IMMO guideSmart Key Not Detected

This guide equips lawful owners and their technicians with a structured diagnostic approach to the 'Smart Key Not Detected' message that appears when a keyless entry and push-button start system fails to authenticate the key fob. It explains how the immobiliser, radio-frequency receiver, and low-frequency antennas cooperate, then walks through ownership documentation, choosing between dealer and registered locksmith routes, and what a professional job should involve. Readers will learn to verify repairs, spot common scams, and prevent repeat faults through battery care and signal hygiene. The guide stays at the level of manufacturer-approved procedures and never covers bypass, cloning, or code extraction.
