Phone as key

[Masstify]

Hello all,
So this happened....I used phone as key to leave my house and travel to a meeting. After meeting, going back to my ME the "phone as key feature" would not work. The Alert was "no key detected". Leaving me stranded and unable to unlock the car. I have had the car one month and had no issues with phone as key until then. Now I don't trust it and feel I need the key fob also. Has this happened to anyone else? Don't know what I did wrong. Any insight would be appreciated.
Thanks in advance!

Yikes. That sounds terrible. Curious, was bluetooth enabled on your phone when you got back to your car? Probably was, but just checking.
