Delco Stereo Question "Please Help"

I bought a 1996 grand Am Se V6 3100 motor for my daughter off family, it has 65,000 miles on it. I had all the gaskets from the head up. + the water pump done. The car runs great. But this is her first car and I'm now into it for about $2300 and The battery was disconnected and the AC-Delco premium stereo system display says <LOC> with the anti theft light flashing. The prev. owner has passed, and had not logged a code in the car manuel. Is their anything I can do to reset this code? to get the stereo working. Thanks in advance...

Welcome to AF.

Thier is nothing that can realy be done other then take it to a dealer.
They "might" be able to unlock it, but you probly have a paper wieght now .

You can also just try guessing, 0000, 1234, 5678, etc etc.
Someone may have used something very easy so they didnt forget.

Good Luck
