I have heard of using canned air to blow the solder out and crystallize it, but I don't think I would try this. I use a heat gun and pair of IC tweezers. Whatever you do, add some solder paste so it reflows first. Ideally you should use a tip for the PLCC that concentrates the heat on the legs of the chip and doesn't overheat the chip itself. Take a look at the temp ratings of the chip if you use the heatgun approach. Most chips are only rated to take that kind of heat a little longer than it takes to reflow the solder.

Maybe the programmer will make contact anyway with the cover open, haven't tried it so I don't know.
