You need to enter the unlock code for the radio. This should be in the user manual just inside the front cover.

The radio has code "LOC" on the screen, won't respond to anything I try.

The LOC stands for locked
You will need a code to get this radio to operate.
You will need to have the code entered at any GM dealership & have proof of ownership with your ID
It is a theft deterrent system installed on all radios these days since the 90's

My daughters 97 saturn was worked on and now the stereo says LOC and wont play anything got any suggestions?

Hi, my name is Ben. When LOC is displayed on the radio it indicates that power has been shut off to the radio. Probably disconnected the battery during servicing the vehicle. Once this happens, there is a code which must be entered using the buttons on the radio to make the radio able to work again. If you don't know the code, you will need to take the vehicle to a dealership service department and have them unlock the radio. Sorry, I can't help you more, but hopefully you have the information you need now. If you can find the code, sometimes it's written in the owner's manual, I can give you the procedure for entering it into the radio.

After reconnecting battery radio will not work. LOC appears on screen. power switch has no effect . how do i fix?

Hello.... LOC means that a customer code has been stored into the radio for security reasons. At this point the only code that can be retrieved is the backup code. This code can be retrieved by the dealer. From this code they can get the customer code. If this is not a option may I recommend getting a new radio....

Good Luck
