How do you take the trunk lock cylinder out?




I am trying to take the trunk lock tumbler cylinder out with no success. I am following WIS by rotating the key 45° and pushing on anything that shows in the hole but nothing moves. A youtube procedure shows it on a handle assembly that has the cylinder being inside a metal housing while mine is in a black plastic housing (see pics). Anybody knows how to remove the cylinder?
Thank you,
Radu




I swapped my whole rear hatch...trying to think...I
guess I just swapped the whole handle assembly...don't recall switching the cylinders..
