Key Duplication
Our ALOA-certified technicians create precision key duplicates using manufacturer specifications and high-quality blanks. We service residential, commercial, and specialty applications including office furniture and elevator locks. Routine equipment maintenance ensures lasting functionality that exceeds generic key quality.

Secure your property by reconfiguring lock cylinders to work with new keys. We handle Schlage, Kwikset, Yale, and other major brands, ensuring only authorized keys operate your locks. This cost-effective solution eliminates unauthorized access while maintaining existing hardware.

Custom hierarchical key systems allow tiered access for different personnel. Our experts design secure configurations balancing convenience with controlled access, preventing accidental security breaches while maintaining operational efficiency for commercial properties.
Hardware Installation
Professional installation of deadbolts, electric strikes, exit devices, and commercial-grade locks. Our certified technicians ensure proper alignment and code compliance, enhancing security while maintaining aesthetic appeal through precise craftsmanship and quality materials.

Semi-annual 10-step door inspections identify potential issues before failures occur. Our maintenance plans include lubrication, alignment checks, and component testing for commercial clients, extending hardware lifespan and preventing security vulnerabilities through proactive care.
