Ford/Lincoln/Mazda Transponder Key – New/Uncut

Description

This item is a brand new, uncut transponder key that is compatible with a variety of Ford, Mercury, and Mazda vehicles produced between 2000-2011. This key comes embedded with a small electronic chip called a transponder. Once this key is cut and programmed correctly to your vehicle, it emits a signal to the vehicle’s Engine Control Unit (ECU) when inserted into the ignition. The ECU will then recognize the unique code of the transponder, activating the engine. Transponder keys add enhanced security to your vehicle compared to a traditional car key. If the ECU does not recognize the transponder ID, the immobilizer will not allow the key to activate the engine, which prevents fraudulent key tampering and deterring theft.
