Go to a GM dealer If you show them your registration and prove you are the owner they can look up your radio code

    Don't take the car to them. go in and explain that you need the radio code. You will need to prove ownership. If they still want to charge you try to negotiate. You may be able tocall the manufacturer directly or reach them online.

How can I enter radio code?


Use the radio station preset buttons to enter the code after you turn on the power to the radio. The radio's display may say "CODE" asking for the security code.

Tip

DISCONNECTING YOUR BATTERY without losing the RADIO CODE


I constantly read frequent requests for RADIO CODES referring to the disconnection of battery power ( whether its for changing the battery, etc.) and the radio is now INOP. Here is a simple way to save radio codes, radio stations, clock time and computer settings. Purchase from an auto parts dealer, a 9 volt battery powered lighter socket connector. Plug into lighter, do your battery work, After work is completed, disconnect, and radio will work as before. Unit will cost less than 20.00 and well worth it.

Radio locked no code


Unlocking the Delco Radio Theft-Deterrent Feature After a Power Loss

If you know the code that was used to lock the radio then use the following instructions from the owner's manual to unlock the radio.
Quote:
Enter your secret code as follows; pause no more than 15 seconds between steps:
1. Turn the ignition on. LOC will appear on the display.
2. Press MIN and 000 will appear on the display.
3. Press MIN again until the last two digits agree with your code.
4. Press HR until the first one or two digits agree with your code.
5. Press AM-FM after you have confirmed that the code matches your secret code. The display will show SEC, indicating the radio is now operable and secure.

If you enter the wrong code eight times, INOP will appear on the display. You will have to wait an hour with the ignition on before you can try again. When you try again, you will only have three more chances (eight tries per chance) to enter the correct code before INOP appears.
If you don't know the code that was used to lock the radio then you will have to use the dealer's unlock procedure as follows. The dealer code changes over time - the one listed is current as of this posting. If it doesn't work try 08359 or search the forum for messages with a more recent code.
Quote:
1. Press and hold presets 2 & 3 for about 10 seconds until the first three digits of the display code are displayed.
2. Write the numbers down.
3. Press the AM-FM button, write down the next three numbers.
4. Call 1-800-537-5140. When asked, enter dealer code 202108, press the * button, and enter the six 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 two numbers, press the MIN button and set the next two numbers, then press the AM-FM button. The display will show SEC, indicating the radio is now operable and secure.

To remove the code, repeat step 5. you should see --- on the radio face indicating the code is now out of the radio."

I have a locked radio for a 2000 pontiac grand prix thanks to a battery exchange...can anyone help ...the 6 dig code is 292298


Hello! You have done half of the work already! You can take the code, and the VIN to your vehicle; and call your local GM dealership. Tell them that you need the unlock code for the radio, and they will ask you for that information.

Also - there are 2 modes to the TheftLock - "LOC" or "SEC" and "INOP". Once the anti-theft is activated, the radio display will show "LOC" or "SEC" - you then have 8 attempts to enter your code. If after 8 attempts you don't enter the correct code, the display will change to "INOP". It is only at this time that you will need to wait one hour, with the ignition ON; before you can retry. After that - you will have only 3 attempts before the radio enters "INOP" mode again.

Hope this helps and good luck!

You can drive to the dealer and have them help you enter the code since they are alway's connecting and disconnecting battery's, The instructions are in the manual and the codes might be written in the front or back page. If no codes were programed try 0000 and see if that works. IF the dealer wants to charge you a crazy amount, you can get your codes here on www.radio-code.com Good luck and hope this helps.

Radio problem


InOP - Too many wrong code attempts have been entered and the radio must be left powered on for one hour with the battery and ignition applied before three more attempts can be made. Entering only the correct code will unlock the car radio. here's your answer . cheers
