Things To Know Before Buying a Car Alarm

Everything You Need to Know Before Buying a Car Alarm

There are approximately two million cars stolen every year. With this statistic, there is no reason to postpone buying a car alarm. This device or car accessory will not only protect your vehicle from thieves but will ultimately protect your family, livelihood, and other investments.

However, there is one problem often faced by consumers when buying a car alarm. That is the problem of choosing which type or brand of car alarm they should invest in.

If you are here because you want to find the perfect car alarm for your vehicle, then you have found the right page.

Different Types of Car Alarm

The first step in your search for a car alarm is to understand the difference between each type that is available on the market. There is a long list of products from high-end car alarms to less expensive models waiting for you when you type “car alarm” into the search bar.

There are many ways to choose a car alarm based on added features and enhanced functionalities. Aside from this, many car alarms also fall under several categories. The following are just some of the different types of car alarm.

Passive Car Alarms

One of the best things about passive car alarms is that there is no need for user intervention. You can leave your car, lock the doors and be at peace.

You don’t even have to remember whether or not you have switched the alarm on. This is because you do not have to turn it on or do anything to activate it.

Passive car alarms are automatically activated whenever you lock your car. However, one obvious limitation of this type is your lack of control over the system.

Since there is no user intervention whatsoever, you do not have access to some of its features such as the chips used in the keys for disabling the ignition if you mistakenly used a wrong key.

Nevertheless, the straightforward passive car alarm is still good enough for many car owners.

Active Car Alarms

This type of car alarm is common nowadays in modern cars. It heavily relies on user intervention when it comes to activating the system.

Unlike the passive alarm, you cannot just lock the door and walk away because that won’t activate the alarm.

Clearly, this kind of alarm is not ideal for forgetful car owners. Therefore, activating it every time you have to leave your car should become a reflex.

On the other hand, many people still prefer this type because of the control and access to additional functions it offers.

Remote Start Car Alarms

As the name suggests, the added functionality of this type of car alarm is the ability to start your car from a distance. This is possible because car alarms have always been wired to car ignition systems ever since the first versions in the 1920s.

This car alarm is also classified under the active category, but you may also found passive remote start car alarms. Remote start car alarms bypass the ignition lockout systems and are able to operate the locks independently. This will secure the vehicle and keep it locked until the owner reaches it.

Two-Way Paging Car Alarms

This alarm is one of the most sophisticated car alarms that can effectively deter thieves in two ways. The communication happens between the car alarm and the fob of the driver’s key ring.

Despite being expensive, many car owners prefer this type because of the higher level of security it provides. A two-way paging car alarm alerts the driver when an intruder breaks into the car by creating a loud, constant noise. Thus it draws attention when someone tries to open your car door.

Indeed, it is more effective than other types that can only flash the headlights. Aside from this, it can also notify the driver when the car alarm suddenly goes off when you did not deactivate it yourself.

GPS Car Alarms

GPS car alarms are not a standalone type. Rather, GPS is an added functionality that helps the owner locate his or her stolen vehicle. This is not a common feature, perhaps because it is not focused on preventing the car from getting stolen.

Still, it is very useful in assisting the police in recovering your vehicle. GPS allows you to search for the car’s location online or receive a text message containing its location.

Silent Car Alarms

Silent car alarms have both advantages and disadvantages. Car owners buy them because they reduce the number of complaints about alarms being too loud. Instead of making a noise, these car alarms send a silent message to the owner when someone breaks into the car.

On the other hand, is they are less effective when it comes to raising the alertness of owners and bystanders. For this reason, they are less popular than the other types.

Basics Functions and Advanced Features

The best car alarms possess the basic functions as well as cool additional features. For example, the simplest kind of car alarm is made with a sensor that is wired to a siren.

In the early years, this system was often attached to the driver’s door so whenever someone tried to break in, the sensor would signal the siren, causing it to sound.

As cars have evolved, so too have car alarms. There are now more advanced features that were not just invented to entice the public but also to increase the level of security. Some of these additional functions are:

  • Detecting motion by adding motion sensors, switches, pressure sensors, and more
  • Allowing drivers to pick from a variety of sound or siren options and choose a distinct car alarm sound
  • Remotely control the car from a key fob through a radio receiver
  • Switching from main battery to an auxiliary battery to continue operation when the main source gets disconnected

Factors to Consider When Buying the Right Car Alarm

Most car alarms today are intelligent and easy to handle. They offer sophisticated options to level up your security inside your car or away from it.

That is why it pays to consider which of the features you want to be present in your car alarm. Below are some of the factors to consider before you purchase one.


Car alarms are designed to go off whenever the driver’s door is forcefully opened. But that leaves three or more doors for the thieves. Because of this, you should choose an alarm that will go off when any of your doors are opened.

Aside from this, you might also want to purchase an alarm that comes with an impact sensor that triggers the alarm when the trunk of the car is forcefully opened. A glass break sensor that signals the alarm once it has sensed a window breaking is helpful too.

Remote Control

Remote controls for car alarms provide a keyless entry system. They can lock the door and activate or deactivate the alarm with just the click of a button.

Another good thing about having a remote control is the panic button. The panic button comes handy for many situations for example when you cannot find the car in a busy parking lot, or to prevent home invasions.

Modular Options

A good car alarm is easy to install in your car, but the best kinds of car alarm are customizable. In another term, they are modular.

You should be able to pick the features that you need and install them all at once or uninstall them later on. This way, you will know which one is more effective or important than the other. It saves you money, too.
