Need help with RDS gm radio
 

I have a buddy at work whos cd player took a crap.
He paid me I bought a radio off ebay, I put it in.

Radio has theftlock activated on it and from what iv read basically his 04 trailblazers(gm radios in 02+) can only be unlocked by a gm dealer or some one who works for a dealer with the GM Tech 2 Scanner, I heard it takes 2 minutes to do but the dealers charge damn near 75 bucks to do it!

If any one has a buddy or them selves works for a dealer and wouldnt mind helping me out by unlocking my buddies new radio we would both really appreciate it and wouldnt mind throwing you a few bucks for the effort.
