Key reprogramming is the technical procedure of syncing a car's onboard computer-- the Engine Control Unit (ECU)-- with a particular electronic key or remote fob.

When the key is placed 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 transfers a special digital code back to the car's computer. If the code matches the one stored in the ECU, the immobilizer is shut down, and the car starts.
