You’re not just getting back inside your home or business. You’re getting peace of mind that comes from working with locksmiths who’ve been perfecting their craft for over 140 years.
Whether you need emergency lockout help, residential rekeying services, or new lock installation, we handle each job with the expertise that only comes from five generations of hands-on experience. No guesswork, no return visits to fix the same problem twice.
Your time matters, your security matters, and your investment in quality locksmith services should actually protect what’s important to you. That’s exactly what happens when you work with professionals who understand both the technical details and the urgency of your situation.
The McCausland family has been solving lock problems since the late 1800s. What started with Charles McCausland Senior learning the trade from his father has grown into the largest locksmith operation in the Delaware Valley.
Today, fourth-generation locksmith Tom McCausland and his daughter Chrissy continue that tradition of reliable service from our Prospect Park location, just minutes from Thornbury. When you call us, you’re getting more than a locksmith—you’re getting a piece of Delaware County history that’s built on actually solving problems.
We understand the Thornbury community because this isn’t just another service area on our map; it’s where our neighbors live and work, and we treat every job accordingly.
First, we listen to your specific situation and give you an accurate timeframe for arrival. No vague “sometime this afternoon” promises—you get a real window you can count on.
Our technician arrives with a fully stocked mobile unit containing the tools and parts needed for most jobs. We diagnose the problem, explain your options clearly, and give you upfront pricing before any work begins.
Then we solve it. Whether that’s getting you back into your locked home, rekeying your deadbolt services, installing new mortise locks, or repairing electronic locks, we handle it completely during that visit. You’re not waiting for parts orders or scheduling follow-up appointments unless it’s a complex commercial project that requires it.

Our locksmith services include residential rekeying services, new lock installation, home lock-out solutions, deadbolt services, lock repair, mailbox locks, mortise locks, electronic locks, and door knobs & lever installations. We also handle automotive lockouts and commercial security systems.
Thornbury’s mix of established homes and newer developments means we see everything from vintage mortise locks that need specialized attention to modern electronic locks requiring programming. We stock parts for major manufacturers including Kwikset, Medeco, and Schlage, so most jobs get completed on the spot.
The advantage of working with Delaware County’s largest locksmith company is simple: we have the experience, equipment, and inventory to handle whatever lock challenge you’re facing. From simple key cutting to complex master key systems, one call gets it done right.
Most Thornbury emergency lockouts get resolved within 20-30 minutes of our arrival, and we typically reach you within 30-45 minutes of your call during normal business hours. Emergency response times can vary based on your exact location within Thornbury and current call volume.
We maintain mobile units strategically positioned throughout Delaware County, with our main facility in nearby Prospect Park. This means you’re not waiting hours for someone to drive across the region. When you’re locked out of your home or business, every minute counts, and our response times reflect that understanding.
Yes, residential rekeying services are one of our most common requests in Thornbury. We can rekey your existing locks so old keys no longer work while providing you with new keys that operate all your rekeyed locks.
This is particularly valuable when you’ve moved into a new home, lost keys, or need to revoke access for former tenants or employees. Rekeying costs significantly less than replacing entire lock sets, and we can typically rekey multiple locks to work with a single key for your convenience. Most residential rekeying jobs are completed during the same visit.
We install all types of residential and commercial locks including deadbolt services, mortise locks, electronic locks, door knobs & lever sets, and mailbox locks. Our technicians are experienced with both standard installations and more complex situations like reinforcing door frames or installing locks in unusual door configurations.
For Thornbury homes, we frequently install high-security deadbolts, smart locks that integrate with home automation systems, and keyless entry systems. We carry quality products from trusted manufacturers and can recommend the best options based on your specific security needs and budget. All installations include proper alignment and testing to ensure smooth operation.
Absolutely. Electronic locks and smart lock systems are becoming increasingly common in Thornbury homes, and we have extensive experience repairing and servicing these advanced systems. This includes troubleshooting connectivity issues, replacing batteries, reprogramming access codes, and updating firmware when needed.
We work with most major smart lock brands and can often resolve electronic lock problems without requiring complete replacement. Our technicians carry diagnostic tools specifically designed for electronic lock systems, and we stay current with the latest technology updates. Whether your smart lock has stopped responding to your phone app or needs integration with a new home security system, we can handle it.
Locksmith service costs in Thornbury vary based on the specific work needed, but we provide upfront pricing before beginning any job. Simple services like key cutting or basic lockout assistance typically cost less than complex installations or emergency after-hours calls.
Our pricing is consistently lower than what you’d pay at car dealerships for automotive work, and we’re competitive with other professional locksmith services in Delaware County. We don’t charge extra for using credit cards, and we accept multiple payment methods for your convenience. The key difference is that our pricing includes the expertise of five generations of locksmithing experience, quality OEM parts, and service that’s done right the first time.
Yes, we serve all of Delaware County and surrounding areas including Media, Upper Darby, Chester, Springfield, and parts of Philadelphia, Chester, Montgomery, and Bucks counties. Our central Prospect Park location allows us to efficiently serve the entire region.
