This circuit requires no internal source of power, instead drawing energy from the electromagnetic field created when the key is placed into or brought near the ignition coil.
When a vehicle's ignition cylinder receives a transponder key, the onboard immobilizer system sends an electro-magnetic query signal. The transponder reacts by transmitting its unique identification code through a devoted radio frequency. The vehicle's security module compares this received code versus its stored database of authorized keys. If the codes match, the immobilizer launches its inhibition of the fuel and ignition systems, enabling normal engine operation. Need to the codes fail to match or no action take place, the vehicle stays in its disabled state despite mechanical adjustment attempts.
