This is the way to do it. You can also exit the car with the car running and the drivers window open, close the door, reach in and press the lock button, then pull the window switch auto up and accomplish the same thing. Just keep in mind you will need the metal key in the drivers outside door lock to unlock the door when you try to get back in because the key fob and keyless entry will be disabled with the engine running.

I wouldn’t leave the fob in the car. Take both the key and fob with you using one of the methods listed above.

The one feature I love on my 2015 Volvo XC60 that my wife’s A5 doesn’t have..... the ability to start the car from my phone. It does a configuration check of the vehicle verifying windows up, doors locked, hood shut, nobody in seats, etc etc. it will only stay started for 15 mins max. Works out great to cool down car on a hot summer day or vice versa.

BMW and Audi both told me German manufactures don’t do that because someone died... bla bla

But both Viper and Compustar have after-market solutions that will do exactly the same thing as your wife’s Volvo. I have the Compustar solution installed in my current Acura and it works perfectly.

The engine will stay running with the fob out of the car, but you might want to have the auto stop feature shut off when you do this. I don’t think it would make a difference, but better to be safe rather than sorry.
