The top of the door pull is held by a spring clip. I'm unsure of the best way to remove it but you could try a steady pressure while leaning it from side to side.
Sounds good! I use one of those fork-shaped tools (Powerbuilt brand) with the angled head designed to get in behind both sides of a trim clip and pry it out without damage. Recently I bought a pair of special pliers designed to squeeze and pry Christmas-tree clips. Haven't needed those yet - different fasteners demand different techniques, but you can never have too many tools.a used feeler gage is an excellent tool to prise out escutcheons and trim finishers. I use the 1/20" thickness as it's thick enough to work with and flexible enough to give when the part is too stubborn. for other trim parts I use a plastic spatula. Silly alfa thoughts...
