You shouldn’t have to jiggle your door knob for two minutes every time you come home. You shouldn’t stand outside in the cold because your deadbolt decided to quit. And you definitely shouldn’t wonder if someone three owners ago still has a key.
Door knob replacement fixes those problems. New hardware means smooth operation, better security, and one less frustration in your day.
In Collingdale, where nearly half the homes were built before 1960, aging door hardware is common. Locks wear out. Mechanisms fail. What worked fine for decades stops working overnight. Professional installation means the job gets done correctly, with proper alignment and security features that actually protect your home.
You get hardware that turns smoothly, locks that engage properly, and keys that work without a fight. More than 30% of burglars walk right through the front door instead of breaking windows. Functional, secure door knobs matter.
The McCausland family has been doing locksmith work since the late 1800s. Tom McCausland runs our operation now, fourth generation, with his daughter Chrissy. We operate the largest locksmith company in the Delaware Valley from our fully stocked storefront in Prospect Park, just minutes from Collingdale.
That means real inventory, real technicians, and real accountability. No call centers. No subcontractors. When you call, you get someone who actually shows up when they say they will.
Collingdale families come back generation after generation because we get the work done right. OEM parts from manufacturers like Kwikset, Medeco, and Schlage. Professional installation that doesn’t damage your door or frame. Same-day service that typically arrives within 20 to 30 minutes for emergencies.
Our technician shows up with the parts and tools needed to complete the job in one visit. First step is assessing your existing door and hardware to determine what fits and what works with your door thickness, backset, and security needs.
If you’re replacing old hardware, the existing knob or lever gets removed carefully without damaging the door. The bore holes get inspected to make sure new hardware will fit properly. Sometimes older doors need minor adjustments for modern hardware to align correctly.
New hardware goes in with proper alignment so the latch engages smoothly and the lock functions without sticking. The strike plate gets positioned so the door closes securely without gaps. Everything gets tested to confirm smooth operation before we leave.
If you need rekeying at the same time, that happens during the same visit. If you want multiple doors done, we handle all of them without requiring a second appointment. The job gets finished completely, not partially.

Professional door knob installation covers the full scope of getting your door hardware working correctly. That includes removing old hardware, preparing the door for new components, installing the new knob or lever with proper alignment, and testing everything before we leave.
You get OEM quality parts, not cheap substitutes that fail in six months. The installation includes the interior and exterior hardware, strike plates, and all necessary mounting hardware. If you’re upgrading to smart locks or electronic keypads, the installation includes proper setup and programming so the technology actually works as intended.
In Collingdale’s housing stock, where many homes feature original doors from the 1940s through 1960s, installation sometimes requires adapting modern hardware to older door configurations. That might mean adjusting bore holes, reinforcing strike areas, or ensuring the new hardware accommodates the door’s thickness and swing.
The service also includes rekeying if needed, so your new hardware works with keys you control. No wondering who else might have access. Labor and materials typically run between $150 and $357 per door depending on hardware complexity, but you’re getting professional installation that eliminates security gaps and operational problems.
Most standard door knob installations take 20 to 30 minutes per door once our technician arrives. That includes removing your old hardware, installing the new components, and testing everything to make sure it works smoothly.
More complex jobs take longer. If you’re installing smart locks with electronic components, expect 45 minutes to an hour because programming and setup add time. If your door needs adjustments to accommodate new hardware, that extends the timeline.
Multiple doors in one visit actually save time overall because our technician is already on site with tools and parts ready. Three doors might take 90 minutes total instead of scheduling three separate appointments.
Yes, and that’s exactly what professional installation prevents. Older doors in Collingdale’s pre-1960s housing stock often have different dimensions than modern doors, but our experienced technicians know how to adapt new hardware without damaging original woodwork.
The key is understanding backset measurements, bore hole sizing, and strike plate positioning. Sometimes older doors have non-standard measurements that require specific hardware or careful modification. We assess what you have before starting work.
Damage happens when someone forces modern hardware into configurations that don’t match. Proper installation means measuring first, selecting compatible hardware, and making precise adjustments when necessary. You end up with functional new hardware and intact original doors.
Levers and knobs install similarly, but levers offer easier operation for people with arthritis, limited hand strength, or anyone carrying groceries. You can push a lever down with your elbow. Knobs require grip and twisting.
From an installation standpoint, both require the same bore holes and backset measurements. The main difference is the mechanism inside. Levers use a different spring and latch system that needs proper alignment to avoid sagging over time.
Building codes for commercial properties often require levers for accessibility compliance, but residential properties have more flexibility. If anyone in your household struggles with grip strength, levers make daily life easier. Installation cost is roughly the same for both.
You don’t have to, but it’s the smart time to do it. If you’re already replacing the hardware, rekeying during the same visit costs less than scheduling a separate service call later.
Rekeying makes sense when you don’t know who has keys to your home. In Collingdale’s housing market, where homes change hands and get passed down through families, previous owners, old tenants, contractors, and neighbors might have copies you don’t know about.
New hardware with fresh keys means you control access completely. We can key all your doors to work with the same key, which is more convenient than carrying multiple keys for different doors. It’s one less thing to worry about.
Yes, and proper installation matters even more with electronic locks because they need correct alignment to function reliably. Smart deadbolts and keyless entry systems have tighter tolerance requirements than traditional hardware.
The installation includes mounting the electronic components, ensuring the bolt aligns perfectly with the strike plate, programming your access codes, and connecting to your smart home system if applicable. Battery placement, sensor positioning, and wireless connectivity all get configured during installation.
Smart locks offer features like temporary codes for guests, activity logs showing who entered when, and remote access from your phone. But those features only work if the hardware is installed correctly. Deadbolt smart locks are projected to account for 42.7% of the market in 2025 because homeowners want the security of knowing their doors are never left unlocked.
Professional installation typically runs $150 to $357 per door, including labor and materials. That range depends on hardware complexity, whether you’re installing basic knobs or electronic smart locks, and if any door modifications are needed.
Basic knob or lever installation with standard hardware sits at the lower end. Smart locks, high-security deadbolts, or installations requiring door adjustments cost more because they take longer and require specialized knowledge.
The cost includes professional installation that prevents security gaps, ensures smooth operation, and eliminates the risk of DIY mistakes that leave your door vulnerable. You’re also paying for same-day service, OEM quality parts, and 140 years of expertise that gets the job done right the first time.
