Find The Best Car Alarm to Protect Your Asset

Why do you need the best car alarm? Here’s why:

According to the National Crime Insurance Bureau, a total of 721,885 motor vehicles were stolen in the USA in 2019. Additionally, the state of California had the most number of vehicles stolen—141,757.

Even if you live in Vermont, the state with the least recorded car theft in 2019, protecting your car is still necessary. However, you should also find a car alarm that provides the perfect security solution for your needs.

Aren’t car alarms obsolete?

Car alarms may have somewhat fallen out of vogue. But there are two main reasons why.

Firstly, they go off too easily, especially if you live in a big city. So, when an anti-theft alarm for cars blares, it’s most likely a false alarm. As a result, this only adds to noise pollution and desensitizes both car owners and bystanders.

Secondly, experienced thieves know how to disarm an alarm within 10 seconds of it going off.

Despite this, car alarms are still extremely useful. Experienced car thieves may still be dissuaded if they see a bright alarm LED on the windshield and the manufacturer’s sticker on the windows.

Car alarms cost as low as a little over $20. If you want to increase your car’s security, you can also add other best car anti-theft devices like a wheel immobilizer, a window identification system, and a Failsafe Starter Kill system.

10 Best Car Alarms

Viper 3105V Entry-Level One-Way Security System

  • Good price-to-quality ratio

  • Two four-button remotes

  • One-way communication

That means that you won’t get feedback from your car to tell you that your commands are actually being executed. More importantly, the system has no way of notifying you that the alarm has been triggered, so you have to be in hearing range to know what is happening. This explains the low price.

What to Look for in Vehicle Alarms

Remote-Start Systems

Nowadays, alarms are usually sold in bundles with remote-start systems. It’s the best car alarm system since it allows you to warm up the engine and chill the booth before entering the vehicle. Almost all of them are smartphone compatible. Using the auxiliary channels on these systems, you can connect them to any electrical feature you have installed in your car, such as the trunk popper, electric windows, or the sunroof.

There are two main types of remote-starter and automobile alarm systems: one-way and two-way communication systems.

In two-way communication systems, the remote is capable of receiving feedback from the modules in the vehicle. Indeed, a two-way system is a car alarm that notifies you when your vehicle is being tampered with and lets you know whether it has executed your commands, including starting the engine or rolling down the windows.

In a one-way system, the module in the car doesn’t communicate with the user.

This feature also makes the biggest difference in price. Two-way systems are two to three times more expensive on average.

Shock Sensors

Secondly, a discriminatory shock sensor car alarm is something you should consider. A car alarm that goes off too easily is just as dangerous as a car alarm that doesn’t set off at all. If the alarm sounds three times a day, how will you know whether you have a real emergency or just a false positive?

The best systems feature the Stinger DoubleGuard shock sensor. This technology can identify an accidental bump or a car speeding too close and distinguish it from a real burglary attempt.

List of Best Car Alarm Features

The range of the alarm: Some systems detect and transmit radio frequencies from up to three miles away in optimum weather conditions.

LCD screen: Most two-way communication remotes have LCD displays with icons depicting what state the car is in. This shows whether the alarm is armed, the windows are closed, and the door is locked. One-way communication remotes usually don’t have displays.

Battery life: For top car alarms, you shouldn’t have to worry about the batteries more than once every six months. In many cases, charging the battery takes just a couple of hours.

The number of auxiliary ports that come with the system (usually between two and four): These ports can be connected to any electrical system in your car, including the trunk, the sunroof, and the lights.

The type of siren: The most popular sirens on the market are the Revenger and Neo Revenger sirens. Those are the old-fashioned six-tone sirens we’ve all grown accustomed to. The best alarm system for your car should have a siren that belts out around 120 dB of ear-piercing noise.

The number of buttons on the remote: The more buttons a remote has, the more customizable it is and the more options you have. The best remotes have up to five buttons.

Failsafe Starter Kill: This anti-theft device disables the ignition so no one but you can start your car, even if they have a key or try to hot-wire it. It comes bundled with some of the best car alarms and is highly recommended for expensive vehicles.

Remote start: This allows you to start your car from up to three miles away on some models.

Guaranteed protection plan (GPP): This is an insurance policy offered by some manufacturers, including Viper. It guarantees a $2,500 insurance deduction if your car gets stolen within a year of installing an auto alarm.

Panic mode/car locator: This feature allows you to manually activate your car alarm. It can help you find your car if you forget where you park it, or cause confusion and draw attention in a stressful situation, making it an important feature on the best car alarm on the market.

Silent-mode switch: This turns the activation chirps on or off.

Frequency-shift keying (FSK), sometimes called code-hopping: This ensures that the remote switches radio frequencies to avoid third-party interference with the signal.


There are many debates over the effectiveness of car alarms, and both sides are right. If the thieves want to get your car, they will find a way. But the main point of a car alarm is to deter thieves. They are not doing this for enjoyment, no matter what Hollywood claims.

They are not in it for thrills and just want to steal a car as quickly as possible, and anything that will make the process more difficult will make them choose another vehicle. So, if you’re wondering if a car alarm is a wise investment, our answer is yes.
