This morning I tried to lock the car while it was running. Took my husband's fob with me to try to lock it...didn't work. Tried to manipulate the lock button inside the car, even holding the door latch in the open position (works on another car of ours) and that didn't work. The only thing I just realized I didn't try was to take my own fob out of the car after starting it and trying to use that to lock it...oh, I guess I didn't try the button on the outside, either. Will try those options in the morning.

Still need to work on seeing if I can get an engine block heater ... it's looking to be a COLD winter!
