You’re not stuck outside your Marple home or business for long when you call McCausland Lock Service. We get you back inside fast, then make sure it doesn’t happen again with proper lock maintenance and security upgrades.
Your locks work reliably after we service them because we use OEM parts from manufacturers like Schlage, Kwikset, and Medeco. No cheap replacements that break down in a few months, leaving you with the same problem all over again.
Whether it’s a simple rekey after moving into your new Marple home or installing smart locks that work with your phone, you get solutions that actually solve your security concerns for the long term.
Our family has been solving lock problems since the late 1800s, and we’re still here because we do the work right the first time. Tom McCausland and his daughter Chrissy now run the largest locksmith operation in the Delaware Valley from our Prospect Park storefront.
We’ve handled everything from simple house key copies to complex commercial security installations for Marple residents and businesses. Our mobile fleet serves a fifteen-mile radius, so you’re never too far from help when you need it most.
You’re getting more than a locksmith when you call us—you’re getting a piece of Delaware County history and the kind of service that keeps families coming back for generations.
When you call McCausland Lock Service, we dispatch our closest mobile technician to your Marple location within 20-30 minutes. Our vans are fully stocked with the tools and parts needed to handle your specific lock problem on the spot.
We assess your situation first—whether it’s a lockout, broken key, or security upgrade need. Then we use non-destructive entry methods that get you back inside without damaging your property or creating expensive additional problems.
Once you’re back inside, we can immediately address any security concerns. If you’ve lost keys or had a break-in, we rekey your locks on-site so old keys stop working instantly while cutting new keys for authorized people only. You get back to your day quickly while eliminating ongoing security risks.

Marple homeowners get comprehensive locksmith services that cover every entry point to your property. We handle residential rekeying when you move in, deadbolt installation for enhanced security, and smart lock setup that works with your existing home automation systems.
Your mailbox locks, door knobs, levers, and electronic locks all get professional installation and maintenance. We work with the lock brands you trust—Schlage, Kwikset, Medeco—and carry mortise locks for older Marple homes that need specialized hardware.
Delaware County’s housing market means people are constantly moving, renovating, and upgrading their security. We see increased demand for keyless entry systems and biometric locks as Marple residents want convenience without sacrificing protection. Our technicians stay current on the latest smart lock technology while maintaining expertise with traditional mechanical systems.
We typically respond to Marple lockouts within 20-30 minutes during regular business hours and emergency calls. Our mobile technicians are strategically positioned throughout Delaware County, so you’re never waiting long when you’re locked out.
Our response time depends on your exact location in Marple and current call volume, but we prioritize emergency lockouts because we understand every minute counts. When you’re locked out of your home or car, especially in bad weather, you need help fast.
We dispatch immediately when you call and keep you updated on our arrival time. Our technicians carry everything needed to get you back inside without damaging your locks or property.
Yes, we install, repair, and maintain smart locks and electronic entry systems throughout Marple. Our technicians are trained on the latest biometric locks, keyless entry systems, and app-controlled smart locks from major manufacturers.
We handle everything from basic smart deadbolts to complex commercial access control systems with multiple entry points. This includes troubleshooting connectivity issues, updating firmware, and integrating new smart locks with your existing home automation setup.
Smart lock technology is advancing rapidly, and we stay current on cybersecurity best practices to ensure your electronic locks are properly secured against hacking attempts. We also educate customers on proper maintenance to keep these systems functioning reliably.
Rekeying changes the internal mechanism of your existing lock so old keys no longer work, while replacement involves installing completely new lock hardware. Rekeying is usually more cost-effective when your locks are in good condition but you need new keys.
We recommend rekeying when you move into a new Marple home, after a break-in, or when you need to revoke access for former tenants or employees. It’s faster and less expensive than full replacement, and we can do it on-site in most cases.
Lock replacement makes sense when your hardware is worn out, damaged, or you want to upgrade to smart locks or higher security grades. We’ll assess your specific situation and recommend the most practical and cost-effective solution for your security needs.
Yes, we specialize in cutting keys for older, rare, and unusual lock systems that other locksmiths often can’t handle. Our Prospect Park storefront has key-cutting equipment for vintage locks, specialty automotive keys, and even some safe keys.
Many older homes in Marple have mortise locks, antique door hardware, or discontinued lock brands that require specialized knowledge and tools. We’ve been in business for over 140 years, so we’ve seen just about every type of lock system and maintain the tools to work on them.
If we can’t cut your key on-site, we have relationships with specialty suppliers and can often source or create custom keys for even the most challenging lock systems. We love the challenge of keys that other locksmiths turn away.
Yes, we provide 24-hour emergency locksmith services for urgent situations throughout Marple and Delaware County. This includes lockouts, break-in repairs, and security emergencies that can’t wait until regular business hours.
Emergency calls do include additional fees for after-hours service, but we’ll always quote you the total cost upfront before starting any work. We understand that lock emergencies don’t happen on a convenient schedule, especially during holidays or bad weather.
Our emergency technicians carry the same tools and parts as our regular service calls, so we can complete most jobs immediately rather than having to return the next day. We prioritize getting you secure and back inside as quickly as possible.
We recommend Schlage, Kwikset, and Medeco locks for most Marple residential applications because they offer reliable performance, good warranty coverage, and parts availability. As authorized dealers for these brands, we can provide genuine replacement parts and warranty service.
The best lock brand for your home depends on your security needs, budget, and whether you want smart features. Schlage offers excellent smart lock options that integrate well with home automation systems, while Medeco provides high-security mechanical locks for maximum protection.
We stock these brands in our Prospect Park location and on our mobile service vehicles, so we can install or repair them immediately. We’ll assess your specific doors, security requirements, and preferences to recommend the most appropriate lock system for your Marple home.
