Good afternoon everyone,

This morning, while getting ready to hit the road, I accidentally used my wife's Jeep key to try and start my 04 Durango. The anti-theft system kicked in. At least, that's what I think. But now, due to the cold, I am strting to think this could be battery related. It was fine two days ago and this morning, while I tried to reset the truck with the proper key, all the lights on the instrument panels as well as the radio seemed to be running fine.

Is it the Anti-theft system? I should add that it sounds like the starter is making a clicking sound as it tries to turn over the engine.

Thanks for any input!
