A module which communicates on the class 2 serial data circuit which supplies VIN information to the radio is replaced and not properly setup with the correct VIN information for that vehicle.
The only way to unlock the radio is by using a scan tool. Always refer to the table in this section to diagnose the "Theftlock" DTC for further information.
So what problem are you having ?

The CTD system requests the IPC to illuminate the indicator only when the ignition switch is OFF. The CTD system uses the indicator in order to identify system status. For specific CTD condition that will illuminate the security indicator, refer to Content Theft Deterrent (CTD) Description and Operation .
The IPC performs the displays test at the start of each ignition cycle. The indicator illuminates for approximately 3 seconds.
SERVICE THEFT SYSTEM The radio illuminates the SERVICE THEFT SYSTEM message when the VTD system detects a failure. The radio receives a message from the theft deterrent control module via the serial data circuit requesting illumination.
This is one you need to take to the dealer , unless you have a GM factory scan tool !

The Content Theft Deterrent (CTD) System also contained in the BCM commands the instrument cluster to control the indicator only when the ignition switch is OFF. The CTD System uses the SECURITY indicator to identify system status.
It's software , a program inside the BCM ! An you can't just replace the BCM , it needs programming ! The dealer is the place to have that done ,most of the time ! If there is a SECRUITY light lit on the dash ,there is a DTC - diagnostic trouble code stored in the BCM , this code will point the service technician in the diagnostic path !
