#1 in Vehicle Security
Compustar helps millions of drivers detect, deter, and prevent vehicle theft with our advanced security systems.

Upgrade Your Vehicle Security
Unlike most factory car alarms, Compustar's advanced security systems protect your entire vehicle by detecting threats to your doors, windows, and engine. In tandem with our theft-deterrent siren, you'll receive alerts from your 2-way Compustar remote if your car alarm is triggered.
Even if a thief manages to get inside your vehicle, our engine starter-kill relay will prevent your car from starting until your Compustar security system is disarmed.
