Hello Avocece
The LMP is NOT attached to the keyboard during the pairing process since you have to turn the thing upside down to press the small black button on the underside of the keyboard during the pairing process. On my LMP, there are 2 buttons on the Right hand edge of the keyboard. A big round silver one that you can use to turn the iMac keyboard (not the LMP keyboard) on and off, and a very small diameter round black button which is the one that controls the On Off state of the LMP keyboard.
OK, so now we have that out of the way, you should be able to connect quite readily via the above instructions.
Cheers
John
