My nav system had been asking me for a code a few times in the last week or so. Now both fobs won't work, nor the electric door looks, electric tailgate, nav system, radio. Everything else ok. Battery is fine, terminals tight and clean. These components are not on the same circuit so not a fuse. Interior lights, bluetooth, electric seat adjustments are all fine.

not sure what to do.

A power source seems to be intemittently being disrupted. Check the main fuses and fusebox conections

Thank you,
I had it checked by a mechanic and there's a fuse in the fuse box on the driver's side that was the culprit. It's a 10 amp fuse that is identified simply as 'lights' but supposedly 'wakes' up the other components,
I couldn't imagine one little 10 amp fuse controlled all those systems. But live and learn!

Turned out to be a $1.00 fix!

Fuses are important and the one you refered to is the memory fuse that keeps control modules alive when engine is off.
Glad to know you have the problem resolved.
