Question

How can i unlock my radio code alarm for a 1998 Chevy Cavilaire?

Answer 1

The code for your radio is a personal code selected and programed  by a previous owner. It will be a four digit number between 0000 and 1999. To enter the code, use the HR and MIN buttons, then press AM/FM. If SEC is displayed, the code was correct and the radio can then be turned on. If LOC is displayed, the code was incorrect. You will have a limited number wrong entries, in most cases 3, before the radio goes into SAFE mode and will not accept more entries for a period of time.

To find an unknown code, press and hold buttons 2 and 3 until three numbers show on the display. Write them down. Then press AM/FM and three more numbers will show. Write them down.

With these six numbers a GM dealer can call to get the security code.

First you need the Theftlock code up to 4 digits, and then it is necessary to follow the owner's manual instructions.  If you don't have one, borrow one and with GM's permission (you know what I mean) can photocopy a page.  If your code is still not on a rectangular sticker inside the dashboard glove box and you don't know it, seriously you have MORE than one thousand options to try in order, with patience, from 0, or 0000 to 9999.  Think about it, even a code number 1, could 1, 01, 001, or 0001!  So, I hope you know the code and are just trying to find the method - you didn't say?
