AV-SCANNER / IMMO guides / Modules
This Auto Veteran guide explains why a vehicle alarm can trigger without an obvious break-in, tracing the fault through the bonnet switch, door and boot latches, interior movement sensors, and the immobiliser's own alarm logic. It is written for the lawful owner and the technician working on their behalf, setting out proof of ownership, the choice between a dealer and a registered automotive locksmith, and what a professional diagnostic session should involve. By the end you will be able to gather the right evidence, describe the fault accurately, judge a quote, verify the repair, and reduce the chance of a repeat false alarm.
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.
