I need help with my Keyless Entry

[JennyV98]

I'm having Keyless Entry nightmares with my 2019 e-tron! Unlock works sporadically, especially after parking for a while. Key fob seems to communicate a little, the handle light flashes, but won't unlock. Locking works fine after failed unlock. Also get random "key fob not in car" warnings while driving. Dealership replaced parts but no fix. Could a dying 12v battery be the problem?

faulty 12v can cause problems out of the blue. have you contacted your local dealership about this issue? might need some professional hands to resolve this issue y'know?
