If you have trouble unsnapping things and you can get to the tabs, drip a touch of oil in there. Also, prying them apart with a screw driver is tempting, but often they break. I use a thing called a "spudger". People that fix cell phones and tablets use them to pop things apart. They are made of a hard plastic, and you can buy a dozen real cheap on Ebay. Anyone who works on their own scooter should have them.
