Anyone have this issue and what is the fix. 2003 GMC Yukon slt 4x4
bought a new key fob and Reprogrammed both the original and new one. Both of the key fobs work but when locking the vehicle the Theft det flash and The horn doesn’t honk and the alarm does not active. When unlocking/locking lights flashes like normal. No issues starting the vehicle or anything. In setting both the horn and lights are set. Work before I reprogrammed the key fobs. Tired reprogramming, resyncing then and just reprogramming the original same issue.
