Farmingdale, New York — Summit Access & Security (formerly IML Security), a leading provider of comprehensive security solutions and physical security integration, has announced its acquisition of McCausland Lock Service of Prospect Park, Pennsylvania. The addition gives Summit a long-established storefront in Delaware County, deepens its reach across Greater Philadelphia, and opens Summit’s full range of access control and physical security services to McCausland’s customers.

McCausland is Summit’s third acquisition in 2026, following Top Security Locksmiths of Point Pleasant, NJ, and Monaco Lock Company of Jersey City, NJ, extending service from Maine to Virginia.

Led by Tom McCausland, a fifth-generation locksmith, and his daughter Chrissy, McCausland Lock Service is known for residential, commercial and automotive locksmithing, from car key programming and master key systems to panic bars, mag locks and hard-to-find “challenge” keys.

“McCausland’s has earned the trust of the Philadelphia community one customer at a time, and that doesn’t happen by accident or overnight,” said Sean O’Hayre, CEO & President of Summit Access & Security. “Tom and Chrissy have built a business their customers trust and their team is proud of—and that’s exactly what we stand for at Summit Access & Security. We’re thrilled to have the whole McCausland team join Summit, and the best is still ahead!” 

Tom McCausland will remain involved during the transition, working alongside Summit to ensure continuity for customers and employees. Chrissy and the entire McCausland team, including its technicians, have joined Summit as employees.

The retail shop at 1101 Lincoln Avenue in Prospect Park will continue offering automotive key and fob programming, hardware and security products.

“My family has been working with this community for generations, and our customers are our neighbors,” said Tom McCausland. “Joining Summit means our team and our shop stays right here on Lincoln Avenue. The people who count on us now get a lot more under one roof, from the same faces they already know.”

The acquisition also expands the services available to McCausland’s existing customers, who will now have access to Summit’s broader capabilities, including AAADM-certified automatic door systems, safes and vaults, commercial door hardware, access control, CCTV and video surveillance. As Summit employees, the McCausland team gains access to Summit's career pathways, from locksmithing into access control and safe and vault specialization, along with Summit's training, including management trainee and apprentice programs.
