This morning both key fobs stopped working with my vehicle. Land Rover app could not unlock doors or otherwise communicate with vehicle. I noticed the rear taillights are faintly lit. Battery?

 

Confirmed battery. I guess the dim lit tail lamps are a safety feature and/or visual indicator?? Had to manually unlock door and climb over rear seats to get to rear compartment. Never did figure out how to open tailgate without power. Lol.
replaced battery and all is well again, I hope.

 

Hook up your battery charger, and open tailgate in the future. fyi hope this helps someone for the future.
