Is it Possible to Replace Just the Keyboard on Dell Inspiron 14 7472?

Hi there - I have a faulty keyboard on my Dell Inspiron 14 7472.  I wanted to know if it is possible to just replace the keyboard without having to replace the palm rest.  I am being told by a local repair shop that the keyboard and palm rest for this model are integrated but the Dell parts website only shows "Dell English-US Backlit Keyboard with 80-keys".   Any help or experience replacing this model's keyboard is greatly appreciated.
