Hear from Our Customers
You’re not spending your Saturday watching YouTube videos trying to figure out which way the latch goes. You’re not making a second trip to the hardware store because the first knob didn’t fit your door prep.
When we install or replace your door knob, it works smoothly from day one. The latch catches every time. The lock turns without fighting you. And if you’re upgrading to a smart lock or keyless entry, it’s programmed and tested before we leave.
Most residential locksmith jobs in Radnor take us under an hour. You call, we show up with the right tools and the right parts, and your door hardware works the way it should. That’s it.
The McCausland family has been in locksmithing for over 140 years. Fourth-generation locksmith Tom McCausland and his daughter Chrissy run the largest locksmith operation in the Delaware Valley today.
We’re not a van with a magnetic sign. We have a storefront in Prospect Park where you can walk in, get keys cut, and see the hardware we install. We’ve been serving Radnor and Delaware County for over 59 years because we show up when we say we will and we don’t damage your door getting the job done.
Every technician carries OEM parts from Kwikset, Schlage, and Medeco. We’re members of the American Locksmith Association of Pennsylvania, and we’re background-checked and licensed. You’re letting us into your home, so that matters.
You tell us what’s going on. Maybe your knob is loose and won’t tighten. Maybe you’re replacing old brass hardware that doesn’t match your renovated home. Maybe you just moved into a Radnor property and want all the locks rekeyed and updated.
We ask a few questions about your door type, the current hardware, and what you’re looking for. If you already bought a knob, we’ll install it. If you haven’t, we bring options with us or you can swing by our Prospect Park shop to see what’s in stock.
We arrive within 20 to 30 minutes for most calls in Radnor. We remove the old hardware, prep the door if needed, install the new knob or lever, and test it multiple times. If it’s a deadbolt or smart lock, we make sure it’s aligned, programmed, and functioning before we pack up.
You’re not left with a half-installed door knob and a YouTube tutorial. The job’s done right, and you’ve got our number if anything comes up later.

We handle the full scope of door knob services. That means installation, replacement, repair, and rekeying. If your lever is sticking or your latch isn’t catching, we fix it. If you’re upgrading to electronic locks or smart deadbolts, we install and program them.
Radnor homes tend to be higher-end, and a lot of homeowners here care about matching finishes and maintaining curb appeal. We get that. We work with premium brands and we’re careful with your doors and trim. No scratches, no forced fittings, no “good enough” installs.
If you’re a new homeowner in Radnor, we also rekey your existing locks so old keys don’t work anymore. You can keep your current hardware and still get the security of a fresh start. Most people don’t realize that’s an option until we mention it.
We also handle mailbox locks, cabinet locks, and any other residential locksmith work you need done while we’re there. One call, one visit, everything handled.
Most door knob installation jobs run between $150 and $250 depending on the hardware and how your door is prepped. If you’re installing a basic passage knob on a standard door with existing holes, you’re on the lower end. If we’re drilling new holes, installing a smart lock, or working with a thicker or non-standard door, it costs more.
We don’t charge extra for showing up in Radnor. Our service area covers all of Delaware County and parts of Chester, Montgomery, Bucks, and Philadelphia counties. If you already have the hardware, let us know when you call and we’ll give you a tighter estimate.
The price includes installation, testing, and cleanup. We use OEM parts so the repair or install lasts. You’re not calling us back in three months because a cheap part failed.
Yes. We install and program electronic locks, smart deadbolts, and keyless entry systems from all the major brands. That includes locks you unlock with a code, a phone app, or biometrics.
A lot of Radnor homeowners are upgrading to smart locks because they want to let in a dog walker, housekeeper, or contractor without handing out physical keys. You can set temporary codes, track who comes and goes, and lock or unlock your door remotely.
We make sure the lock is compatible with your door, that it’s installed correctly, and that it’s synced to your phone or home system before we leave. If the battery dies or the app isn’t connecting, we walk you through it. You’re not stuck reading a manual in broken English trying to troubleshoot on your own.
Call us. We typically arrive within 20 to 30 minutes for emergency lockouts in Radnor and the surrounding Delaware County area. We get you back inside without breaking your door, your frame, or your windows.
No broken glass to replace. No splintered wood to repair. We have the tools and the training to open your door the right way, and we’ve been doing this for over a century as a family business.
Once you’re back inside, we can rekey your locks, replace your door knob, or install a keyless entry system so you don’t get locked out again. A lot of people don’t think about that until they’re standing outside at 10 PM, but it’s worth considering once you’re back in.
We rekey locks all the time, especially for new homeowners in Radnor. Rekeying means we change the pins inside your existing lock so the old keys don’t work anymore. You get new keys, but you keep your current door knobs and deadbolts.
It’s faster and cheaper than replacing all your hardware, and it makes sense if your locks are still in good shape. If your door knob is loose, sticking, or outdated, then replacement makes more sense.
We’ll tell you honestly which option fits your situation. If rekeying works, we’ll do that. If your hardware is worn out or you just want an upgrade, we’ll swap it out. Either way, you’re not wondering if someone from three owners ago still has a key that works.
Most installations take 30 minutes to an hour per door. If your door already has the right holes and we’re swapping out a standard knob or lever, it’s quick. If we’re installing a new lock on a door that’s never had one, or if we’re fitting a smart lock that needs programming, it takes a bit longer.
We don’t rush and we don’t leave a mess. We test the lock multiple times, make sure the latch is aligned, and clean up any debris before we go. You’re not left with a door that sort of works or a knob that catches every third time you turn it.
If you’re having multiple doors done, we can usually handle everything in one visit. Just let us know what you need when you call and we’ll block out enough time to get it all done right.
We install Kwikset, Schlage, Medeco, and most other major brands. Those are the manufacturers we carry in our shop and stock on our trucks, and they’re the ones we recommend because they last.
If you already bought a door knob or lever from a hardware store, we’ll install it. If you haven’t picked one out yet, we can show you options at our Prospect Park storefront or bring a few choices with us when we come out.
Radnor homeowners usually care about finishes and style, so we make sure whatever you choose matches your other hardware and fits your door correctly. We’re not going to force a knob onto a door it wasn’t designed for just to get the job done. If it doesn’t fit right, we’ll tell you before we start.
