When a lorry's ignition cylinder receives a transponder key, the onboard immobilizer system sends an electromagnetic query signal. The transponder reacts by transmitting its special identification code through a dedicated radio frequency. The lorry's security module compares this received code against its kept database of authorized secrets. If the codes match, the immobilizer launches its inhibition of the fuel and ignition systems, permitting regular engine operation. Need to the codes stop working to match or no reaction take place, the automobile remains in its disabled state despite mechanical adjustment attempts.
This one-way communication procedure showed incredibly reliable at reducing theft, though figured out criminals consequently established relay attack approaches.
