You need to unlock the radio by putting in the code, if you aren't the person who put the code in the radio to begin with you can't unlock it yourself. If you are the person the car is registered to, you can take it to a dealer and have it unlocked. you may be able to call a dealer parts department and get some help, but you have to prove it's your car....a trip to the dealer will cost you some time and money, but if the radio works good, it's cheaper than buying an aftermarket radio to replace it.

2004 4WD Trailblazer didn't start this morning. No crank, no ticking but some power to accessories. My son tried to put window down and the radio came on. Later in the day, the radio came on...


I had the key stuck once. Make sure the key is in the off position. Make sure the steering wheel is not locked against a stop. The vehicle must be in park and try stepping on the brake. Try jumping the car with another car or battery pack.

Changed the radio in my 05 trailblazer and it says the radio is locked is there any way to unlock it. I have the Vin number to the car it came out of.


You have to call the dealer to retrieve the unlock code. Have the vin number for both vehicles and talk to the service manager. They should be able to assist you. Hope this helps. Good luck
