    I'm having an issue with my keyless entry lately. i'll set the alarm and lock the doors when I get out of my car, all doors lock and the light will blink on the door. When I come back out after a few hours, the light on the door is not blinking and the door won't unlock unless I unlock it with the key fob. it doesn't do this all the time, but I noticed it more as the temperature got real cold. Does this sound like a sensor issue or possibly a battery issue? Car is a 2015.

    first thing to do is change the battery in the key fob.

    You appear to be under warranty. You should take it to the dealer. The light not blinking on the door indicates it may be more than a key fob battery issue.
