Avital 3103LX 1-Way Vehicle Security System

The Avital 3103LX is a 1-way vehicle security system designed to add remote-controlled protection and keyless-entry convenience to a compatible vehicle. It combines arming, disarming, starter-interrupt capability, an impact sensor, and flashing parking-light confirmation. It is intended for drivers seeking a dedicated security upgrade rather than a remote-start system.

Two included 1-way, 4-button transmitters provide control from up to a stated 1/4-mile range. The remotes support lock/arm, unlock/disarm, panic, and auxiliary functions through a simple button layout. This makes the system suitable for everyday access and security control without relying on a factory key fob alone.

The 3103LX uses an impact sensor to detect vehicle impacts and includes Nuisance Prevention Circuitry to help limit repetitive alarm triggers from the same source. A starter interrupt adds a theft-deterrent layer, while Panic mode can activate the alarm for vehicle location or attention. When armed, the system uses horn and parking-light feedback as configured during installation.

Remote keyless entry and ignition-controlled door locks support a more integrated vehicle-security experience when connected to compatible factory door-lock circuits. The system also provides two auxiliary outputs for installer-configured convenience functions, such as an optional trunk-release application. Silent arm and disarm operation can temporarily suppress confirmation honks.

The Avital 3103LX is best used as a professionally installed security foundation for vehicles that need alarm, locking, and visual-status functions. Its programmable passive arming and valet mode add practical flexibility for daily driving and service visits. Installation should be planned around the vehicle's existing electrical, door-lock, trunk, hood, and lighting connections.

Key Features

• 1-Way Security System: Provides remote-controlled vehicle arming and disarming.
• Two 4-Button Remotes: Gives two users direct control of core functions.
• Up To 1/4-Mile Range: Extends remote operation beyond close proximity.
• Starter Interrupt: Adds a theft-deterrent layer against unauthorized starting.
• Impact Sensor: Detects impacts and supports alarm response.
• Two Auxiliary Outputs: Supports installer-configured convenience accessories and functions.

Design & Installation

The system is built around a vehicle-mounted security control system and two compact 1-way transmitters. Each transmitter has an internal antenna, a transmit-status LED, and dedicated command buttons for security and convenience functions. The design relies on vehicle-side visual and audible confirmations, including flashing parking lights and horn feedback when those circuits are connected.

Professional installation is required because the system interfaces with the vehicle electrical system and may be connected to door locks, parking lights, starter-interrupt circuitry, sensors, and optional auxiliary functions. Confirm vehicle compatibility and any required integration parts with the installer before purchase. Ask the installer to identify the Valet switch location and configure passive arming, lock behavior, and auxiliary outputs for the intended use.
