radio locked out

    I have a 2000 SL2 that I bought used. I recently had to do some work which
    required disconnecting the battery. Apparently, there is some sort of
    anti-theft stuff that requires entering a code to get the radio to work.
    All the radio says is LOCK. The manual says to go to the dealer. There has
    to be another way.

    Any ideas?

  2. 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.

    Sorry to say, you must go to the dealer on this one unless you get lucky
    entering the number sequence.
    If I remember correctly, you should be able to do some button sequence which
    will display a number that if given to Saturn will yield an unlock code.

    Google gives these options:

    Here is what I have found out so far. On my particular radio, once it got
    locked, depress keys 1 and 2 at the same time. After a few seconds, a 4
    digit code pops up. Saturn calls some magic number and gives them this
    code, then they get the real code back from the magic people. Then
    supposedly, if you do the keys 1 and 2 again and get the 4 digit code, it
    should be changed to the code that Saturn gave me. The only thing is, the
    service guy told me the key has to be in the run position, not motor
    running, and radio off, for an hour for this to work. I came home and am
    waiting because I didn't want to hang out there for an hour. We shall see.

    Seems to me that they should be able to determine the proper code from the
    model and serial numbers on the radio (requires removing the radio from the
    dash) or from the VIN if this is the original radio.

    I post this mainly because when it happens again, I will have something to
    refer to, suffer from CRS if you know what I mean.

    Again, on the 2000 SL2 (not sure what else this might apply to), once you
    get LOCK with the radio turned on, turn it off and depress keys 1 and 2 at
    the same time. You get some 4 digit code. This is what Saturn has to call
    in to the secret place and get you the real code. I tried all the internet
    stuff about calling some 8YY number, but was never successful. Anyway, once
    the real code is obtained from Saturn (or however you do it), turn the radio
    on with the key in the run position and the radio displaying LOCK. The
    radio must be on and LOCK must be displayed. Leave it like this for an
    hour, then you will get the ----, then you can enter the code that Saturn
    gave you. It worked fine on my vehicle.
