Buying Guide for the Best Car Alarm System

One of the best things you can do to secure your car is by installing a car alarm system. You need a unit that is reliable and has convenient features to foil any car theft.

Hunting for a good car alarm system can be frustrating, especially if you don’t know the exact feature to look for. There are plenty of choices in the market, all promising to deliver quality protection.

Below are the key factors you need to consider while buying the best car alarm system.

Compatibility and Ease of Installation

Not all car alarms in the market are compatible with every car brand. However, the good news is that most of them are compatible with cars that have a 12-volt system. Before making any purchase, confirm the compatibility of the alarm on the manufacturer’s website.

As for the installation, go for an alarm that doesn’t have a lot of complications. If you are conversant with the car electrical system, you can do the alarm installation yourself.

Alternatively, you can seek professional installation from your local mechanic. Installation of alarm systems is better in the hands of an expert because simple mistakes can foil your car warranty.

Alarm Range

Most car alarm systems claim to have a mile-long range. Though this sounds great, you hardly need to start your car while a mile away.

Therefore, think of the alarm range in terms of the signal strength instead of distance. In your shopping spree, it is recommendable to buy a car alarm that has a responsive and robust signal. It may not be in the high range category, but it is worth it.

Alarm Noisemaker/ Shock Sensors

It is the most basic feature of a car alarm system. The alarm noisemaker is the one that sounds when someone tries to break into the car. The noise draws attention to the car and scares away car thieves.

It is recommendable to go for quality shock sensors because they determine the effectiveness and sensitivity of car alarm systems. The sensors should sound an alarm anytime someone breaks through the glass or hits the car with a great impact.

An ideal alarm system should produce 100 decibels of sound or more to deter car thieves. The higher the decibels, the louder the alarm siren.

Car Jack Protection

It is almost similar to the shock sensors. However, not all alarm systems come with car jack protection.

This feature includes high-pitched sirens, chirping alarm, or an ignition kill switch. It works incredibly well in deterring car thieves.

Two-Way Pager/ Remote System

A two-way remote control system can send and receive signals. As such, you can activate or deactivate your car’s alarm via a remote, and also you can receive information from your vehicle to the remote.

A two-way alarm system is more appropriate in areas that have high crime rates. It gives you real-time notification on any attempts to break into your car. Also, it gives you visual feedback when your car’s AC or engine is turned on.

High-end models of a two-way pager are customizable in that they can give you specific security alerts.

Encrypted Transmissions

We are living in a digital era where we have tech-savvy car thieves everywhere. As such, having an encrypted transmission is a huge bonus to your car’s security system.

Usually, tech-savvy thieves use state-of-the-art hacking equipment. With this, they can access the signals sent between your car alarm system and your remote.

With an encrypted transmission, it’s only your car system that can decode the signals sent by your remote and not any other device. This feature allows the alarm system to differentiate genuine remote signals from those of a hacker.

Smartphone Compatibility

Presently, many manufacturers are integrating their car alarm systems with smartphone apps. This feature allows car owners to control their cars directly via their smartphones. In case of a security breach, some of these features send you alerts via text or mail.

The GPS tracking feature on your phone can be incredibly helpful in case your car gets stolen.

Keyless Entry

Keyless entry is an incredible, must-have vehicle security feature. It allows you to unlock the doors of your car by one click of a remote button.

Also, it is inter-linked with the alarm system to allow you to lock or unlock your car doors without a key.

The Brand

There are tons of alarm system brands in the market. Reputable brands that have been in the industry for a couple of years consistently delivers quality products. Most of them offer professional installation when you buy from their main branches.

Going for such manufacturers can save you hours of research and wrong guesses. However, this does not mean that lesser-known brands produce low-quality products.

The most recommendable manufacturers for car alarm systems are Python, Avital, and Viper.


A car alarm system is one of the most important investments you will ever make. As such, avoid going for the cheapest sets because they may have compromised quality.

Average alarm systems range between $50 and $200. When deciding on the pricing to go for, check features such as shock sensors, smartphone integration, the strength of range, performance, and reliability.

Number of Acceptable Remote Transmitters and Receiver Channels

All control functions of a car alarm system, including remote transmitters, pass through the receiver.

Each receiver has a certain number of channels. A receiver that has more channels can perform more external functions and vice versa. These functions include:

  • Car remote start
  • Trunk release
  • Locking and unlocking doors
  • Automatic window roll-up
  • Car location
  • Immobilizer

We recommend buying a car with a receiver that accepts as many channels as possible.
