Question about 1999 Chevrolet Cavalier

2 Answers

Need help unlocking my RADIO!

My GM radio in my 1999 Chevy Cavalier z24, is locked (from where we replaced the battery) I went through and got a code of 5704. But when I went to enter the 4 digit code on the radio, I found out the numbers on the radio just go up to 1999. Am I doing something wrong? Is there a trick? or did I get the wrong code?

    When you say the "#1" key, the "#2" key are you talking about the buttons usually used for programming stations? Just want to clarify. The instructions I did have, say to use the "min" button and another button (I am not able to check for sure the other button, but wanting to say its hr, stuck indoors for a bit)

1. By the #1 key you will set up the first safe code digit. For "5" you need to press the #1 key 5 times.
2. By the #2 key you will set up the second safe code digit. For "7" you need to press the #2 key 7 times.
3. By the #3 key you will set up the third safe code digit. For "0" you need to press the #3 key 10 times.
4. By the #4 key you will set up the four-th safe code digit. For "4" you need to press the #4 key 4 times.

    Yes, of course, the "#1" key, the "#2" key are the buttons usually used for programming stations!

Reset code to unlock my radio will get you your radio unlock code for $5.00.
Contact a GM dealer, preferably the selling dealer. They may have the code stored in their computer system if they sold the car. Otherwise you are probably going to have to remove the radio and get the Serial # off the radio. With this serial # the GM dealer will provide the code.

Locked radio

You have to go to a chevy dealership to have them unlock the radio. They use a special code that will unlock the radio and then allows you to pick a new code. Hope this helps.

I have a 1997 Chevy cavalier Radio LOC. I changed the battery this morning now the radio is LOC. Can you help?

My dealer wants $85 for the code. Another dealer - 2 hrs away - wants $50. This looks more like a GM money-maker than a security feature.

My radio is locked i just need the code for a monte carlo 97 GM delco radio

If the code is not at the back of your manual, try 0000 and if the radio locked it self from taking any more codes. Just disconnect the battery and that will reset the radio so you can re-enter the code. If 0000 did not work then log on to, you can get your cod there for like $12.00 which is cheaper then the dealer and you get to know the codes as most dealer will just unlock the radio. Good luck and hope this helps, keep me posted if you have any more question.
