Modern lorry security relies on a system typically called a transponder system. "Transponder" is a portmanteau of "transmitter" and "responder." Inside the plastic head of a car key or within a keyless entry fob is a small microchip.

When a driver tries to start the lorry, the Engine Control Unit (ECU) sends an electronic signal to the key. The chip in the key gets this signal and responds with a special digital code. If the code matches what is saved in the ECU's memory, the immobilizer is deactivated, and the engine starts. If the codes do not match-- or if the chip is missing-- the car will remain stable, even if the physical blade of the key turns the ignition.
Types of Modern Keys
Not all keys are produced equal. The intricacy of the reprogramming service typically depends on the kind of innovation used by the maker.
