I have the same MacBook. My battery Model No. is "A1280" Hope this helps.

Simply lay the key in the correct direction on the keyboard (Don't put it upside down; Upside down letters on a keyboard aren't fun) Once the key is just laying in its socket, simply press the key down, as if you were typing.

There is a connector which connects the home button to a power source at the bottom of the phone. When the screws are taken out, the home button is disconnected from that power source (probably due to the screen raising a little) and the home button no longer works.
