2021 Discovery LXE 40M

Occasional message on dash display stating "CHECK FOB". Also, occasionally when pressing start button, nothing happens. Will have to touch the FOB to the button then it works. FOBS are within 2 ft of steering column when message appears. Both FOBs have new batteries. Entry door locks/unlocks from 75 ft away.

Anyone know where the antenna for the FOB's is located on my coach? Maybe the antenna needs to be repositioned? Other suggestions?

Thanks

Doug
