Dell XPS 15 9550 Laptop Key

Hi there! The 'N' key on my laptop has come off. I noticed it was getting a bit stuck and popped the key off. The hinge is still attached and in one piece but unfortunately I wasn't careful enough in reattaching it and the plastic clip underneath the key broke off so now it doesn't securely reattach.

Does Dell offer individual key replacements? Or do I need to purchase the entire keyboard assembly?

I am confident enough in taking apart my laptop and removing the old keyboard if necessary. Laptop is out of warranty and would like to know costs of key/keyboard and cost to have it repaired by the technician.

Thanks!
