It appears so because this key (the one on top) was just given to me by a co-worker, who's wife was just in Vegas for a Convention and she stayed at the Excalibur.

I've included the narrow key (bottom) just for perspective. Is anyone familiar with the remodeling there to be inclusive of door lock changes? (To switch from narrow key-ways to wide key-ways usually means an all new lock change.)

Comments? Is this old news?
