Broken Key

Hi everyone I'm new here and have a question about my laptop keyboard. My laptop is a Lenovo Z61m that is about 1.5 years old. Over the last 2 weeks or so the n key has become less and less responsive to the point that it now no longer functions hardly at all so I am just copy and pasting the letter every time I need it. Is there anyway I can change the function of a different key to just become my new n key or do I need to figure something else out?

Thanks in advance.
