Thats a problem... the easiest way to unlock it is to hold the mute button. If it helps, i got mine unlocked by disconnecting the battery cable a few times

for 50.00 bucks go into your local dealership, its something that has to be done there.. I had the same issue putting my truck back to stock with a head unit from my other truck.
