I have the Izzo 3000 golf gps, it has screws on the back which came out fine. The battery was soldered in, using a solder iron I took it out and then soldered in the now battery I purchased from eBay. As for your Sky Caddie, I'm sure a sharp blade of some kind can be wedged into it somewhere making it pop open. Have you checked You-Tube for a video that might show you how, good luck.
