Welcome to the forum!
Has this happened with both normal keys? If not, one may work fine and the other may have a low battery. I am assuming the "emergency" key is the valet key and entering with that may set off your alarm (if it is activated).
If the problem affects both keys, then it may be the car's receiver, which still should be under warranty for a 2018. If you can get it started with the physical key and everything seems OK, you should be able to drive it to the dealership.
And honestly, if you set off the alarm in front of the showroom, you will get quick service!
Good luck and let us know what you find!
