General Features

Remote Start

The remote start system supplies the vehicle with power and simulates a start just as if you were inside using the key. Select vehicles require additional accessories or immobilizer/bypass modules to use the remote start feature.
Keyless Entry
Keyless entry allows you to remotely lock, unlock, and open the trunk of a vehicle if that is equipped with power door lock motors (actuators) and power truck motor (solenoid). Door lock controls via the remote are found on nearly all of today's car alarms.

So far so good! Got my car broken into before I had it, now thieves see the bright blue LED from far off and know not to bother! Even if they tried I'm alerted right away. LOVE the extra channels. Integrating my power windows plus some special extras. There's a LOT you can do with this system, it's extremely versatile. No hassle there though, I'd definitely consider this when looking to protect your vehicle.
