This chip does not need a battery; instead, it is powered by the radio frequency (RF) energy sent out by the lorry's ignition cylinder.

When a driver inserts the key into the ignition and turns it, the lorry's Engine Control Unit (ECU) sends an electronic message to the key. The transponder chip gets this message and reacts with a distinct alphanumeric code. If the code matches the one saved in the car's computer, the immobilizer is disarmed, and the engine begins.
