Hey guys I have a 2015 5.3 Silverado that I recently Purchased in August, and the other day I went out to start it and noticed the battery was completely dead. I go to give it a jump and tried to start it and it just clicked. Looked on my dash it said to roll the window down and back up to reset which i did and it just gave me a message saying the Theft Deterent System was on with a light on the dash of a vehicle with a lock on it. Not sure what do to or how to reset it.

 

So you could move the windows on a dead battery?

Get the battery fully charged and, if the "vehicle with a lock on it" light is still on, disconnect the battery. After a minute or so, re-connect and see what happens.

 

lock and unlock with your fob and make sure it starts

 

Fixed the issue, not sure if it was the dead battery that caused it or not but I followed a procedure to relearn the transponder ignition key and it started right up afterwards.
