In order to get the code you need to go to a Chevy dealer with the VIN of the car it came in, the number from the radio and proof of ownership. The have a "dealers only" number to call the radio manufacturer to get the codes. I hope this helps, take care. If you have more questions or just want to say Hi! Use testimonial to comment. Thanks.

With key in "on" position, but pickup not started, press the "SET" button and the "channel up" button (aka "TUNE +"). "SET" appears in radio window.

Now the "SEEK" button will increment hours and the "SCAN" button will increment minutes.

Once correct time is set, press "SET" button again to get out of clock set mode. "SET" will disappear from radio window.

SOURCE: GM Delco Radio unlock code

There are 2 types of GM Theftlock, Theftlock I and Theftlock II.


The Theftlock I is found in pre 2000 vehicles and Theftlock II is

in the latter models.


Theftlock I - Uses a volatile code that is input through the key

pad on the front of the Radio. If the power is lost (dead battery

etc.) the code is gone and must be re-entered for the radio to

work.


If you do not have the code, you can get it by phone, email, etc.

but you will need the 6 digit Radio ID number.


To get that, just turn on the ignition and hold down the 2-3 keys

(sometimes 1-4) and the first 3 digits will appear in the display.

Then hold down the AM/FM button and the last 3 digits will

show up.


With this number you can get the unlock code. This code is

available all over the place for less then $10.00. Just search

on theftlock. Use the HR and MIN buttons to enter the code

and you are in business.


This may sound a bit complicated at first but you can do it

in less then a minute with a little practice.


Theftlock II - Uses an EPROM (erasable/programmable

read only memory) or a PROM (the difference is you can

not alter the prom once it is programmed). In either case

the code is burned in and holds even when the power is lost.


With Theftlock II the radio is married to the vehicle by way

of the VIN. When the vehicle is started the computer

compares the number in the radio with the VIN. If they

match, the radio works, if not the radio displays LOC and

you are finished, there is no easy way around it. The radio

will not work until you make a trip to the dealer.


If the radio has an EPROM the dealer will use something called

a TECH 2 DEVICE to change the VIN stored in the Radio.

The Radio does not need to be removed (for the serial

number or any other nonsense). The technician just plugs

into the computer and resets the VIN in the radio. It can

be done (if you know how) in less then 15 minutes.

I checked around and the going rate is about $60.00

(none of the dealers I contacted would do it for free).

That works out to $240.00 per hour, but still much

cheaper then a new GM Radio.


If the radio has a PROM then the chip must be changed

and that seems to be factory only, in other words a new

radio! The good news is, only a very few of the high end

GM vehicles are equipped with a PROM so it is highly

unlikely that your radio has this anti theft feature.


Good Luck!

SOURCE: unlock code for delco radio in a chevy blazer

Try 0000 to unlock the radio, if the radio does not take any more codes you can reset the radio by disconnecting the battery and reconnecting it after 1 min. If 0000 does not work, go to radio-code.com. There is like $12.00 fee, but that's better then the dealer and you get to keep the code. Good luck

Locked infinity rsd radio in 2002 chevy venture


Does the radio say "LOC" or does it read "000"? Which AC-Delco radio do you have? Are there 5 or 6 pre-set buttons for selecting a station?

Did you consult your Owners Manual? There is a procedure the dealer can do to unlock the radio, but I know how to get the unlock codes for free.

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.
