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

Bluetooth PIN

Hi James,

There are several factors that can contribute to the you're facing with pairing a Bluetooth device to your computer. This could be caused by a recent update or missing update components. For us to resolve your concern, kindly answer the questions below:

• Have you tried to connect other Bluetooth devices to your computer and see if the same issue will occur?
• The prompt asking you to enter the pin, what is the exact message?

As a initial recommendation, you can attempt use these default pins located below:

• 0000
• 1111
• 1234

Take note that theses are the common default pins when there is none provided with your device or you do not have a way to check.

We look forward to your response to our queries.

 

Clear "Pin suggested" list in People Bar

Does anybody know how to clear the "Pin suggested" list on the "People bar"?

Contacts are added to the "Pin suggested" list once you've pinned and unpinned them. But there seems to be no obvious way to remove them from that list.

After playing around with this feature and pinning and unpinning many dummy contacts, it's rather annoying to see them in the "Pin suggested" list when you click on the "My People" icon in the taskbar.
