#Repairing keys on mac keyboard install#
Install the bottom arrow key as we did in steps 3-5. Install the key retainer on the target keyboard. Seat the plunger in the right position on the target keyboard and let the glue dry.Īt first, I tried applying some pressure on the plunger but it didn’t work, because the plunger just kept moving around.įinally, I just reapplied the glue and let the plunger to seat by itself for about 10 minutes without applying any pressure on it. The first time I wasn’t careful enough and the glue filled up the plunger. Most MacBook keys don't have the rubber key pad.
On my target MacBook Pro one of the metal hooks was bent so I corrected the problem.Īpply a small amount of super glue on the plunger edges. Most keyboard keys are comprised of three parts: the key cap (which is the key itself), the key carriage (a flat piece of plastic on which the key sits), and the key pad (a piece of rubber that sits between the key and the carriage). You can use a very small knife to separate the plunger from the keyboard.
Try to remove it from the keyboard as clean as possible, so the bottom side of the plunger remains as flat as possible. Very carefully separate the silicone plunger from the donor keyboard. Inspect the bottom side of the key, make sure that holders are not damaged.Ĭarefully remove the key retainer from the donor keyboard. Remove the bottom key from the donor keyboard. Push on the button until it snaps on the retainer. Make sure the holders engage with the retainer. Seat the side with holders on the edges of the key fist. In my case the left side of the key cap should be seated properly. When you install the key cap on the retainer, make sure to seat the side with holders on the edges of the key fist. If only the number keys aren’t working on your Mac keyboard, it is possible that Mouse Keys is turned on this is an accessibility function which uses number keys to control the Mac cursor, and you may have accidentally switched it on. These holders secure the key cap to the retainer (hinge). Go to System Preferences, Keyboard and Set Up Bluetooth Keyboard. Turn the key cap over and inspect small plastic key holders on the bottom side of the key.
