Basically.
The one thing to make sure is to get it in there the right way around.
The original reply was to me and that's the only thing to really be

I put the card on an ESD mat and then using a scribe(or small standard jeweler screwdriver) I begin lifting the corner marked with the dot . Once I feel it move a little I go to the diagonal corner and lift up. Once this corner starts to come up, the crystal is loose enough to remove with my fingers. Go slow and watch not to scratch the conformal coating of the PCB.
