Phase 1: Retrieving the Key Code via Door Cylinder

Locate the retaining screw on the driver’s door edge and unscrew it to pull out the door lock cylinder.

Once the communication completes successfully, remove the key, re-insert it, and turn the ignition ON.
To finalize the immobilization sync, pull the key out, insert it back into the cylinder slot, and cycle the ignition switch from OFF to ON exactly 5 times. The security dashboard light will immediately turn off, signaling a successful pairing.
