McCausland Lock Service has been solving key problems for Delaware County families since the late 1800s. We’re not some fly-by-night operation—we’re the fourth generation of the same family, still serving your neighbors from our Prospect Park shop just minutes from Garnet Valley.
Tom McCausland and his daughter Chrissy run the largest locksmith operation in the Delaware Valley today. When your great-grandparents needed keys cut, they probably came to us. When your kids need keys cut, they’ll come to us too.
We’ve seen every type of key, lock, and security challenge you can imagine. That experience means we can cut keys other places can’t handle, and we do it right the first time.
You bring us your original key—that’s it. We examine the key to determine the right blank and cutting method. Most house keys are cut within minutes using our precision equipment.
For standard residential keys like Kwikset and Schlage, the process is straightforward. We select the correct key blank, secure it in our cutting machine, and create an exact duplicate following your original key’s pattern.
Before you leave, we test every key we cut to make sure it works properly. If something’s not right, we fix it immediately. You walk out with keys that work perfectly in your locks, guaranteed.

Standard house keys are just the beginning. We cut keys for mailboxes, padlocks, older homes with vintage locks, and those “impossible” keys that big box stores turn away. Our key cutting covers everything from basic brass house keys to high-security restricted keys.
Garnet Valley homes often have unique security needs. Many properties in the area feature older architectural details with specialty locks, or newer construction with advanced security systems. We handle both ends of the spectrum with equal expertise.
Unlike automated kiosks that work maybe 70% of the time, our hand-operated precision equipment and experienced technicians ensure your duplicate keys work every time. We stock key blanks for virtually every residential lock manufacturer, including hard-to-find blanks for older or specialty locks common in Delaware County homes.
Basic house key duplication typically costs between $2-5 per key, depending on the type of key and blank required. Standard keys like Kwikset KW1 or Schlage SC1 are on the lower end of that range.
Specialty keys, vintage keys, or restricted keys cost more due to the specialized blanks and extra time required. We’ll give you an exact price when you bring your key in—no surprises or hidden fees.
Unlike some places that quote low prices then add charges for “premium” blanks or rush service, our pricing is straightforward. The price we quote is what you pay.
Yes, frequently. We regularly cut keys that hardware stores, big box retailers, and automated kiosks couldn’t handle. Our four generations of experience and professional-grade equipment let us work with keys others turn away.
This includes worn keys, unusual shapes, older key styles, and keys with complex cuts. We have access to key blanks that retail stores don’t stock, and our technicians know techniques for working with challenging keys.
If we can’t duplicate your key—which is rare—we’ll tell you honestly and suggest alternatives like rekeying your locks to a new key system.
Most standard house keys are cut within 2-3 minutes. You can wait while we make your duplicates—no need to drop off and come back later.
More complex keys or multiple keys might take 5-10 minutes total. If you need several keys cut or have specialty keys that require extra attention, we’ll give you a realistic time estimate upfront.
We prioritize accuracy over speed, but our experience means we work efficiently. You’ll have working duplicate keys in hand quickly, without the quality shortcuts that lead to keys that don’t work properly.
Absolutely. We test every key we cut before you leave to ensure it works smoothly in your locks. If there’s any issue with a key we’ve duplicated, bring it back and we’ll remake it at no charge.
Our guarantee covers both the cutting accuracy and the quality of the key blank. We use genuine key blanks from reputable manufacturers, not cheap knockoffs that break or wear out quickly.
This guarantee is backed by our reputation in the community. We’ve been serving Delaware County families for over 140 years because we stand behind our work and make things right when issues arise.
Hardware stores work fine for very basic, standard keys if their machine is properly maintained and calibrated. The problem is you don’t know the condition of their equipment or the experience level of the person operating it.
We specialize in key cutting—it’s what we do all day, every day. Our equipment is maintained to professional standards, and our technicians have the experience to handle any issues that come up during the cutting process.
For anything beyond the most basic house key, or if you want to be certain your duplicate keys work properly the first time, professional locksmith service is worth the small price difference.
In many cases, yes. If you still have access to the lock, we can often create new keys by examining the lock mechanism itself or by using specialized techniques to determine the correct key cuts.
This process is more complex than standard duplication and takes longer, but it’s usually much less expensive than replacing the entire lock. We can also rekey your existing locks to work with new keys if that’s a better solution for your situation.
The exact approach depends on your specific lock type and situation. Bring us the lock or give us a call to discuss your options—we’ll find the most cost-effective solution for getting you back to having working keys.
