Stor A Key

Carmax uses these lock boxes that mount on the window and you need a proximity card to unlock it, then you get the car keys. I'm wanting to do for my car park so everyone can just pick up the keys when they need it. It would also be good for their proximity card to track their use of the car. Can a product like this exist to the public or is it something exclusive Carmaxa
