First, verify the complaint.

Second, verify installation ....as it gets colder resistance goes up!

Third, update module to newest firmware available reset and reprogram the module start to finish.

I have the exact same problem , first start in the morning does not work. Lights come on plus various other noises but no engine start. When I look at the dash I see the error code `Invalid FOB KEY`  (from memory might be slightly different)

It doesn`t have to be that cold.  I just find it weird that in only happens in the morning. Even when the truck ist out in -15 all day , I can start it no problem from the other end of my second story buiding!  I can`t remember when it didn`t start ok!  

At least you know what my error code is!

If a wire had a bad connection , d have to suspect the one going to the ignition switch!
