Once the key fob is programmed into your car's keyless system, it transmits a digital identity code as well as a function-code to instruct the car to (lock, unlock or open the trunk). The car's receiver verifies the transmitter's identity through an authentication and encryption process. If it's authorized, the onboard computer unlocks vehicle and begins the engine.
