Residential Lock Repair and Maintenance

Locks wear out over time, leaving your home vulnerable. Our residential lock repair services in CT address issues like difficulty turning keys, loose deadbolts, or locks that stick. Instead of a full lock replacement, our experts can often restore functionality and extend the life of your existing locks.



New Lock Installation

If you’re moving into a new home or simply want to improve home security, new lock installation is one of the most effective solutions. From traditional knob locks to high-security deadbolts and electronic locks, we install a wide range of door hardware with precision, so you can trust your home is well protected.

Rekeying Services

Rekeying is a cost-effective alternative to a full lock change. Ideal for new homeowners or anyone who has misplaced a set of keys, a lock rekey allows your current lock hardware to work with a brand-new key. This service ensures only the people you choose have access to your home.


Key Duplication

Families often need extra keys for spouses, children, or trusted visitors. We provide accurate and reliable key duplication services, using high-quality key blanks to ensure each copy works smoothly. Our service covers standard house keys as well as specialty designs where applicable.


Smart Lock Upgrades

Modern homes benefit from the convenience of security solutions such as smart locks and keyless entry systems. As a top residential locksmith in CT, we help you upgrade to technology that offers remote access, smartphone integration, and improved access control. Smart locks bring added convenience without sacrificing security.


Security Hardware Installation

Locking mechanisms are just one part of a secure home. We also install high-security hardware, including deadbolts, reinforced strike plates, latch guards, and durable door hardware. These upgrades provide an extra layer of protection and peace of mind for your household.
