When the key is inserted or brought into proximity, the Engine Control Unit (ECU) sends out a signal to the key. The key needs to react with a distinct, pre-programmed code. If the code matches, the immobilizer is disarmed, and the engine begins. Without this digital “handshake,” the car stays stationary, regardless of whether the physical key fits the lock.

Action 3: OBD-II Connection
The core of the programming occurs through the On-Board Diagnostics (OBD-II) port. The service technician links an advanced programming tablet to the car’s computer.
Step 4: Coding and Synchronization
