If your car came with an owners manual the instructions should be in there to unlock your radio. However if someone reprogrammed your radio with a code other then the factory code you may need to take your car into the dealer to have it reset. This will run you around $60. I hope this helps you out, and if you have any other questions please feel free to ask.

if it is a factory radio (head unit) i believe you need a code to unlock it. its something the auto companies started doing awhile back so when someone stole your radio they could not unlock it to resell it.

You have to check your owners manual. Your vehicle has to have the key in the one position for a certain amount of time. Most are for 2 hours to unlock the radio. Then when its unlocked you have to just enter the code to make the radio work. Make sure you keep the radio on during this time you have the key on.

Any GM car dealer can cut a duplicate key for your car for about $10. You have to show them a picture ID, and the car ownership (TITLE). This key, without the transponder chip, will let you unlock the car but won't start it. Just tell them that you need a plain car key, without the transponder chip.

CLOSE ALL DOORS INSERT KEY INTO IGNITION.DO NOT TURN THE IGNITION SWITCH.PRESS AND HOLD DOOR LOCK SWITCH IN THE UNLOCK POSITION.SWITCH THE IGNITION ON OFF ON OFF.RELEASE DOOR LOCK SWITCH.SYSTEM SHOULD NOW LOCK AND UNLOCK VECHICLE INDICATING PROGRAMMING MODE ACTIVATED.PROCEED AS FOLLOWS.NOTE EXISTING REMOTE TRANSMITTER MEMORY POSITIONS WILL BE OVERWRITTEN.PRESS AND HOLD LOCK AND UNLOCK BUTTONS ON THE FIRST REMOTE TRANSMITTER FOR 15 SECONDS.SYSTEM WILL LOCK AND UNLOCK VECHICLE INDICATING REMOTE TRANSMITTER PROGRAMMED.REPEAT ABOVE PROCEDURE FOR EACH REMOTE TRANSMITTER.IF THIS DONT HELP DEALERSHIP HAS TO REPROGRAM REMOTE.

The dealer will need to get the code to unlock the radio. How it works is they retrieve a code from the radio, thenthe code is called in to get another code to unlock the radio.

They will charge you for this. It usually takes about a half an hour.

Dealer can give you the code,call them with your vin number.

Replace the ECC 10ma fuse on the driver's side fuse panel.
This happens to me periodically.

Go to your local dealership with the VIN and they can look up your code. Write it down in your Owner Manual. There should be no charge for doing this.
