I removed my standard KA stereo with a nice CD player without any special keys. What you need is two long thin pieces of wire or metal. I used two small screwdrivers. Your stereo will have four holes in it, two near the top and two near the bottom. Forget the top ones, push the screwdrivers or pieces of coat hanger or whatever into the bottom holes. It will take a while but you shouild feel the little clip on each side of the stereo. Squeeze the clips towards each other and kinda pull towards you. It took me a few goes, but I managed and it only took like 10 minutes.
Hope this helps
