When the key is inserted into the ignition or brought inside the cabin of a push-to-start lorry, the car's induction coil sends out a burst of energy to the chip. The chip then sends a distinct digital code back to the car's computer. If the code matches the one kept in the ECU, the immobilizer is shut down, and the car starts.
