Directed DB3 Databus All Interface Module

Get more control over your vehicle's security system

Many cars today feature an immobilizer security system that won't allow the car to start without first sensing the presence of a chip imbedded in the key or key fob. Directed's DB3 module tells your vehicle through its databus that it's okay for an aftermarket remote start or security system to start the engine or unlock the doors without that chip.

The Directed DB3 module works in even more vehicles than the original DB-ALL module or its successor the DBALL2, and is compatible with all Viper, Directed, and Python security systems, as well as most other brands.

Simplifies your security wiring

A single data-to-data harness connects your Viper (or other Directed) system to the DB3, so you don't have to hard wire your security system to a lot of door locks, solenoid releases, and other sensors — you'll save a huge amount of installation time. The DB3 module usually connects to your vehicle through 2 to 6 hardwired data connections, but we do carry some vehicle-specific T-Harnesses that make that connection much easier (call for details). Your DB3 will come pre-programmed for your specific vehicle, so you'll have total control over locking and unlocking doors, starting the engine, arming and disarming the factory alarm, and any other computerized function your vehicle can perform.

Even simpler installation for remote start-ready vehicles

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.

Important: If you know how to use a multimeter and have experience working with your vehicle's electrical system, you should be able to install this car security equipment. If you're unfamiliar with installing car security equipment, please speak to one of our Advisors before attempting this installation. Professional installation is highly recommended.

Note: You must identify your vehicle to order a Directed DB3 module online. Or, if you prefer, call an Advisor at 1-888-955-6000 to make sure you get the bypass module programmed for your exact vehicle.
