This being my first post here on lp101 I'll introduce myself before my question. (skip down a paragraph to get to the question) I've been picking locks for little over a decade and have hundereds of locks under my belt succesfully opened and and few dozen unpickable locks mostly being medeco. I have been successful opening several medecos and have a technique that seems to work that i picked up from a friend if anyones interested let me know. I'm interest in high security locks and there operations, design, and the puzzle that they are. Its the high security locks that have brought me here.....
There is a Baton Lock that I came across recently which uses a disk detainer locking mechanism. I am in need of any information related to disk detainer locks. I've searched the web and forums and ran across a few articles on there operation all on Abloy though and seen the videos online of the abloy locks being picked but none of them explain how tension help bind the disk against the side bar. There is a free spinning anti drill disk at the top of the lock followed by 8 detainer disk which rotate 90 degrees. I've played with the disk moving them around and the operation of this lock is unbelievable smooth even with the use of the key there is absolutly on binding or force to be felt against the key. As far as I can tell the lock itself doesnt even employ a spring the action of the side bar and simply uses the force of the shackle to hold it in place. Even if I manage to set the disk in the proper alignment do I then need to apply equal pressure to all disk to adviod over setting one and to rotate the lock?
The picking method I have heard of for this lock is to place all disk in a clockwise limit that turns to the counterclockwise until you feel friction. This friction is the side bar contacting the groove. After you have all disk set against the friction you than work your way back into the lock and rotate the disk in a clockwise rotation and if the are all close the set point you will hear a click and this will be side bar engaging the disk repeat with all disk and open it becomes.
Please let me know if I am wrong here but I think that method is bunk and here is the method I am working on. I believe the force of the sidebar is mostly taken by one disk and that this disk should present more friction than the other disk. All the disk should be rotated the far counter clockwise postion and than you should search for the disk with the most friction and than turn it clockwise until the friction disapears and this will be the side bar entering the groove. Than repeat this process with all of the disk advioding to bump any and the lock should open.
I know this has been a long post and a lot of me stumbling through my thoughts but I would really appreciate any information on disk detainer locks and there picking techniques.. Thanks everyone and good luck picking.
