Your best bet is to call a local Volvo dealer. They can look it up for you. You will at least need the VIN. It may also help to have the radio S/N in case the radio is not original to the car. There are two tabs on the left and right of the radio. One is to the left of the bass slider and one is next to the 6 preset button. Push these in with a small screwdriver and record the numbers on the white placard. If the local dealer is unable to provide the code for you, contact me and I can get it for you.

    I cannot get the radio code to solve the "off" on my 98 volvo s70 GLT. Vin number, YV1LS5671W2497933. The radio serial number is V01610X0021100H, other number: 353377-1

    PLEASE HELP. Also turned key to first position for 1.5 hrs, nothing reset, should I disconnect batter cable and reconnect after a while to get to "code" screen on the radio?

  • VolvoDarin Sep 12, 2011

    Disconnecting the battery will not reset the radio. Leaving it on in the first position is the correct way. Might not have been long enough the first attempt. Try it again and leave it on until it displays code.

Radio code


No one on the internet will have your radio code
It is a security feature & you own the vehicle & don't
know it
See a dealer & ask the question,how do you get or retrieve
the radio code & then put it in the system

What are radio codes?


  • It an electronic security code for the radio that avoids radios being stolen from cars because then they will not work once power to them is disconnected due to either their removal, disconnection of the car battery or a flat car battery.
  • Once the radio has lost it's power source it cannot be operated until power is reconnected and the code is punched into the radio using the radio controls. The code for each radio is different and is supplied with the car when new. If you do not have the code you need to contact the service department of the new car dealer that sells that brand of car who will likely charge you a fee to look it up for you if the records are still held.

When i try to turn my radio on it says loc hoow do i unlock it?


Does your GM car or truck Radio display LOC and does not turn on? Chevrolet, Buick, Pontiac, GMC, Cadillac, Oldsmobile vehicles used a theft system to lock the radio when power is lost. This system was used from the ealy 1990's to the early 2000's.

Instructions:
  1. If your radio displays the word LOC, you can retrieve a set of factory numbers in the radio that enable you to get a backup unlock code. If the radio says INOP, you will have to leave the key in the "ON" position, or let the car run for at least 1 hour before you attempt any unlock procedure. INOP means a secondary theft lock due to too many false attempts to unlock the radio.
  2. Looking at the face of your GM Delco radio, hold down the preset buttons 1 & 4 OR 2 & 3 (Depending on year and model) for approximately 10 seconds or until a set of 2 or 3 numbers comes up on the display. Write the numbers down.
  3. Next press the AM / FM button. A new set of 3 numbers will now show. Write these numbers down. You will then need to call a 1-800 phone number with these numbers to get the unlock code. There are many sites on the internet that can get it for you- for a small fee. Or, try calling your local GM Dealer and ask for them to do it. Many times they will do it for free. It only takes a minute.
  4. Once you have the unlock code, enter it by pressing the MIN button until the display shows the last 2 digits of the unlock code, then press the HR button until the first 2 numbers or shown. Then press the AM / FM button to enter the code. The radio will now display SEC, and normal function is restored.
Also, its possible that you need RESET your GM Radio; this is the procedure: While performing maintenance on your car, you may disconnect the radio from the battery in your GM vehicle. GM cars contain Delco radios that are protected by Theftlock, which locks the radio after it has been disconnected from a power source. Iit can only be reset and unlocked with a car-specific security code. Identifying the security code for your GM vehicle is the only way to reset the car radio and disable the Theftlock protection device.

Instructions:
  1. Turn on your car. Your Delco radio will show "LOC" in the LED display.
  2. Press and hold down both the second and third preset buttons. Hold these buttons down for at least six seconds.
  3. Write down the two- or three-digit code that appears in the LED display.
  4. Press the AM/FM button on the radio.
  5. Write down the next two- or three-digit code that appears in the LED display. You should be left with either a four- or six-digit number. Turn off your car.
  6. Call the Delco radio automated customer support line at 1-800-537-5140.
  7. Press "1" and then press the pound sign. The automated voice should respond "Invalid code, try again."
  8. Enter the number 139010 into your phone and then press the "*" sign.
  9. Enter the four- or six-digit number you wrote down from Steps 3 and 5, and then press the "*" button.
  10. Write down the four-digit code given by the automated voice.
  11. Turn on your car. Enter the Delco unlock code using the procedure outlined by your GM owner's manual. Normally, the unlock code is entered with the "HR" and "MN" buttons on your radio.
  12. Press the AM/FM button. If you have entered the code correctly, your LED display will read "SEC" and the radio will be unlocked.

Security code ?


Did you recently have your battery changed or jumped because of failure? If you have the original owners manual for the car or if your lucky enough to have the owners manual for the radio, You may very well find the radio code hand written on the inside of either the front or rear cover of either manual. Othewise you've got to call the radio manufaturer. To enter the code just hit the nmbers in that you have found.

This may sound silly but place the actual key in the drivers door and cycle locked and unlock this should reset the security system.
