We are currently undergoing a lock change program here at work, and are changing from Lockwoods to *probably* Abloy pro disc locks (or something similar).
As a result, I have got my hands on some truly datardly lock cylinders...
They are lockwood (I believe 'V Series'), with controlled keys. They are seven pin locks, with between 4 and 5 spool security pins.
The interesting thing is that the pin stacks are not vertical, but offset (by about 7 degrees), so that every second pin in staggered.
Out of a hundred or so attempts, I have only managed to pick the lock once (after about 1.5hrs straight
), and from experience drilling them is a nightmare.
Are these a particularly common lock? I haven't seen them anywhere else...
