Car Alarms have become a necessity to keep your car protected 24/7. Whether you have a nice stereo installed, leave expensive equipment or electronics in the car, or are flat our worried that your car might be at risk of being stolen – you need a comprehensive car alarm to both protect your vehicle (and what's inside), as well as keep you informed in a moment's notice if something does happening to your car.
Today's car alarms have come a long way since the early motion detection and door lock alarms. They have sensors placed all around the car to monitor several things. From a door opening or window breaking to paint damage and tire jacking, great alarm systems will alert you in real time with detailed messages and displays that will show you exactly what is happening to your car. The higher quality alarms will incorporate satellite features will not only protect your car from damage and theft (and notify you in real time what's happening), they will also enable smartphone applications to connect directly with your car and give you the option to start your car before you walk out in the cold/hot weather.

Best Car Alarm List
Compustar CS6900-AS Quick Review
In addition to alarm, remote start and keyless entry functions, this all-in-one kit has a couple of tricks up its sleeve. Should the alarm be set off the transmitter sends a signal to the LCD remote to let you know. Likewise, if the shock sensor is activated, the system sends an alert to the remote. That way, should someone or something have hit your car while it was parked outside your house or apartment you have a chance to respond before the culprit disappears.
The kit comes with two remotes, one of which has a small LCD display screen. There's also a CM600 control module and a 105dB siren. Both remotes include trunk release although the second lacks any 2-way capabilities. Range is up to 3,000′. The system is suitable for diesel engines but not manual transmission vehicles.
Pros: alarm notification feature
Cons: needs a key bypass
Chrimestopper SP-502 Quick Review
If you're looking for a kit that includes everything needed for a complete security, keyless entry and remote start system, the SP-502 could be a very good choice. It comes with two remotes, one of which has 2-way functionality, and works on just about any vehicle, manual or automation, gasoline, diesel or hybrid.
The alarm system includes a shock sensor and 120 db siren that should be loud enough to deter any would-be thieves. There's also a starter kill that ensures your vehicle is fully immobilized.
The master remote, which as a range of 3,000′, displays confirmation of actions commanded on an LCD screen. As a bonus, it's rechargeable so you needn't worry about replacing batteries. The companion remote has a range of 2,000′ and lacks the 2-way function. Note though that this system has multi-vehicle capability, meaning the same remote can be used on a second car or truck equipped with the Crimestopper SP-502.
Other useful features are:
- Trunk release on the remote
- Data ports for interfacing with other devices
- Parking lights output (so you can spot your car in a dark parking lot.)
- Code hopping receiver (prevents anyone from “hacking” into your system.)
- Programmable for both tach and tachless as well as hybrid tachless connections. (The source of the engine start confirmation.)
- Incorporates a turbo timer that lets the vehicle run for a short period so the turbo can cool after you reach your destination.
Pros: Works on any type of vehicle.
Cons: Some reports that installation is difficult for the novice.

With the CS700-AS you get a lot for not much money, but of course there are some limitations. The kit provides remote start and keyless entry functions along with an alarm.

Common Terms & Features
There are many different types of car alarms, some with more standard features than the other. Knowing what type of feature is what will help you make an informed decision.
Keyless Entry – Keyless entry systems allow you to unlock your car doors by pushing a button on a remote. The remote connects with the alarm system to unlock/lock the car’s doors without the use of a key.
Remote Start – Remote start is a feature that enables you to start your car’s engine without actually being inside the car. You can use a remote or other device (depending on the unit) to remotely start your vehicle from hundreds of yards away.
Trunk Release – Trunk release is a form of keyless entry that is specific to remotely opening the trunk of your car. It enables you to open the trunk without unlocking the door from a remote. Sometimes you may want to just open up the trunk without necessarily opening up all of the doors, trunk release allows this.
Car Location – Car location is a form of panic button that gives you the ability to track down your car when you may not know exactly where it is. For example, you go to a concert, or a baseball game and don’t remember the exact row you parked in. The car location feature will turn the alarm noisemaker on so that you can follow the sound to find your car.
Two-Way Pager– Two-way pager alarms are those that not only send information from your remote to your car (like unlocking the door), they also receive information from your car. These types of alarms allow you to see in real time when an attempt to break in is happening, and alarm you from your remote when it happens. Some two-way pagers can work up to a mile away, giving you the confidence that your car is safe no matter where you might be.
Alarm Noisemaker – The alarm’s noisemaker is the most basic feature on a car alarm. It’s what makes noise when your car is being broken into in order to discourage the thief and draw attention to the car. Basically a loud speaker, the noisemaker is measured in decibels and the higher the decibels, the louder the sound.
Immobilizer – An immobilizer is a device that allows a vehicle from being started unless you have a key/remote that matches to the device. The key typically has a chip installed that communicates with the immobilizer in order to allow the car to start. This prevents thieves from being able start your car, even if they break into it.
Automatic Window Roll-Up – Automatic window rollup is a feature that will roll up the windows of the car after you have turned it off. Even though most of the time, you might be conscientious of your windows when you leave your car, the automatic window roll-up will automatically roll them up in the case that you forget.
Most of the aftermarket car alarms are compatible with any car, as long as it has a 12-volt system. However, there are some car alarms that don’t work with specific vehicles and it’s always best to check the alarm manufacturer’s website to check for compatibility.
