Locked Keys In Car. How Do I Unlock The Door?

Hook your fingers into the lip near the top, right-hand corner of your driver's side door. Pull until you have a gap that is 1/4 inch (.64 cm) wide.

Slide a blood pressure cuff inside the gap you've created. Release the door once the cuff is firmly inside.

• If you lack the finger strength to do this with your bare hands, you can use a plastic lever to create the gap you need. Do not use a metal lever, as it can mar the paint of your car's door. If only a metal lever is available, wrap it in a t-shirt or towel to minimize damage.

Squeeze the bladder bulb of the blood pressure cuff. As it expands, it should widen the gap at the corner of your door. Continue to squeeze until you have a 1/2- to 1-inch (1.27 to 2.54 cm) gap. Don't over-inflate the bladder. Over-inflating can bend the metal in your door, breaking your window or knocking it off track.

Untwist a wire coat hanger to create a long, thin probing tool. If you don't have a coat hanger, you can use a stick or similar object.

Slide your coat hanger into the gap you made with the blood pressure cuff. Use it to hook the lock button, or use it to press the automatic lock to unlock your car.

• In some cases, it may be easier to hook and retrieve the keys you've locked in your car--or to depress the door lock button on your key fob. It all depends on the structure of your individual car.
