You want what any parent wants: to keep your family safe. With the best car alarm system, you can keep your property and family safe by deterring thieves from your home and vehicles.
Advancements in technology have led to some of the most convenient perks, and we’ll show you exactly what to look for in the best alarm for your car.
Below, you'll find some of the most commonly asked questions about car alarms.
What Does a Car Alarm Do?
Car alarm systems won’t prevent thieves from getting into your car or stealing your valuables, but it will deter people from doing so.
The added work that goes into getting around an alarm is often enough to keep thieves at bay, and the sound scares them away quickly before they can spend too much time snooping around your property.
Will Having a Car Alarm Lower My Insurance Costs?
Insurance companies vary, but many will give you a lower premium if you install a system they've deemed worthy enough.
What Are the Main Types of Car Alarms?
There are three main types of car alarm systems, and they vary based on how they work. Audible alarms are the most basic, with a sensor that triggers a loud siren if your vehicle is disturbed.
These are the cheapest types of systems, and sometimes a gust of wind or rowdy cat can set off the alarm.
Other alarms include:
What Convenient Features Should I Look For?
Car alarms some with various features, such as a remote start function, real-time security alerts, car finder, or smartphone compatibility.
The basic alarm will come with at least shock sensors, encrypted transmission, carjack protection, and some type of mobile app capability.
Mobile apps offer some of the coolest features, and the top security companies such as Viper use cloud technology to control and monitor your vehicle remotely. Keys aren't even needed.
Yet, you can check on your car or receive text and email alerts if someone attempts to break in. Some will also track the location of your vehicle using a GPS. However, they only reach about a mile at most.
Added features like these are much better than traditional car alarms that merely siren until someone who cares enough stops the sound, which has become a problem in large cities full of noise.
With added features, you don't have to track down your car to see what's going on or head outside to turn off the alarm in the middle of the night when a cat walks across the hood.
Do I Need a Professional to Install the Car Alarm?
While some car alarm systems require a professional to complete the installation correctly, which comes with added costs, others are easy to install yourself.
DIY installation models often are more affordable, but you need to know what you’re doing.
Some systems are complicated to install by yourself unless you have prior experience because it involves many wires and altering your car's electrical system as a whole, so a professional's help is highly recommended.
If you do decide to take the DIY installation route, be aware that doing so can also affect your car’s warranty or any warranties you may have on your vehicle’s equipment.
Are Car Alarms Covered with a Warranty?
Most car alarm systems come with a warranty, especially if you buy yours from an authorized dealer. If you don’t have a professional install the alarm, however, your warranty is moot.
Will the Car Alarm Drain My Battery?
Yes, alarms will drain your car’s battery. If it’s hooked up to the lights and horns, it may drain the battery faster.
Some systems may drain the battery entirely in just a few hours. The amount of power the drains will depend on the alarm you select and how many other car accessories run at the same time.
Can a Thief Disarm the Alarm?
Most alarm systems come with an emergency override that will allow you to disconnect it by merely removing a fuse or unplugging the car's battery.
However, once the car alarm is disconnected from a source of power, you can't start the vehicle. A thief may be able to remove the power source, but it would take much more time and effort than anything inside your car they could steal is worth.

Another affordable model similar to Pyle, the ScyTek A20 is a dual-zone alarm with a siren and lights that signal if anyone attempts to break in. The sensor offers a warning chirp if anyone gets too close to the vehicle, which sends thieves running.
It performs as well as many of the top named brands like Viper, but ScyTek is cheaper because it doesn’t come with convenience features. The remote isn’t two-way, so you must hear the alarm to know it went off.
