That's all it takes---start to finish---for a crook to open your seemingly secure garage door.
But in a NewsChannel Four investigation, Linda Cavanaugh shows you how to stop thieves for only pennies.
When Linda showed homeowners a video of how burglars break in, they were astonished.
"Oh, my God. He did it with a clothes hangar?"
"That's crazy stuff isn't it? That is crazy."
The technique is called fishing.
John Wester of Ace Garage Door showed us how it's done.
Watch our video to see the technique. (We've left out a step to avoid teaching thieves how to do it.)
It takes John Wester only four seconds.
"The garage door is one of the weakest points of any house," Wester says.
It's easier if burglars can see through your garage door windows.
But even windowless garage doors are vulnerable.
"It's not as easy but it's extremely doable. It may take a little more practice but like any professional, they're going to practice at their trade."
The solution is a simple zip tie.
It costs just pennies.
You'll see in the video that the zip tie is threaded through holes on your garage door opening device. It prevents thieves from being able to pull on the emergency latch to open your door.
It's a small expense to make sure your garage door is secure.
"This is definitely a quick easy fix," Wester says.
