Replaced Battery

[doridori]

I have a 2002 Porsche Boxster and I just replaced the battery.

Couple of questions:

1. Now, the stereo is asking for the 4 digit code. Since I bought the car used and the previous owner never gave me this info, how can I obtain the 4 digit code for the stereo?

2. The car needs to do a California Smog Check soon, do I need to do a drive cycle before the smog check? If so, where I can find the details of the drive cycle?

Thanks
