Bluetooth Not Connecting? Try These Steps:

• Charge the keyboard using a wall charger for 6–8 hours to ensure sufficient battery.
• Factory reset the keyboard: Hold Fn + Z + J for 4 seconds.
• Power cycle all devices, including your computer and keyboard.
• Disable auto-sleep mode: Hold Fn + S + O for 4 seconds.
• Test the keyboard with other devices (phone, tablet, iPad, etc.). If it connects, the keyboard itself is working fine.

For Windows Users

• Uncheck "Allow the computer to turn off the keyboard to save power" in power management under the device manager.
• Update the Bluetooth firmware if it's still possible for your keyboard to connect to your device: Keychron Firmware Update.
• Reset the Bluetooth drivers on your PC.

For macOS Users

• Check Mac's Wi-Fi and Bluetooth interference: Apple Support.
• Try these troubleshooting tips: macOS Bluetooth Troubleshooting.

One Key Does Not Work/Register/Input Properly

1. Try to pop the keycap off and shoot some air in and around the cap first. It might be a dust/debris-caused issue.
2. If it doesn't help, try to factory reset your keyboard by holding Fn + Z + J for 4 seconds.
3. It might be a switch problem. Gateron switches on your keyboard are soldered. If you are interested and have confidence in changing switches by soldering, Keychron can provide switch replacements. Here is a video about soldering: Soldering Guide Video.
4. You can also test the defective keys here: Keychron Key Test. Shoot a video of the defective keys without keycaps on. Keychron's tech team can check it out and assist you with your problem.

Bluetooth Latency and Input Lag

The Bluetooth latency is designed to be 30 milliseconds, though actual performance may vary with real-world usage. If you experience input lag, please try the following steps:

1. Try to factory reset your keyboard by holding Fn + Z + J for 4 seconds.
2. For wired mode, please replug the data cable or change another data cable/port on your device.
3. For Bluetooth mode, check for interference from nearby Bluetooth devices, and try testing the connection with your smartphone.
4. If you are a desktop user, ensure your motherboard's Bluetooth antenna is installed. If your PC requires a Bluetooth adapter, please install one.

Can't Type After Waking Up Mac?

This issue is caused by Apple's FileVault, which prevents third-party Bluetooth keyboards from unlocking the login screen.

Solutions:

• Turn off FileVault to enable normal login.
• Use a wired connection to enter your password.

Keychron keyboards support FileVault login in wired mode only.
