Active shooter scenarios have increasingly become a part of daily life, and students at CCTI created locks they built to re-enforce doors. News 13s Dominic Barone shows us how these students are trying to make schools safer.

When a shooter enters a school or business, protocol says to lock the door. Four CCTI students invented two different door locks to make sure no one gets in.

"We kind of just thought about making a different one that maybe could be a little bit easier and that's on stationary and takes three to four seconds just to flip on." Cameron Ahner said.

Ahner thought of the idea and recruited three others to help him design and produce these door locks. You can call them the Lockefellers. Their first lock is universal to any hydraulic door, and all you have to do is flip it up.

The other one is made for double doors and can be in place within in seconds. Evan Brazil says the whole idea was to make locks that could be set under extreme circumstances.

"It's very easy for anyone who's under stress or anything. You just have to flip it up and it stays there and that's it. There's no locks. You don't have to find your right key, you don't have to turn the lock or anything like that you just have to flip it up and then it's done." Brazil said.

Austin Schweibinz says there was a lot of trial and error in the machine shop before getting it right.

"We had to mill the middle of the body out and then to get a better finish and straight edges on the other lock we also milled those out." said Schweibinz.

The first three boys are precision machinists, but Alex Crostley is the welder who brings the double door lock together.

Crostley said, "I'm most proud of how that one came out. Because I wasn't sure how it was going to look. And there's still minor things we have to do."

The boys are hoping they can patent their idea making it an invention while also making it affordable for schools and businesses.

"Our school just purchased door jammers that just slip on here and block it. They paid 80 dollars a piece for them." Brazil said, "We're hoping to cut that price in half and make these more affordable for schools to own."

Brazil said mass production of these could only take a couple minutes a piece, and installations for the hydraulic locks could take half an hour. These boys will be presenting their potentially life-saving designs at the SkillsUSA competition in Hershey.
