Hi, Amy.
Look at the underneath side of the key. Are all the little prongs intact and not bent out of position? If they are bent or broken, you will need to
_buy a new key_.
You need to put the little ring back in first. (If you already have it in, you need to grab hold of the outside top and bottom and pull them up like pulling up an ironing board. Go on to the next paragraph about attaching the key.) If you don't already have the ring in, you pull it open like you would an ironing board. The front of the circle part should be down, and the outside frame on the front should come up. Take the two tabs that are now down in the back and hook them under the two metal pieces at the back of the hole on the keyboard. Take the flat front part of the circle part that is down and hook it under the metal tab on the keyboard at the front of the hole.
Next, snap the the key onto the ring part, attaching the front of the key first. Then rock it back and snap on the back part of the key. Pushing in the center of the key, push downward firmly to reseat the key.
Refer to the photos in this
_Knowledge Base article_ as you go, but, hopefully, this will help you understand the photos a little better.
Good luck!
