Needing a new key? We've got you covered! This key contains an embedded micro-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. This specific key holds a Philips 46 crypt chip and has a wide range of compatibilities with multiple Buick, Chevrolet, and GMC vehicles. This key also has a high security key blade, a preventive measure against ignition picking and key duplication. The key blade will need to be cut by a locksmith or automotive professional.
