How to Open a Locked Car With a Mobile

Locked car keys inside your car? What if your duplicate keys are back at home and you are away with your car when this happens? Obviously, the remote of your duplicate key has a very limited range and thus cannot work when you are away from home. Don't worry, this trick can unlock your car without that stuff.

   Tell the person to press the unlock button on the duplicate keys while holding it near their phone/mobile. This may not work immediately, so tell them to tap the button continuously till your car unlocks.
