A car alarm is the best option to protect your car and other valuable possessions inside it.  Locked doors are not much of a deterrent, which is why keeping your car alarm activated is the only way to prevent thieves from stealing your equipment.

It is important that a good car alarm serves as both a deterrent and a response system. Many of these feature a 2-way pager system that gives you an alert when your car is being broken into, giving you a few critical moments to take action to prevent a burglary. 

The alarm should be loud enough that the audio of the burglary attempt will draw enough attention and radar to the car thief for the attempt to be aborted or foiled by law enforcement officials.

There are many car security alarms available in the market. Few of those car alarms are manual while others are automatic car alarms. We have done intensive research and found the top 10 best car alarms including the best automatic car alarms. We have done this research so that you may not have to waste your time looking for the best car alarms.

Viper 350 PLUS 3105V 1-Way Automatic Car Alarm Review

Viper has been making car alarm systems for many years, and it is one of the most well-known and trusted manufacturers. An alarm system with three channels and one-way communication is included in this version. You can use the remote control to secure your vehicle, but you won’t receive a notification if it’s being tampered with.

With this system, you are able to unlock your vehicle with the touch of a button and the use of two remote controls. There is a six-tone soft siren built into the alarm that can be synchronized with the vehicle’s horn for an extra level of sound.

In addition, there is a bright blue LED that warns potential thieves that your car is protected and provides alarm information, as well as a panic alarm that prevents carjacking.

The system automatically locks the doors once you start the engine and drive; when you stop, it unlocks them again. The system is sensitive enough to not be triggered too often but will be triggered when necessary. It is a good quality alarm system whose key fobs are very good, and the alarm system is also very reasonably priced.

Pros

  • Easy-to-use fobs included
  • Installation by a professional is not necessary

Cons

  • Remote range is shorter
  • There is no smartphone compatibility

Viper 3100V 1-Way Car Alarm System Review

An upgrade to the system that we mentioned previously from Viper, this car alarm system represents a significant improvement. There are two key fobs in this system that provide keyless entry to any vehicle and are designed to fit any vehicle.

It features a two-stage shock system for protecting doors, trunks, and hoods, as well as a system for immobilizing engines. Upon detection of tampering, it sounds like a siren with six tones. Additionally, a flashing parking light identifies if the system is unarmed or armed. Additionally, you can run diagnostics and view event reports.

There are also two universal power door lock actuators included in the kit. The relay module will need to be purchased separately if you do not have power locking. Viper’s 900 MHz Spread Spectrum Technology (STT) provides a reliable and affordable one-way automotive security system.  

Pros

  • A keyless entry system that prevents false alarms 
  • Starter interruption due to anti-theft technology 
  • Impact sensors with dual zones

Cons

  • One way car alarm

Viper 5906V Automatic Car Alarm Review

We’ve examined two alarm systems thus far, both from Viper, and now we’ll take a look at one that’s a significant upgrade. As an added convenience, you can start your car remotely using this system, again from up to a mile away.

Two fobs are included with this two-way system. One is a wireless HD color remote that alerts you when someone tampers with your vehicle, while another is a five-button one-way remote. The remotes can be used up to one mile away.

These key fobs are large. Even though these items are well-made and of high quality, some might find them too bulky and large for their tastes. There is also the issue that the buttons are quite sensitive, so you may need to take extra care not to accidentally press them.

Aside from that, it is a very effective system that is easy to install and does the job it was designed to do exceptionally well. The two-way Viper car security system could be worth considering if you look for a system from a trusted company.

Pros

  • The smart starter module can be separately purchased, though everything else is included
  • A great design
  • New technology and sensors for security
  • Remote control with an OLED display that can be customized

Cons

  • It is not cheap and might be out of reach for many people

Viper 3105V 1-Way Car Alarm Review

Viper again offers a simple but highly reliable one-way alarm system for entry-level vehicles, which includes keyless entry. Almost any car model can be equipped with this universal system.

A flashing parking light and clone-safe code-hopping technology are also part of this device. One of the benefits of comfort closing is that it automatically closes windows on some models of cars, but not all of them.

The system incorporates a six-tone siren, and you can also set your preferences for an interruption of your vehicle’s starter in the event your car has been tampered with.

You may want to consider this if you’re looking for a reasonably priced, basic car alarm and deterrent system rather than a two-way system. The system is easy to use and does exactly what it is intended to do.

X AUTOHAUX Car Alarm Review

The system is a simple, inexpensive, and highly effective keyless entry system and car alarm. Up to 984 feet away, it works and has a shock sensor to detect tampering attempts on your vehicle. It comes with central door locking.

In the event of interference, an alarm system of 80-120 dB is triggered. A carjacking prevention feature is also included.

The car parking warning alert is another useful addition to the system. If a door is opened while the car is stopped, the indicator lights flash for 15 seconds to warn other drivers when passing you to be careful.

Generally speaking, this option is a good one for an entry-level system that will protect your car when you’re not there. The installation should be handled by a professional.

AUDIOVOX Prestige APS25E Remote Car Alarm Review

An alternative budget-friendly car alarm system consists of two metal one-way transmitters with three-button controls and a siren with six levels of intensity. In addition to the shock detector, the transmitters function up to a distance of 500ft with a dual-stage sensor.

Lock and unlocking doors can be done remotely if you have power locking installed. To use this function, you must install an actuator if you don’t already have one.

This system has the advantage of being relatively easy to install. Despite the fact that the system can be installed without professional help, some people might still prefer to have it done by a professional.

Having a very sensitive sensor may result in false alarms, which can be a potential downside. In addition, the siren does not sound very loud – although this can be rectified by connecting the horn to the device. The overall result is that this is another excellent car security option

Pros

  • Notifies you when your alarm goes off
  • Sensors for impact
  • Reminders and monitoring of maintenance
  • Contains a GPS tracker as well

Cons

  • Compatible with some vehicles, but not all

It performs the functions of both an alarm and an access control system. It provides protection from unwanted intruders as well as remote locking, unlocking, and starting your car. The range of the system is up to 3,000ft, which is much further than most comparable systems.

In addition to the advanced shock detector, this system offers sensors for doors, hoods, and trunks to ensure that no one tries to break into your vehicle from any access point. Additionally, this kit includes a siren that can produce 105 decibels or more, ensuring that nearby people will be alerted if anyone attempts to enter your vehicle.

Two key fobs are included, one of which features interactive LED buttons – when you press those buttons you hear and see confirmation that the commands were sent, received, and executed.

There are many features built into this system that not only keep your car safe but also give you peace of mind, as well as give you the ability to control aspects of your security system remotely.

The system represents a great value for money for someone looking for something more sophisticated than just a one-way system – and it is also an excellent choice for someone looking for something that is more sophisticated than just a simple one-way system.

EASYGUARD EC002 Car Alarm System Review

A plethora of useful features is packed into this advanced alarm system. A universal system designed to fit most car models – however, it must be installed by a professional, so unless you have the right training you should not attempt it yourself.

There is also a push-button ignition, keyless entry, remote engine starting, and an intruder alarm. The touch password entry backup system uses the latest security features, such as code hopping and RFID technology.

Other useful features include valet mode, anti-carjacking function, panic mode, an audible alarm, and the ability to open the trunk remotely (though this may require additional equipment).

Using the system, the central locking can be controlled automatically, and the windows can also be closed automatically – this feature may also require additional equipment.

When you leave the vehicle, the system locks the doors for you, and when you return, the system automatically unlocks them. You don’t have to worry about forgetting to lock your car because this great feature keeps you from doing so.

All in all, an easy-to-use security system with plenty of practical features. Definitely recommended.

Pros

  • Entry by keyless system
  • Enables password entry (in case the smart key is lost)
  • User-friendly

Cons

  • Installation by a professional is required (hard to do)

A one-way system may seem like an obvious choice, but if you also want to maintain the highest level of safety, you ought to give this one a shot.

To determine whether somebody is attempting to tamper with your vehicle, it is equipped with sophisticated technology such as the Stinger DoubleGuard shock sensor. In addition, it comes with the Revenger six-tone siren that will scare off thieves and make sure everybody turns their attention to it.

Additional security is provided by the Failsafe Starter Kill, which disables the vehicle in the event of attempted theft, preventing the vehicle from being driven away. Having a bright red LED light on your vehicle will tell any potential thief that your car is secure. A flashing parking light is also included in the system.

There are two transmitters in the system, which allow you to disarm the alarm, arm the system, or lock and unlock the doors remotely.

There may be some limited features associated with this system as opposed to the many advanced high-end two-way systems available, however, for one-way alarms, it is a highly recommended product.

Pros

  • Protection from carjacking
  • Two-way LCD key fob remote
  • Start remotely
  • Easy expansion with four auxiliary ports

  • It does not integrate with smartphones

Viper 5706V 2-Way Automatic Car Alarm Review

Featuring four channels, two-way communication, an LCD display that is easy to see, and some of the slimmest key fobs on the market, this alarm system is exceptional.

Its controls are easy to use. Each package includes two key fobs: one with an LCD display, the other with five buttons. When someone tampers with your car, the fob will alert you, and when you return to your car, you will be given an event log, which will inform you about any shocks, etc.

You can also remotely start your car using the system, which includes triggers for doors and trunks. The system also lets you know the temperature inside of the car before you reach it, which isn’t something you find on many systems.

SmartStart compatibility makes it possible to connect the system to your smartphone and control its features through an app. It is also possible to control two cars using the same system. You will receive an alert via the remote if anything triggers the alarm. There is also the option to disable the actual alarm in the car and only receive alerts via the remote.

A system like this is ideal for someone who wants to make sure that their car is safe and who wants the maximum amount of control over the alarm system and other features.

Tips to Remember Before Buying a Car Alarm

Despite the fact that the majority of modern vehicles are equipped with some sort of alarm system, the basic measures aren’t strong enough to keep professional car thieves at bay. There are many features you can install on your vehicle to prevent theft and ensure its safety.

A car alarm system with aftermarket features will usually offer more convenience, as well. The following are some of the basic features to consider when purchasing a car alarm.

The alarm system and sensors: When your car alarm system is triggered, you should at least hear some noise. Make sure you choose a car alarm that includes shock sensors that will alert you if the glass is broken or if a substantial impact occurs.

You can use your remote control or smartphone to trigger these sensors. You should be on the lookout for sirens that edge above 100 decibels and do more than just honking and flashing lights to attract attention.

The range of Car Alarm: The range of some car alarm systems is phenomenal, reaching up to one mile. It is best to choose an alarm system that operates from as far away as 1,000 feet so that it can arm itself remotely. As a result, you’ll be confident that your alarm is set every time you leave.

Two-way remote controls and displays: Most modern car alarm systems feature two-way communication, meaning you can arm the system remotely while also receiving notifications on your remote. Many of these key fobs even feature LCD screens that detail the condition of your car, like the temperature inside or if it has been locked.

 

Integration with smartphones: You may be surprised to learn that some keyless cars have a smartphone-controlled car security system. Viper, one of the world’s leading security companies, takes remote monitoring and control to a whole new level with cloud technology.

You can use an app to track your car and receive email and text alerts without carrying around a remote control or key fob. In addition to providing GPS tracking, many of these apps allow the user to report thefts and find their phones.

Easy installation: There is a lot of wiring and tinkering in your car’s electrical system involved in installing a car alarm. Our recommendation is to hire a professional installer because installation can be complicated.

It will, however, raise the total price by several hundred dollars. DIY installation is not something you’re alone in trying. It has been a success for many handy car owners to install their alarm systems. It’s important to note, though, that DIY installations may affect warranties.

Featured conveniences: You can also remotely start your car with many car alarms, which can be useful on a cold morning to defrost your windows and heat your seats before your commute.

Some car alarm systems include extras such as keyless entry, trunk release, and valet mode, making life a little easier while you’re driving.
