Our key has a bit of unintended functionality.
If you have this problem of the keys always hitting your right knee here's the solution.
You need to have the keychain in the left hole of the key. After you start up, simply press the button to take the metal key out of the fob. The car runs (and doesn't shut down after 20 min) and you can just set your keys in the little compartment below the shifter (or ashtray or whatever).
I find myself doing this all the time now.
Enjoy!
