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 key holds a Texas 4D-60 transponder chip and has a wide range of compatibilities with Nissan and Infiniti vehicles manufactured between 1999-2005. The transponder is an extended security feature meant to prevent fraudulent ignition access to your automobile. The key blade will need to be cut by a locksmith or automotive professional.
