How to Unlock Chevrolet Theftlock Radio

To unlock your VW factory radio from "SAFE" mode, you will need to enter the radio code. Typically, the code is written on a radio card included with the documentation for the vehicle when the car is first sold.

If you don't have the code, or have lost it, you can retrieve it by visiting your VW dealer. You will need the car's VIN number and the serial number of the radio (located on the body of the radio).

The procedure to enter the code is as follows:

Press the "MODE" and "SCAN" buttons simultaneously and hold them until "1000" appears on the radio display. Release the buttons as soon as this number appears.

Refer to your Radio Card and use the station preset buttons ("1", "2", "3" and "4") to input the code. Press the "1" button repeatedly to input the first digit, the "2" button to input the second digit, etc.

Press and hold the "MODE" and "SCAN" buttons simultaneously until "SAFE" appears again. Release, and the radio should be unlocked.

Do not enter the wrong code more than three times, or the radio will lock itself. Note the dealer can also enter the code for you (they may charge a small fee).

Hi , LOC means radio is locked....1. You can retrieve a set of factory numbers in the radio that enable you to get a unlock code . If it says INOP you will have to leave the key in the ON position or let the car run for at least an hour before you attempt any unlock procedure .INOP means a secondary theft lock due to too many attempts to unlock radio........2. look at the face of your radio and hold down the preset buttons 1 and 4 or 2 and 3 ( depending on year and model , if 1+4 don't work use 2+3, ) for about 10 seconds or until a set of 2 or 3 numbers come up on the display. Write these numbers down.......3. Next press the AM/FM button, a new set of numbers will now show. Write these numbers down. You will then need to call an 1-800 no. with the numbers you have written down to get the unlock code. Try calling a GM dealer and ask them to do it for you, or some sites on internet will get for you for a fee.....4. Once you have the unlock code enter it by pressing the MIN button until display shows the last 2 digits of the unlock code, then press the HR button until the first 2 digits of of unlock code are shown. Then press the AM/FM button to enter the code. The radio will now display SEC and normal function is restored.

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!

Hope this help (remember comment and rated this).

Your code is 3053

Use preset 1 to set digit 1, preset 2 to set digit 2, etc
Once the code displayed is correct, push your unlock button to unlock the radio.
The unlock button varies by model, but is always either AM/FM, CD, or TAPE.
There is no penalty for pushing the wrong unlock button as long as your code is correct.

If you have locked out the radio from failed code attempts (radio reads "OFF", you will need to leave the key in the ACCESSORY position with the radio displaying OFF for approximately 1 hour. After which time the radio will revert to CODE and you can enter your code then.

If you do not have the code. look in owners manual some times it is written in there or there is a card with code on it. if not you need to go to a volvo dealer and they can get the code for you. You may have to pay them for 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.

If your lucky the dealer may still have it or the code may be written down at the back pages of your manual. The other place where you can get the code would be www.radio-code.com. before you try any of that, try 0000 to unlock your radio. Good luck and hope this helps.
