Does Your Radio Display Show  LOC or INOP ?
Most GM cars and trucks used a theft system to lock the radio when power is lost,
as with a battery replacement or radio swap.
This system was used from the early 1990's to the early 2000's.
Buick
Chevrolet
Cadillac
GMC
Pontiac
Oldsmobile
If your radio displays the word LOC or INOP  you can retrieve a set of factory
numbers in the radio that enable us to give you an unlock code.
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
3 numbers comes up on the display. Write the numbers down.
Next press the AM / FM button. A new set of 3 numbers will now show. Write these numbers
down. We will then use those numbers to get the unlock code.
Give us those numbers during check-out.
Unlock code and simple instructions to enter it will be sent by e-mail within 1 hour, guaranteed!
Why pay the Dealer up to $100 to unlock your radio ?
Don't sit in the waiting room for an hour.
We get your unlock code just like they do at the Dealer, because we are Dealer mechanics.
We send your code and simple instructions within 1 Hour !
*  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.
Example: First set of numbers is 234
Second set of numbers is 789.
Send us the number 234789.

"It worked great thanks for the help!!  The nearest Chevy dealer is 100 miles from me and
he would not tell me the code over the phone. He tried to tell me the only way to get the
code was to hook my car up to their computer. Thanks for saving me gas money not to
mention what the dealership would have charged."- Lewy from Logan, UT.

to you.. I am so thankful."- Cindy from Houghton Lake, MI
"Yeah thank you very much :)
Being without music for 5 months has been hard so it is very much appreciated!
I'm in the UK too so have not been able to get any help with it at all.
So thanks again".- Aimee from Teynham, Kent, UK.
"I had to have the battery replaced since it was original and didn't realize that any power
interuption would activate the anti-theft device. I know the Sears store took precautions,
but what a not so fun thing to have happen. They researched another dealership that
could fix it for me for about $200. Not excited with that info. So you all are my heros and
the  CD player/clock/ radio is back online.Thanks again for the help -
immensley appreciated  :)"
Lorell, from Spokane, WA
