Your car should have come with two fobs, but how many physical keys did you get? Just asking because I have two fobs but one key, and can't remember if the car came with two and I lost one, or if I only got one to begin with. If it came with one that seems pretty silly as the physical key is the only thing that allows the fob to attach to a keychain and also if you lose your fob you are also going to lose the only key you have.
i got 2 fobs w/ 2 metal keys inside them. but that doesn't help you to figure out if you never got one, or lost one. they don't come out easy though. from what i understand, a locksmith can make one for cheap.
