Radio locked on my 98 grand prix need unlock code

If you take the registration document to the dealership, they will give it to you for free. Also look for a small white sticker in the glove box or owner's manual.

There are also companies on the internet that will sell you the code based on the serial number of the set.

This is a problem with the Theft-Loc system. I believe you will have to take it to the dealer to have the radio unlocked. I found this procedure on the web, but I don't know if it will work. Good luck.

1. Turn the ignition ON (The radio should display "LOC")

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

3. The radio display changes from LOC to a three-digit number. Write this number down. You now have fifteen seconds to complete the next step.

4. Press the AM/FM button

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

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

7. Call 1-800-537-5140

8. Press 1 then # (pound). You'll hear "Invalid Code, try again"

9. Press 139010 or 106010 or 206010 or 202107 then # (pound). You will be asked to enter your four or six digit code followed by *

10. Enter the number from STEP 6 then *

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 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.

Jake

Hope this helps; keep in touch.

go to this website and it will help you unlock it. --www.oqcgp.com/forum/kb?mode=article=53. good-luck!! when page comes up click on ontario quebec club grand prix, general motors theift unlocking radio. the knowledge base will come up, and here are the directions how to unlock factory radio.

The radio comes with a preassigned lock code that must be obtained from Pontiac. They will need you to follow these steps to retrieve two sets of numbers for them to call GM and obtain the assign lock code for your radio. STEP ONE: Press number 2 and number 3 simultaneously. Hold until the first set of numbers appear. Then press the AM/FM button on the radio for the last set of numbers to appear. Give those numbers to Pontiac, and they will call for the radio lock code. They will also provide you the steps to enter that code to unlock your radio.

I suffered the same problem. Turn your ignition key to the ON position for 1 hour. This will reset the double lock feature on the radio to prevent theft. Once you leave your ignition key on for 1 hour, turn the key to the off position. Remove the key. Then turn the ignition key back to the ON position. You should then see "LOC" instead of "InOp". Then try the steps to enter your code again. Three incorrect tries will enable the double lock feature again, and you will have to repeat these steps to reset it.

you will need to bring it to a dealer and they can unlock it takes about 1 hour they need to retrive master code and then they go to a gm site and they give them the unlock code

The code to unlock the radio is in your owner's packet, each radio is unique and has it's own code, call the dealer they may be able to get the code using your VIN number.
