Your door knob should turn smoothly every single time. No wiggling the handle, no jiggling to get it to latch, no wondering if it’ll hold up when someone tries to force it.
When door hardware fails, it’s not just annoying. It’s a security risk sitting in plain sight. A loose knob means the latch isn’t catching properly, and that’s an invitation you don’t want to extend.
Professional door knob installation means the hardware fits your door’s existing holes, the mechanism aligns with the strike plate, and everything operates the way it should. You’re not dealing with stripped screws, cracked faceplates, or a knob that falls off in your hand three weeks later. You get hardware that works today and keeps working.
We’ve been handling locksmith work since the late 1800s. That’s not a typo. Tom McCausland represents the fourth generation of his family in this trade, and his daughter Chrissy is learning it the same way he did.
We operate out of Prospect Park with mobile units positioned throughout Delaware County. Most Holme Circle calls get a response within 20 to 30 minutes because we’re already in the area.
The homes in Holme Circle were mostly built between 1940 and 1969. That means door frames with specific dimensions, older hardware configurations, and sometimes quirks that only show up when you’re actually doing the work. We’ve seen it before, and we know how to handle it without damaging your door or frame.
You call or message us with what you need. We ask a few questions about your door type, existing hardware, and what you’re looking to install. If you’re not sure, that’s fine—we can assess it when we arrive.
We show up with the tools and parts needed for the job. If you’ve already purchased hardware, we’ll work with what you have as long as it’s compatible with your door. If not, we carry OEM parts from Kwikset, Schlage, and Medeco in our mobile units.
The installation itself takes about 20 to 30 minutes for a standard door knob replacement. We remove the old hardware, check the door’s alignment and condition, install the new knob or lever, and test it to make sure the latch engages properly and the lock functions. If there’s an issue with fit or alignment, we address it before we leave. You shouldn’t have to call us back because something didn’t seat right.

Door knob installation covers more than just swapping out the visible hardware. We’re checking the bore hole diameter, the backset measurement, and whether your door can support the new hardware without modification. Holme Circle homes often have doors with 2-3/8″ or 2-3/4″ backsets, and using the wrong size means your latch won’t align with the strike plate.
We handle knobs, levers, deadbolts, and electronic locks. If you’re upgrading to a smart lock, we make sure it’s installed correctly with backup access options in case the electronics fail. A lot of people don’t think about that until they’re locked out because the batteries died.
If you need multiple doors done at once, we can handle that in the same visit. Rekeying, hardware replacement, and security upgrades all get done without requiring you to schedule separate appointments. You’re already taking time out of your day—we’re not going to waste it.
Door knob installation typically runs between $150 and $357 per door, depending on the hardware you’re installing and whether any modifications are needed. Basic knob or lever replacement on a standard door with existing holes falls on the lower end. Electronic locks, smart locks, or installations requiring adjustments to the door or frame cost more.
If you’re replacing multiple door knobs at once, the per-door cost usually drops because we’re already on-site with tools and materials. We’ll give you a clear price before starting any work so you know exactly what you’re paying.
The cost includes removal of old hardware, installation of the new knob or lever, alignment checks, and testing to make sure everything operates correctly. If we find an issue during installation—like a damaged door frame or misaligned strike plate—we’ll let you know what it’ll take to fix it before proceeding.
You can install a door knob yourself if you have the right tools, the hardware matches your door’s specifications, and you’re comfortable working with hand tools. The problem is that most DIY installations run into issues with alignment, backset measurements, or bore hole compatibility.
If the new hardware doesn’t match your door’s existing holes, you’ll need to drill or chisel out space for it. Do that wrong and you’ve damaged your door in a way that’s expensive to fix. If the latch doesn’t align with the strike plate, your door won’t close properly, and you’ll be dealing with a security gap.
Hiring a residential locksmith means the job gets done without damaging your door, the hardware fits correctly, and you’re not spending your weekend troubleshooting why the latch won’t catch. For most people, the time saved and the peace of mind that it’s installed right makes professional installation worth the cost.
A standard door knob replacement takes about 20 to 30 minutes once we’re on-site. That includes removing the old hardware, installing the new knob or lever, and testing it to make sure it operates smoothly.
If there are complications—like a door that’s warped, a frame that’s out of alignment, or hardware that doesn’t fit the existing holes—it can take longer. We’ll let you know if we run into something that’s going to add time to the job.
Installing electronic or smart locks takes a bit longer because there’s wiring, calibration, and programming involved. You’re looking at 45 minutes to an hour for those. If you’re having multiple doors done at once, we can usually work through them efficiently without dragging the appointment out longer than necessary.
A door knob is round and requires you to grip and twist it to operate the latch. A door lever has a handle you push down, which takes less hand strength and dexterity. Levers are easier to use if you have mobility issues, arthritis, or you’re frequently carrying things and need to open the door with your elbow.
Building codes in some areas require levers instead of knobs for accessibility reasons, especially in commercial spaces. For residential use, it’s usually a matter of preference and convenience.
Both knobs and levers come in keyed and non-keyed versions. Both can be paired with deadbolts for added security. The installation process is similar, though levers sometimes require slightly different strike plate positioning because of the way the latch mechanism operates. We handle both, and we can walk you through which option makes the most sense for your situation.
Yes. We install smart locks, electronic deadbolts, keypad entry systems, and other electronic door hardware. The installation process is more involved than a standard door knob because you’re dealing with batteries, wiring, and sometimes integration with your home’s Wi-Fi or security system.
The key with smart locks is making sure there’s a backup access method. If the batteries die or the electronics fail, you need a way to get in. Most smart locks have a physical key override, but not all of them. We’ll make sure you understand how your backup access works before we leave.
We also test the lock’s connectivity and programming to make sure it’s communicating with your phone or control panel correctly. A lot of people install these themselves and run into issues with pairing, range, or firmware updates. We handle that setup so you’re not troubleshooting tech problems when you just want to lock your door.
Door hardware typically needs replacement every seven years or so, depending on how much use it gets and whether it’s exposed to weather. Exterior door knobs wear out faster than interior ones because they’re dealing with temperature changes, moisture, and more frequent use.
If your door knob is loose, sticking, or the lock isn’t engaging properly, don’t wait for it to fail completely. A malfunctioning lock is a security risk, and a loose knob usually means internal components are wearing out. Replacing it before it breaks completely saves you from dealing with a lockout or a forced entry situation.
You should also replace door hardware if you’ve recently moved into a home, even if the knobs look fine. You don’t know who has keys to the old locks, and rekeying or replacing the hardware is the only way to be sure you’re the only one with access.
