Our Story
About Princeton Pro Locksmith
A local, licensed locksmith serving Princeton and surrounding communities for over 35 years.
Our Story
Built on Trust, One Lock at a Time
Princeton Pro Locksmith was founded in 1989 by Henry Lione, a New Jersey-licensed locksmith who grew up in Mercer County and wanted to bring honest, reliable service to the community he knew. What started as a one-van operation has grown into a trusted local team — but the values haven't changed.
We're not a national call center that dispatches whoever is closest. Every technician on our team is personally vetted, background-checked, and trained in-house. When you call us, you get a Princeton-area professional who knows the neighborhoods, the housing stock, and the locks that are common here.
Over 35 years, we've helped more than 500 Princeton homeowners — from late-night lockouts to full security overhauls. We're proud of every five-star review, but what we're most proud of is the customers who call us back when they move to a new house or refer us to a neighbor.
