Is it a cassette player? Delco-Loc or Delco-Loc II?

 

If it's Delco Loc 1, simply turn on your ignition and flip on your lights. The radio should unlock itself.

If that doesnt work, try this. I think this is for the Delco Theft Loc-II

 

Stop letting the GM dealers charge you $50-$60 or more to do this procedure that a five year old could do in less than five minutes! Here you go:

 

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.

 

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).

 

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 here,

press the number of your choice, followed by 02107 and hit the # key. He'll ask you

for the 6 digit code that you've written down. Enter that and press the

* key. He will then give you a code, and the option to get additional 4

digit codes, but one should be sufficient.

 

4. Follow the normal procedure in your owners manual for unlocking the

radio with your new code...press the hour set button on your radio until

you get the first two numbers of the code, then press the minute set

button until you've entered the last two numbers. Immediately press the

AM/FM button once the correct code is entered and the code SEC or

"secured" will be displayed on the display screen. Now, just turn the

radio on, and your ready to roll.

 

There is an additional step you can take to remove all codes from the

radio and start from scratch by entering your own personalized 4 digit

code so that it won't get you in a pickle again! Just repeat step 4 and

you should get a display screen that reads ---. This means the code is

out, and you can now program your own code. Of course, once you receive

the 4 digit code from the GM recorded message, just keep it in a safe

place, because you can use that same code again and again should you

have any more problems with it in the future.

That's for Delco-Loc II and Theftlock. Delco-Loc I simply communicates with the steering wheel controls to unlock itself.
