AV-SCANNER / IMMO guides / Keys
This guide explains how keyless entry and immobiliser systems work, why keyless theft has become a concern, and the lawful steps an owner or technician can take to protect a vehicle. It covers proof of ownership, choosing between a dealer and a registered automotive locksmith, what happens during a legitimate security update or key service, and how to verify the result. Readers will finish with a clear, practical plan for reducing keyless theft risk and for handling any immobiliser work through authorised channels.
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.
