RE: What would you do (lost key)
I would ask about what can be done to prevent the lost key from being used. Have them make a spare key (you don’t want to lock your only key in the car) Give them about week to find the lost key, it could turn up. How long was your R/T at the dealership before you took delivery? If it just arrived, sometime the keys can get separated in transit and it may show up later.
