Anti-Theif

Hey does anyone know the master code for the anti-theft device on teh radios? My dad is a used car dealer and we get a lot of car that the radio is locked on so we have to take it to the dealership and pay $25 to have them unlock it... and all they do is put in some master code. so knowing it would be a big help..

There isn't a master code, you have to pull a 6 digit code from the radio itself and then call an 800 number and read that code to them. Also, the 800 number requires a dealership code. It is all automated, so if you have the numbers it is easily done. I had the same problem, and here is that thread:
