we have 2 2025 bmws in our garage. having 2 of them and both of us a drivers of each is bad enough!!!!always bluetooth connection issues.. question is, she set her phone up as her key. when she walks to the kitchen which is near garage her car will light up and such. i haven't programmed my phone to mine as a key yet. can someone tell me what all features using the phone allows? will this be a double pain having 2 in the garage and walking past with phones? and how can you leave someone in the car with it running while you quickly dash into a store?
