Bluetooth keyboard not being discovered

Found this, it worked

Finally I found a good idea online. I am documenting it here so that if I ever have this problem again, I will remember the steps that I had to take to repair. I have tried this with both the Android phone, and the MacBook Pro, and it seemed to work with both.

1. Turn on Bluetooth (if it isn't already turned on).
2. Begin scanning for devices.

   In Mac OSX, click on the little Bluetooth icon at the top of the screen. Click "Setup Bluetooth Device...".

3. After the computer or phone begins scanning, press and hold the power button on the wireless keyboard. This is important. When I tried pressing button first, then scan, nothing happened. You have start the scan first, then press and hold the button.
4. At some point the green light usually starts flashing (although not always. weird).
5. After a few seconds, it will (finally) notice the keyboard. You may have to click on the keyboard to tell it to pair.
6. It will ask you to type a few numbers to verify the pair. At this point you can release the power button.
7. Type in the requested numbers.
8. The pairing should complete.
