9. I have an 2006 Saturn ion I bought a used radio out off the same year car from salvage yard . It shows in the xm mode that its theft locked everything works on the radio but can not hear anything. You can do everything change station all functions work but no volume?

   1. did you ever have any luck? Same story here but I have a 2006 cobalt

10. this trick only works when key is off. on mine

11. I have a 2002 Buick LeSabre and my radio says locked on it how do i unlock it myself

12. this does not work on newer radios, they are synced with the cars vin number stored in the body control computer, if you play with the button too much you will “brick” the radio and it will display INOP, meaning its not recoverable..go for an after market radio if your original one crashes..why do you think junk yards only sell them for 20 bucks, they know they are worthless..

13. I have a 2000 imapala and this didn’t work on it yet it has the same radio as displayed

14. I tried everything it says on here and it still won’t work. What else can I do?

15. I installed a My Link touch screen system (from a wrecked vehicle – 2015 Trax as well) to replace the standard one in my 2015 Chevrolet Trax and everything plugged straight in. However, I am getting a “locked” message on the screen and I can’t press any buttons… Do you have a solution to this issue?

    1. Radio must be programmed at a dealer using a MDI Scantool.

16. Nope didn’t work

17. Thanks hope this work I had this car from 2014 no crank. Theft lock

18. nothing works on my 2008 Chevy impala to unlock radio I got from junkyard

19. My Radio theftlock cadillac 2005 sts

20. What navigation Radio is there a way to unlock them

21. 2007 hhr radio locked. ….tried that sequence and did not work

22. Will this work for a Bose radio also

23. GM is crazy for doing this… Battery replacement is a periodic maintenance procedure… That they would do this to force customers into their sevice departments is an outrage…. So let me see if I understand this… Someone steals my car, removes the battery, and their punishment is they can’t listen to the radio? Seriously? And if its to protect the radio itself… Who would steal the pieces of crap having to tear the dashboard out?

24. I have a 2001 buick lesabre my real does not say locked or loc but I have no sound coming out of it how do I fix it

28. hi i’m Mike from Montréal m’i radio says locked how could i unlock it for good tank’s

    1. Have a cadi changed my 2000 for a 2005 says locked how can I unlock if

29. whoops, I meant to say Chevy Venture Van and not a Chevy Cavalier!

30. We have a 2004 Chevy Cavalier. With key on, but not turned and door open, you push right seek, plus the 5 button and power. It works fine, but as soon as you start it, it goes back to lock. Any ideas?

31. Does it work for a Bose radio in a cadillac? I did try it and nothing happened.

32. Anybody know the complete sequence to unlock permanently a “locked” GM Radio?

33. i have a 2003 Oldsmobile silhouette, says locked..wondering how i get it unlocked..changed radios from my old 2001 radio too my newer 2003..changed it because i had no sound coming out my newer 2003 radio..any helpful hints

34. Regarding 2002 Pontiac Sunfire
    My radio says Locked when i start the car
    I have the VIN # for both the car the radio came from/wrecking yard ,and my car
    Is that any help ???
    All other button pushing has no response

    1. I have the same car and same issue. Did you ever figure out how to get it unlocked on the 2002 pontiac sun fire?

35. My radio has up down seek buttons(2001 pontiac aztek), not the right left, tried the sequence with both, up first no luck, then down seek no luck, any ideas?

36. This trick didn’t work on my chevy silverado 2005 does anyone know what else to try? I bought this stero from a friend of min

37. Same as ljnks. 2005 Suburban

38. Did what you instructed no luck, did what TekWiz did and it unlocked until the acc/power was turned on then just back to lock, also could’nt change stations. Think just have to pay the 150.00 at the GM dealer to fix it or buy a aftermarkert kit.

39. Got an issue. The above process works on a Cadillac CTS 05 navigation system but I have an issue with the fact that the sound isnt playing or anything. It does put the system in safe mode but it does not allow me to change radio stations and the sound isn’t playing through to the base speakers on the car. Is this an issue with the safemode or with installation? I just need some answers. Thank you.

40. Can anyone tell me what needs to be done for my factory radio? My 2001 Chevy Tahoe battery went out so when I put in a new One my radio shows nothing on the screen. Red light blinks and when I push min hr it quickly shows the time. I can also pull up the 6 digit code but nothing further than that. Please help

41. Worked for me with an extra trick…. No Key In Dash … but Drivers Door Open… With the Drivers Door Open The Locked Message Went Away and Gave Me A Blank Screen…

    I was able to use the Right Seek and #5 Keys together and press power
    and test the radio…

    My CD Did not eject on this junk yard radio… I would hate to activate it and
    find out that I paid $120 and my CD Don’t work…

    Thanx to all for the good 411

    1. This worked for me thanks for the suggestion. At least now I know the radio works.

42. WILL.IT WORK WITH THE NAVIGATION SCREEN STEREOS? I THINK OFF A SILVERADO OR TAHOE, I PUT IT ON MY CAVALIER AND IT FIT BUT.IT WAS LOCKED

    1. Hey Jesus-
       I’m interested in that navigation install you did on your cavalier. Do you have any pictures of the install? The trick shown here will -not- work on the “THEFTLOCK ENABLED” screen of a GM navigation radio. You will have to get it cleared at a GM dealer with a Tech 2 scanner and there’s a trick or two involved. Let me know where you’re at with this project.

       1. By the way I have tried it and it will work on such a system.

43. how about the 2009 and up models tried all recommended procedures including removal of EPROM that resulted in a no vin response when you press the eject button on the cd this also has an mp3 plug to use any ideas ?

44. The button sequence works for me , but only if key is put into ignition, and not turned. The radio screen at this point is blank and after entering button sequence radio is fine, but then when car is started locked is displayed and again nonfunction. If I follow instruction exactly radio displays locked initially and does not allow or recognize button sequence.

    1. Same here how you fix it?

    2. Right somethings wrong with my truck. Lol :p

45. Disconnect/cut the pink wire and the two skinny green wires. They are to the alarm/security system. Then Press 5, seek and power at the same time. If it does not work your radio is not in the lock mode. This will work, but occasionally the radio will cut off, so you will have to press 5, seek and power, each time you turn it on. This works on my 2005 Malibu (new body style)

46. Make sure to hold down Right Seek and Preset 5 before pressing the Power button

47. I have a 2000 Olds Silouette which the CD player quuit working after the van was sitting for 10 months.
    I got another identical radio from a 2002 Chevy Ventura & installed it.

    The display reads “LOCKED”

    I tried the Right seek with perset #5 & power on.
    Nothing happens.
    I also tried the preset 1 & 4, also, nothing happens.

    Is there anything more i can try or do.

    Thank-You,

    William C. Francis

48. I tried the preset 5, seek forward,power on, ,,,,,,,nothing at all. Am I doing something wrong..? Thanks
