Unlock code for delco radio in a chevy blazer

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.

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.

try code 0000, this is the stock code, unless someone has changed it. also you can go to www.radio-code for info on all codes.

are u the original owner of the car ?if so do you still have the books that came with the car? look for the delco radio book !there should be a card in there with a code and instructions! if not the only wasy is to go to the dealer or a radio repair shop to have it unlocked!

You will need to take it to your local dealer for them to pull code and call Delco for the unlock code,This usually takes about 10-15minutes.Make sure they give you the unlock code so you could use it for that radio if you lose power to it .

shouldnt have to pay notify a chevy dealer in person for code most dealers wont deal with a code problem over phone they dont charge for the code due to the fact that a dead battery can also lock out the radio system into the anti-theft mode

check in your owners manual for radio lock and unlock code or local dealer,assuming thats your question

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.

I've heard of people using Delco Lock Codes (http://www.delcolockcodes.com) to get their radios unlocked. They seems like a legit site from what I've read. Good luck!!
