Felch,
I tested the code this afternoon, looks like that's not working, i use JDM PIC programmer with icpro105D to program the chip (PIC12f629). i put 1K resistor between pin 6 and +5V, also, measured the both input (data0, 1) and output (pin7) with oscilloscope, there are no signal from pin7 when i put the proxkey on HID reader (having beep sound from reader), i don't know is it the wiegand format problem?
I have experience on writing code for ATC89c51 and some AVR, but not PIC, can you post your combo lock project or do the code modification for me?
Thanx in advance.

William
