GM DELCO THEFTLOCK RADIO 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 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 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 screen. 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 GM 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 the radio in my 2001 chevy cavalier and it is throwing a LOCKED code. How do I get a code to unlock it?


You need to pull the radio back out and get some numbers off of it and call the dealer. Or just take the radio by the deal parts department.They will tell you what the code is you need to punch in.

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 this morning would not work, a code of -


They cannot do this over the phone./and won't..they dont know you or if anything is stolen.
Procedure..
Stop at a chevy dealer or any GM dealer,they can retrieve a backup code out of the radio..by pushing some buttons.
Then they call in to the delco center using the backup code and obtain a new unlock code.
They can enter the code to unlock the radio.
If by chance a code has been entered incorrectly 3 or more times,then they will have to let the car sit with the key in the on postion for an hour before entering new codes.

My 2004 cavalier stereo is locked.i put a


That's the anti theft lock... It's not a system that comes with every car radio, but i've saw a few of those on cavaliers and sunfires, and a few civics, and i think a couple others have some too, but i've only personnally seen and worked with the ones i mentioned. In any case, unfortunetly even if i know how they work, there is no easy way to get them unlocked and working again. You need the special code for that specific radio, and to get it you don't have the choice to go to you GM dealer and ask them to do it. You need their special machines to get the codes and get the radio unlocked, there is no other way other than changing it for an aftermarket radio again like before. So if you really want to get the OEM radio going again, go with the car to your GM dealer to prove to them it's not stolen and they will get the codes from the GM support center with their dealer code and will unlock your radio, but of course they will charge for it, dealers never give any gifts to anyone.:p So ask them how much they charge for the service, cause in some cases, buying an aftermarket radio will cost less.

Unlock antitheft code for 2004 chevy impala


Radios in the 2004 Impalas are tied to the vehicle's VIN through the computer, so it may be somewhat difficult to get the code. However, the following steps should work:

1. Press and hold the buttons for presets 1 & 4 (may be 2 & 3). The word "SEC" should show.
2. Press the "MIN" button. "000" should be displayed.
3. Press the "MIN" button again to have the second two numbers appear. Record these numbers.
4. Press the "HR" button for the first two numbers to appear. Record these numbers. -- Note: Your number sequence should be the numbers from the "HR" button followed by the numbers from the "MIN" button.
5. Call 1-800-537-5140. This will get you to the GM unlock code automated line. Ignore the prompt and enter "202108#". Next enter your code (remember, HR then MIN) followed by the * key. For example, 1234*. A 3 or 4 digit code will be given to you. If you get a code such as 0532, drop the zero when entering it into your radio.
6. Enter the code into the radio IAW the applicable manual.
