Ideally, a good security system should deter theft, prevent theft and provide added convenience. Today’s systems offer audible alarms, and “two way” remotes that not only allow you to lock/unlock the doors, but will also alert you to a security breach – even tell you what the concern is (open door, open trunk, broken window, etc.). Many systems also offer remote start, which is great for warming up your car on cold days, or cooling it off in the summer months before you drive.
