Vintage 1980s Marriott Hotel Room Key #3116 And 2 Others Original USA

I’m pretty sure the blue key was from Marriott also. In fact, they all three could be Marriott but only one has the logo. It was from the Chicago downtown Marriott. They’re all in good used vintage condition.  Please check out all photos and ask questions.  I'll do my best to get back to you ASAP.
