i have a 99 deville and there is no set time or occurrence that it will go into storage mode but sometimes i go out to go to the store and the remote wont unlock the doors cuz all power is cut off. so i have to start it and when i do that the factory alarm goes off until it recognizes the remote and it unlocks the doors. mind you that really pisses off the neighbors at 1 or 2 in the morning. i tried disabling it from the dic and it still does it. im really lost. i just got my service manuals i ordered and im starting to go through them to see if i can trace the wiring part of it, but would like an easier fix if anyone could help. thank you
