Carmax is wrong. The credit card key has the same functionality as the regular smart key, just without the buttons. You can open any of the doors or the trunk and start the car, all with it nestled in your wallet. It even has an emergency physical key to open the door if necessary. Odds are it just needs a new battery.
I use it all the time. I only carry the regular key if I know I'm going to want to unlock the doors or open the trunk from a distance for some reason.
The credit card key does everything the fob does, except there are no buttons on it, so you can't point it at the car from a distance and do anything.
When I have it in my wallet, the car unfolds its mirrors and turns on the puddle lights and I can get in just by pressing the door handle button. It also makes the automatic trunk open when I stand in front of it.
The only thing I'd say against it is that it makes your wallet a little bit thick, and once you get it in there it's hard to get it out. But I love not having the thick fob in my pocket, so I like it very much.
