About Chevrolet Key & Module Systems
GM's theft deterrent system uses the BCM as the central security module. The key's transponder is verified by the BCM, which then communicates with the ECM to authorize starting. When the 'Service Theft Deterrent System' message appears or the theft light activates, it typically means the BCM can't verify the key. We diagnose and repair GM theft deterrent issues on-site using GDS.
