ML320 Door Lock Cylinder

I'm trying to replace my driver side door lock assembly, but I can get the door lock out. How do I remove the door Lock?

Remove small plug just above the door latch. then insert a long (i think 4mm) t-handled allen into hole to remove screw on the back side of the door lock cylinder. Remove lock cylinder and slide the door handle off. Remove the phillips screw and the retainer that is inside the door will come off. Continue to remove latch assembly.
