When the Roadster was delivered, I received three keys. Two were full-use keys that my wife and I use to drive the car (they have 3 buttons on each for locking, unlocking and opening the trunk). The third, smaller key, I believe, is intended to be a "Valet Key". I'm not sure if it is a Canadian-only requirement, but each time I start the car, I have to push the middle button on the key fob to disarm the vehicle. The problem is that the Valet Key does not have any buttons, so I can't see that it can be used for any purpose. So, unless I am missing something here... thanks for the extra mini-key Tesla, but I don't know what they thought it would be good for?
