The resqme tool does not work on car windshields. It is effective only against tempered glass commonly used in side windows. How do I remove the safety blade clip? First attach the key ring or the cable tie (or the lanyard if you purchased the Premium Accessory Pack) around the loop of the clip to have more of a grip. Then unsnap the clip (pull straight / brisk movement) using the key ring or the cable tie around the loop. Please note that without support of key ring or the cable tie it can be a little difficult to remove the blade clip and can cause the resqme to break. How do I know the type of glass used in my car? Most sunroofs and rear windows are tempered. To figure out what kind of glass is in the side window of your car, you can look in the bottom corner. There may be a label that says 'tempered' or 'laminated.' If not, roll down the window and look at it from a bird’s-eye view. If it’s smooth and looks like one piece, it’s tempered. If it looks like a sandwich with a ridge, it’s laminated. Is the resqme reusable? Yes! resqme is designed to be used more than 1 time! The spring-loaded spike resets automatically and can be used multiple times. The blade is very durable and can easily perform multiple seat belt cuts.
