How to Lock Macbook Keyboard

Locking down your laptop’s keyboard is more than just a security measure. Sure, it stops others from snooping around in your files, but it also keeps you from typing out angry emails when you’re having a bad day. From protecting yourself against prying eyes to preventing an accidental email send, let’s look at how to lock the keyboard on your Macbook and why it’s important!


Many laptop computers, Macbook included, offer users the ability to lock their keyboard. This can be a handy security measure if you are working in public and don’t want anyone tampering with your computer while you step away. Fortunately, locking your Macbook’s keyboard is quite simple and easy to do. Let’s take a look at how you can lock your system and make sure it stays secure until you are ready to unlock it.

Reasons to Lock Your Macbook Keyboard

If you’re careful with your technology, chances are you rarely think about taking steps to secure your Macbook from accidental damage or unauthorized use. While not an issue for all users, it may be wise to consider locking your Macbook keyboard for a variety of reasons. Here are just a few:

  1. Prevent Accidental Damage: If you have small children or pets who may inadvertently cause damage by pressing keys on the laptop’s keyboard, adding a keyguard can help to protect against unintentional harm.
  2. Reduced Exposure to Dust and Spills: Locks and guards can help reduce the entry of dust and liquids into the keyboard area when the laptop is not in use.
  3. Prevent Unauthorized Use: Even if no one has physical access to your Macbook, having a lock-and-key security system installed on your laptop can help protect against unauthorized users gaining access.
  4. Theft Deterrent: Installing locks on portable computers makes them less attractive targets as they require more time and effort for potential thieves to forcibly remove them from their cases during petty theft attempts.

Steps to Lock Your Macbook Keyboard

Your Macbook takes many precautionary measures to help keep your device secure and protect its data. One of these is the ability to lock the keyboard in order to prevent unwanted keyboard data entry. Locking your Macbook’s keyboard is a simple, yet effective measure that can help protect your system.

Follow these easy steps to ensure that your Macbook’s keyboard remains securely locked when not in use

  • Open System Preferences from the Apple Menu
  • Click on Security & Privacy
  • Select the General tab
  • Select Enable Keyboard Lock
  • Set the Security Lock delay for after how long you want it to lock automatically (i.e., 5 minutes). You can also opt for “Upon Display Sleep” or “Immediately Upon Log Out” instead, if desired.
  • Click “OK” and close System Preferences.

You will now be able to lock your Macbook’s keyboard simply by pressing “Control+Shift+Eject.” From this point onwards, you will need to press this button once more, or use a password which you have set up in order to access it again.

Benefits of Locking Your Macbook Keyboard

Locking your Macbook keyboard will not only provide an extra level of security for your data, but it also provides peace of mind. With the keyboard locked, you can worry less about someone gaining access to your laptop. It’s also a good way to prevent accidental clicks and key presses that can lead to unwanted changes or errors in your system.

The process of locking a Macbook keyboard is quite easy and should take just a few moments. All it takes is a quick shortcut or two and you’re good to go. To lock the keyboard:

  • Press the “Option-Command-Eject” keys simultaneously on the top row of keys on your Macbook keyboard.
  • With this combination, all that typing power has gone on temporary hiatus and cannot be used unless you enter the correct password.
  • Once locked, you can rest assured that no one will be able to gain access to your laptop without entering the correct password or unlocking it with the “Option-Command-Eject” shortcut once again. Locking your Macbook offers an additional layer of security which can help protect both important data as well as its physical form factor from being lost or stolen—offering much needed peace of mind anytime you need it most!

Troubleshooting Tips for Locked Macbook Keyboards

If your Macbook keyboard is stuck or is not responding correctly, there are some troubleshooting steps you can take to determine the cause of the issue and resolve it. Depending on the issue, you may be able to resolve it with a quick restart of your device or a more detailed system check. In this guide, we will look at various troubleshooting techniques for when your Macbook keyboard is locked, so that you can get typing again.

First, you should try restarting your Macbook device. This will help to clear any temporary software issues that may have caused an interruption in the system and help it run properly once again. To restart your Macbook:

  • Go to the Apple menu and select Shut Down
  • Wait for your computer to power down
  • Press the power button to turn it back on

If restarting did not work, you may need to run some additional diagnostic tests and procedures to determine what could be causing the problem. One option is using Apple Diagnostics or Apple Hardware Test (AHT) which can check hardware components that are causing interference with performance or hardware functions like keypad input/output.

AHT will allow you to reset components while eliminating any potential software related issues that may have interrupted proper operation of multiple parts including keyboard functionality. To use AHT:

  • Disconnect any peripherals from your Macbook (e.g., USB devices)
  • Start up in Internet Recovery Mode by pressing & holding Option + Command + R keys during startup
  • Once the device launches into AHT mode, follow onscreen option prompts for system diagnostics & testing

If these steps do not resolve issues with a locked keypad, contact an Apple Certified Technician who can diagnose and repair more complex hardware related problems.

Alternatives to Locking Your Macbook Keyboard

Password protection is a great way to secure sensitive information stored on your Macbook. However, if you want extra security without having to enter your password each time, then locking your Macbook’s keyboard may be an option worth exploring.

There are several alternatives that enable you to protect your Macbook and keep it running securely without resorting to manually entering a password each time you need to access or use the device. The following methods provide various levels of security and can all be implemented easily with minimal effort:

  • Use a Screen Lock App: This app will lock the keyboard upon execution and remain locked until the correct credentials are entered. Popular apps such as True Key, 1Password and LastPass are great options for quickly locking away sensitive information.
  • Secure Your Wi-Fi Connection: By enabling a secure connection through the network settings on your computer or router, unauthorized parties will not be able to connect their devices to your home or office Wi-Fi network even if they have physical access to it. This isn’t as ideal as using an app for locking purposes but can provide some extra protection against unwanted access.
  • Use a Firewall: A firewall is a logical piece of code that controls network traffic flow between two endpoints (i.e., computer and router). It allows you specify which data packets are allowed in and out of the node, which can prevent malware such as viruses from entering or leaving the system and put up an additional barrier between online predators who may attempt to gain access through known vulnerabilities in other systems connected via Wi-Fi or other networks being used by an organization’s computers.
  • Enable FileVault Access: FileVault is Apple’s built-in encryption tool that keeps individual files from being accessed unless permission is granted by uploading valid authentication credentials (a password) into the system before unlocking file contents for viewing and/or editing purposes​ . FileVault ensures that no one is able to gain unauthorized access into files stored on Macbooks by requiring every user who attempts to unlock file contents passes certain tests of authentication beforehand.


Locking the keyboard on your Macbook is a great way to protect its sensitive components while also preventing curious fingers from pressing keys they shouldn’t. Whether you’re working in a busy office environment or simply want to avoid accidental keystrokes, locking your Macbook’s keyboard is a simple yet effective solution.

When needed, you can quickly and easily enable and disable the lock via a simple keyboard shortcut or Settings window. If you frequently work in public places, enabling the Screen Lock option will make sure that anyone who tries to access your Macbook will have to enter an administrator password before doing so.

Following these steps will allow you to easily protect your Macbook’s sensitive keys from being pressed accidentally or by an unauthorized individual. With these methods in place, you can rest assured that your Macbook’s keyboard is driving productivity safely and securely!
