• one-time activation code
• service code
• emergency disarm code

Remove protection layer from the sticker carefully. Do not use metal and other sharp items to avoid occasional erasing a printed information under protection layer.
Do not share emergency disarm code and service code with anybody to avoid your vehicle security breach!
Due to security reasons the service and emergency disarm codes are generated randomly at factory, never stored in any database and therefore cannot be recovered once lost! A system main unit with lost service code and emergency disarm code cannot be normally used and must be replaced to a new one. Strongly recommend to copy it in a safe place and record in StarLine mobile app: **“Settings” - “General information” - “Device codes”**
