I tried using the project and it works fine. but all it does is asks for the 5 digit code, then the master code and new code. it does not glow the led or seem to send an unlock signal on any pin.

thanks for having this prototype posted here.. i just want to ask something.. are the two capacitors near the crystal oscillator 33uF or 33pF??.. if those are 33pF, then there is no available electrolytic capacitor with such rating.. the schematic symbol of those two represents an electrolytic one.. are those capacitors electrolytic or ceramic?? thanks again!
