Chevy Colorado radio

Question

I just put a Isuzu radio in my 2005 Chevy colorado when i turned my car on the radio said "LOCKED" and it didn't work

so i was wondering how to take the locked of my radio and use it again

Answer 1

locked means there is a code U have to punch in to get it to work aka anti-theft (U did'nt steal it did U) lol  u will need that isuzu radio manual book (should be in there) or contact isuzu/w the radio specs. or contact chevrolet for the same,,,or U can just punch-it,,,
