Transponder Key Technology

Most people don’t realize that their auto transponder key is actually a technologically advanced piece of equipment.

Inside the key is a computer chip  that is programmed with an embedded code.   When the key is turned to start the car, the car scans the transponder key to see if the code matches what’s stored in it’s computer.  If the transponder key code matches, the car starts…if not….no start.

Purpose of the Transponder Key

The main reason for the chip is to prevent auto theft.  Prior to the introduction of the transponder key, it was much easier to steal, copy and reproduce an auto key.  Today, attempting to reproduce an auto transponder key requires in-depth technical know-how and sophisticated equipment (see my video with my state of the art key maker).
