4. Setup and Installation
Professional installation is highly recommended for the Viper 4105V system. This product requires detailed knowledge of 12V electrical wiring and vehicle-specific wiring diagrams. Installation involves working with the underside of the vehicle's dashboard and under the hood.
Some vehicles may require additional parts, such as transponder keys or data-based door lock systems, for full functionality. Consult with a professional installer to determine if your vehicle requires these additional components.
4.1. Flashing a Bypass Module (if required)
If your installation requires a bypass module (e.g., Idatalink BLADE), it may need to be flashed with vehicle-specific firmware. The following video demonstrates the general process for flashing a Compustar Blade module, which is similar for other Idatalink bypass modules compatible with Viper systems.

5. Operating Instructions
The Viper 4105V system provides convenient control over your vehicle's remote start and security functions using the included 4-button 1-way transmitters.
5.1. Remote Start
To remotely start your vehicle, press and hold the remote start button (often indicated by a circular arrow or 'S' button) on your transmitter for approximately 3 seconds. The vehicle's parking lights will flash, and the engine will start. The system is designed for automatic transmission vehicles only (fuel-injected, diesel, and hybrid).
To turn off the engine after remote starting, press and hold the remote start button again for 3 seconds.
5.2. Lock and Unlock
Press the LOCK button once to lock your vehicle's doors and arm the security system. Press the UNLOCK button once to unlock your vehicle's doors and disarm the security system.
5.3. Auxiliary Functions (Trunk Release, etc.)
The system includes two auxiliary channels that can be programmed for additional functions, such as popping open the trunk or lowering windows. Consult your installer for specific programming of these channels.
5.4. Car Finder / Panic Mode
To activate the Car Finder feature, which flashes the vehicle's lights five times slowly, press the designated button (often the lock button multiple times or a specific auxiliary button). For Panic Mode, which sounds the horn (if connected), press and hold the panic button (often the lock button for an extended period or a dedicated button).
5.5. Demonstration Video
The following video demonstrates the remote start, lock, unlock, and trunk release functions of a Viper system. While the remote shown may be a 2-way model, the core functionality for remote start and keyless entry is similar to your 4105V system.
