Beyond the mechanical cut, many contemporary secrets include an electronic transponder chip that produces an unique radio‑frequency identifier (RFID). When the key is placed and turned, the car's computer system verifies the chip's code before permitting the engine to start. This dual‑layer security-- mechanical and electronic-- lowers the risk of theft and unauthorized lorry usage.
