Try this..Turn your radio off, take the fuse out (for the radio) for one minute. Replace it and turn the switch on. Turn the radio on and enter the code. If this dosnt work you may have the wrong code. If you enter the wrong code 3 times it may lock and you will have to wait an hour before entering again.

SOURCE: how to enter security code & where to get it.

If your radio is factory, try calling the dealer where the car was bought. If you dont know then call the manufacturer. Normaly if your radio is asking for a code none of the buttons will respond untill you enter the code. The number buttons work but with no sound. If you enter the code incorrect 3 times it will lock you out, and you will either have to wait an hour to retry or you can try removing the radio fuse for a minute then put it back in and try again.

Hi,
According to your requirement you have to purchase radio code or you can use car radio decoder software to decode your car radio. If you have experienced a dead battery, disconnected the factory radio harness or disconnected the battery to the vehicle then you must need radio code. Better to purchase a radio code. Before purchase determine of your radio type and do the following steps. The radio must be in LOC mode NOT in INOP mode. Turn the ignition ON. Press and hold presets buttons 2 & 3 or 1 & 4 for approximately 10 seconds. The radio display changes from LOC to a three-digit number. Write this number down. You will then have fifteen seconds max before the next step must be performed. Press the AM/FM button. The radio display changes to another three-digit number. Write this number to the right of the first one. You now have a six or four-digit number, the first three digits are from STEP 3 and the last three digits are from STEP 5. If you have a four digit number, it will show all four digits at the same time. Then purchase the code mentioning your car model and unlock the radio. You can purchase your code from radio-code.com by credit or debit card.

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.

For our Toyota Prado 2001 01, after the battery had been removed SEC was showing on the cd / tape / radio display. To remove the security SEC warning, find the last 3 digits of your VIN number (under the hood) hold down the "TUNE" button and then press "1"

Then use the numbers 1 2 and 3 to type in the last 3 digits of your VIN number.

Quickly hold down "SCAN" button, the radio will power off, then press the volume button to turn it back on.

-I accidentally held down "auto" before holding down scan, I don't think auto has any part of fixing this (just an error on my part) but if the above doesn't work, you could try hold AUTO down after entering the digits then hold scan - just as I did.

Hopefully SEC has now been removed, enjoy your radio!

Delco Car Radio


When battery power is removed and later applied to a
secured radio, the radio won’t turn on and LOC will
appear on the display.

Unlocking the Theft-Deterrent Feature After a
Power Loss
Enter your secret code as follows; pause no more than
15 seconds between steps:
1. Turn the ignition on. LOC will appear on the display.
2. Press MN and 000 will appear on the display.
3. Press MN again to make the last two digits agree
with your code.
4. Press HR to make the first one or two digits agree
with your code.
5. Press AM-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show SEC, indicating the radio is
now operable and secure.
If you enter the wrong code eight times, INOP will
appear on the display. You will have to wait an hour with
the ignition on before you can try again. When you try
again, you will only have three chances to enter the
correct code before INOP appears.
If you lose or forget your code, contact your dealer.
Disabling the Theft-Deterrent Feature
Enter your secret code as follows; pause no more than
15 seconds between steps:
1. Turn the ignition to ACCESSORY or RUN.
2. Turn the radio off.
3. Press the 1 and 4 buttons together. Hold them down
until SEC shows on the display.
4. Press MN and 000 will appear on the display.
5. Press MN again to make the last two digits agree
with your code.
6. Press HR to make the first one or two digits agree
with your code.
7. Press AM-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show ---, indicating that the radio
is no longer secured.
If the code entered is incorrect, SEC will appear on the
display. The radio will remain secured until the correct
code is entered.
Theft-Deterrent Feature (If Equipped)
THEFTLOCK is designed to discourage theft of your
radio. It works by using a secret code to disable all radio
functions whenever battery power is removed.
The THEFTLOCK feature for the radio may be used or
ignored. If ignored, the system plays normally and the
radio is not protected by the feature. If THEFTLOCK is
activated, your radio will not operate if stolen.
When THEFTLOCK is activated, the radio will display
LOC to indicate a locked condition anytime battery
power has been interrupted. If your battery loses power
for any reason, you must unlock the radio with the secret
code before it will operate.
Activating the Theft-Deterrent Feature
The instructions which follow explain how to enter
your secret code to activate the THEFTLOCK system.
It is recommended that you read through all nine steps
before starting the procedure.
If you allow more than 15 seconds to elapse between
any steps, the radio automatically reverts to time and
you must start the procedure over at Step 4.
1. Write down any three or four-digit number from
000 to 1999 and keep it in a safe place separate
from the vehicle.
2. Turn the ignition to ACCESSORY or RUN.
3. Turn the radio off.
4. Press the 1 and 4 buttons together. Hold them down
until --- shows on the display. Next you will use the
secret code number which you have written down.
5. Press MN and 000 will appear on the display.
6. Press MN again to make the last two digits agree
with your code.
7. Press HR to make the first one or two digits agree
with your code.
8. Press AM-FM after you have confirmed that the
code matches the secret code you have written down.
The display will show REP to let you know that you
need to repeat Steps 5 through 7 to confirm your
secret code.
9. Press AM-FM and this time the display will show
SEC to let you know that your radio is secure.
The LED indicator by the volume control will begin
flashing when the ignition is turned off.
