what about a plunger?just pop it out dude, go to the 99 cent store, buy one of those suction cup guns and with the ammo, rub a very thin layer of super glue on it and stick it on for like 10 seconds to let the glue dry and pull up gently. put some goo gone or carb cleaner on it and clean off the surface and your done.
