Cold weather problems

When the weather turns cold my truck will not start. I push the key fob to open the doors and nothing. I use the key to unlock the door. No lights, radio, buzzers in the interior, and no starter or headlights. If I slam the drivers door several times, it will come back to life. I know it’s electical in nature because I have to reset the radio security everytime.

Have you checked the battery cable connections, including grounds?

I have checked all cables and fuses and replaced the battery last month.
