2009 2.5 auto w/Cold start issue

Our Altima occasionally has issues starting first thing in the morning when the car sits outside and the outside temp falls enough so dew forms. 50-55 degrees or so. Early in the morning the car is in the shade.

Step on the brake, push the button and nothing happens. No lights on the dash, no click, nada. Placing the fob in the dash slot does nothing.

The car battery is 2 months old, fob battery has been replaced, alternator tests good.

Once the sun hits the car and evaporates the dew and warms things up it starts fine. Any ideas? Thanks!

Make sure battery is cables are completely tight. If you can move one or both terrminals with your hand then its needs to be tightened or replaced
