About Arapahoe Security

In a word, we are skilled progressive helpful .

We pride ourselves in caring for our customers by partnering with them, forming long-term relationships and becoming part of how our customers do business year after year.


Who We Are

The early years looked very different from today. Working out of their home with only one truck and one phone line, Paul and Sheila Rossman had a vision that carried them through many lean years—and still operate by that vision today.

ACSC is still growing and we couldn't do it without our outstanding staff. Our outside in-the-truck technicians, shop personnel and support staff all maintain the same core belief—give customers the highest quality service, charge a fair rate and do excellent work every time.

Maybe that's why, since 2009, ACSC is the only locksmith and security company in Aurora with a real "bricks and mortar" storefront location. We are good at what we do and we love what we do.

27 years in business

We are still going strong and proud to have the confidence and trust of our customers for all this time. Thank you Colorado!

Loved by customers

And we love our customers too. In fact, we have been partnering with some of our customers since our first year in business.

Part of the community

Since we have a storefront location, our customers know we are a real company they can trust. Now that's important.
