We focus exclusively on non-destructive entry methods that preserve your investment in your home. Damaging your property during an emergency would just create more costly headaches for you, which defeats the purpose of calling a professional locksmith.
If a lock is damaged beyond repair or if you’re dealing with a security breach situation, we’ll explain your options clearly before proceeding. In most cases, we can repair or replace the lock immediately using genuine manufacturer parts, so you’re not left with a compromised entry point.
Absolutely, and this is one of the smartest security moves new homeowners make. Rekeying means changing the internal mechanism so your old keys no longer work, while new keys are cut specifically for your locks. This is much more cost-effective than replacing all the hardware.
We can rekey most standard residential locks on-site during a single service call. This includes deadbolts, doorknob locks, and even some electronic systems. The process typically takes just a few minutes per lock, and you’ll have new keys that work across your entire home.
For Swarthmore homes with existing high-quality lock hardware, rekeying preserves your investment while giving you complete control over who has access. We can also set up master key systems if you want different access levels for family members, housekeepers, or other trusted individuals.
Our automotive locksmith services typically cost 40-60% less than dealership pricing while maintaining the same quality standards. Dealerships have high overhead costs and often subcontract locksmith work anyway, adding markup at each step.
We come directly to your location with factory-authorized equipment and genuine OEM parts. Most automotive jobs are completed while you wait, including key cutting, transponder programming, and ignition repairs. No appointment scheduling, no towing costs, no dealership waiting rooms.
For example, a standard car key replacement that might cost $200-300 at a dealership typically runs $80-150 through our mobile service. You get the same quality key and programming, but without the dealership markup and inconvenience of arranging transportation to their location.
Yes, we specialize in high-security installations for Swarthmore’s valuable properties. We’re authorized dealers for premium brands like Medeco, Schlage, and other manufacturers that produce locks specifically designed to resist picking, drilling, and other bypass techniques.
High-security locks use patented key designs that can’t be duplicated at hardware stores, giving you complete control over who can make copies. We also install electronic systems, smart locks, and integrated security solutions that work with modern home automation systems.
Our consultation process includes a security assessment of your property to identify vulnerable points and recommend appropriate upgrades. We consider factors like your home’s architecture, neighborhood characteristics, and your family’s lifestyle to design a security system that provides real protection without unnecessary complexity.

We can create different access levels for employees, management, and service personnel while maintaining detailed records of who enters which areas and when.
We also handle emergency commercial lockouts and security upgrades when employees are terminated or keys are lost. Our technicians can rekey entire systems on-site, reprogram electronic access controls, and cut new keys for authorized personnel—all during a single service call that minimizes disruption to your business operations.
