For the units I am wanting the all lights off command for they do share the
same house code. There are also (for various reasons) appliances on the
same
code that I do not want to turn off.

It ought to be trivial even without the source code since somewhere the
button is sending 0001 and I just want to change it to send 1101. It might
require some disassembly to locate the exact sequence that needs changing
but this should be quite trivial. Custom chips would prevent this obviously
which is why I asked what people knew before breaking the MT. I was hoping
for readable chip that I could hex edit then write over the original or
replace with an appropriate PIC. Wish I knew more about electronics then I
could roll my own. Oh well, back to the drawing board I guess :)
