Hello Everyone,
This is how I solved this issue on my DELL running windows 10.
Connect to the Keyboard as usual and when it prompts you to type a PIN, type a random one using a normal keyboard (not wireless). I used "1234".
Now here comes the truth. After you click "connect", W10 keeps on trying connecting to the keyboard but does not tell you what you should do, so I tell you:
Type the same PIN you entered before on your wireless keyboard and then press enter.
I tryed this a couple of time and always worked for me.
Hope this helps.
OMG, IT REALLY WORKS..
DO IT THE SAME WAY IT'S QUOTED ABOVE, AND IT WILL START WORKING..
TO MY AMAZEMENT, I TRIED 0000, ALSO TRIED 8'0,,,,,,, WITH NO LUCK, UNTIL I TRIED '1111' PRESSED CONNECT FROM A WIRED KEYBOARD, AND WHILE THE PC WAS TRYING TO PAIR, I PUT IN '1111' ON THE BLUETOOTH KEYBOARD THEN 'ENTER'. AND TO MY SURPRISE, IT WORKED.. AMAZINGLY.
THANK YOU VERY MUCH FOR GUIDING ME TO THIS PROCEDURE, I ALMOST GAVE UP TRYING, BUT ITS GOT TO BE DONE A FEW TIMES, IT WILL WORK I ASSURE YOU. GREAT..
