[Edgar]

i bought a stock car stereo for my 00 impala b/c mine was just the radio kind, i installed the one i bought, and now its locked.
is there something else i can do to inlock it without having the chevy dealer unlock it for me?

try using the preset buttons and punching the code 4444 in it its uses a 4 digit code to unlock it with and those numbers have unlocked them a few times for me,you have to do it about 3 times in a row before it usually works when you don't have the correct code,it may or may not work but it only takes few seconds to find out,good luck.
