Default Cold key fob will not work until it warms up

Just learned something new about the car...again. Background: I carry an insulated bag with a few snacks...I put one of those freezer cold packs in it. There is a pouch in which I put my keys/phone while I'm exercising. The fob, sitting against the cold pack, got extremely cold. When I walked out to the car, pressed the cold fob, nothing happened...no lights, no doors unlocking, etc. It took about 5 minutes for the fob to reach operating temperature....no problems at all, except standing around a locked Corvette trying to look natural....

Automatic fob or manual fob?

Try a new battery in the FOB. Battery voltage drops when cold and if the battery is already weak...

Would the iphone Onstarr app have opened the door or you need to have an active OnStar membership for that?

That and just using the key in the RKE would have gotten the door open. If the battery was too cold to start the car, then you could use the slot on the steering column and get it started with the cold dead battery.

My friend used to keep his Fob in his unheated garage near his car.
Winter time when it was cold enough the Fob never worked... at first.
Changed the battery and still had trouble at first when it was cold.
Finally kept it in the house and no further problem.

Any battery looses power when it is cold.
