Overview
Arming and disarming the vehicle from a key-fob remote is the core of this Avital car alarm. Two remotes come with the system, and a siren sounds when the alarm triggers.
A simple one-way security kit and a long range are the reasons to look at it as a basic upgrade or a direct swap for an older unit. The limitation is the one-way link, which cannot report back, and the listing's very short feature set.
Who it's for
Drivers with a vehicle that needs a basic alarm, and shops swapping out an older system, can use the replacement kit. Buyers who want remote start or status reports from the car should look at higher models.
Pros and cons
- Two four-button remotes
- Loud listed siren
- Long range for a one-way remote
- Limited lifetime warranty
- Professional installation required
- One-way remotes give no confirmation
- Vehicle compatibility not listed
Performance notes
The remote sends commands and the alarm acts on them without reporting back, so the user cannot confirm arming from a distance. Range depends on obstacles and interference, and the listed distance is a maximum. The siren level is a rated figure, and actual loudness depends on where it is mounted.
