In the following guide I explain how to disassemble a MacBook Pro 15″ (Mid 2010) in order to remove and replace the keyboard.
In my case something sticky was spilled on the keyboard and it stopped working completely. In fact, the laptop didn’t even start with the damaged keyboard connected to the motherboard.
I confirmed that this is just a failed keyboard by turning it on using the power-on pads.
The keyboard is attached to the internal side of the top cover assembly. In order to remove and replace the keyboard the entire MacBook Pro (MBP) has to be disassembled.
