How to Reattach Keys to a MacBook (3 Steps)

Remove the plastic connector from the back of the key that has fallen off. The reason keys come off of keyboards is because the connectors have somehow wiggled out of place, allowing the key to fall off. Use a small screwdriver to pry to connector off of the back of the key.
Attach the connector back on the keyboard. The side of the connector with the two small holes in the corners is the left side of the connector. This will give you some orientation on how to place the connector on the keyboard. Place the connector on the keyboard so the small holes are on the left side. You will notice that these small holes line up with two metal tabs on the keyboard. Use the screwdriver push connector until the holes connect with the metal tabs.
Place the key back on the keyboard. Gently apply pressure from right to left until the key is back on the keyboard and snaps it into place. You should hear and feel the key connecting back to the keyboard. Type with the key to make sure it works properly and is fully attached.
