't work. Keep that in mind as you read the next paragraph.
I noticed there is a small opening at the end of the cylinder under the piece that pushes against the groove that the locking bar fits into. From here, you can turn they cylinder up-sidedown and you will see the two return bars. If you insert the key and turn it, you will see the return bars move. The DBS (as far as I'm aware) working by pushing the moving return bar (there are two return bars, one stays stationary and the other moves) into a groove on the disc. If you were to insert a tool into the cylinder and move it all the way to the end, then push one of the return bars out of the groove on the discs, the DBS would be bypassed.

Just an idea....
