Your family stays safe, your property stays protected, and you sleep better knowing your locks actually work the way they should.
McCausland Lock Service has been solving lock problems in Linwood and Delaware County since the late 1800s. Tom McCausland and his daughter Chrissy run the largest locksmith operation in the Delaware Valley from our Prospect Park storefront.
You’re not just getting a locksmith when you call us – you’re getting a piece of Delaware County history. Four generations of expertise means we’ve seen every lock problem possible and know exactly how to fix it right the first time.
You call, we dispatch the closest mobile technician immediately. Most Linwood locations get 20-30 minute response times because we understand every minute counts when you’re locked out.
The technician arrives with a fully stocked mobile unit containing the tools and parts needed for your specific situation. We assess your lock, explain your options clearly, and get you back inside using non-destructive methods that won’t damage your property.
If it’s an emergency lockout, we handle that first. Then we can rekey your locks on-site if needed, cutting new keys for authorized personnel only. You get back to your day while knowing your security is actually improved.

We handle residential rekeying services, new lock installation, deadbolt services, lock repair, mailbox locks, mortise locks, electronic locks, and door knobs & levers. We’re authorized dealers for Kwikset, Medeco, and Schlage – the brands Linwood homeowners trust most.
Delaware County residents choose us because we use OEM parts that last longer, meaning you won’t be calling for the same problem next month. Our Prospect Park storefront lets you walk in for immediate key cutting, including those “hard to find” keys other places can’t handle.
From smart lock installation to traditional deadbolt services, we cover every security need without the runaround or surprise fees that frustrate busy homeowners.
Rekeying typically costs $50-100 per lock, which is significantly cheaper than full lock replacement at $200+ per lock. We provide upfront pricing so you know exactly what you’re paying before work begins.
The cost depends on your lock type and how many locks need rekeying. Most Linwood homeowners save hundreds by rekeying instead of replacing perfectly good locks. You get new keys that work, old keys stop working, and your existing hardware stays intact.
Rekey if your locks are in good condition and you like the current hardware. Replace if locks are worn out, damaged, or you want to upgrade to electronic locks or smart lock systems.
After moving into any new home, you don’t know who else has keys – previous owners, contractors, real estate agents, or neighbors. Rekeying ensures only you and your family have access. We can rekey most standard residential locks to work with one master key, reducing your keychain clutter while improving security.
Most Linwood locations get 20-30 minute response times for emergency lockouts. We operate the largest locksmith fleet in Delaware County, so there’s usually a technician nearby when you need help.
We understand that being locked out of your home or car disrupts your entire day. That’s why emergency calls get priority dispatch, and our mobile units carry the tools needed to get you back inside quickly without damaging your property.
Rekeying changes the internal pins so your existing lock works with new keys, while changing locks means replacing all the hardware completely. Rekeying costs much less and takes less time since your current lock hardware stays in place.
Choose rekeying when your locks work fine but you need new keys for security reasons. Choose full replacement when locks are broken, worn out, or you want to upgrade to better security features like smart locks or high-security deadbolts.
Yes, we service all residential lock types including deadbolts, door knobs, levers, mailbox locks, mortise locks, and electronic locks. We’re authorized dealers for major brands like Kwikset, Medeco, and Schlage.
Our 140+ years of experience means we’ve worked on every lock type you’ll find in Linwood homes, from vintage mortise locks in older houses to the latest smart lock technology. We stock OEM parts and can handle repairs, installations, and upgrades for any residential locking system.
Yes, we can create new keys even when you don’t have the original. This requires additional labor to pick or decode the lock first, but it’s often still cheaper than full lock replacement.
Our Prospect Park storefront has specialized equipment for cutting those “hard to find” keys that other places can’t duplicate. Whether it’s an old house key, specialty lock, or unusual key blank, our decades of experience and comprehensive key-cutting capabilities handle what others can’t.
