Rare HOLLENDEN HOTEL skeleton key with fob

I don't know anything about it once so ever just what Google has educated me on. Any help will be highly appreciated. Offered here is a nice old room key from the Hollenden Hotel in Cleveland Ohio. Key is 3 5/16" long and tag is 1 7/8" in diameter. The Hollenden Hotel was a luxury hotel in downtown Cleveland , Ohio . It opened in 1885, was significantly upgraded in 1926 and demolished in 1962. During the hotel's existence, it contained 1,000 rooms, 100 private baths, a lavish interior, electric lights and fireproof construction. As Cleveland's most glamorous hotel of the time, it hosted industrialists , celebrities and politicians , including five U.S. Presidents . The Fifth Third Center skyscraper currently occupies the hotel's former location.
