IPhones are notorious for cracking, chipping and also wearing out their few buttons. My phone has a cracked screen and the home button is very hard to use. Luckily the latest iOS offers a feature called "Assistive Touch" which can activate any and all of these solid buttons when they wear out.

Simply go into Setting -> General -> Accessibility -> Assistive Touch and switch ON

This of course is neither a permanent solution nor a perfect one. Your best bet is to take the iPhone into your nearest apple store and if it is still within warranty, they will fix or replace the phone. If the warranty has expired… It will more than likely cost to do anything.
