Did your car come with a keychain pager, a small device that lets you lock or unlock your car doors from afar? They're a basic accessory for new cars and provide convenient ways to make sure your doors are always locked. The Commando FM-870 is a souped-up keychain pager. It can unlock car doors without a key and start the engine remotely from 2,500 feet (762 meters) away. The Commando includes a small device with an LCD display that monitors doors and trunks open/closed and can detect hard impacts to your vehicle [source: Commando].
Forced entry or engine startup will trigger an alert to the Command FM-870's LCD display. In addition to its remote start and keyless entry functions, the Commando component that's installed in the vehicle also includes a car alarm that can be programmed to trigger based on unauthorized vehicle access. The multi-function Commando FM-870 sells for $169.99 on Commando's Web site. The installation process for the Commando requires some manual wiring so make sure you or someone you know is capable of installing it before making a purchase.
While the Commando FM-870's LCD-equipped remote helps it stand out from the crowd, it's far from the only multi-function security system on the market. Next, let's take a look at the Viper 1002.
