Turn the key over to make sure that the part of the key that latches onto the keyboard is still in place. You should see a small plastic piece that will attach back onto the keyboard base. Compare the key to the base of the keyboard where you plan to reattach it to make sure that this latch is present. If it isn’t, then you may need a replacement key. Individual replacement keys can be purchased online. In order for your key to reattach and work, the keyboard base must still have its parts. Look to see if the rubber nub in the center is still there, as well as the small metal hooks that will hold the key.  The nub is in the center where the key will sit. The metal hooks will fit into the latch on the underside of the key. Some laptops may not have metal hooks. Instead of metal hooks, you may have a plastic hook. Line up the retainer bracket with the key base on the keyboard. Look at the keyboard base to see how the retainer bracket matches up to the base. Click the retainer bracket back into place. The retainer bracket is a separate piece that is usually clear or opaque white. It could still be attached to either the base or the key. If your keyboard has metal hooks, fit the hooks into the latch. Slide that side of the key in first. If your laptop has plastic hooks, slide your key on however you need to so that the key latches onto the hook first. After you fit the key onto the hook, gently press down on the other side of the key. You should feel it snap back into place, and you may hear a click. Test the key by pressing it several times to see if it is securely in place. The key should have a bounce to it. If the key will not reattach, you may need to take it into a computer repair shop. If it’s a Mac, you can take it to an Apple Store.
