Radio turns on, but no sound, locked


Unfortunately if you're radio's locked you have to take it to a GM dealership to have it unlocked - they have a 1-800 number they can call to get an unlock code, but the call has to come from a dealership rep with a valid dealer code.

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.

Unlock radio for a 1996 monta carlo?


hi friend,
Your car has a anti theft radio in it . What has happened is at one time some one entered a code into the radio. What you are going to need to do is stop at your GM dealer and have them unlock the radio. The charge will be approx 30$ (that's what my dealer charges) Make sure you specify that you want the old code removed. Also ask them for the four digit backup code they get when they call GM. They will press numbers 2 and 3 on your radio and get digits then they will press am fm button and get two more digits and with those digits they will call a 1-800 number that only GM can call and they will get the unlock code. Sorry but I cannot divulge the number. Big TROUBLE!!! Hope I have helped
UNLOCK Code is:
1761
Ignition ON
Hold Minutes for first numbers
Hold Hours for last numbers
Press AM/FM Button
Turn ON Radio

hope this helps u

My car radio aking for a code


If an audio unit with theft protection is disconnected from electrical power, you must enter a unique code number into the unit or it will not work. This code and the audio unit’s serial number are listed on the anti-theft ID card that comes with the vehicle (some people say that they find it on a sticker in the glove compartment, but I wouldn't count on that). If this card is lost, you must obtain the audio unit serial number in order to get the radio code. Some newer vehicles allow you to retrieve the audio unit serial number electronically from the radio. Refer to your owner’s manual for the specific procedure (the following usually will work: Turn the radio off. Push the preset 1, preset 6, and power buttons at the same time, then quickly release. The code will come up to two sets of numbers)
Once you have the audio unit serial number, you can call Auto Customer Service at (800) 999-1009 or have the dealer look up the radio code.

Need an unlock code for 1997 camaro


First you need to get a number code from the radio. Hit the number 2 and 3 preset buttons at the same time, after 5-10 second a 2 or 3 digit number will appear. Write down then hit the am/fm button for the 2nd half of the number. Once you have it call GM, 1-800-537-5140, when prompted hit 102107*, the automated voice will ask for the code previously gotten for the radio . (ie; 123456*) It will then give the 3 or 4 digit unlock code. Note this is for Delco radios on Chevrolets. I'm guessing there is a different prompt for radios on other GM divisions.
