Hint... don't store leaky acetylene tank in your trunk

A keyless remote was the key to how a 2012 Honda Civic suddenly exploded in the parking lot of a Stoneham, Mass., shopping center Sunday afternoon.

The vehicle's owner, Jackie Sagrue, and her boyfriend were walking toward the car when she pressed her remote.

“I unlocked my car and then immediately after that I popped my trunk and then my car just exploded all over the parking lot,” Sugrue told MyFox8.com.
