Overview
Starting the engine from a distance is the core job of the Avital system, alongside lock, unlock and trunk release on two remotes. A starter interrupt blocks hot-wiring, and a two-stage impact sensor chirps or sounds the alarm.
Long range remote start plus theft protection covers comfort and security in one kit. One-way remotes give no feedback that the car started.
Who it's for
Commuters parking within sight or a short walk get remote start and alarm features. Those parking far out of view may prefer a two-way system with feedback.
Pros and cons
- Long range remotes
- Two remotes included
- Phone app add-on compatible
- One-way, no confirmation
- Installation not described
- Vehicle compatibility not listed
Performance notes
Range depends on obstacles and interference between remote and car. The impact sensor reacts in two stages, warning chirps for light hits and the siren for heavy ones. The starter interrupt cuts the starter circuit unless the system allows it.
