The best option for preventing car theft lies in adequate protection. By installing a car alarm, the chances of stealing become lower, and your vehicle security raises to the next level. Plus, you can lower car insurance premium, since a lot of insurance agencies offer discount for vehicles with anti-theft feature.

In this article, you’re going to see the crucial features of the best car protection products, their installation and 5 best car security system models which are suitable for every vehicle type.

Best Car Alarm System Characteristics

Car alarms have been used for ages, and they are not considered as a modern invention. But, as technology develops, they become equipped with stronger security systems which are able to prevent even the trickiest theft attempts.

Have a look at ten essential features of the best car alarm system:

Keyless entry system: this feature allows you to unlock your car by pressing the button on the remote. Most keyless systems use the rolling code, which generates a new random sequence every time after the vehicle's been unlocked. It's useful in preventing relay attacks.

Remote startup: it’s similar to the keyless system – it helps you start your engine even if you’re not inside of it. Most modern car alarms allow you to start your car from a long distance.

Immobilizer: it’s a system that prevents your car from being started until the key matches with the device – it’s especially convenient for stopping the thieves from “hot-wiring” the car even though they manage to break the glass and get inside.

Car finder: this feature is practical when you leave your car in crowded parking. By pressing the panic button on your remote, the alarm will produce a noise that will help you find your vehicle fast.

Two-way remote: classic car alarms come with one-way remote which only provides locking and unlocking the door and arming and disarming the alarm remotely. However, the newer ones include two-way pager which sends you the alerts if someone tries to break into your car.

Carjack protection: this is an optional feature which you can add to your car alarm system – it combines lights and high-pitched siren which make the thieves leave the vehicle immediately.

Encrypted transmission: as the attacks become more sophisticated, the car needs more tech protection. This feature adds encryption to your wireless car alarm system, and it prevents the thieves from hacking the signal from your key and unlocking your car without physical contact.

Shock detectors: in case your car gets hit or pushed, this motion sensor will trigger the alarm and send you a notification via the mobile app.

Ignition feature: this platform will lock all doors on your vehicle as soon as you jump into it. That prevents any unpleasant guest from trying to get into your car, no matter if you're parked or in motion.

Smartphone compatibility: the majority of modern car alarm systems are smartphone optimized – they have developed a cloud technology so that you can monitor the car right from your hand. Using mobile apps, you can check the e-mail and receive text alerts, and, the best of all is that you don’t need to carry extra remote or key fob.

Installation is also something that you should have in mind. Many of the car alarms are easy to install, and they come with the step-by-step installation guide. On the other hand, some require additional tech support and if you're not sure how to do it, better call an expert.

When purchasing a car security system, make sure you look for the one with some of the mentioned characteristics – a simple blaring siren is not that powerful like it used to be and it’s not going to protect you from the sophisticated car thefts developed by tech-savvy criminals. Think wisely and react on time.

The Best Buy Car Alarm System in 2020

When it comes to the car alarms, the market has a lot to offer – from the basic devices suitable for older car models to high-tech machines which provide your luxury vehicle with an additional step of safety.

  • Compatible with Smart Start: Smart Start is a mobile app (both for Android and iOS) which allows you to start, locate and control your car virtually no matter where you are. You can also set safety notification in case your car is speeding or goes in the wrong direction.
  • Computer Programmable: this feature provides simple configuration, and it allows you to set advanced controls of this car alarm system via PC, tablet or any other electronic device.
  • cons

    It’s firm, reliable and it can fully replace the standard door lock.


  • Virtual Tach: this feature doesn’t require the tach wire in most installations. A tachometer signal informs our remote system when to stop cranking the engine, making sure you don’t overdo it.

  • Installation: Unlike standard car alarm systems which often require tech-savvy assistance, RV 4.0 is easily set up. The instructions are clear, and it takes about 10 minutes to install it.

    Bottom line: This car security system is especially convenient for large vehicles like trailer trucks and campers, and it provides a practical way to enhance your car security. However, its price is a significant limitation.

    3. Viper 5706v LCD 2-Way Security + Remote Start System ($205.00)

    Have a look at the Viper 5706v – it brings the newest security features to your machine and its remote control modern design will fit the car style perfectly.


  • Trunk release feature: like many modern car alarm systems, this one also includes a trunk release feature – press the AUX button and open the trunk remotely. The sound will notify you that the trunk is unlocked, and you’ll also see the picture on your screen. The same is when you lock it.
  • Full silent arm protection: this feature sends you messages on the remote while the siren and parking lights are disabled. This feature is useful if you don't want to raise panic and it's easier to catch the thief since he's unprepared.

  • Encrypted transmission: all Viper car alarms come with security systems that encrypt the data sent from the remote to the wireless system. There is also a Clone-safe and Anti-code grabbing technology which doesn't allow the hacker to get into your car alarm system signal.
  • cons

  • Not so manual transmission friendly: most Viper products are primarily made for the automatic transmission. In case you own a manual transmission car, you'll need to do some extra settings.
  • Installation: this product's system is quite complex, so you'll need to contact a technician to install the alarm correctly.

    Bottom line: This product is especially convenient for more expensive cars since they are usually a target for criminals. It's costly, but it provides a lot of features that you won't find on any other car security system.

  • cons

  • 1-way paging: even though it offers a variety of essential features, it lacks a 2-way remote option. So, you’ll need to have a look through the window and see if the command has been executed.

  • Heavy braking or acceleration alert: in case someone is making harsh movements inside your vehicle, you'll be automatically notified via the mobile app. This is also associated with teen drivers since they’re mostly in training and they tend to make those movements due to their inexperience.
  • Carlock smartphone and web app: this is one of the car alarm systems which is cloud-optimized. It allows you to have insight into the exact number of miles you drove, the exact location and even the driving record. That could be useful when it comes to car insurance since it has an impact on the policy price.
  • cons

  • Subscription to the Carlock: when you purchase the device, you get 30-days free services; however, as soon as it expires, you need to renew the license and pay $113 for the annual fee, or $9.60 per month.

    Bottom line: This is the most affordable car alarm system of this list, and it provides a lot of features which enhance your vehicle security. However, the bad thing is the subscription, which is annoying to most customers, but at least you have an opportunity to try the services for free and see if they meet your needs.

    Important Note

    The price is an essential factor when it comes to purchasing devices, but don't get hooked by the cheapest options. Make sure you buy from the authorized dealers and get adequately informed before you make a payment.

    When you buy from untrusted sellers, your warranty won't be valuable, and in case something happens, you have two options – to throw the device in the trash or to pay for the repair out of your pocket – and both options are painful.

    Besides, be careful when it comes to the installation. If you’re not sure how to do it properly, avoid experimenting and hire a technician who’ll make sure that everything is all right. Otherwise, you risk losing your safety, your nerves and money.
