    Typical GM….holding your radio hostage

  10. Avataaar/Circle Created with python_avatars Me Blake says:

    What good is unlocking the radio with the autel if it doesn't give you the unlock code? When that car battery dies, the radio will loc.

  11. Avataaar/Circle Created with python_avatars Andrew Cordova says:

    Well now make sure when u take key out and back in it still works

  12. Avataaar/Circle Created with python_avatars Patrick Snow says:

    That’s great if you have 1200-2500 dollar computer to fix 25-50 wrecker radio
    Honestly wasteful video

  13. Avataaar/Circle Created with python_avatars Loren Lyons says:

    Can you do this with a 2015 GMC radio? with 7" screen?

  14. Avataaar/Circle Created with python_avatars Liam Elm says:

    hey which scan tool do you have?

  15. Avataaar/Circle Created with python_avatars Bruce Wagenberg says:

    How do I do it without an expensive scanner, or can I borrow yours, or just come by?

  16. Avataaar/Circle Created with python_avatars panzer waffen says:

    How much cost this

  17. Avataaar/Circle Created with python_avatars Jamey Barisoff says:

    You could get a light bulb to light up the display properly.

  18. Avataaar/Circle Created with python_avatars Ojobor says:

    can you give me information of the scan tool you using, i mean the odb diagnostic scanner

  19. Avataaar/Circle Created with python_avatars BUSTER says:

    what kind of after market radio would work?we dont have that $$$$$$ computer.thought you were smart,to help us

  20. Avataaar/Circle Created with python_avatars James Gray says:

    Which Autel did you use

  21. Avataaar/Circle Created with python_avatars Lance Lafonde says:

    Well thanks man, what happens if we don't have a fancy code reader like yours? Need info on unlocking without a reader.

  22. Avataaar/Circle Created with python_avatars Bige4u says:

    Around 2003 and later, the brand new GM radio eprom chip is blank, once the vehicle is turned on for the first time at the factory, the BCM(body control module) finds the radio, its then programed to the VIN# of the vehicle, therefore "locking" it to that vehicle only. The "data bus" connection to the radio verifies the radio at every vehicle startup and allows it to turn on only if the feedback info from the eprom chip is correct. These high dollar scanners, as seen in this video, can actualy reset the eprom chip back to zero VIN, so when the radio gets installed into a different GM vehicle, within a set number of years of course, along with similar radio wiring connections, once again, the BCM comes into play and reprograms the radio for that vehicle.

    Oh good its called "have a 5000$ scan tool" thanks scotty kilmer

  24. Avataaar/Circle Created with python_avatars llAntimatterll says:

    Okay, so for anyone who doesn't have a $700 – $3000 scan tool and has a factory Delco radio that are in all sorts of different GM vehicles, you can call and get the code to unlock it. You don't have to talk to anyone, it's automated, and this all takes 5 minutes to do.

    To do that, you need to get the 4 or 6 unlocking digits by hitting the number 2 & 3 preset buttons at the same time (which will show you 2 or 3 digits on the display) and then hit the AM/FM button (gives another 2 or 3 digits). Make sure to write those down and you should now have the 4 or 6 digits you need.

    Now, call GM's automated dealer hotline for Delco radios (1-800-537-5140) and input one of the following five dealer codes, followed by the star key, until one of them is accepted – 620529, 139010, 106010, 206053, 202108. When the automated line accepts one of those codes, just enter the codes you got on the stereo screen earlier, followed by the star key, and then the automated line will give you a 4 digit number back.

    At this point you just need to enter that code into the stereo. To input the code, use the 'Hr' and 'Min' buttons for the clock. Input the digits from right to left starting with minutes and then hours, and then hit the AM/FM button. Radio should say "Sec" on the screen, which means 'secure'.

    Finally, just hit the power button, and the radio should now be back to functioning like normal. Hope this method helps for those who don't have a good scan tool.

    Seems autel took this out of there scanners tried on a 05 envoy today was not an option to unlock radio anymore

  26. Avataaar/Circle Created with python_avatars creagermatthew says:

    Would an aftermarket radio need to be unlocked?

  27. Avataaar/Circle Created with python_avatars Luella Hampton says:

    This is all great and good but how does a normal person without that fancy tablet fix their own car because there isn't a SINGLE video on here that showed her how to take the working stock stereo out so she could upgrade to a nice Sony touch screen without locking down the entire stereo setup?!!!!!!!! I am so frustrated, I even tried reinstalling the stock stereo and it still won't work

  28. Avataaar/Circle Created with python_avatars John Jacobs says:

    I couldn't find an independent mechanic who had the Autel software for GM. I did find that for $40 for a one time use, a mechanic with a compatible Autel could do what this guy did. You need to find a mechanic or body shop who will do this. I finally paid the GM dealer $257.55 (including taxes) for unlocking. That was $75 for diagnosis and $130 for unlocking – plus shop charges and taxes. Good luck finding an independent shop willing to spend the time with this Autel solution.

    What computer did u use and model

  30. Avataaar/Circle Created with python_avatars qxANGELxp says:

    So I just bought a radio.
    I guess my solution is to take it to my local shop next time I get an oil change and just ask them to reprogram it for me. Easy fix, but it would've been better if I could just do the "Press 2 & 3" cheat like the older radios could.

  31. Avataaar/Circle Created with python_avatars SerenoOunce says:

    Out of curiosity I tried this w/ a Launch as well. It has a radio section but not a setup option. The Launch does have a few shortcomings but as a backyard mech it was still a good investment though. Alternative is to either pull the lock chip out or if you have a hot air station swapping them should work too to avoid the "config error" msg.

    Pls how can i reprogramming Cadillac CTS 4 pcm manually please help me

  35. Avataaar/Circle Created with python_avatars Tom M says:

    I don't have one of those nice computers you have and after reading some of the results of clearing the lock on a 2007 Cadillac Escalade I'm afraid to take it to a dealer after replacing my radio and CD player. Cadillac on one occasion that I read about bricked the radio and won't take responsibility. Too bad your garage isn't close to where I live.

  36. Avataaar/Circle Created with python_avatars Jim Vet says:

    good-job

  37. Avataaar/Circle Created with python_avatars Toll Keeper says:

    Have a question about the Autel 908. It can unlock radios, can it also program the PK3 systems? Considering getting one of these units. Can you possibly go into what you do like and not like about this particular unit? Other features?

  38. Avataaar/Circle Created with python_avatars Derek Brown says:

    Which model Autel do you have? I would love to unlock an OEM radio in my POS Trailblazer

  39. Avataaar/Circle Created with python_avatars John Jacobs says:

  40. Avataaar/Circle Created with python_avatars Carola Cespedes says:
