radio locked

Replaced the broken radio in my 2005 GMC Sierra with one from another truck. Radio says LOCKED, can this be removed, and if so how?

Re: radio locked

To unlock the radio you need to take it to a GMC dealer and they can use the factory scan tool to relearn the VIN number to the radio so it can unlocked.

The radio theft will learn the VIN. Without learning the VIN, the radio will display a locked message (LOC or LOCKED).
