NOTE: This button assortment will help repair a few failing buttons in most devices that use rubber contact switches. However, because there are countless different devices and endless possible keypad designs, no universal kit can solve every problem with every keypad. These repair pads are meant to be used by technicians and experienced do-it-yourself-ers. To know for sure these will work you should open your device and inspect the keypad for design and size. If there is anything between the rubber keypad and circuit board contact such as a white film, LED strip, clear plastic light pipe, etc.. these things could cause problems that a universal button may not be able to solve. That does not mean the product is not as described or does not work. [25 Button Kit] Permanently fix buttons in most devices that use rubber keypads. Tested over 1 million button presses!
