  3. Scan tool will display PLEASE ENTER PASSWORD. Using arrow keys, select password. Press YES when correct 4-digit password is selected.
    NOTE: If an incorrect code is entered 5 times in a row, immobilizer ECU will detect tampering and enter start-prevention mode. Engine operation and special functions will be disabled. To clear start-prevention mode, turn the ignition switch to ON position and leave in ON position for 20 minutes. Connect a battery charger if necessary. Start-prevention mode will cancel after 20 minutes.
  4. Scan tool will display ARE YOU READY? Press YES to begin registration. When registration is complete, scan tool will display COMPLETE. If an error occurs during registration, scan tool will display CAN'T EXECUTE. If ignition key is already registered, scan tool will display KEY ID HAS BEEN REGISTERED.

To register additional keys (up to 8 different keys), insert next key and turn the ignition switch to ON position within 5 seconds, then press YES on scan tool. After all ignition keys are registered, press NO on scan tool. This will complete key ID registration. Turn ignition to OFF position and leave off for a minimum of 10 seconds.
