Car Alarm Buying Guide

The modern car security systems offered on the market today are very powerful, providing intelligent and sophisticated options. As a probable buyer of such equipment, it is wise to equip yourself with accurate information, surrounding this product. By doing so, you’ll determine the exact model and features you’d want in protecting your car. So, here are the major factors to consider when buying alarm systems.

READ: Pyle PWD701 Vehicle Security System Review


While many car alarms tend to go off once the driver’s door is opened, there are models that go off if any of the doors is opened. An impact sensor is a very good additional feature to such systems, triggering the alarm when someone tries to break in the car or the trunk.

This option is wise to install in the most vulnerable areas, allowing the glass break sensor in triggering the alarm once it senses a breaking window. A radar sensor, on the other hand, makes use of radar both outside and inside the car so as to detect movement, and such an option is independently adjustable.

Thief Thwarts

Another thing to consider will be thief thwarts or a door deadlock that stops the car doors from being opened. While thieves try to find their way through your car illegally, this helpful feature will surely thwart a thief. Perhaps, you might want to consider getting dynamic codes that change constantly, frustrating the thieves to use a code grabber.

The best car alarm systems may also offer a driver-side priority function, integrating a biometric fingerprint reader that only allows the owner or driver of the car to start it.

Remote Control

Of course, the remote control is a top priority. Having a keyless entry system, such as the reviewed products above, will let you enjoy the utmost convenience like locking and unlocking the doors, setting the alarm, deactivating the alarm, and so on.

It offers a panic button, which is very useful in busy parking lots and other emergency situations. It is also wise to have a remote with auxiliary channels that allows you to add optional sensors.


The interface is primarily the go-between for the new and the factory security system. The interface communicates with your vehicle’s computer, allowing you to perform some customization with it. Optionally, the immobilizer feature lets you shut down the ignition once the alarm goes off.

Moreover, the interface module lets you eliminate hours of installation, resistors, and relays. Modern interfaces allow you to install them on different vehicles, giving you control over factory-installed systems.

Remote Start

The best car alarm features a remote start, offering the utmost convenience to any car owner. This feature also requires installation and integration with the entire alarm system. The remote start also lets you configure it with your Smartphone for added comfort and convenience. Modern models allow you to use your Smartphone in starting your car or finding it within a certain range. However, make sure that the model is compatible with your Smartphone device.

The range is also a top priority when shopping for top car alarm systems. It is a very important factor, and choosing the longest range is always the best option. To date, the farthest range of security systems offers a maximum of one-mile, an impressive feature that surely gives you optimum convenience, regardless your location or your car’s location.

Automatic Rearm

The auto rearm option functions for a certain period of inactivity, rearming the car automatically in case you forget to set the alarm. Hence, this feature is significantly helpful for forgetful people.

Ignition Controlled Locks

Once the ignition is activated, the system will lock the car doors automatically. Such option in alarm systems prevents car jackers and thieves from taking over your car, keeping you safe, while moving or parked.

Trunk Opener

Functioning as a keyless entry system, a car alarm may also be used in opening the trunk of your car. It offers convenience and protection to whatever it is stored in the trunk without having to use your car keys or manually opening the trunk through a button inside the vehicle.

Car Finder

The car finder option lets you push a button through the remote, triggering your car’s alarm so as you can find its exact location. While it is not a necessity in most cases, this feature can still become useful in certain circumstances. This feature is most useful when you parked in a crowded or public space, especially when there are lots of identical models as your car.

Alarm Type

Depending on your personal choice, you can choose between two types of alarm system for cars. These types include the passive and the active type, whereas, passive alarms tend to activate automatically once the car doors have been closed and the engine has been shut down.

Active alarms, on the other hand, require you to manually arm the entire system. While both types can be effective, choosing a passive system offers wide ranges of benefits, convenience, and additional options.


Over and above, you should examine all the available options of auto alarm systems on the market. It is sensible to identify your needs or preferences, while searching for such car equipment. It is also wise to read about product reviews and descriptions, taking note of the product’s customer ratings. By doing so, you will have an adequate idea of the most reliable tools, based on the experience of actual users.

In a nutshell, car alarm companies are now offering consumers with high-performance and versatile security systems, meeting the needs and requirements of every car owner in protecting their vehicles from burglars, thieves, or carjackers.
