You walk up to your door after work, groceries in hand, and your key slides in perfectly. No jiggling, no forcing, no standing there frustrated while your ice cream melts. That’s what happens when you get your keys duplicated by professionals who’ve been perfecting this craft for over 140 years.
Most people wait until they’re locked out to think about spare keys. Smart homeowners in Marple get ahead of the problem. You’ll have reliable backups for family members, hide-a-key situations, or that inevitable moment when your main key decides to break off in the lock.
Quality key duplication means you’re not calling a locksmith at 11 PM because your teenager lost their key again. You’re not explaining to your boss why you’re late because you couldn’t get in your house to grab your work bag. You’re just living your life, with one less thing to worry about.
McCausland Lock Service has been cutting keys since the late 1800s. We’re not some fly-by-night operation that learned locksmithing from YouTube videos. Tom McCausland and his daughter Chrissy represent the fourth generation of locksmiths serving Delaware County families.
Our Prospect Park storefront is the largest locksmith operation in the Delaware Valley. When Marple residents need reliable key duplication, they know where to find us. We’ve seen every type of key, every brand of lock, and every security challenge you can imagine.
Local families trust us because we’ve earned it over more than a century. We’re the locksmith your great-grandfather might have used, and we’re still here because we do the work right.
Bring your original key to our Prospect Park shop. We examine it to determine the best cutting approach, especially for worn or specialty keys. Our professional-grade equipment creates an exact duplicate that works smoothly from day one.
Most residential key duplication takes just minutes. We test every key before you leave to ensure it operates your lock perfectly. No guesswork, no “try it and see” approach.
For specialty keys or high-security locks, we use manufacturer specifications and OEM materials. You’re not getting a cheap copy that might work for a few weeks. You’re getting a properly cut key that will serve you for years.

We duplicate house keys, mailbox keys, garage door keys, and those tricky specialty keys other places can’t handle. Our equipment works with Kwikset, Schlage, Medeco, and other major lock manufacturers that Marple homeowners rely on.
Delaware County homes built in different eras use different key systems. Older homes might have unique key profiles that require special attention. Newer constructions often use high-security keys with specific cutting requirements. We handle both with equal expertise.
You’ll also find us stocked with quality key blanks, not the bargain-bin versions that wear out quickly. When you need duplicates of keys for safes, filing cabinets, or other security items, we have the materials and knowledge to get it done right.
Most residential key duplication takes just a few minutes at our Prospect Park location. We cut your key, test it to ensure proper operation, and you’re ready to go. The actual cutting process is quick, but we take time to examine your original key first, especially if it shows wear or has an unusual profile.
For specialty keys or high-security locks, the process might take slightly longer as we ensure we’re using the correct specifications and materials. We’d rather spend an extra few minutes getting it perfect than have you come back because the key doesn’t work properly.
We duplicate standard house keys, deadbolt keys, mailbox keys, garage door keys, and most specialty residential keys. Our equipment works with major manufacturers like Kwikset, Schlage, and Medeco that are common in Marple homes.
We can also handle older or unusual key profiles that other places might not be able to cut. Our four generations of experience mean we’ve encountered virtually every type of residential key system used in Delaware County. If you have a key that’s been difficult to duplicate elsewhere, bring it to us.
Absolutely. We test every key before you leave our shop to ensure it operates your lock smoothly. If a key we cut doesn’t work properly, we’ll recut it at no charge or refund your money.
Our professional-grade equipment and quality materials mean problems are rare, but we stand behind our work completely. We’ve been serving Delaware County families for over 140 years by doing the job right the first time and making it right if something goes wrong.
Basic residential key duplication is very affordable, typically just a few dollars per key. Specialty keys or high-security locks may cost slightly more depending on the complexity and materials required.
We provide upfront pricing with no hidden fees or surprise charges. Unlike some places that quote low prices then add fees, our price is our price. We believe in honest, straightforward pricing that respects your budget and your time.
In most cases, we need the original key to create an accurate duplicate. However, for situations where you’ve lost all copies, we can often create new keys by working directly with your locks, though this is a more complex process.
If you’re completely locked out with no keys available, we offer full locksmith services to regain entry and create new keys for your home. This situation requires on-site service rather than simple key duplication, but we handle these emergencies regularly for Marple area homeowners.
While our storefront operates during regular business hours, we understand that key emergencies don’t follow schedules. If you’re locked out and need immediate assistance, we provide emergency locksmith services throughout the Marple area.
For urgent situations, we can come to your location, regain entry to your home, and create new keys on the spot. Our mobile service includes the equipment needed to handle most residential lock and key emergencies without requiring multiple trips.
