I have a pioneer remote control unit CU0FD002 for Pioneer Hi-Fi equipment. The equipment was purchased in the early 1990s. The sleep function recently stopped working. I believe it has to do with the rubber membrane you wrote about in this article. My problem is opening the remote's case. The knife trick you suggest doesn't work, and it may be that the remote's clamshell is glued together. Do you have a suggestion as to how to open such a remote?


The chances are that it is glued together or possibly welded at various points around the perimeter. Make sure you've removed all the screws (some could be hidden under labels). A credit card is also useful for prying into the gap between the halves and would do less damage to the plastic than a knife. If you can separate the halves even a bit, you might be able to see where the snap clips are and push in and upwards to release them. Another possibility is to heat the edges of the control with a hair drier. Most glues soften with heat, so it may help to free the halves. Other than that your only option is to cut the control using a junior hacksaw or maybe a toothed cutting disk and Dremel rotary tool.
