It's an anti-theft measure. The stereo is locked with a 4 digit code.
If you enter the correct code, it will unlock. The dealer can look up
the unlock code based on the serial number or something.

I believe you use the tune and seek buttons to enter the digits.

Before I changed my battery, I purposefully set the unlock code
myself, because I wasn't sure what the default is, and didn't want to
be locked out of the Stereo. Then, I disconnected the battery, put in
the new one, and unlocked the stereo with the code I just set. It
worked good.

In your case, I think you can try guessing the numbers. How much free
time do you have? You could also guess an easy sequence, like 1234.
maybe the previous owner had to change the battery too, and set the
code to something easy.
