2001 01 Ford Mustang Uncut Transponder Key

HIGH SECURITY 'CHIP KEY' - By now, most people know their vehicle's high-tech keys are expensive at the car dealers- Now, you can get high-tech keys from us at a fraction of the cost. How does the high-tech key work? The key contains a tiny embedded electronic chip called a transponder. Each transponder has its own unique code--it's the key's 'fingerprint'. When the key is inserted into the ignition and turned, the transponder is energized and broadcasts its unique code to the car's receiver in the dashboard. If the car's receiver recognizes the code, it will allow the car to start.
