The switch is very easy to remove and replace with same or you can do what I and a few others did - replace with surface mount buttons on the front cover (search my posts)
Essentially, use a needle tip iron and desolder the two pads under the switch at the outside edge of the PCB while gently pulling up on the switch. Then desolder the 3 other switch pins. Go slow and apply just enough heat to melt the solder.
Look at my PDF in the files section of alternat input buttons.
