Cold start locks doors
This started happening last winter but has become more annoying this year.
When I start the truck in the morning I leave the driver's door open as I have my dog out on his leash at the same time. When the truck is attempting to start it locks the doors. Last winter I could just hit unlock and all was fine. This winter pressing unlock does nothing but when I press lock I hear it attempting to relock the doors. Last night I plugged the block heater in so it might start easier today. It started fine without locking the doors but when I went to open the door for my gf the unlock button wouldn't work until a few minutes later.
I'm thinking the battery is shot as it is the original. Any other ideas?
