This system consists of a transponder chip embedded in the key head and an antenna ring around the ignition cylinder (or a sensing unit inside the control panel for push-to-start vehicles).

When the key is placed or brought into proximity, the Engine Control Unit (ECU) sends a signal to the key. The key should react with a distinct, pre-programmed code. If the code matches, the immobilizer is deactivated, and the engine starts. Without this digital "handshake," the car stays fixed, no matter whether the physical key fits the lock.
