So how does a tool small enough to fit on your key chain shatter a tempered glass car window so effectively? The body of the tool houses a spring loaded window punch. When you press the bottom cylinder against a corner of your side or rear car window it loads the spring and then releases it slamming the hardened steel tip of the punch against the glass. This amazing little tool is called a Res Q me. Here’s How To Test A ResQMe Keychain Auto Escape Tool. There is a simple way to test a ResQMe key chain escape punch without leaving the comfort of your home and… without breaking a car window. Place the bottom cylinder (located at the bottom of the tool) on an old magazine, book or pad of paper. Then press down on it until you hear a “click”. The click is the sound of the punch releasing. Now look at the surface of the magazine, book or pad that you just used for your test. It should have a small impression in it as if someone tapped it with a nail. A good quality key chain car escape device will instantly reset itself so it is immediately ready to be used again. If you press a key chain auto escape tool against a side or rear car window in this manner it will shatter it. A word of caution: Do not test a car escape emergency tool against a hard surface like metal or stone as this can dull the tip and render it useless in an emergency.
