Once the cable is detached, the housing is mostly free. You will need to pull it away from the door handle bar though. This is a metal bar coming from the outside handle which slots into the mechanism. To get it out, just twist the top of the actuator away from it and it should slide out easily.

You will also need to pop the inside lock bar off the green clip that it's attached to. This can be done by inserting a flathead screwdriver in between them and turning it sideways.
