When the key is placed into the ignition or the "Start" button is pressed, the automobile sends an electronic burst to the key. The transponder chip reacts by sending out a distinct alphanumeric code back to the ECU. If the code matches the series stored in the car's memory, the immobilizer is shut off, and the engine starts. If the codes do not match, the fuel pump and ignition system remain disabled.

- Ignition Barrel Replacement: If the ignition system is changed, the digital handshake in between the brand-new component and the existing secrets must be synchronized.
The Reprogramming Process

- Clearing Old Data: In cases of lost keys, the technician clears the existing "known" secrets from the ECU's memory.
- Signal Synchronizing: The brand-new key is presented to the system. The programming tool advises the ECU to accept the brand-new transponder code.
- Evaluating: The service technician validates that the remote functions (lock/unlock) work which the transponder successfully bypasses the immobilizer to start the engine.
