I do not find a keyboard replacement for this model. It will probably need an upper case replacement. I’d take it back, sounds like you got cheated. MacBook Air 13" Mid 2011 Upper Case Replacement MacBook Air 13" (Mid 2011) Upper Case with Keyboard
Your MacBook needs a new Topcase with new keys. An Apple Service Provider can help you with that. Probably the previous owner droped some liquid on the keyboard or travelled somewhere with high humanity e.g. Thailand, Singapore…
