Theftlock

How do you unlock & lock the theftlock on a 2004 Silverado with the EM,CD,tape options. I just got my truck and want to unlock the system so i can work on it.

Here are the RPO's UB1,UE1,UK3,U2K.

Welcome to the forum. On the 2004, you don't have to do anything to lock or unlock the radio. The radio checks against the VIN number on the vehicle it is originally installed and unlocks itself as long as the VIN numbers match.

Thanks carguru,

I had a bad experence with my Grand Prix. It had a code in the radio when i got it from GM and when it was time to change the battery the radio wouldnt work. I didnt want the same to happen with this truck. My 2001 didnt have the theftlock radio..

Thanks again.

Anytime. On the full sized trucks, they changed the radios in 2003. On the 2001, it should have had a theftlock radio. Maybe it was not set. The radios were pretty much the same from '95-'02.

My 01 Silverado was an "LT" also and had the CD & Tape but no XM and it didnt have the theftlock. I checked when i got it to make sure and disable it but it didnt have it.

Anyway i sure like the XM radio in this truck. Infact the changes between this truck and the 01 is amazing considering they are option wise the same except for the XM and ride control.

Your 2001 should have a radio like this. It does have theftlock. For these, you have to set a code in the radio to activate theftlock. If you didn't set the code, the blinking light doesn't come on.
