When the key is placed into the ignition or brought inside the cabin of a push-to-start vehicle, the Car Key Programming Cost Uk's induction coil sends out a burst of energy to the chip. The chip then sends an unique digital code back to the Car Key Programming's computer. If the code matches the one kept in the ECU, the immobilizer is deactivated, and the car starts.
