McCausland Lock Service has been cutting keys and solving lock problems since the late 1800s. We’re not newcomers trying to figure things out—we’re the fourth generation of locksmiths who’ve been serving Delaware County families for over 140 years.
Tom McCausland and his daughter Chrissy run the largest locksmith operation in the Delaware Valley from our Prospect Park storefront. We’ve handled everything from simple house key copies to complex security installations, always with the same commitment to doing the job right.
Elwyn residents choose us because we understand the value of quality work. When you live in a community where homes average over $500,000, you want locksmith services that match that standard of excellence.
Bring your original key to our Prospect Park storefront. We examine it to determine the best blank and cutting approach for your specific lock type.
Our precision key-cutting equipment uses your original as a template, ensuring each cut matches exactly. We test every duplicate to make sure it turns smoothly and operates your lock properly before you leave.
Most residential key duplication takes just minutes. You can wait while we work, browse our security products, or handle other errands knowing your keys will be ready when you return. We cut everything from standard house keys to those “hard to find” keys that other places can’t handle.

Our residential key duplication service covers all standard house keys, deadbolts, patio door keys, and window keys. We stock blanks for major manufacturers like Kwikset, Medeco, and Schlage, plus specialty blanks for older or unique locks.
Elwyn’s mix of vintage 1940s homes and newer construction means you might have locks that require specific blanks or techniques. We’ve seen it all and stock accordingly. From antique skeleton keys to modern high-security residential locks, we duplicate keys that work reliably.
Every duplicate gets tested before you leave. We use the same precision standards whether you’re copying one key or a dozen. No job is too small, and we actually enjoy those challenging keys that make other shops shake their heads.
Most house key duplication takes just a few minutes at our Prospect Park storefront. Simple residential keys are typically ready while you wait.
More complex keys or specialty blanks might take slightly longer, but we handle the majority of residential key duplication requests immediately. We keep extensive blank inventory specifically to avoid delays, and our location is convenient for Elwyn residents.
If you’re making multiple copies or have several different keys to duplicate, plan for about 10-15 minutes total. We’ll give you an accurate time estimate when you arrive.
Yes, we specialize in keys for older homes. Since many Elwyn properties were built in the 1940s and 1960s, we regularly work with vintage lock hardware and unusual key types.
We stock blanks for older lock manufacturers and have the experience to handle keys that newer shops might not recognize. Our five generations of locksmithing experience means we’ve seen virtually every type of residential key.
Whether your home has original hardware from the 1940s or you’ve discovered an old key in a drawer, bring it in. We love the challenge of duplicating “impossible” keys, and we usually succeed where others fail.
That won’t happen with our key duplication service. We test every key before you leave to ensure it operates your lock smoothly and completely.
Our precision cutting equipment and quality blanks produce keys that work like originals. We use OEM-quality materials and techniques perfected over 140+ years of locksmithing experience.
If you ever have an issue with one of our duplicated keys—which is extremely rare—bring it back immediately. We stand behind our work and will make it right. Your satisfaction and security are our priorities.
Yes, we handle high-security residential key duplication for authorized key holders. These keys require special blanks and cutting techniques that most shops can’t provide.
High-security keys often have restricted duplication policies, so you’ll need to provide proper authorization. We’re authorized dealers for major high-security lock manufacturers and follow all required protocols.
If you’re unsure whether your keys are high-security, bring them in. We can identify the key type and explain your duplication options. Some high-security keys require factory authorization, which we can help coordinate.
Basic house key duplication is very affordable, typically much less than what you’d pay at big box stores or dealerships. Pricing varies based on key type and blank requirements.
Standard residential keys are our most economical service. Specialty keys, high-security blanks, or unusual key types may cost more due to material and time requirements.
We provide upfront pricing before starting any work. No surprises, no hidden fees. Most Elwyn residents find our prices fair and our quality superior to alternatives in the area.
In many cases, yes. We can create keys from locks when originals are lost, though this requires bringing the lock cylinder to our shop or scheduling a service call.
This process is more complex than simple duplication and requires removing the lock cylinder so we can determine the proper key cuts. It’s particularly useful for homeowners who’ve lost all copies of a key.
For Elwyn residents, we offer both in-shop services and mobile calls depending on your situation and lock type. We’ll assess your specific needs and recommend the most cost-effective solution.
