Call the dealer with the vin number to the vehicle some require the serial number off of the radio itself. They can get you the radio code for the truck. It will not cost you anything.

How do I unlock a radio when it displays the word LOC on a 1997 GMC Jimmy?


It is written in your owners manual. you need a code which the original owner would have written down somewhere in the manual. If no code, no radio. Only the dealer can unlock and make new code.

2000 GMC Safari, lost power to the vehicle. The radio did disply 'loc' and now displays 'InOP'. Please Help


Hi

Thanks for using FixYa. 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).

After that the the radio will go to LOC mode, then follow this procedure to unlock it—

To unlock the car radio - Have a pen and paper ready. Push and hold stereo preset buttons 2 and 3 simultaneously for several seconds. Three digits will appear in the display "XXX", write them down. Push the AM/FM button, three more digits will appear in display "YYY", write them down.

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

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

Enter the six didgit number obtained from above procedure.

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

Turn the ignition ON (The radio displays LOC)

Use the MN and HR buttons to enter the $ digit code that you have heard.

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 in Owner’s manual.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

Good Day,

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 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 Owner’s manual. Use the code from STEP 11 instead of your personal code.

I hope this helps
