7 Best Car Alarm Features

Many car owners worry about their car’s safety and security today more than ever. This is a valid concern as the National Insurance Crime Bureau reports over 1 million stolen vehicles in 2022 — a number that hasn’t been reached in the U.S. since 2008. California, Texas, Washington, and Florida lead the nation with the highest number of motor vehicle thefts.

With a substantial rise in car theft, comprehensive security systems like the ones we at Compustar offer, protect your vehicle and alleviate the stress of being a car owner. Our advanced car alarms feature 7 important components that collectively work together to keep thieves away from your vehicle.

Control Module

Control Module

A remote start and security control module allows each part of a Compustar system to communicate with your vehicle. Much like the motherboard on a computer, the control module is the central communications hub on a Compustar system. The control module serves as a platform that connects all the individual remote start and security components to one another.

As an example, security sensors that detect vehicle impact or intrusion communicate back to the control module — signaling an alert to your 2-way Compustar remote. The control module also enables your remote to perform security and remote start functions on your car.

Bypass Module

Most modern vehicles are equipped with immobilizers designed to prevent a car’s engine from starting without the factory key — making cars less vulnerable to theft. A bypass module acts as a bridge connecting a Compustar remote start and security system to your vehicle. The bypass module needs to be programmed or “flashed” with vehicle-specific firmware for the remote start and security system to properly send commands without the physical presence of a key

When it comes to security, a bypass module makes remote start possible while enhancing your car’s factory alarm features. Compustar’s advanced security sensors can be safely added to your vehicle without disconnecting any of the original factory anti-theft features with the use of a bypass module.

Security Sensor

Security sensors are essential to car alarms. After all, what’s the purpose of a car alarm if your vehicle can’t detect harm?

When paired with a Compustar 2-way LCD remote, the DAS-II 4-in-1 security sensor will notify you of any threats to your vehicle. The DAS-II features 4 security sensors that detect:

  • Impact/Intrusion (2 stages)
  • Tilt
  • Forward Motion
  • Glass Breakage

In addition to vehicle security, the DAS-II is a requirement for safe installation of remote starters in manual transmission vehicles. If you remote start while your vehicle is left in gear, the DAS-II will automatically halt your engine if forward motion is detected.

Alarm Siren

Alarm Siren

One of the first components that come to mind when it comes to car security is an alarm siren. Most factory car alarms simply use the vehicle’s horn when your doors are forced open while your car is locked. A Compustar security system adds a loud 105+db siren that alerts anyone in and around your car’s vicinity.

What makes our siren unique is that, unlike a traditional car alarm, a Compustar siren is paired with our 4-in-1 security sensors like the DAS-II. This means that the siren will blare when impact, tilt, forward motion, or glass break is detected. On top of that, Compustar installers will typically place the siren at its loudest position inside your vehicle — giving anyone who breaks into your car a terrible experience.


As its name implies, an engine starter-kill relay, or “E-LOCK” relay as we like to call it, prevents your engine from starting. When your Compustar security system is armed, this component safely disables your car’s starter until you disarm the security system from your remote.

Adding a starter-kill to your vehicle is one of the best solutions for eliminating car theft. Even if a thief manages to get inside your vehicle, they won’t be able to start the engine until the Compustar security system is disarmed.

2-Way Remote

2-Way Remote

An effective security system isn’t complete if you aren’t notified when your car is in danger. A 2-way Compustar remote with alarm alerts solves this issue by signaling when your car alarm is triggered. Compustar remotes featuring 2-way alarm alerts communicate with the other security components on this list to notify you of any harm caused to your vehicle while you’re away.

Compustar’s LCD remotes can send commands and receive alerts from great distances. Our PRO T13 and T12 remotes have a max range of 3 miles — giving you plenty of security coverage. These 2-way LCD remotes give off distinct chirps, vibrations, and eye-catching animations to let you know exactly when your car may be in danger.

Smartphone Control

If you want even more range and security out of your car alarm, then DroneMobile is exactly what you’re looking for! Many Compustar security systems come bundled with a Drone X1 LTE module for fast smartphone car connectivity. DroneMobile allows you to stay connected to your vehicle from anywhere with your smartphone with the DroneMobile App.

DroneMobile gives you unlimited range vehicle control, security, and the additional benefit of GPS tracking with a Premium DroneMobile subscription plan. Similar to a 2-way remote with alarm alerts, you’ll receive alerts regarding your vehicle’s security, directly to your smartphone via push notifications.
