The reason the radio won't work is because of theft deterrent stuff built in radios now where if power is unhooked from the battery, you have to enter a code to get it unlocked. I would start by looking at your owners manual to see if there is a paper or page that would give the code you need to press to unlock it. If no luck there, I would go to the nearest GM dealer and tell them what happened and they should help you out and most likely not charge you anything.

Good luck

My girlfriend has a 2001 GMC Jimmy with a stock radio/cd player. after having the battery changed, the radio says loc and she is unable to "Unlock" it according to the manual. is there a trick? thank you...

you have to contact GM to get the unlock code which u can find online, just go to and they can help, it costs $7.95 or call your local gm dealer but they will probably tell u to come in and overcharge u!

Radio unlocking

the specific instructions are in the manual that came with the car, there is a code required, if you dont have the manuals or the code, a chevy dealer can look it up on the service computer for you,. assuming they are nice people ! they might even do it for you.
