Alarm features

Alarm systems offer a variety of options that go far above and beyond simple the keyless entry from the factory. Note that not all alarm systems offer all of these features. Write down the ones most important to you when shopping for an alarm system.

  • Two-way remotes give you feedback on your car's condition and response to commands.

  • Starter kill prevents your car from being hot-wired.

  • Motion sensors let you leave the top down or the windows open. They are also good for protecting the cargo areas in vans and trucks. The sensors will sound the alarm if someone invades your space.

  • Glass-break sensors sound the alarm when they "hear" a window breaking. This protects you from the thief who believes he can bypass your alarm by not opening the door.

  • A tilt sensor monitors the tilting of your parked vehicle caused by an attempt to jack up or tow your vehicle.

  • Driver's side priority unlock lets you open your door without unlocking the others. You can get in your vehicle without letting your guard down.

  • Auxiliary outputs allow you to expand the alarm's capabilities by adding features like a remote starter or window controls. Most alarms come with at least one auxiliary output. Consider everything you want the security system to do (now and in the future) when choosing an alarm.

  • Remote starting is the epitome of convenience. Remote start features either come built into a security system or can be added later with a remote start module.

  • Smartphone compatibility — some remote systems let you use your smartphone for control, giving you unlimited range when you have phone service. Often, a separate smartphone interface module will have to be added to a remote start system in order to get the smartphone features.

  • Consider adding GPS tracking capability to your security system so you can find your car in a crowded lot or if you forgot where you parked it in an unfamiliar place. Want to keep an eye on your teenaged driver? With a GPS tracker you can keep track of your vehicle's location, and receive alerts when it leaves or enters a pre-programmed area, or is traveling too fast.

A good security system not only makes your car more difficult to steal, it also makes it easier to live with. The small remote control usually replaces your factory key fob and lets you arm and disarm the alarm, lock and unlock your doors, and maybe even zap open your trunk. Some systems let you use your smartphone to control and monitor your car's security. How's that for convenience?

No one enjoys waiting for a car’s HVAC system to catch up to the conditions during extreme temperatures. A remote start system is a great way to get every drive off to a comfortable start. Whether it’s freezing cold or broiling hot, a remote start system will ensure that your car or truck is ready to roll when you get behind the wheel.
