Step 5 Free the keyboard
 I recommend to use the iFixit Opening Picks for this step! Otherwise you could scratch/damage the keyboard or frame by metal on metal Place it between the keyboard and the frame. I started near the on/off button to make a opening.Just go around the whole keyboard with the opening picks, slide it through every side of the keyboard, except for the under side (there are no clips there).Just free all the clips, you should hear some pops. Do not pull the keyboard out, just free it from the clips which are holding the keyboard. The clips that are holding the keyboard are pretty strong, so you need a little force to free it. 
Step 6 Remove the keyboard
 After it's freed from all the clips, you can turn the keyboard towards your self, but hold the keyboard with one hand!Do not remove the keyboard as it's still connected with some ribbon cables! The ribbon cables can rip easil 
Do not pull the cables yet. The ribbon cables are still connected to the ZIF connectors, pulling the cables without opening the ZIF connectors could break them!Now open up the ZIF connector and pull on the blue tab to remove the cable.

Step 7 Disconnect the ribbon cables
 Open up the ZIF connector with your nail or plastic opening tool, but be careful as they can break easily! 
Hold the blue tab on the keyboard cable. 
And pull on the blue tab to remove the cable from the ZIF connector straight out the socket 
 Add a commenStep 8 Remove the ribbon cable
 Open up the ZIF connector carefully.Hold on the blue tab.Remove the cable straight out the socket.Step 9 Remove last ribbon cable
 Repeat the process for this ribbon cable as well.This cable is still holding to the frame with lightly adhesive on two places, just pull on it Carefully to remove it from the frame.

Step 10 Remove the keyboard
 2nd place which has lightly adhesive on it.After it's freed now, you can successfully remove the keyboard! 
 Step 11 Set-up new keyboard 
If you going to replace it for a new keyboard, it's possible that you need to transfer one cable from the old keyboard to the new one. Do the same process as earlier to transfer it.Some models only have 2 connectors on the keyboards and/or motherboards, this is because it's simply missing the black light feature

 Step 12 Connect the keyboard again

  CONCLUSION
