Use light pressure only. If the key doesn’t pop out, try a different corner. To remove larger keys, such as the Shift key and Space bar, lever from the top of the key (the side nearest the laptop screen).

Do not touch it with a dirty or sharp object. This part of the keyboard is easily damaged. Clean with a lint-free cloth dampened slightly with rubbing alcohol. Pat with extreme care and wait for it to dry.

Very carefully remove a membrane from a key you don’t use by levering it off with a sharp knife. [3] X Research source It is very easy to damage the membrane this way, but this is usually your only source of replacement membranes. Use a toothpick to place a dab of strong glue, such as silicone adhesive, onto a sheet of paper. Pick up the membrane with tweezers and lower it onto the sheet of paper, then transfer it onto the keyboard. Let sit for at least 30 minutes, or according to adhesive label instructions. Reattach the retainer and key cap on top of this, and let sit another 20 minutes before using.

If you’re not sure, remove a functional key of the same size by gently levering out each corner with a screwdriver. Compare the attachment points on the two keys.

Before ordering a replacement key, make sure it includes a retaining clip. These are also sold as “hinges. " Alternatively, carefully detach a clip from a key you don’t use as often, and reattach it to the broken key. On some models, the tabs are separate pieces. If they fall out, you can slot them back in with a pair of tweezers.

Only one side of this piece attaches to the keyboard.

Using too much force here will break your retaining clip.
