How to Lock a Gas Tank Cap


When gas prices rise, so does the theft of gas. One way that thieves steal gas from your gas tank is by siphoning--using a tube to suck gas from your vehicle. You park your car and go to work, you come out eight hours later and find that your car won't start because you have no gas. You can protect yourself. All you have to do is visit your local auto parts store and purchase a locking gas cap.

Things You'll Need

  • Locking gas cap
  • Key
  • Open the access door to the gas tank when you need to pump gas. Most of these can be opened with your hand, but some require that you push a button inside of the car.

  • Insert your key into the keyhole of the gas cap.

  • Turn your key to the left (counter clockwise) until the cap opens. Some locking gas caps require that you make a quarter turn, others require a few turns.

  • Pump your gas and push the gas cap back over the gas tank. Insert your key into the key hole and turn the key to the right (clockwise) until you hear a click.

  • Remove your key and give the gas cap a tug. If you have locked it correctly, it will not budge.

  • Close the access door over the gas cap.

Tips & Warnings

  • Park your car out in the open. Thieves can stick drill a hole in your gas tank and drain all of the gas.
  • If you lose your key, you will not be able to get into your gas cap.
