The following procedure will give you a new code that you can use instead of your personal code. Using this new code, you can “unlock” your radio and then “re-lock” it with a new code if you wish. Prerequisites: The radio must be in LOC mode NOT in INOP mode. Let me explain. If you have activated the Theft-Deterrent feature of your radio and loose power, the radio goes into LOC (theftlock) mode. With the ignition on, you must use the MN and HR buttons to enter you personal code in order to unlock it (The instructions are on page 3-27 in your Y2K Owner’s manual). If you fail to enter the correct code eight (8) times, the radio goes into INOP mode. You have to wait an hour with the ignition on before the radio returns to LOC mode (go for a long drive somewhere).

Procedure:

01. Turn the ignition ON (The radio displays LOC)

02. Hold down the Radio Presets 2 and 3 buttons for six seconds

03. The radio display changes from LOC to a three-digit number. Write this number down. Don’t take forever, fifteen seconds max before the next step.

04. Press the AM/FM button

05. The radio display changes to another three-digit number. Write this number to the right of the first one.

06. You now have a six-digit number, the first three digits are from STEP 03 and the last three digits are form STEP 05

07. Call 1 800 537 5140

08. Press 1 then # (pound). You’ll hear “Invalid Code, try again”

09. Press 139010 then # (pound). You will be asked to enter your four or six digit code followed by * (start)

10. Enter the number from STEP 6 then * (star)

11. Listen to the four-digit number and write it down. It will be repeated twice

12. Turn the ignition ON (The radio displays LOC)

13. Use the MN and HR buttons to enter the code from STEP 11

14. Press the AM/FM button. The radio display changes to SEC Your radio is now “un-locked” and usable. The Theft-Deterrent feature is STILL active! If you want to disable it, use the instruction on page 3-27 in your Y2K Owner’s manual. Use the code from STEP 11 instead of your personal code.

Note: This tip originated from LOTZAHP, Austin TX (credit must be given where credit is due). I verified it on an Y2K C5 with a locked radio - mine.





I hope this helps, I found it on a corvette forum, should work fine with your radio. Again let me know how this turns out. Please.

You cannot use this procedure wth 2001 and up GMs.Has to be done with the Tech 2 and is faster than the old procedure

[madyareh]

Is there any other way to enable the RDS radio besides taking it to a dealer? I have access to a code reader and programmer for the regular error codes. Any way thorough that method?

[madyareh]

Actually, my rds radio is from a 2002 or 2003 Pontiac Sunfire and I am trying to put it in a 2000 Chevy Cavalier. Is this even doable? Can the tech 2 even mesh these dfferent systems? I don't want to pay a dealer to tell me he can't do it.

I'm glad I found this.....I have a 95 Lumina and I got a radio out of a 97. It was locked. Now, after looking at this thread, went thru the procedure.....it works now.
Thanks for the help!

Hi,

I imported a 2006 Chevrolet Blazer from Canada to Saudi Arabia, and got a locked radio in.

the 2&3 button thing doesnt work tried it many times and tried it with ignition on , car running all sort of ways.

Is there anyother way out? Wanted to go to dealer but we have only 2 located in our city and they have one hell of a rush. Probably would waste my whole day there if i dont get a solution.

[zzyzzx2]

Post the codes from the radio and maybe someone here will call the 800 number code for you. I'm assuming you are getting the Theftlock code.

Hello everybody,

Thank you very much for this valuable information.

I have an inquiry please.

Kindly tell how to disable the Theft code.

6CD Bose player in my Envoy XL SLT 2003
I live in Saudi Arabia, Middle East and the car came from the United State and the Radio frequencies here in Saudi is different.
I went to dealer shop he checked and said it's locked I can't reconfigure it to Middle East (I think he doesn't know how :-( )

So I need to disable the Theft Code and go back again to him ;-)

Or I will be very greatful if you have a way to do so by myself and save my money.

Thanking your kind co-operations,

AJ
