Now that they physical keyboard is removed, we can focus on the ribbon cable

Caution, this step can make or break the connection point, so be gentle

Gently flip the black hatch part of the connection point upwards

Remove the ribbon cable from the connection point

When re-installing the cable, be sure that it is inserted all the way, and that the hatch is closed. If not, it may malfunction, or not work at all, and you will have to do this all over again
