This is the process for the CD deck. I assume it's the same for any 88-90 deck with the DelcoLok system. It may also work with 90+ DelcoLok I units.

1. Press and hold presets 2 and 3 for about 5 to 10 seconds until you
get 3 digits on your display. This is the first 3 of 6 digits you will
need, so write 'em down. (mine were 881)

2. After doing step one and writing down the code, immediately press the
AM/FM button to get the last 3 of the 6 numbers you'll need, and write
'em down. (if you wait too long between steps 1 and 2 and the LOC code
displays again, just start over). (mine were 322)

3. Call this number, it's a prerecorded message, so don't worry about
having to talk to anyone...1-800-537-5140. The voice will ask if you're
calling for Chevy, Pontiac, Cadillac, etc... When you hear this,
press 1 for chevy, followed by 02107and hit the * key. (i.e. 102107*) He'll ask you for the 6 digit code that you've written down.(mine was 881 322) Enter that and press the * key. He will then give you a code,(mine was 810 891)

4. To unlock the radio:

A. Turn the ignition on.
B. Press "SET" (000 appears on display).
C. Press "SEEK until the first digit of the code appears.

D. Press "TUNE" until the second and third digits
E. Press "AM-FM" (000 appears on display).
F. Press "SEEK" until the fourth digit of the code appears.
G. Press "TUNE" until the fifth and sixth digits of the code appear.
H. Press "AM-FM". Now the radio can be turned on.

see that help you good luck!!!!

Here's another variation that worked for me just two days ago... you DO NOT NEED to take it to the dealer and you do NOT need to disconnect the battery, this can all be done with a couple clicks on your radio and call into that phone number.

This was posted previously on another post. ....
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 from STEP 05

07. Call 1 800 537 5140

08. Press 1 then #. You’ll hear Invalid Code, try again

09. Press 139010 then #. 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

You may have to take it to a GM dealer and have them reset it. You might try disconnecting the battery first.

How to Unlock a Delco Radio - Instructions

1) Obtain the six-digit dealer code - yours is above. ( this doesn't apply: Contact your local GM dealer. If you explain the situation, most will provide the code to you. If they are not willing to provide the code, contact other GM dealers until you find one that will help you

2) Turn the ignition key to the "ON" position, without turning the engine over. Hold the preset buttons "2" and "3" for 10 seconds. The radio will display a three-digit code. Write this number down and then quickly press the "AM/FM" button. Three more digits will be displayed. These six numbers are the serial code for your radio.

3) Call the GM assistance hotline at 800-537-5140. Follow the prompts and select the brand of your vehicle. Enter the six-digit dealer code and then enter the six-digit radio serial code. The automated system will provide you with a four-digit code to unlock your radio.

4) With the ignition on, use the "Hour" button on your radio to input the first two numbers of the four-digit code. Use the "Minute" button to input the last two digits. Press "AM/FM" to set the code. The radio is now unlocked and ready for use.

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.

Search the net for "Delco unlock codes" OR "Delco security codes" you should easily find a set of instructions telling you to get a code from your radio and then call an 800 number. Follow these instructions. This will give you the factory unlock code for your stereo. Worked for me and for heaven sakes don't pay anybody for this information - it's free.
