Car alarm installation cost guide 2023 (updated) (2023)

Since the first recorded case of auto theft in 1896, cars have always been a popular target for thieves. They have a high value, can be divided into individual parts, and can also make it easier for a thief to escape.

According to researchers, car theft is less common today than before. One of the main reasons for this is that due to advances or increased sophistication in car alarm technology, it is becoming increasingly difficult for criminals to break into a car.

Many people point to this statistic and claim that it proves that car alarms are no longer important, when in fact it proves the opposite: that we should continue to use these systems to further reduce crime.

How much does it cost to install a car alarm system?

Car alarm system costs vary depending on the complexity of the desired system and the type of vehicle used. Since there are many different providers and sellers in this niche, the prices can become competitive depending on your perspective.

Retailers like Best Buy, Walmart, Target, and Sears sell car alarms, but these retailers typically don't include installation with the purchase.

You can buy an alarm system for as low as $12.99 from online stores that includes two remote controls, a siren, and a wiring harness. But to have the system professionally installed, you need to find a local retailer who can do the job.

Installing a car alarm yourself is an option, but keep in mind that doing so may void the warranty on the product you have purchased. There is a DIY guide at the end of this article.

How does a car alarm system work?

A car alarm actually serves a very simple purpose: to prevent unauthorized access to your vehicle and to deter would-be thieves. The components that make up a car alarm generally consist of a computer, receiver, speaker, and sensors.

Depending on the year and model, a car can have between one and ten different sensors. Basically, the sensors monitor illegal activity and send the data to the alarm computer, which then activates the siren (speaker).

Some systems are also sophisticated enough to turn off the alarm when certain conditions are met.

A key fob with a built-in radio receiver is available for some cars, allowing the user to wirelessly control the alarm system to arm or disarm it.

That's it, but there are more details that make up some unique detection methods. There are different types of car alarm sensors used in modern vehicles:

  • door sensors
  • shock/impact sensors
  • microphone sensors
  • tilt sensors
  • proximity sensors

Door sensors are the most common sensors and are simply activated when a burglar opens a door while it is locked with a pick or pick. The shock and impact sensors are activated when the thief decides to break a window to gain entry. These sensors can sometimes be activated accidentally.

However, some car thieves are quite clever and use special tools to avoid breaking a window and setting off the crash alarm.

To counteract this, some car manufacturers have installed microphoned alarms that monitor sudden and loud noises in and around the car. Due to the way these sensors work, they can occasionally give false alarms.

Tilt sensors prevent thieves from taking the car completely. By monitoring the angle of the car, the computer can detect if the vehicle is leaning and sound the alarm if it is active.

These sensors use mercury-filled devices that flow to one side or the other in such a case and send electrical signals to the computer and emit sounds from the speaker.

Another type of sensor, the proximity sensor, scans an area around the car for movement. These sensors are designed to only detect movement very close to the vehicle and at a certain speed.

They are usually installed in high-end vehicles and also tend to accidentally activate from time to time.

Modern car alarms use a backup battery so they keep working even if the main car battery is dead. This is useful as car thieves often first disconnect power to the vehicle by cutting the battery cables under the hood.

A sudden loss of battery power like this would activate the backup battery power and send a signal to the computer that would trigger the alarm.

Common problems with car alarms

Car alarms can have a few issues that you need to be aware of. Often the problem is due to age or poor internal wiring.

(Video) Best Car Alarm In 2023 - Top 10 Car Alarms Review

Find out the status of your alarm system to ensure it's always in top condition and ready to deter burglars.

A car's remote entry system can fail if the remote's battery loses power. If you're having trouble turning the alarm on/off with your remote, replace the battery and see if that resolves the issue.

Another annoying problem is when the car alarm goes off by itself randomly; often in the middle of the night. The alarm system is faulty; you need to disable it in the meantime before you can repair the car. Please bring it in asap as your car is vulnerable to thieves during this time.

If you bought a used car, the wiring system for the alarm may have been installed DIY-style and done incorrectly. If you suspect this is the case, have the car checked out by an ASE Certified Auto Technician immediately.

Is there anything else you need to know?

When purchasing a car alarm, make sure that the supplier posts all relevant policies such as labor costs, warranties, warranties, etc. to help you make a better decision. Check if they specialize in certain types of vehicles or if all models are covered.

It is recommended to check the rating with the Better Business Bureau for any complaint. Opinions from other customers can be extremely helpful.

If you only want to invest in basic protection, a car door sensor should do the trick. However, if you need more advanced protection in an area with a lot of crime, opt for an alarm system with more detection methods.
