The T button on my 5-year-old MacBook Pro is hardly working. It was a pain even writing these two sentences!

Its not a temporary thing its been tough for a couple of months. What do people suggest I do to fix this problem, before taking it to the shop? Ive googled the problem and people suggest gently removing the key with a knife but that seems risky, if I break the key.

Any advice will be greatly appreciated!
