I'm thinking of doing a slight mod to the stock stereo this summer but I'm concerned that I didn't get the security code from the previous owner. I remembered that I've disconnected the battery before for several weeks and never needed to re enter any codes before. Do I really need to find out what the codes are for the stock stereo, and if so where could I obtain that info other than the dealer?

This is a link I found a while ago that shows how to get the codes for a locked radio. Maybe this will help you?

Thanks for this information but I have to wonder if it'* true and whether it works.


Here is a way to get the unlock code. The numbers after the 800 number
are dealer codes and may not be valid any longer.


1. Press and hold presets 2 & 3 for about 10 seconds until the first 3
digits of the display code are displayed.


2. Write the numbers down.


3. Press the AM/FM button, write down the next 3 numbers.


4. Call 1-800-537-5140, when asked, enter 202107,or 19-281, or 219055,
press the # button and enter the 6 digit code from the radio, you will
get an
unlock code, write it down.


5. Go back to the car, press the HR button and set the first 2 numbers,
then
press minute button and set the next two last numbers, press AM FM
button,
SEC should be displayed, turn on radio.


To remove customers code, repeat step 5. you should see --- on radio
face,
the code is now out of the radio.


Setting a code.
Hold down 1 & 4 until --- appears then use the hr and min buttons to set
a number
between 0000-1999 then press am/fm, it will say rep then you reenter the
code again
hit am/fm again it should say sec meaning secure and then when ever the
key is off the
radio has a little blinking red led to warn possible thieves

Worked for me. I just used it to unlock my radio after I forgot the code. On step 4 I had to enter a different number to get to the pontiac motor division. But it works great.

When you say you just used it, do you mean within the last week? Was there any charge for anything?

I just did it 5 minutes ago.


1) Dial 800 #
2) Press 219055 #
3) Enter in the 6 digit code from the radio


There is no charge.

I have a 91 pontiac boneeville SSe and the below didn't work for me !

1. Press and hold presets 2 & 3 for about 10 seconds until the first 3
digits of the display code are displayed.


2. Write the numbers down.


3. Press the AM/FM button, write down the next 3 numbers.


4. Call 1-800-***-****, when asked, enter ------,or 19-281, or 219055,
press the # button and enter the 6 digit code from the radio, you will
get an
unlock code, write it down.
