They are equipped with an electronic microchip that sends a unique number to the immobilizer system of the car to verify the identity of the key. This adds an additional layer of security that reduces the chance of theft and other forms of vehicle crime. Transponder keys, like any other electronic device, are susceptible to various problems, including those relating to the chip's function.
