When your door knob is installed right, you don’t think about it. It turns smoothly every time. The latch catches without forcing it. The lock engages without wiggling the handle.
You’re not dealing with loose screws three months later. You’re not calling someone back because the alignment’s off or the strike plate wasn’t set correctly. You’re not standing there jiggling a handle that should just work.
That’s what happens when someone who knows what they’re doing handles the measurements, the boring, the mortising, and the hardware setup. Your door closes flush. Your deadbolt slides without resistance. Everything lines up because it was done with the right tools and enough experience to catch problems before they become your problems.
We’ve been doing locksmith work since the late 1800s. Tom McCausland learned from his father, who learned from his father, who learned from Charles McCausland Senior. That’s four generations of figuring out what works, what doesn’t, and how to fix it when someone else got it wrong.
We run the largest locksmith operation in the Delaware Valley from our Prospect Park storefront. That means we stock the parts you actually need—Kwikset, Schlage, Medeco—and we don’t have to order them or make you wait. We’ve been serving Delaware County families, including Lenni homeowners, long enough that we’re working on houses we first keyed decades ago.
You’re not getting a call center or a subcontractor. You’re getting someone who’s been doing this work their entire career, in the same area, for the same kinds of homes you live in.
First, we look at what you’ve got. Old knob, new door, retrofit situation—it matters because the prep work changes. If the door’s already bored and mortised, we check the measurements. If it’s a new install, we measure twice and drill once.
We bore the holes to the exact diameter your hardware needs. We chisel the mortise for the latch plate so it sits flush with the door edge—not proud, not recessed. We install the strike plate on the jamb so the latch actually catches when the door closes. These aren’t complicated steps, but they’re easy to mess up if you’re rushing or guessing.
Once the knob or lever is mounted, we test it. Does it latch without forcing the door? Does it turn without binding? Does the deadbolt slide smooth? If something’s off, we adjust it before we leave. You shouldn’t have to live with a door that doesn’t close right or a lock that fights you every time you use it.

You get the labor and the hardware. We bring OEM parts—the manufacturer-approved stuff that’s built to last—so you’re not replacing everything again in two years. That includes the knob or lever, the latch assembly, the strike plate, and the screws that actually hold it all together.
If you’re in Lenni and you’ve got one of the older homes common to Delaware County, we’ve worked on plenty like it. Doors that aren’t perfectly square, jambs that have settled, frames that need a little extra attention to get the hardware sitting right. We adjust for that. We’re not forcing standard hardware into a non-standard opening and calling it done.
We also handle lever installation and lever repair if you’re switching from knobs to levers for accessibility or just because you prefer them. Same process, same attention to getting the mechanics right. And if you’re a new homeowner, we’ll rekey your locks while we’re there so you’re the only one with a working key. No guessing who else might have a copy from the previous owner.
You’re typically looking at $80 to $357 per door, depending on the hardware you choose and what the door needs. A straightforward swap on a prepped door with standard hardware sits on the lower end. A full install on a new door with higher-end locks and deadbolts runs higher.
We don’t charge you for things you don’t need. If your door’s already bored and mortised correctly, we’re not re-doing work that’s fine. If it needs adjustment or new prep, we’ll tell you why and what it costs before we do it.
The price includes labor and materials—the knob or lever, the latch, the strike plate, and installation. We use OEM parts from Kwikset, Schlage, or Medeco depending on what you’re installing, so you’re getting hardware that’s actually going to hold up.
Levers are easier to operate, especially if you’re carrying something or dealing with arthritis or limited hand strength. You don’t have to grip and twist—you just push down. That’s why a lot of Lenni homeowners are making the switch, particularly on frequently used doors like the one from the garage or the back door.
Levers also tend to look more modern. If you’re updating your home’s appearance or prepping to sell, swapping out old knobs for clean lever hardware makes a noticeable difference without a major renovation.
The installation process is nearly identical to a knob. Same boring, same mortising, same latch assembly. The only real difference is the lever mechanism, and we handle that the same way we handle knobs—measure correctly, install it flush, make sure it operates smoothly before we leave.
Yes. We install electronic locks and smart deadbolts on a regular basis. The process is similar to standard hardware, but there’s more to it—battery compartment placement, wiring if it’s connected to your system, making sure the electronic components fit the door thickness and don’t interfere with the latch mechanism.
A lot of smart locks fail because they weren’t installed with the door’s actual dimensions in mind. The bolt doesn’t align right, or the sensor doesn’t register when the door’s closed, or the whole thing drains batteries because it’s working too hard to latch. We avoid that by measuring everything first and testing it thoroughly before we’re done.
If you want keyless entry or remote access or integration with your home system, we’ll set it up so it actually works the way it’s supposed to. You’ll still get a physical key option on most models, which is smart in case the battery dies or the system glitches.
Loose knobs usually mean the screws have stripped out, the bore hole is oversized, or the hardware wasn’t tightened correctly in the first place. We can tighten what’s salvageable, but if the door’s damaged or the holes are wallowed out, we’ll need to repair the door or use hardware with a larger plate to cover the problem area.
If it’s not latching, the issue is usually alignment. Either the strike plate is positioned wrong, the door has sagged, or the latch itself is worn out. We check the gap between the door and the jamb, adjust the strike plate if needed, and replace the latch assembly if it’s shot.
This is common in older Delaware County homes where settling has shifted the door frame slightly over the years. It’s fixable, but it takes someone who knows how to read the door and make the right adjustments instead of just forcing the hardware to fit.
Yes. You don’t know who has keys. The previous owner might have given copies to family, neighbors, contractors, dog walkers, or house sitters. Even if they handed you every key they had, there’s no way to know if someone made a spare and forgot about it.
Rekeying changes the internal pins so the old keys don’t work anymore. You get new keys, and you’re the only one who can get in. It’s faster and cheaper than replacing all the locks, and it gives you the same result—control over who has access.
We can rekey your locks when we’re installing or replacing door knobs. If you’ve got multiple exterior doors, we can also set them up on the same key so you’re not juggling a ring full of different keys just to get into your own house. It’s a simple step that makes a real difference in your peace of mind, especially right after you move in.
A standard replacement on a door that’s already prepped takes about 30 minutes per door. If we’re boring new holes, cutting a mortise, or dealing with alignment issues, it might take an hour or a bit more depending on what the door needs.
We’re not rushing through it. The goal is to get it right so you don’t have problems later. That means checking measurements, making sure everything’s flush and aligned, testing the operation, and adjusting anything that’s not smooth before we pack up.
If you’re having multiple doors done or adding deadbolts and rekeying, we’ll give you a realistic timeframe when we look at the job. Most residential locksmith work in Lenni is straightforward, but older homes sometimes throw a curveball, and we’d rather take the extra time to handle it correctly than leave you with hardware that doesn’t work right.
