You’re not dealing with loose handles six months from now. The latch catches cleanly every time. Your doors close without that annoying rattle or gap that makes you wonder if you’re actually secure at night.
When door knob installation is done right, you don’t think about it. That’s the point. No stripped screws from forcing the wrong hardware into old holes. No misaligned strike plates that leave your door half-latched. No wondering if the lock will hold if someone actually tries it.
You get hardware that fits your door type, installed with the right tools and spacing. Whether it’s a standard passage knob for your hallway or a keyed entry set for your front door, everything lines up. The mechanism engages smoothly. The door closes flush. And if you ever need to rekey or upgrade down the line, the installation won’t be working against you.
We’ve been handling lock and door hardware work in Delaware County since the late 1800s. We’re now the largest locksmith operation in the Delaware Valley, and we’ve stayed in business this long because we show up when we say we will and we don’t create new problems while fixing old ones.
Tom McCausland and his daughter Chrissy run the operation today. They’re the fourth generation doing this work. That means we’ve seen every type of door, every outdated hardware setup, and every “I tried to install it myself” situation you can imagine in Media and the surrounding neighborhoods.
We’re local. Our shop is in Prospect Park. We stock parts from Kwikset, Schlage, and Medeco. And we’re not learning on your door—we already know how it’s supposed to work.
You call or message us with what you need—new door knobs, a full replacement, or a repair on hardware that’s not working right. We ask a few questions about your door type and what you’re dealing with so we know what to bring.
Our technician shows up with a fully stocked van. That means we’re not making a second trip for parts or realizing mid-job that your door needs a different backset. We assess the existing hardware, check the door alignment, and confirm what you actually need before we start removing anything.
Then we remove the old hardware, prep the door if needed, and install the new knob or lever set. We make sure the latch aligns with the strike plate, the door closes properly, and the lock engages without resistance. If you’re upgrading to a smart lock or keypad entry, we handle the full setup and make sure you know how to use it before we leave.
The whole process usually takes 30 minutes to an hour per door, depending on whether we’re working with existing holes or need to drill new ones. You’re not left with a door that doesn’t close right or hardware that feels loose from day one.
Ready to get started?
You’re getting more than someone with a drill. We bring the right parts, the right tools, and the experience to handle whatever your door throws at us—old wood that’s settled, misaligned frames, or previous installations that weren’t done correctly.
We install passage knobs, privacy locks, keyed entry sets, and lever handles. If you’re upgrading to smart locks or electronic deadbolts, we handle those too. We work with all the major brands and we stock OEM parts, so you’re not getting generic hardware that wears out in a year.
In Media, a lot of the homes we work on are older. That means door frames that have shifted, holes that don’t match modern hardware standards, and strike plates that need repositioning. We adjust for that. If your door needs a different backset or the bore hole is slightly off, we fix it so the new hardware fits correctly and functions the way it should.
You also get upfront pricing. No surprises when the job’s done. And if something’s not working right after we leave, we come back and make it right. That’s how we’ve stayed in business for over 140 years in this area.
Most door knob installations run between $150 and $250 per door, depending on the type of hardware and whether we’re working with existing holes or need to drill new ones. A basic passage knob in a standard door is on the lower end. A keyed entry set with a deadbolt or a smart lock installation is higher.
If you’re replacing all the door hardware in your house, we can usually give you a better per-door rate. The price includes the labor, any minor adjustments to the door or frame, and making sure everything’s aligned and working correctly before we leave.
What you’re paying for is avoiding the mistakes that cost more to fix later—stripped screws, misaligned latches, or doors that don’t close right because the hardware wasn’t installed at the correct height or backset. We bring the right tools and parts the first time, so you’re not dealing with a second trip or a door that never quite works the way it should.
Yes, in most cases. We keep our vans stocked with the most common door hardware and all the tools needed for standard installations. If you’re in Media or anywhere in Delaware County, we can usually get to you within a few hours, sometimes sooner depending on the day.
If you already have the door knobs or levers you want installed, we can work with those as long as they’re compatible with your door type. If you need us to supply the hardware, we’ll confirm what you need over the phone and bring the right parts with us.
The only time same-day service might not work is if you need a specialty lock or custom hardware that we don’t stock. In that case, we’ll let you know upfront and schedule a time once we have what you need. But for most residential door knob installations, we’re set up to handle it the same day you reach out.
A door knob is the traditional round handle you twist to open the door. A lever is the handle you push down. Both do the same job, but levers are easier to operate if you have your hands full or if anyone in your house has arthritis or limited grip strength.
For interior doors like bedrooms and bathrooms, either works fine. It’s mostly about preference and what matches the rest of your home. For exterior doors, levers are becoming more popular because they’re easier to use when you’re carrying groceries or have wet hands.
Building codes in some areas actually require levers for accessibility, especially in commercial spaces or new construction. In older Media homes, we see a mix. Some people stick with knobs to match the original style, others upgrade to levers for the convenience. We can install either, and we’ll make sure whichever you choose is the right grade for the door—passage, privacy, or keyed entry depending on where it’s going.
Most modern door knobs are designed to fit standard bore holes—that’s the large circular hole in the face of the door—and standard backsets, which is the distance from the edge of the door to the center of that hole. The two most common backsets are 2-3/8 inches and 2-3/4 inches.
If your home was built in the last 50 years, there’s a good chance new hardware will fit without any modifications. If your house is older, like a lot of homes in Media, the existing holes might be slightly different or the door might have settled in a way that affects alignment.
That’s where having someone who knows what they’re doing matters. We measure first. If the holes don’t match, we can either find hardware that fits your existing setup or modify the door to accept the new hardware. We’re not forcing something to fit and leaving you with a door that doesn’t latch correctly. We make sure the new knob or lever works with your door as it is, or we adjust the door so it works with the hardware you want.
Yes. We install all the major smart lock brands—August, Schlage Encode, Kwikset Halo, Yale Assure, and others. Whether it’s a Bluetooth lock you control from your phone or a keypad deadbolt with a physical code, we handle the full installation and setup.
Smart locks require a little more than standard door knob installation. The door needs to be properly aligned so the electronic mechanism doesn’t bind or drain the battery faster than it should. We make sure the strike plate is positioned correctly and the door closes flush so the lock engages smoothly every time.
We also walk you through how to use it before we leave—how to add and remove user codes, how to connect it to your phone or home system, and what to do if the battery dies. Most smart locks have a backup option, either a physical key or an external battery terminal, and we’ll show you where that is and how it works. You’re not figuring it out on your own after we’re gone.
If you’re dealing with one broken knob and everything else works fine, there’s no reason to replace them all. But if multiple knobs are starting to feel loose, stick, or show wear, it makes sense to do them all at the same time. You’ll get a better rate on labor, and all your hardware will match and function consistently.
The other reason to replace everything at once is security. If you just moved into a home in Media, you don’t know who has keys to your old locks. Replacing or rekeying all your entry door hardware means you’re starting fresh. Even if the knobs look fine, you don’t know how many copies of those keys are floating around.
We also see people replace all their interior door knobs when they’re updating the style of their home. If you’re going from brass to brushed nickel or from knobs to levers, doing it all at once gives you a cohesive look. We can knock out a whole house in a few hours, and you’re not living with mismatched hardware while you decide what to do with the rest.
