Viper 3105V 1-Way Car Alarm and Keyless Entry

The Viper 3105V is a 1-way vehicle security and keyless-entry system designed to add remote-controlled protection to compatible vehicles. It combines arming, disarming, panic operation, door-lock control, and alarm responses in one system. This is a practical choice for drivers who want a traditional security upgrade without a two-way remote display.

The system uses two included four-button remotes for everyday lock, unlock, panic, and auxiliary-channel commands. Its one-way design sends commands from the transmitter to the vehicle, while the vehicle communicates status through siren chirps, parking-light flashes, and the status LED. A Revenger soft-chirp siren provides audible confirmation with a six-tone response character.

For security coverage, the 3105V includes an onboard dual-stage shock sensor, door-trigger inputs, an instant-trigger input, and ignition monitoring. The system can provide warning and full-alarm responses depending on the trigger source and programming. Its FailSafe starter-disable circuit is intended to help prevent unauthorized starting when properly installed.

The Viper 3105V is suited to vehicles needing security and keyless-entry functions where factory equipment is limited or where an existing system requires replacement. Auxiliary outputs can be configured for supported relay-driven functions such as trunk release or other accessories. An optional external sensor can also be added through the dedicated sensor harness connection.

This alarm can serve as a foundation for a larger vehicle-security installation. Its wiring includes door-lock outputs, parking-light control, dome-light supervision, and programmable auxiliary channels for integration with compatible vehicle circuits. Professional installation is recommended because correct vehicle-specific wiring, relay use, and sensor adjustment are essential to safe operation.

Key Features

• 1-Way Remote Control: Included remotes send lock, unlock, panic, and auxiliary commands to the vehicle.
• Three-Channel Design: Supports security operation plus two programmable auxiliary-channel outputs.
• FailSafe Starter Disable: Helps interrupt the starter circuit when the armed system is properly installed.
• Dual-Stage Shock Sensor: Built-in adjustable sensor can provide warning and full-trigger responses.
• Revenger Soft-Chirp Siren: Six-tone siren provides audible arm, disarm, and alarm confirmation.
• Keyless Entry Outputs: Low-current lock and unlock outputs integrate with compatible power-door-lock circuits.

Design & Installation

The system centers on a compact control module with an integrated adjustable dual-stage shock sensor. A separate windshield-mounted Control Center combines the antenna, status LED, and valet/program button for a clean, centralized installation. The included siren, harnesses, remotes, and control-center cable support a complete basic security-system installation.

Installation requires vehicle-specific connections for constant power, ignition, ground, siren, door triggers, parking lights, and door locks. Low-current outputs must drive relays or compatible low-current inputs rather than motors or solenoids directly. Mount the Control Center high on the windshield with its cable fully extended for remote range, and have the system installed by a trained professional.
