    I might possibly have a bad alternator, but that's another issue. I got an OBDII scanner/reader tool and while my check engine light comes on, the only code it reads is "Incorrect Immobilizer Key". I have read that this can happen if the battery is unplugged for too long (which mine was, as it was dead and then I left it charging at AutoZone.
    I am using the original fob key - is it safe to use the tool to clear the code with the original key in the ignition, or will this lock me out of the PCM?
