The Best Car Alarms For 2023

Your car is your road trip companion. It is considered as one of the valuable assets that help you make multiple memories.

Considering the importance of your car, it wouldn’t be wrong to say that every modern vehicle needs a premium and robust car alarm for the best security.

Not only does it protect your vehicle, but it keeps your important documents and stuff in the trunk safe. Nowadays, car alarms come equipped with advanced functions like remote unlocking.

Of course, a car alarm is too small to save your car from thieves. But, it does ensure the safety of your vehicle by allowing the vehicle owner to track their car.

Even if it is stolen, there is a good chance the thief will not be able to get away with it. This modern security device can help protect your vehicle anywhere.

Whether you have a brand-new car or a traditional model, make sure you install a high-quality car alarm to ensure your vehicle’s protection.

What Is A Car Alarm?

A car alarm is a modern security gadget that improves your car security. The latest models come equipped with a built-in car alarm. However, that might not be enough to catch a thief or a random person that steals stuff from your vehicle. So, it makes sense for the vehicle owner to upgrade the security level by installing an advanced and quality car alarm.

First things first, car alarms do not keep thieves from stealing stuff from your vehicle, neither can it protect your car from getting stolen. However, people will think twice before touching the stuff inside your car since the alarm will initiate the siren and the light. So, it only takes a few seconds for the alarm to activate and draw the attention of people. Another benefit of a car alarm is the built-in GPS system. This makes it easier for the vehicle owner to know the exact location of the vehicle.

You can manage and track your car on your mobile. Additionally, insurance premiums for cars with upgraded security systems are lower than those with no security features. Let’s discuss the 10 most popular and pocket-friendly car alarms for your vehicle.

Factors To Consider When Buying Car Alarms

There is no denying a car alarm system is one of the best security investments. With plenty of car alarm units available on the market, you will need to consider a few factors to choose the best model for your car. Obviously, security should be your main concern. But, there are a few other things you may want to consider when picking the best car alarm system for your vehicle. Let’s take a look:


Installation doesn’t have to be that challenging, but some wired units can take hours for accurate installation. If that’s the case, you will need to know the electrical system of your vehicle to connect the alarm’s wires properly.

It is best to get help from a mechanic or professional to install the unit on your car. If you are trying to follow the DIY installation steps, then make sure you read the instructions properly and attempt DIY installation only if you are familiar with your vehicle’s electrical system. We recommend you choose an easy-to-install DIY unit.

Shock Sensors

Another factor to consider when investing in the car alarm is its shock sensors. Remember that the quality of the shock sensors can vary from alarm to alarm. The quality of the unit determines the sensitivity and effectiveness of the alarm. You should choose a system that activates the alarm as soon as it detects someone trying to steal your stuff from the vehicle. Basically, the only possible way to get access to the car trunk is by breaking the glass window. If someone does that, the shock sensors initiate the alarm.

Likewise, you need an alarm that can produce a sound up to 100 decibels when activated. This will help you grab the attention of people around the parking lot.

Mobile Compatibility

As the technology is growing at a rapid pace, manufacturers are focusing on designing car alarms that could be integrated with your smartphones. An alarm that’s connected with your mobile makes it convenient for the vehicle owner to monitor their car from their mobile. You only need to install a mobile app to control your vehicle from any location.

The mobile-compatible alarm turns your smartphone into a car remote. In fact, some alarms come with added security features that notify the users through mail or a text message in the case of a security breach.

Now, the most interesting and useful security feature is the GPS-tracking option. Some units enable users to track the movement of their car if it is stolen. So, even if the car alarm fails to protect your vehicle from thieves, it will keep you updated with the current location of your vehicle. The only drawback is that the GPS-tracking functionality can cost you a few additional bucks. Make sure that you invest in a mobile-compatible car alarm for the best security.


The standard price of a car alarm is around $50 to $200. Customization, smartphone compatibility, and other smart features could add to the price. A quality alarm system is available for a hundred dollars.  However, you could opt for a $200 alarm that comes with added security and technical features (for example, encrypted transmission).

Two-way Remote

Car alarms are available in two types – one-way remote and two-way remote. If you want to upgrade the security of your car, then you need to invest in the latter. The one-way remote is only capable of locking and unlocking the vehicle’s doors. Such alarms can take signals only. We highly recommend a two-way remote for those who need a high-quality alarm that could take and give signals. These alarms will help you lock and unlock the door & turn on and turn off your alarm. Additionally, it also sends a signal to your remote.

Two-way remote features a display that enables vehicle owners to get an instant notification if the car’s AC and the engine is on. Some two-way remote units are customizable. You could invest in a model that can display advanced security notifications.


Some companies claim to offer a car alarm with a range up to a mile. But, distance should not be the factor to determine the range of a car, after all, you are not going to unlock the door from a distance as long as one mile. You should rather focus on the signal of the alarm. So, even if the alarm’s range doesn’t cover a good distance but offers a responsive signal, then that’s a good option for you.

Encrypted Transmission

The era when thieves would use a crowbar to break into your vehicle is long gone. In today’s digitally-advanced world, there are many tech-savvy thieves that use some advanced technical tricks to get access to the trunk of your car without breaking anything. It has become important for car owners to protect their vehicles and stuff from smart thieves who know multiple ways to break into the car without making it obvious. Encrypted Transmission is one such technology that offers security against digital tricks.

When you use a remote to send signals to the alarm, only the alarm unit can decode the message. No other device could decode this signal, except for the alarm unit. This makes it nearly impossible for a thief to use any hacking tool to read the signals sent between the alarm and the remote. So, no equipment or high-tech device can imitate these signals to switch on/off the alarm. The alarms can detect authentic and fake signals.

Different Types Of Car Alarms

Sure, a high-tech and premium car alarm can scare the thieves away. But, the overall security of your vehicle also depends on where you park your vehicle. There is no use of the siren when you park a car in an area with no traffic. Nobody is going to listen to the alarm sound. This encourages the thief to break into the system. Car alarms are available in different types. If you park your vehicle in a less-crowded area, then we would recommend the two-way remote as it offers the best security.


A silent alarm is a perfect option for car owners who need to park their vehicles around the noise restricted place. If the alarm detects a thief trying to break into your vehicle or drive it away, then you will be instantly notified either via your mobile or a fob. As the name implies, the alarm does not produce a noise, which means there is no way for a thief to know that the alarm is triggered. Hence, it makes it easier for you to catch them.

Remote Start

One quality of a remote start is that it enables vehicle owners to keep their vehicle warmed up in winters. Likewise, you can use the remote control to turn the AC on in summers to cool your car. The remote control allows you to manage your car from a distance. Whether you want to disarm the alarm or set off the AC, you could do it in one click. If you need to control your alarm with the remote, then you are going to need a two-way remote, which sends and receives signals.


A passive alarm activates as soon as you turn off the engine and lock the vehicle’s door. If you are looking for a hands-off car alarm that doesn’t need to be activated manually, then a passive car alarm could be a perfect fit.


Unlike passive alarms, active alarms operate on remote only. You can only activate and deactivate the alarm using the remote. So, even if you lock your car doors or turn the engine off, the alarm will not be activated unless you switch it on manually with the remote.

Bottom Line

So, these were the tips you must consider when investing in a car alarm. The above-mentioned alarms offer different security functions. It all comes down to your specific preference and the budget. We have mentioned affordable and high-end options. Consider the features listed above and choose the option that fits your requirements.


  1. Do I need to hire a mechanic to get the alarm installed on my car?

    As long as you are familiar with the electrical system of your car, you do not need to hire a professional to install a car alarm. You may also need to have the knowledge of using a wrench for a quick and smooth installation. Some units feature a detailed installation guide. This guides you throughout the installation. But, if you are not comfortable doing it on your own or you simply do not understand the electrical units of a car, then we recommend you get the alarm installed by a professional.

  2. Does the car alarm consume a significant amount of car battery?

    Car alarms do drain the battery. However, the answer to how much battery this small security unit drains can vary by the alarm. If the unit is extremely sophisticated and offers high-end security features, then it may drain a lot of battery. In fact, some users complain about the car battery being drained in a few hours due to the car alarm. Overall, you can expect an alarm to drain your car battery at an average rate of thirty percent a month.

  3. Can car alarms turn off automatically?

    Again, the answer varies by unit. Some models are designed in a way that they last for as long as 4 hours after being activated, while other models turn off automatically within 2-3 minutes. However, car alarms do not turn off automatically. You will have to switch them off manually (using the remote). The only time when the alarm disconnects automatically is when your car battery is dead and can no longer power the alarm.

  4. Is there some alternative to a car alarm?

    Yes, an immobilizer could be an ideal alternative. The only problem is that a car immobilizer is not a full-proof security option (just like the car alarm). Since thieves are using technology to break into the car by hacking the alarm signals, an immobilizer might not be a great fit for your vehicle. You should rather stick to the encrypted transmission to ensure 100% protection.

  5. When does the car alarm activate?

    When your car gets hit by something heavy or it experiences a significant force, then the alarm will be triggered. It will start to produce noise. Likewise, the alarm will be activated if someone tries to break into the vehicle. As soon as someone opens the door or breaks the window, the siren will activate. If the alarm is integrated with your smartphone, then you will get a notification as soon as the alarm activates.
