How do you overide the theftlock system on a GM car stereo My father passed away I replaced the battery and dont know the code. Tried a couple guesses and it went from LOC to UnOP code Help?

Answer 1

First thing check the owners manual that came with the car. Most people write the code in the book. If this doesn't help call or go to the dealership, bring the registration card or title with you. If the radio is factory they will be able to get you the security code.

Hopefully this helps. JQ

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 did get the 6 digit code by pressing the 2 and 3 presets and then the am/FM and getting the last three digits. I have a 2002 Chevrolet silverado and dialed the 800 number and pressed 1 for Chevy and then entered 206010 that is printed aboveand hit #, but I get error in message saying wrong code. I can't even get to enter the code I have wrote down. Does anyone know the six digit code for Chevrolet so I can get my stereo to work?

Thank you,
