Hello Everyone,
I have found that it is possible to disassemble an Apple wired keyboard by using a hair dryer on "low heat". Note: DO NOT USE a heat gun, it will simply damage your keyboard beyond repair. However, a hair dry is acceptable if use at low heat. Just direct the heated air on the white bottom cover of your Apple keyboard for up to 4 or 5 minutes. The key is to allow the bottom cover of the keyboard to get hot enough to soften the double sided adhesive film. Once it is heated, the keyboard will easily pry apart. I had to use this method as a means to fixed my damaged cord. So yes it is very possible to repair an Apple wired keyboard. However on a scale of 1 to 10 where 10 is the easiest measure of difficulty. I would rate it an 8.
