'17 Taco Key Fob Works Intermittently?

Anybody else got this problem because the dealership thinks I'm high. Sometimes, and I don't know what causes it, the drivers side door will neither open or lock until I take my keys out of my pocket and hold them in the hand I'm trying to use the door with. Did a search and only saw this problem on a '16. Had my Taco for a year now. Just started doing it in the last month or two. The only thing I can think of is maybe, just maybe its my cellphone being in the same pocket as the keys and it somehow blocks the signal? I am also thinking of either using the back-up fob or changing the battery? Do I need to update my software? Never affects the starter, just the door. Anyone else? Buehler?
