Time for the project mentioned in post #1.
This is to reproduce the plug-in keypad controller that was available as an accessory with this radio, and others in the Lowe line. I was able to find a very similar key switchpad and case to the original, and also was able to track down the all important IC required. I have an original keypad that belongs to my other Lowe radio, so was able to measure dimensions and get the correct appearance. Service data includes the schematic for the keypad, and it would also be possible to reverse engineer from the example I have. It was also possible to use that pad to make sure the radio's control input still works before getting started.
I'll document here, with pictures. 1x keypad, 1 IC two transistors and a diode, plus a few resistors and caps. Not too hard I hope

I don't hold with furniture that talks.
