Family Locksmith Upper Darby PA

Four Generations of Getting It Right

The McCausland family has been locksmithing since the late 1800s. Today, Tom McCausland and his daughter Chrissy run the largest locksmith operation in the Delaware Valley from our Prospect Park storefront.

We’re not some fly-by-night operation that showed up yesterday. Upper Darby families have been trusting us with their security for over 140 years because we show up when we say we will, we fix things right the first time, and we don’t try to sell you stuff you don’t need.

You’ll find us at our shop on Lincoln Avenue, where we can cut your keys while you wait and show you security products in person. But most of our work happens in your driveway, at your office, or wherever you’re locked out and need help fast.
