Experiencing keyboard problems on your MacBook Pro can be a frustrating ordeal. Whether it’s non-responsive keys, erratic typing, or the entire keyboard ceasing to function, these issues can significantly hinder your productivity. In this comprehensive guide, we will explore the common reasons behind a malfunctioning keyboard and provide effective troubleshooting steps to help you get back on track.

While turning it back on, hold down the D key until the diagnostics screen appears. This tool will check for any hardware issues and provide you with a report. If it identifies a problem with the keyboard, it will suggest seeking service.
Another method to confirm a hardware issue is to connect an external keyboard to your MacBook Pro. If the external keyboard works perfectly while the built-in keyboard does not, it suggests that the problem lies with the internal keyboard hardware. In this case, contacting Apple support or visiting an authorized repair center is the recommended course of action.
Why is my MacBook Pro keyboard typing the wrong characters?
If your MacBook Pro is typing incorrect characters, it might be due to an incorrect keyboard layout setting. Go to “System Preferences,” select “Keyboard,” and then click on the “Input Sources” tab. Ensure that the correct keyboard layout is selected. If multiple layouts are active, you may accidentally be typing in one that does not match your physical keyboard.
Another possibility is that your keyboard might be experiencing a temporary glitch or hardware malfunction. Try restarting your MacBook Pro to see if this resolves the issue. If the problem persists, consider resetting the keyboard settings or running the keyboard diagnostic test in the Apple Diagnostics, as mentioned earlier. If you can’t find a solution, contacting Apple support for further troubleshooting is advisable.
What should I do if my MacBook Pro keyboard is sticky or unresponsive?
If you notice that your MacBook Pro keyboard feels sticky or is unresponsive, the first step is to clean the keyboard thoroughly. Use compressed air to blow out dust and debris from beneath the keys, and gently wipe the surface with a damp cloth. Ensure that the cleaning agents you use are safe for electronics.
