How to Fix Broken Keys on a Keyboard

Replacing or fixing broken keys on a keyboard is easier than you may think. Unless something major happened to the keyboard, it makes no sense to replace the whole keyboard. Instead, learning to fix just the broken keys themselves can save you money and time, especially when dealing with expensive models.

Instructions

Difficulty: Moderate

Things You’ll Need:

• Screwdriver
• Can of compressed air
• Cleaning fluid (safe for plastic and electronics)

1. Determine what the problem is. If the keys are stuck or slow, you may not need to replace them at all, but could fix the problem by opening the keyboard and cleaning the contacts carefully. Debris, spilled liquids and dust may cause the keys to get stuck and can be easily fixed with an appropriate cleaning, using electronics cleaning fluid or compressed air.
2. Turn off your computer and disconnect your keyboard. If you are using a wireless keyboard, remove the battery so there is no risk of electric shock when you are working on it.
3. Remove the broken keys by inserting a flat-head screwdriver under the keys and then pushing up carefully. In most keyboards, the key will pop out immediately. If that doesn't happen, move the screwdriver to a new position and try again, rather than applying more force and risk breaking the plastic below.
4. Look at the key retainer under the key itself. The retainer is a clear or white plastic part that acts as a connector between the key and the computer motherboard. If it looks smashed, broken or aged, take it out and replace both pieces. Otherwise, you may leave it in place and replace only the key. Keep in mind, though, that most keys come with a new key retainer, so it may make more sense to replace the whole thing.
5. Snap the new key retainer and key in place by positioning the key on the retainer and pushing directly down. You should hear a soft sound that indicates the key is fixed in place.

Tips & Warnings

• You may notice that the new key is slightly harder to the touch than the others, but it should not be a big difference. The key will adjust with use.
• If you have a hard time finding a replacement key at a local computer store, search online or contact your computer's manufacturer directly. If you do so, however, factor in the shipping price and consider whether it would be cheaper to buy a new keyboard rather than choosing to fix the keys.
