nissan key programming can be used in newer cars. They have an RFID microchip that sends a unique code for the car when the key is put in the ignition. It is designed to ensure that only the right key is able to start the engine and also prevent theft. Contact your local dealership or locksmith for the demonstration of this new technology.
When the transponder key is placed in the ignition, it sends an electronic signal to the chip within the vehicle's engine control unit (ECU). The ECU checks if the code on the key corresponds to the digital serial number of the ECU. If it does, the ECU will then release the immobilizer, allowing the engine to start. If the code doesn't matched, then the ECU will refuse to accept the signal and stop the engine from getting started.
