While this may look relatively easy, I can assure you that it is easy to screw up as well. Having swapped out key pads for friends, it is very easy to miss-align those pads and keys, thus having to repeat the process more than once. Additionally, most of the musicians I've come across in my lifetime have absolutely no electro-mechanical abilities and need to call an electrician to change a light bulb. All of those tiny plugs are very easily damaged when plugging and unplugging them from circuit boards, especially if you do not have the right tool for the job. A small, metal screw driver is not the proper tool.

Good luck,
