99 S-10 radio unlock code

[61_FL_Apache]

I just bought a 99 S-10 for my daughter and the radio is locked. The PO said he replaced the battery and the radio locked.

How do I get a code to unlock it? I have seen other posts where the stealership will charge $50-60 to do it.

Thanks for the help!!

call chevy home office if it was a factory code if it isn't and the po set the code no way to get it without taking ti to the dealer to reprogram the cd player

Is that my only option? I dont think the PO set it because he said he didnt remember having one.

We charge like 40-80 bux for it at the dealership I work in. On yours I think all u gotta do is go in it with a scanner and select "setup radio" and it will set it up and unlock it. U may scan threw the owners manual, the original unlock code may be in it.

No owners manual with the truck. I think I will replace the head unit with something better and save the money.

Thanks for the input guys!

I just found this and will try tomorrow.

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.

Ok I got it going and here is what worked for me.

I got the codes from step 1 above.

Called the 1-800 number and used dealership code 106010.

They gave me my 4 digit code (1261)

You enter the code by using the HR and MIN button until the code is reached on the display.

Press the AM/FM button until SEC is on the screen.

Turn on the radio.
