Step 6Finding which pins works for our keys
Then, you will have to find which two pins on the keyboard microcontroller are the ones to be pressed together to close the circuit and send the key code to the computer, so:
1) Take the upper plastic layer (it's glued to the bottom layer, you can use a Xacto knife to cut the small glue spot that puts the 2 layers together.
2) Put one of the multimeter probes at the brown spot, and then put the other probe in the first of the circuit track endings
3) Get the resistance reading in the multimeter (the one with the OHM symbol on it) , if you don't get any reading, move the probe to the next pin in the track endings, until you got some reading.
If you don't have a multimeter don't worry, just follow the track until the ends, just don't get lost because of the tiny lines =P
Once you find where the key ends, do the same procedure for the bottom layer of the keyboard, you need to find the track ending for the Ctrl, Alt and Right and Left arrows.
Make some drawings to remember which pin is for which key.
