How to unlock 2006 chevy uplander radio when it say “locked”

SOURCE: my 2005 chevy cobalt factory radio is locked

There are only 2 things you can try to fix this yourself: turn off the engine and open the driver side door (to turn the radio off). Wait 5 minutes, start your car.
If that does not solve it, turn off your engine, disconnect the car battery, wait about 5 minutes. Reconnect the battery (negative pole first - black connector) and try your radio again.

If neither one of these two fix your problem, I am afraid only a GM service center or dealership can fix the problem. The Cobalt is notorious for all kinds of electrical issues.

Thanks for using the fixya forums!

2 possible solutions. First clean the door pin contacts(multiple spring loaded pins on door side and matching plate on body) with a scotch pad until shiny gold color again. Second the rear edge of the door should be 1mm inside the body opening when closed. If those are correct it is going to take a software download from a dealer to the door control module to fix this. Otherwise you will have to pull the psd fuse and breaker from the right side dash fuse box.
