You’re not looking for the cheapest option. You want door knobs and levers that turn smoothly, latch properly, and don’t need adjusting three months later.
That’s what proper installation gets you. The right measurements from the start. Hardware that matches your door thickness and hole pattern. Alignment that doesn’t bind or stick when you’re carrying groceries or letting the dog out.
We handle everything during one visit—installation, rekeying if you need it, and making sure your new hardware integrates with your existing locks. You get hardware that works the way it’s supposed to, installed by someone who’s done this a few thousand times. No learning curve on your dime.
McCausland Lock Service has been in the same family since the late 1800s. We’re the largest locksmith company in the Delaware Valley, and we’ve worked on just about every type of home you’ll find in Saint Davids—from the Tudor and Queen Anne homes near the historic district to newer construction in Radnor Township.
We know Main Line architecture. We stock hardware that actually complements your home instead of looking like an afterthought. Our techs show up in fully equipped mobile workshops, usually within 20 to 30 minutes for emergency calls, with the parts and tools to finish the job that day.
You call, we dispatch the closest technician to Saint Davids. We typically arrive within 20 to 30 minutes if it’s urgent, or we schedule a time that works for you.
Once on-site, we assess what you’re working with—door thickness, existing holes, whether you’re replacing old hardware or installing fresh. We explain what needs to happen, what it’ll cost, and how long it takes. No surprises.
Then we install your new door knobs or levers using manufacturer-approved methods and OEM parts. We check alignment, test the latch, and make sure everything operates smoothly. If you want rekeying done at the same time, we handle that too. Most installations wrap up in under an hour, and you’re left with hardware that actually works.
Ready to get started?
We bring the hardware or install what you’ve already purchased. Either way, you get proper measurement, correct boring if needed, and installation that meets manufacturer specs.
For Saint Davids homes—especially the historic properties with unique door styles—we make sure your new hardware fits the character of your home. That means matching finishes, understanding period-appropriate styles, and knowing which modern options blend in without looking out of place.
We also handle the technical side: rekeying your new locks to match your existing key, programming smart locks if you’re upgrading to keyless entry, and integrating everything with your current security setup. You’re not stuck with five different keys or a system that doesn’t talk to itself. We stock Kwikset, Medeco, and Schlage, so if you need authorized service or specific parts, we’ve got them on the truck.
Installation typically runs between $150 and $357 per door, depending on the hardware you choose and whether you need additional work like rekeying or boring new holes. Labor rates in the area range from $37 to $190 per hour.
If you’re replacing existing hardware with a direct fit, you’re looking at the lower end. If we’re installing new hardware that requires different hole patterns or upgrading to smart locks that need programming, it’ll be higher.
We give you an exact price before we start. No hourly guessing games. You’ll know what it costs to get the job done right, and you can decide if it makes sense for your situation.
Yes. Saint Davids has some of the best-preserved historic architecture on the Main Line—Tudor, Second Empire, Queen Anne styles dating back to the late 1800s. We’ve worked on plenty of them.
We stock and source hardware that complements period homes without compromising modern security standards. That means finishes and styles that don’t look like they came from a big-box store, but still give you the durability and functionality you need in 2025.
If you’ve got specific requirements—matching existing finishes, maintaining historical accuracy for a restoration, or blending modern smart lock tech into older doors—we’ll walk through your options and show you what actually works for your home’s style and your security needs.
Yes. We run a mobile fleet across Delaware County, and our dispatch system identifies the closest technician to your location in Saint Davids. For emergency calls—like you’re locked out or need immediate access restored—we typically arrive in 20 to 30 minutes.
For scheduled installations, we work around your timeline. Most door knob and lever installations take under an hour once we’re on-site, so you’re not losing your whole day.
We carry common hardware and parts on every truck, which means we can usually complete the job during the first visit. If you’ve ordered specific hardware or need something custom, we’ll coordinate timing so everything’s ready when we arrive.
Functionally, they’re similar—both latch your door and provide security. The main difference is operation: knobs require a twisting grip, levers use a downward push.
Levers are easier to operate if you’ve got your hands full or deal with arthritis. They’re also becoming the preferred choice in 2025 design trends for their ergonomic benefits and cleaner aesthetic lines.
Installation process is nearly identical. Both require proper boring, correct backset measurement, and alignment so the latch engages smoothly. We install both types regularly in Saint Davids homes, and we can walk you through which option makes more sense for your doors, your household needs, and your home’s style. If you’re upgrading, we’ll also discuss finishes and smart lock compatibility.
Yes, and most people do. If you’re installing new door knobs, it makes sense to rekey them so they match your existing house key. Otherwise you’re juggling multiple keys every time you come home.
We handle rekeying on-site during the same visit. It adds minimal time to the appointment, and you walk away with new hardware that works with the key you’re already carrying.
If you’re concerned about security—maybe you just bought the home or you’ve had contractors in and out—we can also rekey your entire house at once. That way, old keys no longer work, and you control who has access. It’s faster and cheaper than replacing all your locks, and it gives you the same security reset.
Yes. Smart locks and biometric entry systems are becoming standard in higher-end Saint Davids homes, and we install and program them regularly.
We work with the major brands—Kwikset, Schlage, Medeco—and we’re authorized dealers, so you’re getting manufacturer-approved installation and warranty protection. We’ll integrate your new smart lock with your phone, set up access codes, and make sure it communicates properly with your home security system if you have one.
If you’re upgrading from traditional locks, we’ll also explain how the system works, walk you through the app, and answer questions about battery life, backup key access, and remote monitoring. The goal is to get you set up with technology that actually makes your life easier, not more complicated.
