What the Avital 3103 system provides

The Avital 3103 is a one-way car security system that adds remote keyless entry and a built-in impact sensor. It includes two four-button transmitters for arming, disarming and panic functions. The kit is designed for vehicle owners who want factory-style door-lock control and a starter-interrupt immobiliser without two-way communication. Professional installation is required by the manufacturer.

How it integrates with the vehicle

The system connects to the vehicle wiring to provide ignition-controlled door locks and flashing parking-light confirmation. A six-tone siren and the impact sensor plug into the control module for audible and shock-triggered alerts. Starter interrupt prevents the engine from cranking while the system is armed. No additional sensors or transmitters are included, so features such as trunk release or window automation need separate modules.

Behaviour during extended use

The one-way transmitters send commands without receiving status feedback, so the user cannot verify arming state from a distance. The impact sensor triggers the siren on detected vibration, while panic mode activates the car-locator function. Because the system relies on the vehicle battery, long-term parking without driving may drain the battery if the alarm triggers repeatedly. The starter interrupt remains active until the system is disarmed with a valid transmitter.

Questions about this item

What is the first limit you hit when the 3103 siren sounds continuously?

The six-tone siren runs until the battery drains or the panic button is pressed again; there is no built-in timer to stop it automatically.

How much current does the 3103 system draw while armed and monitoring all day?

Quiescent draw is low milliamps from the vehicle battery; the impact sensor and control module stay active without measurable heat or noise.

Which vehicle circuits must already be present for the 3103 to lock doors and cut the starter?

You need factory power door-lock actuators and an accessible starter wire; the system taps those to provide keyless entry and starter interrupt.
