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."

When i try to turn my radio on it says loc hoow do i unlock it?


Does your GM car or truck Radio display LOC and does not turn on? Chevrolet, Buick, Pontiac, GMC, Cadillac, Oldsmobile vehicles used a theft system to lock the radio when power is lost. This system was used from the ealy 1990's to the early 2000's.

Instructions:
  1. If your radio displays the word LOC, you can retrieve a set of factory numbers in the radio that enable you to get a backup unlock code. If the radio says INOP, you will have to leave the key in the "ON" position, or let the car run for at least 1 hour before you attempt any unlock procedure. INOP means a secondary theft lock due to too many false attempts to unlock the radio.
  2. Looking at the face of your GM Delco radio, hold down the preset buttons 1 & 4 OR 2 & 3 (Depending on year and model) for approximately 10 seconds or until a set of 2 or 3 numbers comes up on the display. Write the numbers down.
  3. Next press the AM / FM button. A new set of 3 numbers will now show. Write these numbers down. You will then need to call a 1-800 phone number with these numbers to get the unlock code. There are many sites on the internet that can get it for you- for a small fee. Or, try calling your local GM Dealer and ask for them to do it. Many times they will do it for free. It only takes a minute.
  4. Once you have the unlock code, enter it by pressing the MIN button until the display shows the last 2 digits of the unlock code, then press the HR button until the first 2 numbers or shown. Then press the AM / FM button to enter the code. The radio will now display SEC, and normal function is restored.
Also, its possible that you need RESET your GM Radio; this is the procedure: While performing maintenance on your car, you may disconnect the radio from the battery in your GM vehicle. GM cars contain Delco radios that are protected by Theftlock, which locks the radio after it has been disconnected from a power source. Iit can only be reset and unlocked with a car-specific security code. Identifying the security code for your GM vehicle is the only way to reset the car radio and disable the Theftlock protection device.

Instructions:
  1. Turn on your car. Your Delco radio will show "LOC" in the LED display.
  2. Press and hold down both the second and third preset buttons. Hold these buttons down for at least six seconds.
  3. Write down the two- or three-digit code that appears in the LED display.
  4. Press the AM/FM button on the radio.
  5. Write down the next two- or three-digit code that appears in the LED display. You should be left with either a four- or six-digit number. Turn off your car.
  6. Call the Delco radio automated customer support line at 1-800-537-5140.
  7. Press "1" and then press the pound sign. The automated voice should respond "Invalid code, try again."
  8. Enter the number 139010 into your phone and then press the "*" sign.
  9. Enter the four- or six-digit number you wrote down from Steps 3 and 5, and then press the "*" button.
  10. Write down the four-digit code given by the automated voice.
  11. Turn on your car. Enter the Delco unlock code using the procedure outlined by your GM owner's manual. Normally, the unlock code is entered with the "HR" and "MN" buttons on your radio.
  12. Press the AM/FM button. If you have entered the code correctly, your LED display will read "SEC" and the radio will be unlocked.
