Lock Picking

Once before, I explained about "Loiding" a lock, or using a credit card to gain entry to a locked door.
Here at work I have an additional skill. I can pull lock tumblers. Say you are moving into a new desk, and the key has disappeared for the new desk. You can go back to your old desk and pull all the tumblers out of the old desk, and install them in the new desk.
One of the standard tools available in the tool room is a rivet gauge. You use this to find the depth of a hole through layers of sheet metal so you know what grip length to use on a rivet. The end of it has a hook. It turns out this tool works very well as a tumbler remover for some locks.
A little beyond where the Key goes in the lock, there is a spring tensioned retaining lug. It is like a tumbler, but can't be engaged by the key.
If you insert the rivet gauge as far as it will go with the hook in the same direction as the teeth of the key and push up, it will depress the retainer, and the tumbler will come out.
Reverse the process to insert the tumbler into the other lock.
Amaze your family and friends with this newfound skill. Be cautious where and how you practice this skill, as it is frowned upon by some people.
As a side note, the tumbler design and depth must be exactly the same on both locks for this to work. It takes a little practice to get it down.
