How to Pick Door Locks

What You'll Need
A standard hairpin
A flat metal clip, like the one that is attached to a uniball pen

If ever you are left locked out of your house, your office, or any room, you can get back inside without calling the locksmith and spending money by picking the door locks. It is possible to open a door lock using a few slightly modified household items. The mechanism on which a lock operates is actually quite simple: when the right key is inserted, a series of four or five pins inside the lock are pushed upwards at a specific level allowing the cylinder of the lock to move. It is possible to push the pins upwards without a key to open the lock. Follow these tips, and you'll never be locked out again.

Step 1: Creating Your Tools

First you want to create your tools. Take the hairpin and straighten it out. Then make a 45 degree bend at one end, and fold the other end over to make a handle. This will be your 'pick'. Next, take the flat metal clip, usually taken off a pen, and bend it 90 degrees roughly 1/3rd of an inch long. This is going to be the 'torsion wrench'.

Step 2: Inserting the Torsion Wrench

Insert the torsion wrench with the short bent end into the lower portion of the keyhole. You want to apply torque on the wrench in the direction in which you would normally turn the key. If you are unsure about which direction this is, turn the torsion wrench in both directions. The direction in which it moves more is the direction in which you want to apply pressure to the wrench. Normally you don't want too much of the wrench to be inserted into the keyhole, but just enough to ensure that you can properly apply torque.

Step 3: Using the Hairpin

Insert the bent end of the hairpin into the keyhole above the torsion wrench, all the while applying torque with the wrench in the direction in which the key would normally turn. The bent end should be able to touch all the pins inside. You need to develop a feel for the pins, see how they move upwards when the pick touches them, and spring back into place when the pin is no longer in contact.

Find the pin which is hardest to push upwards. Once you have found this pin, push upwards on it with the hairpin, all the while applying torque with the wrench, until it sets in place. You will know when this happens when you hear a clicking sound.

Step 4: Applying Pressure on the Wrench to Unlock the Door

With the hardest pin out of the way, continue applying torque with the wrench and moving on to the rest of the pins. One at a time, push upwards on them with the pick until you click them all in place. It is important that pressure is always applied with the wrench, otherwise the pins will just fall back into place. You might have to vary the amount of pressure you apply if you feel a pin is not moving at all. Once all the pins have been locked in place, use the wrench to rotate the cylinder and unlock the door.
