Keyboard Chatter

In a keyboard that is exhibiting a “chatter” issue, this is typically when the key input registers multiple times when you press the key once, or doesn't register at all when the key is pressed.  This behavior can be caused by debris caught under the keycap or dust/debris inside the switches. You can try and clean around the key yourself by following these tips:

• Use compressed air and blow debris and dust from around and under the key caps. Hold the keyboard at different angles to get the best results.
• Using a key puller carefully release the key cap. The large keys are hooked to a stabilizer bar, so be sure to keep the connectors in place on the keycap when the keycap is removed. It's helpful to remove the keys immediately surrounding it to allow easier access.
• Hold the switch down and use compressed air to blow out the switch toward the bottom of the mount.
• Apply a small amount of 99% isopropyl alcohol to a Q-tip and clean around the key switch.
• Snap the key cap back in place, and you should be all set.

Here are some videos that show a good method for cleaning your keyboard switches if any dust/debris is causing the key chatter:
