Immobilizer System (Without Keyless Access System): Overview

An ignition key mechanically prevents strangers from starting a vehicle. An immobilizer system adds a second electronic layer of security to the vehicle. If the ignition key matches mechanically, but the electronic check does not match, the PCM suspends fuel delivery and shuts down the engine.
