Fix Bluetooth Keyboard PIN Errors When Pairing on Windows

Quick Overview: Troubleshooting PIN Errors on Windows Bluetooth Keyboards

Pairing a Bluetooth keyboard on Windows should be straightforward, but a known bug in Windows 8, 10, and 11 sometimes causes PIN errors or makes the passcode window disappear too quickly. Fortunately, there are reliable fixes.

• Check setup first: Update your Bluetooth drivers and disable power-saving settings to prevent connection drops.
• Option 1: If Windows generates a 9-digit code that vanishes, restart pairing and type the code on the Goldtouch keyboard immediately before pressing Enter.
• Option 2 (best method): Create your own 4-digit PIN using your laptop or USB keyboard, then quickly enter the same PIN on the Goldtouch Bluetooth keyboard to complete pairing.
• Confirm success: The keyboard LED stops flashing and the Windows key opens the Start menu once connected.

By following these steps, most users can fix pairing issues in just a few minutes and enjoy a stable connection going forward.

Introduction to Fixing Windows Bluetooth PIN Errors

If your Windows 8, 10, or 11 system is prompting you for a PIN code during Bluetooth pairing (or the code disappears before you can enter it) you’re likely running into a known Windows bug.

Normally, Windows should generate a 9-digit passcode automatically during Bluetooth keyboard pairing. When it doesn’t, it can appear as if the keyboard is unresponsive or stuck.

This guide walks you through the two most reliable workarounds, along with the basic setup steps to help ensure a successful connection. Most users can resolve this in a few minutes by following the process below.

First, Check These Bluetooth Setup Requirements

Before pairing fixes, it’s important to confirm that your Bluetooth setup is configured properly. Outdated drivers or power management settings can interfere with device pairing, and in some cases, users aren’t even sure whether their system has Bluetooth at all. If that’s the case, here’s how to check if your computer has Bluetooth.

1. Check Your Bluetooth Drivers

Make sure your Bluetooth radio drivers are current. Windows Update often does not provide the most up-to-date drivers for OEM systems like Dell, HP, or Lenovo, so we recommend downloading them directly from the manufacturer’s website. If you’re using an external adapter, make sure it’s compatible — our USB Bluetooth Dongle guide can help. For a broader rundown on diagnosing Bluetooth issues, see Microsoft’s official guide.

To check your current drivers:

• Open Device Manager (Search for “Device Manager” in the Start menu).
• Expand the Bluetooth
• You should see one of the following:

For systems with a Bluetooth dongle: “Generic Bluetooth Radio” and “Microsoft Bluetooth Enumerator.”

For systems with built-in Bluetooth: A branded radio (like Intel or Broadcom) and “Microsoft Bluetooth Enumerator.”

If you’re not sure which drivers are best for your system, you can send us the make and model (like ThinkPad T540, HP Elitebook 840 G3, Dell Latitude 6540), and we’ll help you find the right ones.

Once installed, restart your system before moving to the next step.

2. Disable Power Saving on the Bluetooth Radio

To prevent Windows from turning off your Bluetooth adapter to save power:

• Go to Device Manager.
• Under Bluetooth, double-click your radio (e.g., Intel Wireless Bluetooth).
• Go to the Power Management
• Uncheck the box: “Allow the computer to turn off this device to save power.” If you’re still having connectivity problems, check out our article on stopping Bluetooth interference for more solutions.
• Click OK. Consult this guide for more on disabling Bluetooth power-saving settings.

Note: If you don’t see the Power Management tab, it may be disabled in your system BIOS. This is common in some laptops.

What to Do When Windows Prompts for a PIN or Doesn’t Generate One

When Windows behaves correctly, it automatically generates a PIN or passcode during pairing (either a 4-digit PIN or a 9-digit passcode. Unfortunately, this doesn’t always happen due to a Bluetooth stack bug in Windows 8, 10, and 11. Below are two proven workarounds. You only need to try one of these) but if the first doesn’t work, the second usually does.

Option 1 (If Windows shows a passcode but the window closes too quickly):

1. Begin the Bluetooth pairing process for your Goldtouch keyboard.
2. If Windows briefly displays a 9-digit passcode but the dialog closes before you can enter it, restart the pairing process.
3. When the code appears again, immediately begin typing it on the Goldtouch Bluetooth keyboard and press Enter.
4. If the window closes again before you can type the code, repeat the process. Timing is key, and this can take a few attempts.

This method works for some users, but due to the finicky nature of the bug, Option 2 is generally more reliable, especially if you’re using a laptop with a built-in keyboard.

Option 2 (Recommended, Works in Most Cases)

This workaround bypasses the auto-generated PIN entirely by letting you create your own 4-digit PIN during pairing.

Before starting, have either a built-in laptop keyboard or an external USB keyboard available (this is required for entering the first part of the PIN).

Step-by-step:

1. Begin the Bluetooth pairing process for your Goldtouch keyboard (GTP-0044W or similar).
2. When Windows prompts you to enter a PIN or passcode:

On your laptop keyboard or USB keyboard, type a 4-digit PIN of your choice (e.g., 4321), then press Enter or click Connect.

1. Quickly switch to the Goldtouch Bluetooth keyboard and type the same 4-digit PIN, followed by Enter.
2. If the pairing is successful, Windows will install the appropriate drivers and the keyboard will be connected.

If the pairing fails, try the process again. Timing matters! If too much time passes between entering the PIN on the first keyboard and repeating it on the Goldtouch keyboard, the pairing will not complete.

Once connected:

• The blinking blue LED on your keyboard will stop flashing.
• Pressing the Windows key on your Goldtouch keyboard should open the Start menu, confirming that it’s paired and functioning.

Summary and Support

This Windows Bluetooth pairing issue is unfortunately a known bug across multiple versions of the operating system, and it affects many Bluetooth devices beyond Goldtouch. The good news is that one of the two methods above usually resolves it completely.

Once the keyboard is paired successfully using Option 2, it should continue reconnecting automatically in the future without further issues. If you’re looking to improve your typing comfort as well, explore our full range of ergonomic keyboards.
