How to Unlock Your Car Door Without a Key

You lock your car only to realize that the keys are still inside. If you don't have a set of spare keys handy, you might begin to panic at the thought of calling a locksmith and spending a ridiculous amount of money to get the car door unlocked. Several methods can help you gain access to your car once again.

You will need the following items:

Cell phone
Tennis ball
Lighter
Screwdriver

Unlocking with a Cell Phone

Step 1:
Call the person who has the car's set of spare keys. If the keys are at home, call a neighbor and ask him to go next door and get the keys.

Step 2:
Stand 12 inches away from the car door lock with your cell phone aimed at the lock.

Step 3:
Yell to the person on the other end to hit the unlock button on the spare set of keys. This must be done in to the mouthpiece of the phone. The car doors will then unlock.

Unlocking with a Tennis Ball

Step 1:
Hold a lighter over the tip of your screwdriver to get it hot.

Step 2:
Poke a small hole in your tennis ball with the screwdriver. The hole should be slightly bigger than the opening of the door lock.

Step 3:
Place the tennis ball hole directly over the lock.

Step 4:
Push on the tennis ball as hard and as quick as you can. The air pressure will lift up the lock on your car door so that you can again enter your vehicle.

Warnings:
The cell phone method only works if you have a remote door locking system.

A tennis ball might only work if you have an electronic locking system.
