To clarify, you cannot change your password. The password recovery and change systems are not in working order. We need to fix them when we update inter parts of the website and enable to Registration to open again, but they will not be fixed until then. We're looking into it, so hang in there. Unfortunately, there is no other way to change your password. If you are unable to log in on your computer, you may be able to use another computer to log in, if you have one. When you say that the key is "dead," do you mean that it won't work when you press it, or that your keyboard has an issue that won't allow you to press it? I would not suggest this if you are not very familiar or comfortable working with computers, but you may be able to fix it yourself without taking it to a technician to fix.
