Windows 10: Can't connect my Microsoft Bluetooth Designer Keyboard after replacing battery

I replaced a battery and now I am unable to connect my Microsoft Designer Keyboard to the computer. My Surface Pro 3 finds the keyboard and tries to pair asking for a passkey to be entered on the keyboard followed by the enter key. But I keep receiving the message Try connecting your device again

Connecting Microsoft Bluetooth Designer Keyboard

Hi,



Thank you for writing to Microsoft community forums.



You can Connect a Bluetooth device in Windows where the connectivity between your Microsoft Bluetooth device and your computer depends on your Bluetooth transceiver or in-built Bluetooth:
Connecting a Microsoft Bluetooth® device.



As you mentioned that you are not able connect your Bluetooth keyboard to your computer, I would suggest you to follow the steps mentioned in the articles:

Connecting Microsoft Bluetooth Designer Keyboard

After replacing the batteries in my Microsoft Designer Keyboard I am unable to connect to my computer. I have tried connecting to my wife's HP Pavilion and I am using a Surface Pro 3. I press and held the pair button until the esc key blinks white and tried
going through the bluetooth pairing steps. My surface finds the keyboard and attempts to pair and asks for a passkey to be entered on the keyboard followed by the enter key. Each attempt I get the message "Try connecting your device again." I called support
four times and each time my call was dropped when they said they would transfer me to the correct person. Two reps asked for my number and one asked for my email but neither called me back after disconnecting the call. I have reset the keyboard, restarted
my computer, and installed all updates. The driver is no where to be found on Microsoft's page but the mouse is.

Why will the keyboard not pair to my computer?

 

Can pair new Microsoft Designer Bluetooth keyboard - but not connect

Hi

I just bought a new Microsoft Designer Bluetooth desktop keyboard to use with my Dell XPS 15 9530.

I'm running Windows 10 and I'm able to pair the keyboard by going to settings and adding and adding a new bluetooth device. It prompts me to type in the passkey on the keyboard and press enter.

After doing so, the device is added to the device list and after (very briefly) being listed as "Connected" it switches to be listed as "Paired".

In this state, the keyboard doesn't respond to any input - even after power cycling it. The keyboard even keeps blinking in the Esc-key as if it's still ready to pair.

I've reset the Bluetooth adapter, run the troubleshooter and made sure that all of my drivers are up to date. Nothing helps.

Any good suggestions?
