What are some common reasons why a key on my MacBook Pro might not be working?
The most common reasons for a key not functioning on a MacBook Pro include hardware issues, software glitches, or physical obstructions. If there is dust, debris, or liquid spilled on the keyboard, it can prevent a key from registering when pressed. Additionally, if the keyboard settings or the operating system are not properly configured, this may lead to keys being unresponsive.
Another possibility could be that the keyboard itself has a hardware malfunction. This can happen if the keyboard has sustained physical damage or is simply worn out over time. In cases where these basic troubleshooting steps do not resolve the issue, it may be necessary to consult a professional technician for further diagnosis and repair.
How can I troubleshoot a non-working key on my MacBook Pro?

For more thorough cleaning, use a soft, lint-free cloth lightly dampened with a 70% isopropyl alcohol solution. Wipe the keys and surrounding areas gently to avoid damaging the finish. Ensure that no liquid seeps underneath the keys during this process, as moisture can cause electrical issues.
Could a foreign object under the key cause it to malfunction?
Yes, a foreign object lodged beneath a key can definitely cause it to malfunction. Items such as crumbs, dust, or small debris can prevent the key from making proper contact with the underlying mechanism, leading to unresponsiveness. This is a common issue, particularly if the keyboard has not been cleaned regularly.
To check for foreign objects, you may need to carefully remove the affected keycap using a plastic tool designed for keys or a similar object. After doing this, inspect the area for any debris and clean it out gently. If you’re unsure about removing the keycap, consider seeking professional help to avoid damaging the keyboard further.
What are the signs that my keyboard may need repair or replacement?
Signs that your MacBook Pro’s keyboard may need repair or replacement include multiple keys not functioning consistently across various applications, especially if the issue persists after troubleshooting steps.

Consulting a certified technician can provide insights into whether a simple fix or a full keyboard replacement is the best course of action based on the specific issues you are encountering.
Is it possible to use an external keyboard as a temporary solution?
Yes, using an external keyboard can serve as an effective temporary solution if your MacBook Pro’s built-in keyboard is malfunctioning. Most external keyboards can be easily connected via USB or Bluetooth, allowing you to continue your work without interruption while you troubleshoot or seek repairs for the laptop’s keyboard.
External keyboards can also provide different features or layouts, which may enhance your typing experience. However, keep in mind that using an external keyboard should be considered a temporary fix, and it’s important to address the underlying issues with the MacBook Pro’s keyboard for long-term usability.
