This system includes 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 cars).

When the key is inserted or brought into proximity, the Engine Control Unit (ECU) sends a signal to the key. The key needs to respond with an unique, pre-programmed code. If the code matches, the immobilizer is deactivated, and the engine starts. Without this digital « handshake, » the car stays stationary, regardless of whether the physical key fits the lock.
