You shouldn’t have to wrestle with your door knob after a long day. When your door lever sticks, your deadbolt won’t turn, or you’re standing outside in the cold because the lock decided to quit, that’s not just annoying—it’s a security risk.
Professional door knob installation fixes the problem completely. You get hardware that turns smoothly every single time, installed with the right measurements so your door actually latches properly. No gaps, no wiggling, no wondering if someone could just push their way in.
The difference between a DIY job and professional installation shows up in how long it lasts. When the backset measurement is off by even a quarter inch, your door knob will fail early. When the strike plate isn’t aligned correctly, you’ll be forcing that door closed within six months. We measure twice, install once, and you don’t think about your door hardware again for years.
You also get options you probably didn’t know existed. Smart locks that let you give your dog walker a temporary code. Deadbolts that actually meet insurance requirements. Door levers that work for everyone in your house, including anyone with arthritis or mobility issues.
We’ve been handling locksmith services in Delaware County since the late 1800s. Tom McCausland and his daughter Chrissy run what’s now the largest locksmith operation in the Delaware Valley, and we’re still doing the work the same way our great-grandfather did—show up when we say we will, fix it right, charge a fair price.
Tinicum Township families have trusted us for generations because we’re not a call center dispatching subcontractors. When you call, you’re talking to someone who actually knows locks. When we show up, it’s our reputation on the line, not some franchise owner three states away.
We’ve seen Tinicum change over 140 years, but the homes here still need the same thing—reliable security, honest service, and someone who won’t try to sell you something you don’t need. Your neighbors have been calling us for decades. That’s not marketing. That’s just what happens when you do good work long enough.
You call and describe what’s going on with your door hardware. We ask a few questions about your door type, the current hardware, and what you’re trying to accomplish—better security, easier access, updated look, whatever it is.
We schedule a time that actually works for you, and we show up in that window. Our mobile workshop has the specific tools and parts for your type of lock, so we’re not running to the hardware store mid-job.
When we arrive, we assess your door and frame to make sure the new hardware will work correctly. Sometimes the issue isn’t the knob at all—it’s how the door’s sitting in the frame. We’ll tell you that upfront, explain what it takes to fix it properly, and give you the exact cost before we touch anything.
The installation itself takes 20-30 minutes for a standard door knob replacement. We remove the old hardware without damaging your door, install the new lever or knob with precise measurements, and test it multiple times to make sure it latches smoothly and locks securely.
If you’re upgrading to a smart lock or adding a deadbolt, we handle the programming and show you how everything works. You’re not reading a manual later trying to figure out how to add user codes. We walk you through it right there.
Before we leave, we clean up completely and make sure you’re comfortable with how everything operates. You get manufacturer warranties on the parts, and you have our number if anything comes up.

Professional door knob installation means we handle the full scope—removal of old hardware, proper measurement and drilling if needed, installation of new components, and testing to ensure everything functions correctly. You’re not left with a half-finished job or a door that doesn’t close right.
We carry quality products from Kwikset, Schlage, and Medeco. These aren’t the builder-grade knobs that loosen up after a year. They’re manufacturer-backed hardware designed to last, and we install them according to spec so those warranties actually mean something.
In Tinicum, PA, we see a lot of older homes where the door frames have settled over time. That means the original hardware location might not work anymore, or you need shims to get proper alignment. We adjust for that during installation so your new door lever doesn’t bind or stick like the old one did.
Same-day service is standard for most residential locksmith work. If you need a door knob replaced, we’re typically there within a few hours, not next week. For Tinicum Township residents, that means you’re not leaving your house unsecured or dealing with a broken lock any longer than necessary.
We also handle rekeying during the same visit if you want all your locks on one key. That’s common for Tinicum homeowners who’ve lived in their house for years and accumulated different keys for different doors. One service call, everything works together, and you’re done.
Professional door knob installation typically runs $150-$250 per door depending on the hardware you choose and whether any adjustments are needed to your door or frame. That includes labor, the new knob or lever, and testing to make sure everything works correctly.
If you’re buying hardware separately and just need installation, labor alone is usually $75-$125 per door. But most homeowners find it’s worth having us supply the hardware because we know which products hold up and we can get manufacturer-approved parts that come with real warranties.
The price goes up if you’re installing smart locks or high-security deadbolts, usually $200-$350 depending on the system. But that includes programming, setup, and showing you how to use all the features. You’re not paying dealership prices, and you’re getting it done right the first time without the trial-and-error of a DIY install.
Yes, most exterior doors can accommodate smart lock installation without major modifications. The key is making sure your door thickness and backset measurements match the smart lock specifications, which we verify before installation.
Some smart locks replace your existing deadbolt, while others work with your current hardware. We’ll assess what you have now and recommend options that fit your door, your security needs, and your budget. If your door needs any prep work—like drilling for a larger cylinder or adjusting the strike plate—we handle that during installation.
The programming and setup is included. We connect the lock to your phone, set up user codes, and make sure you understand how to manage access remotely. Most Tinicum homeowners are surprised how straightforward smart locks are once someone shows them how it actually works instead of just handing them an instruction manual.
A door knob requires you to grip and turn, while a door lever operates with downward pressure. Levers are easier to use when your hands are full, and they’re significantly better for anyone with arthritis, limited hand strength, or mobility challenges.
Building codes for commercial properties require levers for accessibility reasons, but many Tinicum homeowners are switching to levers in their own homes because they’re just more practical. You can open a lever door with your elbow when you’re carrying groceries. You can’t do that with a knob.
Security-wise, there’s no meaningful difference if you’re using quality hardware. Both knobs and levers come in keyed entry, privacy, passage, and dummy configurations. The choice comes down to personal preference and who’s using the door. We install both, and we can show you options in each style that match your home’s look and your functional needs.
A straightforward door knob replacement takes 20-30 minutes once we’re on site. That’s removing the old hardware, installing the new knob or lever, and testing it to make sure it latches and locks properly.
If we’re installing a deadbolt in addition to the knob, add another 20 minutes. Smart lock installation takes about 45 minutes because of the programming and setup. If your door or frame needs adjustment—which happens sometimes in older Tinicum homes where things have settled—that might add 15-30 minutes depending on what’s required.
We’re not rushing through the job, but we’re also not dragging it out. We’ve done this thousands of times, we have the right tools in our mobile workshop, and we know exactly what needs to happen. You’re back to your day quickly, and your door works correctly.
If you’ve been in your Tinicum home for a while and you’re not sure who has keys—previous owners, old contractors, former neighbors who had a spare—rekeying makes sense. It’s cheap insurance that only the people you want coming in can actually get in.
Rekeying costs $20-$35 per lock when we’re already there doing installation work. We can rekey your new door knob to match your existing house key, or we can rekey everything to a new key so all your doors work on one key. Most homeowners choose the latter because it’s more convenient.
The process takes just a few minutes per lock. We remove the cylinder, replace the pins to match your new key, and reassemble everything. You get new keys on the spot, and you have complete control over who has access to your home. It’s one of those things that costs very little but gives you real peace of mind.
Yes, we handle emergency locksmith services throughout Tinicum Township and Delaware County. If your door knob breaks and you can’t secure your home, or if you’re locked out because the mechanism failed, we typically arrive within 20-30 minutes.
Emergency service costs more than scheduled work—usually $100-$150 service call fee plus the repair or replacement cost. But you’re not waiting until tomorrow, and you’re not leaving your house unsecured overnight. We carry common replacement parts in our mobile workshop, so most emergency repairs are completed on the first visit.
We use damage-free techniques to get you back inside. That means we’re not breaking windows or destroying your door frame. Professional locksmiths have tools and methods that preserve your property while solving the immediate problem. Then we can discuss whether you need a simple repair or if it makes more sense to replace the hardware entirely.
