Hear from Our Customers
Your front door works the way it should. No more wiggling the handle for two minutes every time you come home with groceries. No more wondering if the lock actually caught when you left for work.
You get hardware that fits your home’s style and your security needs. We’re talking about solid installation that doesn’t strip screws, crack trim, or leave gaps around the plate. The kind that lasts years, not months.
And you’re not stuck waiting around for a three-hour service window. Most door knob installations in Aston take us under an hour. We show up when we say we will, explain what needs to happen, and get it done without turning your entryway into a construction zone.
The difference is simple: you stop thinking about your door hardware because it just works.
McCausland Lock Service has been handling locksmith services since the late 1800s. Fourth-generation locksmith Tom McCausland and his daughter Chrissy run the largest locksmith operation in the Delaware Valley from our Prospect Park storefront, just minutes from Aston.
We’re not a call center dispatching whoever’s available. Our mobile technicians carry fully stocked workshops and arrive within 20-30 minutes for most calls across Aston, PA. We use OEM parts from Kwikset, Schlage, and Medeco because we’ve seen what happens when you cut corners on hardware.
Aston homeowners deal with the same issues we see across Delaware County: old Colonial-revival homes with original hardware that’s finally giving out, newer builds where builder-grade knobs didn’t hold up, and security upgrades after moving into a home where you’re not sure who still has keys. We handle all of it.
First, we look at what you’re working with. Is this a simple swap on a standard bore, or are we dealing with misaligned holes, damaged frames, or non-standard sizing? We measure the backset, check the door thickness, and make sure the new hardware will actually fit before we touch anything.
Then we remove the old knob or lever without damaging your door or trim. If the strike plate is worn or the holes are stripped, we fix that too. No point installing new hardware on a frame that won’t hold it properly.
We install the new door knob or lever, making sure everything aligns correctly. The latch catches cleanly. The knob turns smoothly. The lock engages without forcing it. We test it multiple times because that’s how you catch problems before they become your problems.
If you’re upgrading to keyed entry, we can rekey it to match your existing house key so you’re not carrying extra keys. If you need multiple doors done, we handle them all in one visit. You’re not scheduling us three different times for three different rooms.

You get the labor, the expertise, and the guarantee that it’s installed correctly. We bring the tools and hardware needed to handle standard installations and the unexpected issues that come up in older Aston homes.
Most residential door knob installations run between $95-$155 depending on the hardware type. Passage knobs for hallways and closets are on the lower end. Keyed entry locks and privacy locks for bedrooms and bathrooms cost more because there’s more to install and adjust.
If you’re supplying your own hardware, we’ll install it. If you need help choosing what works for your door and your budget, we stock quality options at our Prospect Park location. You can see Emtek displays and compare finishes in person instead of guessing based on online photos.
Aston’s housing stock runs the gamut from $158,000 townhouses to $700,000 single-family homes with large yards. That means we see everything from basic builder-grade replacements to high-end lever installations that need to match existing finishes throughout the home. We’ve handled both, and everything in between, for over a century across Delaware County.
Most standard door knob installations take 30-45 minutes per door. That’s assuming the existing bore holes are standard size and the door frame is in decent shape.
If we’re dealing with stripped screw holes, misaligned latches, or non-standard boring, it takes longer. Same goes if you’re upgrading from a passage knob to a keyed entry lock and we need to drill additional holes or modify the door edge. We’ll tell you upfront if we spot anything that’ll add time.
For multiple doors in one visit, figure about 30 minutes per door after the first one since we’re already set up. We’re not rushing through installations to get to the next call. We’re making sure each one works correctly before we move on.
Yes, as long as the backset and bore holes match standard sizing. Most modern doors use a 2-1/8″ bore hole and either a 2-3/8″ or 2-3/4″ backset, which means swapping a knob for a lever is straightforward.
Older homes in Aston sometimes have non-standard measurements or vintage hardware with different hole patterns. If that’s the case, we can either find compatible hardware or modify the door to accept standard sizing. Modifying costs more and takes longer, but it’s doable.
Levers are easier to operate than knobs, especially if you’re carrying things or dealing with arthritis. They’re also required by ADA standards for accessibility. We install a lot of them in Aston homes where homeowners are aging in place and want hardware that’s easier to use.
Yes, and we do it during the same visit. If you’re installing new keyed entry locks, we can rekey them to work with whatever house key you’re already using. You don’t need a separate key for the new hardware.
This matters most when you’re replacing multiple exterior doors or adding keyed locks to doors that didn’t have them before. Nobody wants to carry four different keys for four different doors on the same house.
Rekeying adds a few minutes to the installation but saves you the hassle of managing multiple keys or getting copies made. We carry blank keys and pinning kits in our mobile units, so there’s no delay or second trip needed. It’s just part of the service.
We fix it before installing the new hardware. Stripped screw holes get filled and re-drilled, or we use longer screws that bite into solid wood. Damaged strike plates get replaced. If the door edge is chewed up from a poorly installed latch, we clean it up and make sure the new latch sits flush.
Installing new hardware on a damaged frame is like putting new tires on a bent wheel. It might work for a week, but it’s going to fail. We’ve seen too many DIY installations where the knob looks fine but the door doesn’t latch properly because nobody addressed the underlying damage.
Most frame repairs add 15-30 minutes to the job and don’t require special parts. We’re talking about basic carpentry and locksmith work that should’ve been done right the first time. We handle it so your new door knob actually lasts.
Standard passage knobs for interior doors typically run $95-$135 installed. Keyed entry locks and privacy locks for bedrooms and bathrooms are usually $110-$155 installed. That’s labor and basic installation on a standard door with no complications.
If you need rekeying, frame repairs, or non-standard modifications, the price goes up. We’ll tell you exactly what it costs before we start work. No surprises, no “we found additional issues” upcharges after we’re halfway done.
Hardware cost is separate if you’re buying from us, but we’re not marking it up 200% like some companies do. You can also supply your own hardware and we’ll install it. Either way, you know what you’re paying before we touch your door.
Yes, most days we can get to you same-day if you call in the morning. Our mobile fleet covers Aston and the surrounding Delaware County area, and we dispatch the closest available technician to your location.
Emergency lockouts get priority, so if we’re slammed with people locked out of their homes or cars, non-emergency installations might get pushed to the next available slot. But for standard door knob replacement and installation work, same-day service is typical.
We’re not making you wait a week for a simple installation. You call, we give you a realistic timeframe, and we show up when we say we will. If something changes and we’re running late, we’ll let you know. That’s how this should work.
