I could not locate the code on any of the spots listed in various forums on the web. I think it's easier on the Gen 1s, but if you don't find it....
I found a thread where someone had written out the list of possible codes in an order where they would not be repeated. You can punch them in (grab a beer and park in the shade) and eventually you'll get the code. I recommend going through the code reset procedure first or you may just find a "User code" rather than the default code. It took me about 25 minutes to unlock mine. I then programmed a code I could remember.
If you can't find what I'm talking about, comment here and I'll try to find it again.
