Q: How do you open a door with no locks, but 7 doorknobs?
|
|
|
|
A: Lean against the door, turn the doorknobs, and let the force of your
|
|
leaning hold the latches back.
|
|
|
|
Picking a lock works the same way, only instead of doorknobs, you have
|
|
pins. Apply a rotational force on the plug (lean against the door)
|
|
and push up the pins (pull back the latches) until they get stuck at
|
|
the sheer line. Once they are all at the sheer line, the lock opens.
|
|
|
|
Tension wrenches:
|
|
The tension wrench applies the rotational force. Wide bobby pins, hex
|
|
wrenches with the short end filed thin, small screwdrivers with the
|
|
end bent 80 degrees, or anything else that can apply a rotational
|
|
force while still allowing you in with your pick, will work.

Picks:
|
|
The pick is what you use to push up the pins. You can either push
|
|
them up one at a time, which is normally called picking, or you can
|
|
run the pick back and forth over them, hoping they get stuck at the
|
|
sheer line, which is called raking or scrubbing. There are many kinds
|
|
of picks, but the most popular are the:

Picks can be ground out of hack saw blades or clock springs, and bent
|
|
out of piano wire, paper clips, safety pins, bobby pins, or anything
|
|
else that's strong enough to lift a pin and small enough to fit in the
|
|
keyway.
|
|
|
|
Using the correct tension on the tension wrench is the key (pun).
|
|
The most common mistake beginners make is to use too much tension.
|
|
|
|
When you don't succeed right away at opening a lock, listen carefully
|
|
as you release the tension. If there are no clicks, you are using too
|
|
much or too little tension. Adjust the tension and try again. If
|
|
there are clicks as the pins drop back into place, you had some set,
|
|
and the tension is correct. Try again with the same tension, and work
|
|
at it longer.
