Reverse design this Keyless Entry

[tonyp12]

This is a good keyless design,
Programmerble pin code with reset switch if forgoten.

**broken link removed**

Pin Code:
comes preset with a default code of "159" plus "*" or "#" key
Solonoid is engaged for 5 seconds.

To change the Code:
Press the Reset Switch until the Yellow Light on the Front Control Panel lights up. Now you can input your new Code (1 to 8 characters) into the Front Control Panel, followed by either the “*” or “#” Key.
Will beep twice to confirm that the Code has been changed.

Important: If it beeps three times, then the Code has not been accepted, and you must repreat the steps above.


To Change the Batteries: If the Red Light and the Green Light are both lit at the same time, it is time to change the Batteries.

Yeah sure.. ok I get right on that... Why don't you go find something better to do.

Not complete reverse design, but some with with PCB software
can redraw the traces and drill holes etc.

I can look at components and reply with values.

But if the DIP chip has to be programmed, when it's not so easy.

maybe this is a touch kinder way to say it. you can replicate the board all you want but the code in the chip will be a lot harder to get to. so, you really are wasting your time...

Here is a scan of the PCB

I'm wating a reply from the Manufacture of the chip
to see if they all leave the factory pre-flashed.

P.S just got an email from the makers of this board.
I can order them (even just a few) for $12.96 each.
but 6 weeks from China

hey, this is out of one of those little electric safe's isnt it??
how come you want to reverse design it?? whats your intended project?

Hey Tony12. I am stuck with the same keyless circuit (battery came off). Do you have pin layout of this chip? Thx a bunch
