Prevent Car Theft
Firstech adds an extra layer of protection to your vehicle's ignition system by temporarily disabling it while your alarm is armed. So even if a car thief steals your factory key or attempts a "relay attack", they won't be able to drive your car without your Compustar remote.
To enable this feature, ask your Compustar installer about "Starter Kill" and "Secure Push-to-Start".
Upgrade Your Vehicle Security
Unlike most factory car alarms, Firstech'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 remote if your car alarm is triggered.

Remote Start Upgradable
Not all vehicles are capable of having a remote starter installed. Listed pricing is for most vehicles. Some vehicles require additional parts & labor. Please call for an exact quote.
