Help with locked radio

[ck115]

Hello, I recently put an aftermarket cd player in my 04 grand prix gtp comp g, and had the stock monsoon stereo so i figured id try putting it in my sisters 04 grand prix gt. I put it in and all was well to start with, until my sister took the car for a drive and it said locked and stopped functioning. Is there any way i can unlock this radio, or is there a code or something from my comp g that i can type in to make it work? Thank you in advance for your help!

For these newer radios its a trip to the dealer to do a radio setup to relearn the vin in the radio to match that of the car, Prices vary between each so you can negotiate them since it only takes a minute. RPO code for the 6 disc is UC6, this will help them do it alot quicker when they go through the menus on the scantool.
Did it sound great thoguh even without the premium sound in the car before it locked?

Hello thank you all for your help! I guess ill have to make a trip to the dealer on Monday, and hopefully its cheaper than just putting in an aftermarket one. It didn't sound 2 bad without the premium sound, it was just lacking aittle bass. I'm surpised it worked at all though I just figured it would be worth it for the 6 disk changer. Thank you for all your help!
