Any Company Tried to Create a Device that Combines Cell Phone + Wallet + Keys?

I have noticed smartphone wallets are starting to become more popular, especially among the minimalist crowd and there are a lot of different styles out on the market. I have also seen a few devices, like the keylet, that combine your keys with your wallet; but I have not seen anybody try to create a device that combines all three. It would need to be designed so that the keys are easy to access and use while connected to the device. Maybe spring loaded somehow so that you push a button and the proper key pops out. With modern cars moving towards a keyless transponder, one could build this into their PhoneKeyLet, eliminating the need to pull it out of your pocket and use it to start your car.

Anyway, here are some of my favorite attempts, but none combine all three:
