I've added a page to the illustrated casino room key guide for keys from Wynn Las Vegas (including Encore). Check out the page at...

I'm sure there are other varieties of the room keys floating around out there as I probably haven't been checking the these keys as closely as I should (not only does the gold foil scan poorly but it's tough on the eyes). Please contact me by email if you have any additions or corrections to the information presented on the pages.

Thanks!
