Hear from Our Customers
You’re standing outside your front door. Keys are inside. Maybe you ran out to grab the mail, or maybe you just moved in and the old locks make you nervous. Either way, you need someone who can fix this without breaking your door, draining your wallet, or making you wait half the day.
That’s where we come in. We handle home lockouts, rekeying, new lock installation, deadbolt services, and everything in between. You get back inside fast, your locks work the way they should, and you’re not left wondering if someone else still has a key to your place.
We’ve been doing this in Delaware County since 1981. Our family’s been in locksmithing since the late 1800s. That means when you call McCausland Lock Service, you’re not getting someone who learned from YouTube last week—you’re getting generations of real skill.
McCausland Lock Service isn’t some national chain with a toll-free number and technicians who don’t know the area. We’re local to Delaware County, with a storefront right in Prospect Park. We’ve been serving Eddystone and the surrounding communities for decades.
Tom McCausland and his daughter Chrissy run the business now, carrying on a tradition that started generations ago. We’re licensed, we’re experienced, and we’re not here to take advantage of you when you’re in a bind. That’s why families in Eddystone keep our number handy.
Whether it’s a home lockout on a Tuesday morning or you just bought a house and need the locks rekeyed, we show up, do the work right, and charge you fairly. That’s it.
First, you call us and tell us what’s going on. Locked out? Need new locks installed? Want to rekey after moving in? We’ll give you a straight answer about what needs to happen and what it’ll cost—no surprises later.
Then we schedule a time that works for you, or if it’s an emergency lockout, we get someone out as fast as we can. Our technician shows up with the tools and parts needed to handle the job on-site. No running around town looking for supplies.
If you’re rekeying, we adjust the lock mechanism so your old keys won’t work anymore and you get a fresh set. If you need new locks installed—deadbolts, electronic locks, mailbox locks, whatever—we install them properly so they actually protect your home. If you’re locked out, we get you back inside without tearing up your door. Then we make sure everything works before we leave.
You’re done. Locks work. Keys in hand. One less thing to worry about.

We handle the full range of residential locksmith services. That includes emergency home lockouts, residential rekeying services, new lock installation, deadbolt services, lock repair, mailbox locks, mortise locks, electronic locks, and door knobs and levers. If it locks and it’s on your house, we can work on it.
Rekeying is one of the smartest moves you can make after buying a home in Eddystone. You don’t know who the previous owner gave keys to—contractors, neighbors, cleaning services, relatives. Rekeying changes the internal pins so those old keys are useless, and it costs way less than replacing every lock. It’s security without the sticker shock.
If your locks are worn out, damaged, or just not cutting it anymore, we’ll install new ones. Deadbolts are your main line of defense—they’re what keep doors from getting kicked in. We can also set you up with electronic locks if you want keyless entry, or help you create a master key system so one key works on multiple locks. Whatever makes your life easier and your home safer.
Eddystone’s a tight-knit community, and people here work hard for what they have. Your home should feel secure, and your locks should actually do their job. We make sure that happens.
Rekeying is almost always cheaper than replacing your locks entirely. The exact cost depends on how many locks you need rekeyed and what type they are, but you’re generally looking at a fraction of what new locks would run you.
When you rekey, we’re changing the internal pins inside the lock so it works with a new key. The hardware stays the same—we’re just making the old keys useless. That means less labor, less material, and a lower bill for you.
If you just moved into a home in Eddystone and you’re worried about who might have copies of your keys, rekeying is the smart play. You get peace of mind without emptying your wallet. Give us a call and we’ll give you a straight quote based on your specific situation—no hidden fees, no upselling you on stuff you don’t need.
First, don’t panic. It happens to everyone at some point. You stepped outside to grab the mail or talk to a neighbor, the door closed behind you, and now you’re stuck.
Call us. We’ll get someone out to you as quickly as we can. Our technician will get you back inside without damaging your door or lock—no need to break a window or kick anything in. We use the right tools and techniques to open the lock properly.
Once you’re back inside, we can also rekey your locks right then and there if you want to make sure this doesn’t happen again with a spare key hidden somewhere, or if you’ve been meaning to update your locks anyway. The point is, you’re not stuck outside for long, and we’re not going to charge you an arm and a leg just because you’re in a tough spot. That’s not how we do business.
Rekey them. Unless the locks are broken, outdated, or low-quality, rekeying is the way to go. It’s faster, cheaper, and gets you the same result—nobody with the old keys can get into your house anymore.
Here’s the thing people don’t think about: when you buy a home, you have no idea how many copies of those keys are floating around. The previous owner might have given keys to contractors, house sitters, dog walkers, or family members. Maybe some of those keys got copied. You just don’t know.
Rekeying solves that problem. We change the lock mechanism so all those old keys are worthless, and you get a fresh set that only you control. If your locks are in good shape, there’s no reason to rip them out and start over. Save your money and just rekey. If the locks are cheap or damaged, then yeah, we’ll recommend replacing them with something better. But most of the time, rekeying does the job.
Yes. Deadbolts are one of the most important things you can have on your exterior doors. A regular doorknob lock is easy to force open—deadbolts are what actually keep intruders out. If you don’t have one on every exterior door, you should.
We install all types of deadbolts, from standard single-cylinder models to high-security options that are harder to pick or drill through. We’ll make sure they’re installed correctly, with the right strike plates and reinforcement, so they actually do their job.
We also handle electronic locks if you want to go keyless. These let you unlock your door with a code, a smartphone app, or even a fingerprint, depending on the model. They’re convenient if you’re tired of carrying keys or if you want to give temporary access to someone without handing over a physical key. We’ll walk you through the options and install whatever makes sense for your home and your budget.
If your lock is sticking, hard to turn, or not latching properly, it might just need repair. Sometimes it’s a matter of cleaning out dirt and debris, lubricating the mechanism, or adjusting the alignment. That’s a quick fix.
But if the lock is visibly damaged—maybe the key broke off inside, the cylinder is worn out, or someone tried to force it open—then replacement is usually the better call. Trying to repair a lock that’s too far gone is just throwing money at a problem that’ll come back.
We’ll be straight with you about what needs to happen. If a repair will do the job, we’ll handle it and save you the cost of a new lock. If the lock is toast and needs to be replaced, we’ll tell you that too and get you set up with something solid. We’re not here to sell you new locks if your old ones are fine—we’re here to make sure your home is secure and your locks actually work.
Yes. We’re licensed, we’re insured, and we’ve been doing this for a long time. McCausland Lock Service has been serving Delaware County since 1981, and our family’s been in the locksmith trade since the late 1800s.
That matters because there are a lot of scammers out there—unlicensed operators who show up, damage your locks, and then charge you ridiculous fees. Some of them even sell your security information to criminals. It’s a real problem in the locksmith industry.
When you call us, you’re getting a legitimate, established business with a physical storefront in Prospect Park. We’re not some fly-by-night operation with a fake Google listing. We’re local, we’re accountable, and we’re not going anywhere. You can trust that the person showing up at your door knows what they’re doing and won’t take advantage of you.
