Problem with Magic Mouse pairing

[horace528]

Hello Apple Support Communities
I have used a Magic Mouse for some time, maybe now an year. But I started having this problem today.
When the Magic Mouse did not connect with my MBP, I removed the mouse from the Bluetooth and tried to put it back.
But the Bluetooth Setup Assistant is saying that the pairing did not work, and asked for a passcode or a different pairing method.
Here's a screenshot:

Also, I tried using the System Prefrences and click on mouse to set up my Magic Mouse, but it said the same thing; pairing failed.
Here's a screenshot:

Is there any solutions to this problem? I hope that you can get me an answer fast, as I use Magic Mouse a lot with my MBP.🙁🙁
Screenshots will also be attached.

Have you tried installing a fresh set of AA batteries? How about turning off and back on Bluetooth on the Mac? Anything nearby that could be causing interference?
