Mt. Greenwood Pride 2020

With the COVID-19 pandemic, it’s been a busy time for Chicago Lock Box and its staff—just ask Elizabeth Mannix Gajos, who has been helping customers at Chicago Lock Box for 18 years.

Elizabeth and her staff have helped customers at Chicago Lock Box LLC, 3400 W. 111th St., accomplish the tasks on their busy schedule—even in trying times—and it has thrived for more than 30 years.

Elizabeth knows busy. She’s a mother of three who earned a master’s degree in 2017 and is now a school counselor at a suburban alternative school.

With being so busy, she knows the one thing that Chicago Lock Box customers love to hear: “Don’t worry. We’ll take care of everything!”

In a word, Elizabeth and her staff help folks get stuff done. Whether it’s shipping with UPS or FedEx, providing private mailboxes or doing color printing and binding, Elizabeth and her staff provide unmatched personal service.

That personal touch has earned strong loyalty from the hundreds of longtime customers at Chicago Lock Box.

As a family-owned small business, Chicago Lock Box has survived the economic challenges of the nation’s economy by doubling down on what it knows best.

“We just increased our level of service,” Elizabeth said. “If people ask us to do something, we do it.”

Along with staff members Patty, Lorena, Kathleen and Jackie, Elizabeth is proud to provide the Mt. Greenwood community with friendly service that gets every job done right.

“We know our customers,” said Elizabeth. “Some of my customers come in to check their mailbox, and I’ll have the mail waiting for them because I recognized their car when they drove up.”

With its business services and private mailboxes, Chicago Lock Box is like a mini corporate headquarters for small businesses and entrepreneurs. Its private mailboxes are convenient, affordable and secure.

Chicago Lock Box’s services for business customers have grown over the years. Its color printing/copying and binding services are perfect for professionals who need expert-looking presentation documents.

In addition, local businesses also have a convenient and reliable local resource for sending and receiving faxes, public notary service, and printing out large documents such as contracts.

“I had someone come in who was writing a book,” Elizabeth said. “We printed out the first copy for him on our printer; now’s it’s a published book, and he gave us a signed copy that said, ‘My first publisher.’”

People can also buy 500 business cards for only $40 at Chicago Lock Box. Just stop in and the staff will help you design a great-looking business card at a price that can’t be beat.

Chicago Lock Box is family owned and operated. Hard work and personal service was the motto of the late John Mannix, who owned the firm for years until his death in 2006. Now John’s daughter, Elizabeth, her husband, Brian Gajos, and her brother, Thomas Mannix, carry on that tradition. There’s even another generation coming up, and on certain days, customers also get a cheerful greeting from the next generation at Chicago Lock Box: Elizabeth’s kids, Maya,12, Quinn, 8, and Lucas, 6.

For shipping packages, Chicago Lock Box can’t be beat. It is an authorized FedEx and UPS shipping outlet and offers packaging and wrapping of items to be shipped.

The firm also offers FedEx and UPS receiving service as well as some USPS services for one-stop shopping. Packaging supplies such as tape, bubble wrap and boxes are also available.

Chicago Lock Box can make mail-order and Internet shopping more convenient by enabling customers to send their packages to the store for pickup at their convenience, avoiding the hassle of waiting at home for a delivery to arrive.

With many airlines charging for luggage, the unique “Avoid the Airport Hassle, Ship Your Luggage” program saves travelers and vacationers time and money. Even better, by shipping their luggage with Chicago Lock Box, they avoid the hassles of dealing with airport baggage pick-up.

Another innovative service is “Ship Your Student to College,” where Chicago Lock Box ships a student’s belongings directly to school. Parents have found this service extremely useful when taking their kids to college because it reduces or eliminates the need to rent a truck or trailer, or take two vehicles.

Chicago Lock Box is proud to support American troops with a free service that helps residents send love to the troops.

“Although we are not able to ship directly to service personnel—the post office is the only way to ship to APOs and FPOs—we would like to do our part to support our troops,” Elizabeth said. “Just bring in the items for your care package, and we will donate a box and the packing to get it ready to send. We will also include a label, all at no charge to you.”

Chicago Lock Box has also been active in supporting the community. Elizabeth is on the board of directors of the Mt. Greenwood Community and Business Association. In addition, the firm supports include Hope Children’s Hospital. It is a Mt. Greenwood Lions eyeglasses drop-off location and is a “Peanut Recycling Location” with the Plastic Recycling Council.
