Well Hello. the Key does look as though it could be a hotel room key, ( and I know your all waiting for the But.) But as has just been said it does have a lack of lever steps on it, what it does appear to have is a bullet ward? or is that my bad eyesight (from too much keycutting) What would be handy is a close up picture of the keybit end of the key,. Because if it is a bullet ward perhaps this was a way of using key differs? Though how a Master key would operate is an interesting question?
