I have seen them around quite often but have never had the chance to try and pick one.
That was until today,a customer brought in a steel van lock box.This is the type of storage boxes that are found in the back of workmens vans etc.They are solid secure safety boxes for work tools.
The box in question had been cut open because the customer had lost the keys to it.With the box now open i was able to unscrew the securing brackets on the back of the locks and remove them.The locks that were securing the box were two Van diskus locks.The pins were set in the side of the keyway,instead of at the top,similar to a dimple type lock.
Anyhow i thought that i would have a go at picking one of the locks,but found that using a normal type pick was useless because the pins stuck out so far that the pick was unable to slide underneath them.
I then tried sliding the end of one of my tension wrenches underneath the pins and simply pulling it back at a slighty raised angle,and to my amazment within ten minutes the lock turned and opened.
Not sure if this was a fluke or not i tried the same technique on the second lock.Simply using one tension wrench to turn the plug as normal and using another wrench to slide under the pins,and this time i opened the lock in less than a minute and can now open it every time using this method.
The box that these locks are fitted to costs a couple of hundred pounds,and is supposed to be very high security,so for me this felt like a good achievment.

I have found a link to a site that sells this type of strong box,the box its self is called a van vault box.
