How do you unlock a radio in a 2007 Pontiac g6?
Dial 1-800-537-5140 to connect with GM's toll-free radio hotline. Once you're connected, you'll be asked to provide your vehicle's radio identification number, along with a special dealer access code. You'll then be rewarded with a 4-digit retrieval code, which will allow you to unlock your radio.

Turn on your radio and see if it displays CODE or LOC. If it does, turn off the radio. Press and hold down the audio power button together with the SEEK button for about 50-60 minutes. Then, it will turn on without entering the radio code.

I'm pretty sure you'll need to contact the manufacturer of the radio about a security code, or maybe your local VW dealership can help you if the radio is stock. I'd try the dealership first.

see this technique and fix it. God bless you
Instructions

1. With the Unlock Code
   • 1 Locate the anti-theft/unlock code. Most cars have a special anti-theft radio card that is included with the owners manual packet containing the unlock code and serial number. Some cars also have the code in the car manual or inside the glove compartment. You will need this code in order to unlock your car radio.
     
   • 2 Turn the car's ignition switch to the "on" position. This turns on your car's electrical system and powers up the radio. The word "CODE" will display on the screen. Note: depending on the manufacturer some radios will display either "ENTER" or "LOC" on the screen instead.
     
   • 
     
     
   • 3 Enter the anti-theft/unlock radio code. Press the "Tune" button on your stereo. It will change the screen from "CODE" to blank. Press the button to scroll through the available numbers. When you reach the correct number press the button once and hold it down for a few seconds. The number will appear on the display and you can now repeat the process to input the second number, third number etc., until all of the numbers are in. If you entered the code correctly the car stereo will unlock and instantly become functional. Depending on your car manufacturer, if you enter the code incorrectly you will not be able to re-enter it again from 1 to 24 hours.
     
   Without the Unlock Code
   • 4 Call your car manufacturer directly. Your car manufacturer's phone number is in your owner's manual. Ask to be connected to the support department. Tell them you need to reactivate you car stereo and you will be asked for proof of ownership. They will need your car's VIN number, the account number from your bill of sale and a form of personally identifiable information like your driver's license. You may need to fax this information. Once everything checks out the manufacturer will give you the code.
     
   • 5 Enter the code and unlock your stereo. Use the code you received from the manufacturer to unlock and and activate your car stereo.
     
   • 6 Go to a car dealership. Take your car to its manufacturer dealership to get the stereo unlocked. For example, if your car is a Honda go to a Honda dealership. Once you have proven that you are the owner of the car, the dealership will be able to retrieve the code from the manufacturer and activate the radio for you.
     

You need to contact a GM dealership to have them verify ownership and lookup the code for you if you do not have it in your owners manual.

You need to call the car company or take it to a car dealership to get the code for the radio to unlock it.

You will need to take the car to a dealership to have the service department unlock the radio for you. They have a special code to unlock the radio and then you are required to change the code to one that you will remember. An appointment should not be needed because this takes about 5 minutes. I do not remember the code, sorry.

in order to get the code for that car you are going to have to call the dealership. and give them the specs on your car and maybe even your vin number.

YOU NEED THE RADIO's SERIAL NUMBER:
I don't know an easy way to get the radio serial number, find a radio install savy person and ask them to help you. My dealership said they would do it for me and charge me for 30-60 mins worth of labor.. (At $75/hour) <BR> <BR>
RADIO SAYS "OFF" OR "LOCK": <BR>
Leave the "off" display on for 1 hour uninterupted, then it will automatically reset back to UNLOCK CODE.
<BR> When you turn it back on again after that time has passed it will ask for "code". <BR> <BR>
RADIO SAYS "UNLOCK CODE:" <BR>
Call your local MItsubishi dealership and ask for the service department.
<BR>They have a computer program where they punch in the serial number from your radio (you have to supply the number) and it will tell them the UNLOCK CODE for your radio. My dealership offered to give it to me free over the phone, if I knew my radio serial number. Enter the code using the buttons on your radio. And write the code down, this will show up everytime your radio looses connection to its power source - the car battery.

If you need it - I called 360-696-2277 which is the local Mitsubishi Dealership for me here in Washington State. They were the ones who offered to give it to me over the phone..
