Phone key suddenly no longer paired?

[Jenkins43]

I find it happens from time to time after a software update. For your wife's phone, has she used her phone as a car key yet to drive the car without you and your phone in it?) If yes, then the car sees her phone. It should unlock the doors.

This actually worked for me; she got a new phone so we had to re pair it, we created her a profile, turned my phone completely off and she paired with the car, took it for a drive etc and now it’s working good for her. Thanks for the recommendation
