The DS4SU Security Upgrade Kit lets you add security and alarm protection to a compatible DS4 or DS4+ remote start system. It is built to create a more complete system for everyday vehicle security and convenience by adding a 6-tone mini siren and a shock and tilt sensor for impact and lift detection. Enable the security functions during programming, then fine-tune the setup for the vehicle and customer needs.
