My radio is locked on my 2004 chevy aveo can you help me unlock this?

best solution is just repladce stereo. I lost my card with code on it that came with car upon purchase. The cost of placing code is as much as the replacement of new stereo with better quality, finctionability, and they are pretty cheap now. If you do it yourself don't forget to get replacement wire harness. best solution is just repladce stereo. I lost my card with code on it that came with car upon purchase.
