You should have a code to unlock the radio in the manual that came with your car if you do not you will have to contact a dealer to obtain it.

Radio displays locked


You may need the owners manual for this. The dealer can provide the steps too.
If the display says LOCKED you have to unlock it before it will accept the code. On some models you turn the radio off, press the number 6 or the select button, then turn the radio back on. Once the display is all lines or dots, you can input the code by pressing the number one button for the first digit and so on.

2000 saturn radio is locked. how do i unlock


1.) To begin, if your radio is displays LOC, then proceed to step 2. If your radio says INOP, then turn your ignition to the RUN position, and turn the radio ON. You must leave it like this for a minimum of 1 hour (not 59 minutes) to clear the INOP message. I would wait 1 1/2 hours just in case doing it too early causes the timer to start over.

2.) Turn your ignition to RUN (if not already), and your radio to OFF. Press and hold preset buttons 2 and 3 for around 5-10 seconds to obtain a scrambled version of your radio's original factory set code.


3.) Call a GM dealer with this code. Tell them you are with a local shop i.e. I am Joe with Good Year Highway Tire; Then tell them: We have a 2000 Saturn SL we just changed a battery in and the radio is now locked. My mechanic pulled the pre-code. Could you give me the code? This usally works at no charge.

Once you have the code write it down. Keep atleast 2 copies. Hope this helps!

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.

My stereo in my blazer is locked need a code to unlock it


There is no code in this year Blazer radio. The radio has the VIN encoded in it and when you turn on ignition the BCM (Body Computer Module) compares it's VIN to that of the radio and if they don't match, the radio is locked out.

Radio is unlocked through the GM Tech 2 scan tool. Dealers will do this for an outrageous fee ($40 - $100+) for just a few minutes time.
