The radio is locked on a 1995 oldsmobile 88


How to Unlock a Chevy Radio Step 1: Start the vehicle and turn on the radio.
Step 2: Press and hold preset numbers 2 and 3 until a three digit code appears on the radio display. Write this code down.
Step 3: Press the AM/FM button. Your radio will display a second three digit code. Write the second code down. You will now have a six digit code.
Step 4: Call the Chevy Radio Code phone line at 1-800-537-5140.
Step 4: Enter 106010 followed by the # key to direct you to the radio code retrieval system.
Step 5: Enter the six digit code you retrieved in steps 2 and 3 followed by the * key. They must be in order. You will be given a four digit radio code. Write down the radio code.
Step 6: Start your vehicle and turn on the radio. Using the Minute and Hour buttons, enter in the four digit radio code to your stereo system. Press the AM/FM button to unlock your stereo.
How to Unlock a GM Radio Step 1: Start the vehicle and turn on the radio. The radio will display "LOC" indicating the Theftlock system is activated.
Step 2: Press and hold preset buttons 1 and 4 for ten seconds. (If you don't have a fourth preset button, press and hold presets 2 and 3.) The radio will display a three digit number. Write this number down.
Step 3: Press the AM/FM button. Your radio will display a second three digit code. Write the second code down. You will now have a six digit code.
Step 4: Contact your local GM Dealer and give them the six digit code. They will give you a four digit radio code.
Many dealers will give you your radio code for free, while others may charge a small fee. If your dealer is charging a larger fee, consider calling another dealer or doing a Google search for sites offering GMC Radio codes. They usually charge a small (around $10) fee.
Step 5: Start your vehicle and turn on the radio. Press the Hour button on the radio until the first two number of the code appear. Next, press the Minute button until the last two numbers of the code are displayed. Once all four digits appear, press the AM/FM button to unlock your stereo. The display will read "SEC" indicating you have successfully unlocked your radio and it is fully operational.
If radio display reads "INOP" while the vehicle is on, too many incorrect radio codes have been entered. To remove "INOP" from your display and unlock your radio, you must leave the key in the On position for one hour. Once you've retrieved your radio unlock code, write it down for future use. Your radio code will not change and having it handy will save from going from the radio code retrieval process again.

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.

How do I put in a radio lock code for a 98 Pontiac Grand Prix?


The radio comes with a preassigned lock code that must be obtained from Pontiac. They will need you to follow these steps to retrieve two sets of numbers for them to call GM and obtain the assign lock code for your radio. STEP ONE: Press number 2 and number 3 simultaneously. Hold until the first set of numbers appear. Then press the AM/FM button on the radio for the last set of numbers to appear. Give those numbers to Pontiac, and they will call for the radio lock code. They will also provide you the steps to enter that code to unlock your radio.

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.
