99 ML 320 with machine gun lock on front passenger door. I have the new actuator in hand but I'm having trouble removing the old one because I can't figure out how to remove the lock cylinder. There are plenty of write-ups on how to R&R the actuator, but I can't find any detail on removing the lock cylinder other than what is quoted below.

To expose the screw, the rubber plug in the door panel needs to be removed and the lock actuator rotated counter clock-wise about 3-5 turns. Don't go too far or the screw will come out and then you have trouble. The rubber plug is in the face of the panel opposite from where the key inserts the door. Loosen the 4mm screw and pull / wiggle out the lock tumbler. The tumbler will just pull out with some effort.

There's even a MB factory video on youtube showing how to do it. Unfortunately, the vid is 23 seconds long and provides no detail. I tried doing what the lab coat guy does so effortlessly in the vid, but no luck in removing the cylinder.

My main problem is I can't see what I'm trying to unscrew. My eyes aren't good and I can't focus if I peer through the approx .25" access hole for the allen wrench. Anyone have a picture of the lock cylinder out of the door so I can see what I'm trying to loosen?
