The "a" on my keyboard was getting flakey. It took a couple times of hitting it to work, and I was really getting annoyed. Also after almost 2 years of using this HTC (Branded the 8125) by Cingular, I was itching to disassemble it.

I could not find any information on repairing the keyboard/key cleaning.

There is a manual for this in the ftp space should anyone need. It is not specifically for the Wizard. You have to prise the lower housing off in a similar fashion. The rest of the disassembly is easy enough. Soon, you will have the 'middle' section of the phone in your hands, with only the keyboard and its flex connector attached.

Look carefully for screws, tabs, clips, anything that is holding the keyboard into the piece. You won't find one. Look even closer, and you still won't. I had my glasses off (contacts out) and focus at about 2" and still didn't see a damn thing holding the keyboard assembly into the part.

That is because there isn't anything.

I apologise for not taking pictures, it was together before I remembered. But here is the issue:
If you look at the bottom of the panel that holds the assembly, where the softkey buttons are, there are slots that allow you to see the layers of the keyboard. Using a very fine x-acto blade or knife, slide just under the black layer, and pry up. The keys and their laminated components are glued down to the flexible board that has the key contacts. The 'domed' part of the contacts is part of the key layer, and will be the bottom. A bit of cleaning and the contacts were again happy and shiny.

Make sure that when you put the key layer back down that it is centered properly. Make sure that the soft keys at the top are not bound, or they will stick up and catch the slider.

Oh, and the kicker? None of the other disassembly was needed, since there was nothing inside the phone to release the keyboard. But what the Hell, it needed a good cleaning anyway.

One more thing, the best place to do this is NOT in a hotel room with almost no tools. That makes it far more challenging. :)
