Below worked for me just two days ago... you DO NOT NEED to take it to the dealer and you do NOT need to disconnect the battery, this can all be done with a couple clicks on your radio and call into a phone number.
This was posted previously on another post...
Procedure:
01. Turn the ignition ON (The radio displays LOC)
02. Hold down the Radio Presets 2 and 3 buttons for six seconds
03. The radio display changes from LOC to a three-digit number. Write this number down. Don’t take forever, fifteen seconds max before the next step.
04. Press the AM/FM button
05. The radio display changes to another three-digit number. Write this number to the right of the first one.
06. You now have a six-digit number, the first three digits are from STEP 03 and the last three digits are from STEP 05
07. Call 1 800 537 5140
08. Press 1 then #. You’ll hear Invalid Code, try again
09. Press 139010 then #. You will be asked to enter your four or six digit code followed by *
10. Enter the number from STEP 6 then *
11. Listen to the four-digit number and write it down. It will be repeated twice
12. Turn the ignition ON (The radio displays LOC)
13. Use the MN and HR buttons to enter the code from STEP 11
14. Press the AM/FM button. The radio display changes to SEC
Your radio is now un-locked and usable

    Your instructions are identical to others I have found on the net, but it will not work for me. My radio doesn't say LOC, it says LOCKED. I've tried unplugging the radio and starting over, still won't give me the 3 digit number in step 2

Here is how to unlock Delco Theftlock radio that displays "LOC"

Taken from:
http://autoforumz.com/Pontiac-Help-u...pict40505.html

GM DELCO THEFTLOCK RADIOgm Delphi radio code - icon1.png UNLOCK CODE:
1. Press and hold presets 2 and 3 for about 5 to 10 seconds until you
get 3 digits on your display. This is the first 3 of 6 digits you will
need, so write 'em down.
2. After doing step one and writing down the code, immediately press
the
AM/FM button to get the last 3 of the 6 numbers you'll need, and write
'em down. (if you wait too long between steps 1 and 2 and the LOC code
displays again, just start over).
3. Call this number, it's a prerecorded messageicon1.png, so don't worry about
having to talk to anyone...1-800-537-5140. The voiceicon1.png will ask if
you're
calling for Chevy, Pontiac, Cadillac, etc... When you here him tell
you
to press "2" for Pontiac, press 206010 and hit the # key. He'll ask
you
for the 6 digit code that you've written down. Enter that and press
the
* key. He will then give you a code, and the option to get additional
4
digit codes, but one should be sufficient.
4. Follow the normal procedure in your owners manual for unlocking the
radio with your new code...press the hour set button on your radio
until
you get the first two numbers of the code, then press the minute set
button until you've entered the last two numbers. Immediately press
the
AM/FM button once the correct code is entered and the code SEC or
"secured" will be displayed on the display scregm Delphi radio code - icon1.pngicon1.png. Now, just turn the
radio on, and your ready to roll.
There is an additional step you can take to remove all codes from the
radio and start from scratch by entering your own personalized 4 digit
code so that it won't get you in a pickle again! Just repeat step 4
and
you should get a display screen that reads ---. This means the code is
out, and you can now program your own code. Of course, once you
receive
the 4 digit code from the GMicon1.png recorded message, just keep it in a safe
place, because you can use that same code again and again should you
have any more problems with it in the future. Good luck, and yes, it
does work.

I replaced my gm delco radio and now it displays


The dealer should not charge you to do this. Call around and ask what they can do for you. The security system on these cd units is to keep people from stealing them and putting them in their car like you did ( minus the stealing part ) The radio needs to be reprogrammed to match your vin code. I would just suggest that you call around see what happens.

Bought a new cd player for my 2004 malibu maxx,


You will have to have the radio programmed to the vehicle (they have to do a service program to store the VIN in the new radio and configure the features to your vehicle..) it is a security feature. plus the 04 malibu maxx uses the GM LAN data com. and your radio is also your driver's information center.

CAR STEREO NOT WORKING


Hi
With the newer cars most radios have a theft deterrent device built into the radio, and if they steal your system it will not work in another jeep/car the dealer knows the unlock code, some charge to unlock the radio some don't.
That's why when doing electrical work on a car/truck etc. You have to have 12V DC power to the battery terminals all the time or you will loose the code and then only the dealer can help you unlock the radio.
HTH.

Bose delco cd radio for 97 pontiac


I don't know your experise when it comes to repair. This problem is normally a bad laser or spindle motor. You can clean the laser and spray a Cleaner/Lubricant into the openings on the bottom of the spindle motor. This is a common problem I see with this stereo when it comes to repair.

Delco unlock code and procedure


This is the process for the CD deck. I assume it's the same for any 88-90 deck with the DelcoLok system. It may also work with 90+ DelcoLok I units.

1. Press and hold presets 2 and 3 for about 5 to 10 seconds until you
get 3 digits on your display. This is the first 3 of 6 digits you will
need, so write 'em down. (mine were 881)

2. After doing step one and writing down the code, immediately press the
AM/FM button to get the last 3 of the 6 numbers you'll need, and write
'em down. (if you wait too long between steps 1 and 2 and the LOC code
displays again, just start over). (mine were 322)

3. Call this number, it's a prerecorded message, so don't worry about
having to talk to anyone...1-800-537-5140. The voice will ask if you're
calling for Chevy, Pontiac, Cadillac, etc... When you hear this,
press 1 for chevy, followed by 02107and hit the * key. (i.e. 102107*) He'll ask you for the 6 digit code that you've written down.(mine was 881 322) Enter that and press the * key. He will then give you a code,(mine was 810 891)

4. To unlock the radio:

A. Turn the ignition on.
B. Press "SET" (000 appears on display).
C. Press "SEEK until the first digit of the code appears.

D. Press "TUNE" until the second and third digits
E. Press "AM-FM" (000 appears on display).
F. Press "SEEK" until the fourth digit of the code appears.
G. Press "TUNE" until the fifth and sixth digits of the code appear.
H. Press "AM-FM". Now the radio can be turned on.

see that help you good luck!!!!

Radio unlock code


Press & hold the 2 & 3 buttons @ the same time for about 10 seconds; a 2 or 3 digit code will appear, write this # down,press & hold the am/fm button for about 10 seconds: another code will appear, write this # down, then call 1-800-537-5140 and enter 202108 followed by the * key, then enter the #'s that you wrote down from your radio followed by the * key. The call will give you a 3 or 4 digit override code. Write this code # down so you have it if you ever need it again. Enter this # into your radio following the instructions in your owners manual. If you get an override code that starts with 0, you drop the 0 when entering the code into your radio.
If you don't have an owners manual, try this, press & hold the hour button until the first 2 digits of your code come up, then press & hold the minute button until the last 2 digits show. Then press the am/fm button. This should reset your stereo.
if nothing happens you should leave your car running for 1 hour.
