If your wireless keyboard won’t connect, the fastest and easiest fix is to use a wired keyboard. Since wired keyboards don’t rely on Bluetooth, they work instantly—even when your Mac is locked.
How to Connect a Wired Keyboard to Your Locked Mac
Option 1: Use a USB Keyboard (Most Common)
- Get a USB keyboard – Any wired USB keyboard (Apple or third-party) will work.

Method 2: Use a Different Wireless Keyboard
Some Apple wireless keyboards stay connected to a Mac, even when Bluetooth is off. If you have another Apple keyboard, you might be able to use it to log in and fix the issue.
How to Use a Different Wireless Keyboard to Log In

Method 4: Use a Mouse to Enable Bluetooth
If your wireless keyboard won’t connect, but you have a working Bluetooth mouse, you can use it to turn on Bluetooth and reconnect your keyboard. This is one of the easiest ways to fix the issue without needing a wired keyboard.
How to Enable Bluetooth Using a Bluetooth Mouse

- Go to System Settings – Click the Apple menu and select System Settings.
- Select Bluetooth – Find Bluetooth settings in the left panel.
- Turn it ON – Click the toggle switch to enable Bluetooth.

Tip: If you don’t have a wired or Bluetooth mouse, you can use Voice Control to turn on Bluetooth.
Method 5: Reset Bluetooth Using Terminal (For Advanced Users)
If your wireless keyboard still won’t connect, resetting the Bluetooth module can help. This method forces macOS to restart Bluetooth services, which can fix pairing issues. You’ll need any working keyboard (wired or wireless) to enter the command.
How to Reset Bluetooth on Mac Using Terminal
- Connect a working keyboard – Use a wired keyboard or any wireless keyboard that’s already paired.
- Open Terminal – Go to Applications > Utilities > Terminal or use Spotlight Search (press
Command (⌘) + Space, type “Terminal,” and hit Enter). - Enter the reset command – Type the following command and press Enter:
bash
sudo pkill bluetoothd

FAQs: Common Questions About Connecting a Wireless Keyboard to a Locked Mac
Try resetting the System Management Controller (SMC):
- For Intel-based MacBooks → Turn off your Mac, hold Shift + Control + Option + Power for 10 seconds, then turn it back on.
- For M1/M2 Macs → Simply restart your Mac.
This often fixes hardware-related Bluetooth issues.
Yes! You can use the Apple Remote Keyboard app or Universal Control (if paired with an iPad). Just make sure both devices are on the same Wi-Fi network and logged into the same Apple ID.
Mostly on older Macs or after system updates that reset Bluetooth settings. Newer Macs have better Bluetooth handling and usually reconnect faster. However, low battery or interference can still cause issues on any model.
Yes, but setup might take a little longer. Some third-party keyboards need a passcode to pair, which can be tricky if your Mac is locked. Using a USB keyboard first can help you access Bluetooth settings to complete the setup.
This can happen due to low battery, Bluetooth interference, or outdated macOS software. Try changing the batteries, resetting Bluetooth, or removing other wireless devices that may cause signal interference. Keeping macOS updated can also help fix Bluetooth bugs.
Not exactly. The Magic Keyboard can remember multiple devices, but it only connects to one at a time. To switch between devices, you’ll need to disconnect from the current device and pair it again manually.
For Apple’s Magic Keyboard, turn it off and back on—the green light should flash, indicating pairing mode. For other keyboards, look for a Bluetooth button (usually on the back or bottom). Hold it down for a few seconds until the indicator light starts blinking.
Yes, it might. Cheap or unshielded USB hubs can cause signal interference, making Bluetooth devices lag or disconnect. If you’re using a hub, try plugging your keyboard directly into your Mac for better performance.
