For this reason, it is very important that you know how to compare car alarms, so that you can choose the model that best suits your needs. Given so many models that the market offers, we have made the decision to help you in your choice with the following guide to buying the best car alarm, where we mention the most relevant aspects that you have to consider when making your choice.

Shopping guide

alarm types

There are users who are looking for the best in technology, which is why manufacturers have included innovative functions that allow you to open the doors of your vehicle and even start the car from the same remote control. This clearly comes at an extra cost, but if you’re not too concerned about how much the device you’re buying is worth, feel free to pick a model that has remote start capabilities. 

Given so many different models and types of car alarms, it is best to know the different types of systems that you can get. It is important to take into account that there are basically two large groups: the basic models and the advanced models. The basic models have the function of alerting people who are near the vehicle, when it is under attack. Its operation is based on the emission of an acoustic signal loud enough for nearby people to know that they are trying to break into the car.

On the other hand, you can choose an advanced car alarm model, which stands out for being a much more complex and complete system than the manual one, since, in addition to the acoustic function, it allows the location of the vehicle via GPS, disconnecting the battery from the vehicle automatically or, even, some models incorporate a practical microphone that allows you to hear what is happening around you.  

There are also innovative smart car alarm systems or two-way monitoring that include a connection module to send you a notification to your smart device in the event that the doors to your vehicle have been opened, a window has been broken or if it suffers any movement. In this case, we recommend choosing a model that allows direct connectivity with your mobile phone. Also, if for any reason you are out of your city and need to arm or disarm your vehicle, you will be able to do so with ease.

price always matters

In any comparison of car alarms, first of all, it is very important, before making your choice, to take into account if you want to acquire this device for your personal peace of mind or if you need an alarm for your vehicle due to the large number of robberies that happen where you live. The idea is that you do not spend more than necessary, especially if you have a small budget and are looking for a good and cheap car alarm. 

These items are especially important if you are living in a busy city and where theft of motorcycles and vehicles can become very common. If you do not have as much risk of having your car stolen, we recommend choosing a cheaper model. 

Use of controls

Any choice of car alarm must include a remote control with which you can deactivate your alarm from wherever you are. It is important that you know that, traditionally, car alarm controls work bidirectionally, operating with radio frequencies, which naturally can present inconsistencies in wide areas of long distances or with great use of electronic frequency such as apartments. or buildings. 

We recommend you look at the range and speed of operation of the signal between the command and the alarm offered by the product on the network. Please note that it is very likely that if the total distance is more than 400 meters between you and your vehicle, it is very possible that stable and efficient communication with the alarm cannot be maintained. You should always verify that the device works perfectly from where you need it.

Installation type

It is very important to look at the exact place where the device can be installed, since, while there are magnetic models that easily adapt to almost any metal surface, there are simpler models that can be stuck with any double-sided tape. 

On the other hand, it is also always suggested to install car alarm systems in hidden places so that they cannot be easily dismantled, therefore, try to make the device you purchase compact.

Frequently asked questions

Q1: How to disable my car alarm?

First, try putting in the key and trying to lock and unlock the driver’s side. The second thing you can try is to lock and unlock the door, but using the key fob, making sure you are within signal range and that the remote has batteries. Stand close enough to the vehicle and try again.

Also, you can make sure you haven’t accidentally pressed the panic button, as some key fobs include this button to help unsuspecting users find their vehicle, so pressing it triggers the alarm non-stop. Finally, try to start the car with your keys, even if the alarm continues to sound, since some manufacturers put systems that stop the action of the alarm as soon as the owner of the vehicle inserts his key.

Q2: Why doesn’t my car alarm sound?

On some occasions we may come across the fact that our alarm system does not emit any type of sound when activated. If this occurs, basically the following could be happening. It is very possible that the alarm has been programmed with a silent arming and disarming function, which some models incorporate as a security method and on these occasions the alarm will not sound. To fix this, check the manufacturer’s manual so you can adjust it again, where you will be prompted with a series of keystrokes to return the device to active sound.

Q3: How to know if a car has an alarm?

There are several really simple ways to find out that your car has an alarm or, at least, that it works correctly. One of them is making sure that the red or blue light that alarm systems normally have are flashing in a common way. If you can’t see any lights in your car, you can try locking yourself inside the vehicle and then try opening the door from the inside to see if the alarm goes off.  

Q4: How to install a car alarm?

All battery models usually have at least two cables to make this type of connection, in addition to the fact that they usually come in a standard color to avoid any type of problem or confusion in the connection. Keep in mind that the color red is always used for the positive and the color black for the negative cable. The red cable, which is always connected to the positive of the battery, always has a protection fuse. Some manufacturers integrate a third yellow cable, which is responsible for the ignition of the vehicle. This connects to the ignition switch output.

Q5: How does the car alarm that warns you on your mobile work?

Car alarms that have a mobile phone notification function are because they usually have geopositioning systems or connectivity modules similar to WiFi, with which, in case your vehicle suffers any threat, they either try to open it move it, you can automatically receive a notification in the corresponding application of your smart devices.

Also make sure that all the contents of the package are present and that you are not missing any component.

Proceed to install the system

The first thing we must do before making the cable connections is to design a wiring diagram, since each car has a slightly different current distribution, so there may be some slight variations and how these systems are directly connected to certain important parts of your vehicle, it is better to have that aspect in view.

Remove the panel cover

In this process, you will need to open the hood and you will notice that at the bottom there will be a siren system installed, as some vehicles have their own siren system. That part of the vehicle is where you are going to connect the new car alarm system. It should be noted that this installation is done in a private place such as a workshop or garage and not on public roads.

Direct connection to the battery

Car alarms must be directly connected to the battery, so that they can have the necessary energy they will require to be activated and in case the vehicle suffers an attack or in the event of any type of emergency. In addition, the fuses must be connected to the central power cable, so that it can have the necessary power to fulfill its functions.

test the system

Finally, you must press the alarm’s power button to verify that the connection has been correct and that it emits a sound. If you have followed the manufacturer’s instructions and our suggestions carefully, you will hear an audible indication and you will see how the door locks are armed or disarmed. In case your system controls the ignition of the vehicle, you will be able to start the car from your remote control.
