Theft Deterrent Module Programming and Setup
WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
The theft deterrent module only acts as an exciter and antenna, energizing the key transponder and receiving the key code information. Because the immobilizer software is contained in the BCM, the theft deterrent module requires no programming or setup after replacement.
