Why Using Sargent Locks
Sargent is a trusted name in lock hardware — known for sturdy construction, reliable mechanics, and consistent performance even under heavy daily use. For properties in Richardson — from homes and rental units to offices, schools, and multi-unit buildings — choosing Sargent for a lock change offers long-term value. Their locks are built to withstand frequent entry, rough handling, and years of wear, which makes them a solid choice for both residential and commercial applications.
One of the strongest advantages of Sargent locks is durability. Their deadbolts, cylindrical sets, and mortise systems are engineered for heavy traffic doors, ensuring that bolts, latch bolts, and mechanisms remain stable over time. This reduces maintenance requirements and lowers the risk of premature failure, which can be a problem with lower-grade residential locks.
Another benefit is flexibility. Sargent offers a wide variety of lock types — standard deadbolts, cylindrical and mortise sets, heavy-duty commercial locksets — so we can match the right hardware to your door type, traffic level, and security needs. Whether you're securing a home, a rental unit, or a commercial facility, Sargent gives options that balance security, durability, and usability.
The downside is cost. Sargent hardware typically costs more than basic residential locksets. Installation can also be more involved, especially for commercial-grade mortise or cylindrical systems. But for doors that face frequent use, heavy traffic, or need reliable security over many years, the durability and quality often justify the investment.
Sargent Lock Rekey
Sargent locks can often be rekeyed instead of replaced — a practical option if you just need to change access without upgrading hardware. During a Sargent Lock Change in Richardson, our locksmith can re-pin existing cylinders (if possible) or replace the core to render old keys useless while keeping the existing lock body intact. This is frequently chosen after move-outs, tenant changes, or staff turnover.
Because Sargent locks are built with commercial-grade precision, rekeying requires careful handling and sometimes specialized tools. Depending on the lock model, rekeying may take a bit longer and cost more than re-pinning a standard residential lock. However, it often remains a cost-effective and efficient solution when the lock hardware is still in good condition and you want to maintain consistent security without disruption.
Smart / Access-Control Locks
Though Sargent is best known for mechanical locksets, many property owners in Richardson ask us to combine Sargent hardware with modern access-control or smart lock modules. These upgrades allow keypad, card, or electronic access while retaining the heavy-duty reliability of Sargent’s mechanical components.
We can install electronic strike plates, keypad-equipped locksets, or retrofit smart lock modules onto existing Sargent doors, allowing you to control access via codes or cards rather than traditional keys. This approach is popular for rental buildings, shared offices, or multi-tenant properties where flexible, controlled access matters more than traditional keys.
During an appointment, we ensure door compatibility, install the electronics properly, program user codes or cards, and test both mechanical and electronic functions — ensuring secure, reliable operation before we leave. This gives you the convenience of modern access control with the strength of Sargent hardware behind it.
Do It Yourself vs Professional Locksmith
Because Sargent hardware is often heavier-duty and more complex than basic residential locks, DIY installation or rekeying can lead to problems. Issues like misaligned strike plates, improper bolt throw, or poor key control can reduce security and cause operational problems over time. Without the right tools and precision, the investment in Sargent locks may lose value.
Professional locksmith service ensures correct installation and adjustment. Our trained technicians handle door alignment, hardware fit, bolt seating, and any reinforcement needed — ensuring your Sargent lock performs as intended. For commercial-grade locks and high-traffic doors, professional installation dramatically improves long-term reliability and reduces risk of failures.
Additionally, we often provide warranty on parts and labor. If issues arise after installation — from key problems to mechanical wear — you have a trained locksmith to call. DIY solutions rarely offer that safety net, which is crucial when dealing with heavy-duty locks and frequent use.
