All GM stereos since about 96 have a theftlock stereo. They either use a
4 digit code to lock/unlock them or they communicate with the ECM and
use part of the VIN code to ID the vehicle. On the first type ANY power
interruption can lock the radio. On the second type as long as the radio
is in the correct vehicle it shouldn't cause a problem. You don't need a
scanner to repair the first one you just push the buttons and get the
codes (as the OP already did) then you call that in to GM (dealers can
call it in easily) and then they will be given the unlock code. Punch
that code in and the radio is ready to go. On the second type the only
time you will need a dealer is if you install a different GM stereo with
the wrong VIN code in it. Then you need a dealer AND proof that the
radio was legally purchased, they can then use a programmer to change
the VIN code in the radio to match your vehicle.
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
