Using the Ipod Opening Tool pull up on both sides of the rectangular module while keeping the rest of the calculator flat on a surface face down You may get a lot of resistance from the module. Do not use too much force as you risk damage. Use small amounts of force to work the module out.

Now pull up on the back cover of the calculator while holding the rest of it flat on a surface. Be careful not to tilt the front of the calculator at this point. The keyboard buttons are now unsupported and will fall out of place.

Some models might require removing the two battery screws before the back cover can be pulled up. These screws are somewhat smaller than the others but can easily be removed with the same screwdriver.
