The DB3 is an all-in-one door lock and override module that covers over 90% of cars on the road today. It will support legacy systems like VATS and PASSLOCK as well as support door locks and override on the most modern of cars like Toyota with push-start ignition system and Chrysler with electronic ignition. The DB3 offers the most advanced hardware architecture in our industry and covers more cars than any of our competitors.
 
Many vehicles are remote-start-ready. If you own one of these, you probably won't even need a separate remote start system — just use a Directed DB3 and a T-Harness (if available). To activate the remote start, you'll need to press "Lock" three times on your factory remote. For extended range, add a Viper SmartStart module to control your vehicle remotely by smartphone.
