Yup, it's a fairly easy DIY job. The rope method, plastic sticks or dowel rods sanded flat on one end work well. Even the nylon tire levers from a bicycle shop work well. Lube with dish soap or Go-Jo. Then, go easy. DO NOT FORCE anything. If something doesn't go smoothly back off and work a different angle. The bad news is even working very carefully a piece of glass occasionally gets broken. The good news is that if you are careful and gentle the odds are greatly in your favor.
