One of the most popular ways that thieves do to break into your vehicle is the smash and grab. If you are the type that usually leaves important and expensive items in your car in plain sight, you are one of those that are inviting car thieves to smash the window of your car and stole your belongings. While there is a noticeable theft restriction and even there is an alarm activation, smashing the window, getting the items, and running away only takes several seconds. Most of the time, the thief, as well as your belongings, are already gone before anyone even notices your alarm goes off.
