Windows 10: Bluetooth not generating PIN when connecting keyboard

Windows 10, current and updated, Microsoft keyboard Elite for Bluetooth model1002. Worked just fine until a couple of weeks ago when I had to replace batteries. When attempting to reconnect, Windows asks for a PIN to connect the keyboard. Used to generate a PIN for me to enter on the keyboard. Cannot connect keyboard without PIN.


Tried some of the "goofy" solutions of trying a second (wired) keyboard to enter the PIN, and re-enter on my wireless keyboard, but no joy.


Please advise...

Windows 10 not giving PIN to connect Dell bluetooth keyboard


Windows 10 Pro.
Intel Bluetooth on Lenovo ideapad Y500.

The keyboard was originally connected without issues. Nephew changed batteries and tried to go through re-connection (even though he didn't need to). Now every time we go to connect it finds the keyboard but asks to enter the pin. He originally told me that it did give him a pin (6 digit?) but he ignored it.
No bluetooth keyboard is present in the list of devices. Bluetooth mouse works fine. We have tried 0000, 1234 and 123456. I think it's still looking for the code it originally gave. Uninstalled bluetooth from device manager, rebooted and let it reinstall. Still asks for pin without giving a new one. I need to find a way to reset it so it gives another PIN.

Trying to diagnose over phone and slooooooow join me session. World is ending because nephew can't play games. *Wink

No Pin Generated to add Bluetooth Keyboard

Using Windows 10. Under Settings> Devices> Bluetooth & other devices> I set the keyboard to connect and clicked "+ Add Bluetooth or other device (and confirmed that the Bluetooth software switch just below was toggled to On. A PIN is not presented.
All I see in the Add a device window is "Bluetooth 3.0 Wireless Keyboard (CR) Connecting (CR) Enter the PIN for Bluetooth 3.0 Wireless Keyboard." (CR) and the box in which to enter the PIN. However, no PIN is presented.

All updates have been installed.

Bluetooth Keyboard PIN

These solutions were already readily available in other documentation and did not work. As I stated before "it appears that I need to wipe out the Win10 device's previous association with the BT keyboard so that I
can start the pairing process again, but I cannot find any documentation on how to do that."

The device is NOT currently listed as a under "Bluetooth & other devices", so it can't be removed. However, despite not being listed under Bluetooth & other devices, the devices is being treated by my phone as if it is already paired and is simply asking
for the existing PIN.

There is no default PIN for this device. As I noted before, when I connected to an Android device, it generated a PIN. I also attempted to connect the device to my Win10 laptop and it also generated PIN number (see attached image).

The problem is that I have previously attempted to pair my Win10 mobile device and the pairing process timed out before I was able to enter the PIN. So it now appears that it is expecting me to type in a PIN that my Win10 phone previously briefly gave me,
but for which I do not remember and had no means to record.
