4003L Avital Avistart Remote Start Module
Add the convenience of Avital remote start to virtually any remote system – OEM or aftermarket – using the remotes you already have to activate remote start.
Have you been looking for the Valet 561T & can't find it? That's because it was discontinued last year.

In fact, the entire "Valet" line was discontinued. The Avital 4003L is the replacement model, made by the same manufacturer - Directed Electronics
Many vehicles require an interface module for system installation. With our XpressKit line, modules are available for most vehicle makes and models.
In addition, most newer vehicles control power door locks and anti-theft or security features by sending digital signals over a network called a databus. By interfacing with this databus, your new Viper system can control factory features – right from your Viper remote! See Our Interface Modules
