Car Alarm Systems Frequently Asked Questions

Car theft can be silent and sneaky or brash and bold. It can happen at basically any time of day in practically any location. Here’s a look at how car alarm systems work and what features you’ll want to consider:

Does the Car Alarm System Noise Actually Stop Theft?

A blaring car alarm system is a pretty common sound no matter where you live. Most of us are relatively immune to the noise. A motion-activated honking is even standard on many different cars and trucks. Does a loud noise really stop car theft?

Yes and no. Car alarms can conceivably scare away a would-be burglar, but the noise doesn’t actually stop anyone from breaking into your car, and it also doesn’t help recover the car later.

What Features Should a Car Alarm System Have?

Fortunately, today’s car alarm systems are much more than noisemakers. The best systems combine a variety of preventative and recovery features. Here’s what you want to look for:

Car Tracking Capability

While a loud alarm system might scare away some would-be thieves, the most useful feature of a car alarm system is typically the tracking capability. Knowing exactly where the stolen car is located obviously makes recovery much easier for law enforcement. Car tracking often includes additional features such as geo-fencing and performance tracking.

Car tracking has been around for decades, with the LoJack system probably the most popular. However, the new twist for today’s world is the ability to monitor tracking from your smartphone. A tracking device can be plugged right into your car’s On-Board Diagnostics connector. You then download an app and you’ll be able to track your car’s position at any time.

Note that some of these tracking systems do require a monthly subscription fee. Typically, fees will range between $5 and $10 each month. However, because information is sent through a cellular network, you’ll be able to track your car practically anywhere on Earth.

Shock Sensors

Motion sensors will be found on almost all types of car alarms. If the car is jostled by a person or hit by another vehicle, a shock sensor alarm will sound. The alarm might be your car’s horn or a different noise made by the system itself. While alarms don’t necessarily engage members of the public, the extra attention can still be effective at chasing away thieves.

Advanced systems will have a wide range of sensitivity settings. They’ll also send a mobile alert so you can be informed of the situation even if you’re out of earshot of the car.

One-Way and Two-Way Remotes

Car alarms can have either one or two-way remotes. A one-way remote is limited to locking or unlocking the doors and arming or disarming the alarm. If your car alarm system goes off, you’ll need to physically hear it, because the key fob won’t flash, vibrate or offer any other indication.

The two-way remote gives you more information. You’ll receive real-time alerts either through the alarm key fob or your mobile device (or both). The alerts can provide specific information about what’s currently happening to your car or the key fob might simply vibrate, flash, etc.

Encrypted Transmission

As technology gets smarter, so do car thieves. In a weird way, certain types of car systems can actually make your car more vulnerable to theft. If the system uses unencrypted wireless technology, tech-savvy thieves can hack the signal and slide right into the driver’s seat. The best car alarm systems use encrypted wireless technology with all remote start and entry devices.

Carjack Protection

A variety of anti-theft features are designed to cause the thief to abandon the stolen vehicle ASAP. Carjack protection features include flashing lights, loud noises and a variety of other sight-and-sound assaults inside the car which basically force the driver to pull over. Not enough? Consider an ignition kill switch to really stop thieves in their tracks.

These systems are called “carjack protection” but they’re effective for any situation where a thief is behind the wheel of your vehicle (i.e., you don’t have to actually be carjacked).

Mobile Accessibility

Most car alarms are controlled by a fob which is typically kept on a keychain. This is often the easiest solution if multiple people drive the same car. However, smartphone-based alarm systems are growing increasingly popular.

Mobile apps allow you to receive text alerts and monitor your car in real-time. High-end manufacturers such as Viper are increasingly emphasizing secure cloud-based control instead of physical remote controls.

Remote Start Capability

Many car alarm systems include remote start. While this is convenient in cold weather, remote start is also a pretty important safety feature. When you can unlock the door and then start the car remotely, you can get into your vehicle quickly. Fumbling with keys while manually unlocking the door and then starting the car can place you in a vulnerable position. Remote start and keyless entry let you drive away from any location fast.

LCD Display

LCD didn’t used to be a standard feature, but now that car alarms have advanced, it’s much easier to find them. They can offer functionality and help with operations during low light or rainy conditions when you may not be able to check otherwise.

LCD remotes provide a lot of information about the operations of your car. When you combine it with a two way remote, you’re able not only to see the alarm but see extra information from the keyfob itself. It’s a really good feature, and now that more alarms are becoming more advanced, you’ll see this feature more often.

It’s also an excellent way to help differentiate between more capable alarms and those that just offer basic services. As alarms become more affordable, you may want to add extra features that help ensure that your car remains safe and cared for.

Can I Install a Car Alarm Myself?

Generally, you only want to install a car alarm system yourself if you’re more than moderately comfortable working on your car, especially with the electrical systems. Most people are usually better off with professional installation. Not only will you know the alarm is installed properly, but professional installation is often required in order to maintain the manufacturer’s warranty.

Installing car alarms yourself can actually be pretty dangerous. The typical installation requires splicing wires in the electrical system, which can cause a fire and other major damage if done incorrectly. Additionally, installation instructions typically aren’t written for a layperson.

How Can I Prevent My Car from Being Stolen?

Most car thefts are victims of opportunity. If your car seems difficult to break into, most thieves will simply move on. Make your car alarm known. A car alarm sticker in the window and a blinking light on the alarm system are two simple but effective ways to deter theft.

Unfortunately, an alarm system isn’t enough to prevent every theft. Here’s a quick rundown of some simple but effective tips to help prevent your car from being stolen:

Lock Up!

Don’t forget the basics. Always lock your car doors and make sure all the windows are rolled up. Also avoid storing a second set of car keys anywhere inside the car, such as under the visor.

Additionally, never leave the car running unattended. This practice is especially popular during periods of cold weather. Called puffingdrivers will start their car and leave it to warm up – only to return in a few minutes to find their car has been stolen, often from their own driveway!

Use a Dash Cam

Dash cams are growing in popularity across the country. These video cameras typically cover the front of the car. While they’re mainly used to identify fault in accidents, they’re also useful in parked cars. A dash cam can help capture video footage of any potential car thieves.

Park in Safe Areas

When parking in public, always choose well-lit areas near other people when possible. Avoid parking far away from stores in darker locations. Even professional car thieves need at least a few minutes of solitude to steal a car. Consistent foot traffic can help keep your car more secure.

Lock the Hood

Thieves might be more interested in specific parts of your car than the whole thing. A car alarm doesn’t do a great job preventing someone from popping open the hood and stealing engine components. Hood locks are a simple solution to keep valuable engine parts safe.

Do I Need An LCD For My Car Alarm System?

No, you don’t need an LCD option with your car alarm, but it makes operation a lot more straightforward. Many of them have keyless remotes that can do everything from killing the ignition to telling you the temperature inside the car.

The LCD remote can help you with basic operations even when the lighting conditions are bad. Many newer car alarm systems offer this kind of functionality as a standard feature instead of something extra. You don’t need it, but it can certainly provide an extra boost to your usage.

Final Thoughts

Your car doesn’t need to be defenseless when you’re not around. A car alarm system helps protect your car day and night no matter where it’s parked. While loud sirens and alarms can help deter theft, tracking systems help with recovery efforts if the car is stolen. Additional features such as smartphone-based monitoring, carjacking protection and more also help keep both driver and vehicle safe.

Don’t be a victim of car theft. The best car alarm system helps keep your car in the hands of its rightful owner – you!
