Okay so I've never had to use my AppleCare, and I've never brought a product to the Genius Bar at the brick and mortar stores. But I recently got a used apple keyboard, model #A1048 (not the current version) from an outside source. However, one of the keys is messed up. Whenever I press the "R" key, the "T" key also registers. The keyboard is pretty clean and not gummy. Can I just bring it to a genius bar and have them take a look at it? Keep in mind I don't have applecare for this keyboard.
