keyboard
I have charged this keyboard for an hour and turned it on, and it still won't show up on the bluetooth to pair it to the iPad I’m using, when I turn the magic keyboard on the light lights up green then flashes blue then it stops, I don’t know what that means,
Also, I don’t know what the button above the power button is for. This keyboard doesn't have a place to change batteries cause it stuck on a fabric that the keyboard doesn't come off, so it's like a book.
Resetting the SMC should be able to fix the issue. Note that this will reboot the MacBook, so you will lose any unsaved work.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
That's actually a feature, albeit a very poorly documented one.
The Apple Wireless Keyboard refuses attempts to be overtaken by a different host without a deliberate disconnect, physical access by the user, a very long timeout or a manual reset.
Your keyboard model is that of "October 2009", the manual can be found here: https://manuals.info.apple.com/MANUALS/1000/MA1208/en_US/Apple_Wireless_Keyboard_2009_UG.pdf
Page 6 states that you should disconnect (not unpair) your keyboard before connecting (or pairing) it to another computer.
Once the keyboard is no longer in a 'connected' state, it will happily reconnect to any device it has previously been paired to.
So in order to resolve your problem, you should either take your keyboard back to the computer it believes to be connected to (and explicitly disconnect it there) or try the following in order to disconnect it manually:
In case you release the power button too early, i.e. without fully establishing a connection, the keyboard will simply fall back into the mode it was before – still connected to the other computer, safe from being overtaken. :)

The Magic Keyboard has rechargeable batteries that cannot be replaced by the user. If you're running low on batteries, plugin a lightning cable to recharge the batteries.
You pair it with the iPad by first turning it on (move the slider on the back from the off-position to the green on-position). Then on the iPad open
Settings > Bluetooth. Ensure that Bluetooth is enabled, and wait for the Magic Keyboard to appear in the list of devices below. Tap it to pair.If the keyboard does not pair, you might have it paired to another iPad or computer that is nearby. Ensure that you're a good distance from any such device before pairing - or turn those devices off before pairing with your iPad.
