Good luck

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!

The code is different for every radio. The only way to get the radio lock code would be to go to a dealer. Some dealers will do it for nothing, others will charge you about 50 to 60 dollars to retrieve and unlock the radio. It is possible that the dealer will not be able to retrieve the code and you may have to put in a after market stereo into the car(I had this happen to me once). If you don't have the code, your best bet is to take it to the dealer as putting in too many wrong codes will only further lock your radio and prevent you from making further attempts.

I recently had my starter motor replaced. When I got in to drive my car the radio was showing "CODE" I have the code for my radio serial number (if you don't then you will need to get the serial number from the back of your radio unit and call your local BMW dealer, they have a database that they can look up for the correct code). Nothing was working and the unit kept beeping at me! I was trying everything and nothing was working. I since found out that the unit had "locked" me out! I rang the dealership, they said to leave the car in ignition with the radio on for exactly 1 hour (this resets it) then put in the code. Voila! It worked!

press the hour set button on your radio

you get the first two numbers of the code, then press the minute set

code so that it won't get you in a pickle again! Just repeat step 4
and
you should get a display screen that reads ---. This means the code is
out, and you can now program your own code. Of course, once you
