Avital 2103L 1-Way Keyless Entry System with Two Remotes

The Avital 2103L is a 1-way automotive keyless-entry system designed to add remote locking and unlocking convenience to a vehicle. It replaces the Avital 2101L and includes a control module with two 4-button transmitters. The system is intended for professional installation in automotive electrical systems.

This kit is suited to drivers who want remote door-control functions in a vehicle that does not already have them or needs an updated keyless-entry solution. Avital specifies that it can be used with virtually any vehicle, including vehicles without factory power door locks. Vehicle-specific wiring and hardware requirements should be verified by a qualified installer.

Its operating character is straightforward and command-focused, using 1-way remotes for lock, unlock, panic, and auxiliary-control functions. The remotes use internal antennas and transmit LEDs to indicate when a command is being sent. Transmission range is listed at up to 1/4 mile under suitable conditions.

The 2103L combines remote keyless entry with ignition-controlled door-lock capability and flashing parking-light confirmation. A panic/car-locator function can activate the siren and parking lights, while temporary audible lock and unlock confirmation can be selected from the remote. Two auxiliary outputs allow compatible optional vehicle functions to be integrated by the installer.

As part of a vehicle convenience upgrade, the 2103L can provide remote access functions without adding a remote-start feature. Auxiliary output 1 can be configured for an optional function such as trunk release, while auxiliary output 2 supports another installer-configured function. The included remotes are Avital part number 7147LS replacements when additional transmitters are needed.

Key Features

• Two 4-Button Remotes: Includes two 1-way Avital 7147LS transmitters for everyday vehicle control.
• Remote Keyless Entry: Lets you lock and unlock compatible vehicle doors remotely.
• 1/4-Mile Range: Provides listed transmission range of up to 1,320 feet.

Design & Installation

The 2103L is a compact black keyless-entry kit with a control module and two handheld 4-button transmitters. Each transmitter includes an internal antenna and a transmit LED. The listed product package measures 5 x 4 x 3 inches and weighs 0.85 pound.

Professional installation is required because the system must be integrated with the vehicle's electrical, door-lock, parking-light, and optional auxiliary circuits. An installer should confirm vehicle-specific lock configuration and determine whether additional hardware is needed for the desired functions. After installation, the owner should receive the two remotes and an Owner's Quick Reference Card.
