Ok, here is the situation. Helpful input/advice from anyone would be appreciated.

Just bought the wife an 02 Chevy Trailblazer. It has an OEM CD player. Both ***** on the radio were broken. Found and purchased a used OEM radio from someone on Ebay .($35!!!). I have a feeling it is going to "lock" once I turn the truck on after installing it. Is there a "simple" way to reset this radio once I get my hands on it without having to go to dealer?

It is GM Part # 15195521

Thanks.

yes. there is a theftlock procedure somewhere..............

oh BTW you can search google but there are some procedures that dont work

nope, you have to go to the dealer. the lock came on with my dad'* chevy truck, and i had to take it to the dealer to get it unlocked.

mremer when you get the radio write down the model # and serial number, the dealer should be able to give you the code to unlock the radio. Good luck

im really good friends with the service manager at my local chevy dealer when u get the radio let me know. I can help you if you need it.

thanks everyone; I'll touch base with choppers after I get the radio.

Thanks!

Mike

Ok, I installed the new radio. Put the key in the ACC position and the radio worked fine. Started the truck up and BAM "LOCKED". So I decided I would go to the Chevy dealer in my area to get it unlocked, then I was struck with an epiphany. The only thing wrong with the original radio was the face was all smashed in (loose *****, buttons missing/broken, and no back light). I swapped parts. Everything works fine now and NO trip to dealer!

Thanks everyone for you help.
