AV-SCANNER / IMMO guides / Keys
This Auto Veteran guide explains how to add a spare key to a vehicle with an immobiliser (IMMO) system while you still have at least one working key, covering the system's operation, ownership and authorisation requirements, the available professional routes, and what happens during programming. It is written for lawful owners and technicians working on their behalf, and it prioritises dealer and registered automotive locksmith involvement where security access is required. After reading, you will understand how to verify the new key works, spot common problems and scams, and take steps to prevent needing this service again.
Guidance is general and covers many makes. Exact procedures and values vary by model, so confirm them in the factory service information for your vehicle.
