2001 Car lost power and required jump start. Radio in "LOC" mode. Need radio serial number, unlock code and procedure to unlock and restore radio function.

Step 1: Look at your radio. Check and see if the code "RDS" is written on the face of the radio. If "RDS" is present, contact a GM dealership to have your radio unlocked by them.
Step 2: Check for the identification code. Press buttons 2 and 3 for 8-10 seconds. If a code does not appear on the display, you won't be able to unlock your radio in this manner.
[If that doesn't work vvv]
In order to obtain your radio unlock code, you need to find your radio's serial number. You can get the radio serial number directly from your radio.
Step 1: Turn on the ignition. Turn the key to "accessory" mode or "on" mode.
Step 2: Turn on the radio. Press the power button to turn on the radio.
If your radio displays any functions such as playing a CD, cassette, or a radio station, your radio is not locked. If no sound is heard, you may need to replace your radio unit.
If your radio is locked, "LOC" is displayed on the screen.
If "INOP" is displayed, keep your ignition on for 60 minutes with "INOP" on the display. After the hour is up, it should change to "LOC." After this you can proceed with the next step.
Step 3: Write down the code. Press buttons 2 and 3 at the same time and hold for 8-10 seconds. Write down the three-digit code that is displayed.
Step 4: Note down the code. Immediately press the AM/FM button. Another three-digit code is displayed. Write it down as well.
This is your six-digit radio serial number.

Now that you have your radio's serial number, you can obtain the radio unlock code from General Motors. Be ready with a pen and paper to write down your radio unlock code.
Step 1: Contact the GM radio hotline. From any landline or cell phone, call the toll-free GM Radio hotline at 1(800) 537-5140.
Step 2: Enter the code. When it requests a code, enter "106010" on the keypad, followed by the pound (#) sign.
Step 3: Enter the radio serial number. You will be prompted to enter the radio serial number you have just obtained.
At the prompt, enter the number followed by the pound sign.
Step 4: Write down the radio unlock code. The prompt will read out your four-digit radio unlock code. Write it down precisely.

Now that you've obtained your Chevrolet radio unlock code, you need to enter it into your radio.
Step 1: Switch on the radio. Turn your ignition on and press the radio power button. Your radio will display "LOC."
Step 2: Enter the first two digits of the radio unlock code. Press the hour button on the radio to enter the first two numbers of your radio unlock code.
Continue pressing the button repeatedly until the first two digits of the radio unlock code are displayed.
Step 3: Enter the last two digits of the unlock code. Press the minute button until the last two numbers of the radio unlock code are displayed.
Repeatedly press until they match the two digits you need.
Step 4: Confirm the code. When the code matches, press the AM/FM button. "SEC" will display on the radio, indicating a successful attempt to enter your radio code.
If you enter the code incorrectly eight times, the display will switch from "LOC" to "INOP." You'll need to leave the ignition on for an hour as described in Part 2 before you can retry.
Write the radio unlock code in a safe place such as in your owner's manual for future use.
Most car dealers will charge you a lot of money just to get the code for you. If you follow the right steps, you can get the code for free and be able to start listening to the radio again in just a few minutes!

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.

Hope this help (remember comment and rated this).

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.

this did not work it says code 139010 is invalid to I cant get past step 8 or 9 my number from step 3 is 702 and step 5 is 706 someone please help Im going crazy

Hi

Thanks for using FixYa. If you fail to enter the correct code eight (8) times, the radio goes into INOP mode. You have to wait an hour with the ignition on before the radio returns to LOC mode (go for a long drive somewhere).

After that the the radio will go to LOC mode, then follow this procedure to unlock it—

To unlock the car radio - Have a pen and paper ready. Push and hold stereo preset buttons 2 and 3 simultaneously for several seconds. Three digits will appear in the display "XXX", write them down. Push the AM/FM button, three more digits will appear in display "YYY", write them down.

Press 1 then # (pound). You’ll hear “Invalid Code, try again”

Press 139010 then # (pound). You will be asked to enter your four or six digit code followed by * (start)

Enter the six didgit number obtained from above procedure.

Listen to the four-digit number and write it down. It will be repeated twice

Turn the ignition ON (The radio displays LOC)

Use the MN and HR buttons to enter the $ digit code that you have heard.

Press the AM/FM button. The radio display changes to SEC. Your radio is now “un-locked” and usable. The Theft-Deterrent feature is STILL active! If you want to disable it, use the instruction in Owner’s manual.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

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.

Good Day,

The following procedure will give you a new code that you can use instead of your personal code. Using this new code, you can “unlock” your radio and then “re-lock” it with a new code if you wish. Prerequisites: The radio must be in LOC mode NOT in INOP mode. Let me explain. If you have activated the Theft-Deterrent feature of your radio and loose power, the radio goes into LOC (theftlock) mode. With the ignition on, you must use the MN and HR buttons to enter you personal code in order to unlock it (The instructions are on page 3-27 in your Owner’s manual). If you fail to enter the correct code eight (8) times, the radio goes into INOP mode. You have to wait an hour with the ignition on before the radio returns to LOC mode (go for a long drive somewhere).

Procedure:

01. Turn the ignition ON (The radio displays LOC)

02. Hold down the Radio Presets 2 and 3 buttons for six seconds

03. The radio display changes from LOC to a three-digit number. Write this number down. Don’t take forever, fifteen seconds max before the next step.

04. Press the AM/FM button

05. The radio display changes to another three-digit number. Write this number to the right of the first one.

06. You now have a six-digit number, the first three digits are from STEP 03 and the last three digits are form STEP 05

07. Call 1 800 537 5140 08. Press 1 then # (pound). You’ll hear “Invalid Code, try again”

09. Press 139010 then # (pound). You will be asked to enter your four or six digit code followed by * (start)

10. Enter the number from STEP 6 then * (star)

11. Listen to the four-digit number and write it down. It will be repeated twice

12. Turn the ignition ON (The radio displays LOC)

13. Use the MN and HR buttons to enter the code from STEP 11

14. Press the AM/FM button. The radio display changes to SEC Your radio is now “un-locked” and usable. The Theft-Deterrent feature is STILL active! If you want to disable it, use the instruction on page 3-27 in your Owner’s manual. Use the code from STEP 11 instead of your personal code.

I hope this helps
