High-Security Key Systems for NH & ME Businesses
Eliminate unauthorized key duplication with pick-resistant, patented key systems designed by A&B Lock.
Advanced Key Control for Businesses That Can’t Compromise
When security is critical, traditional keys don’t cut it. High-security key systems from A&B Lock and Security give your business better protection with keys that are harder to duplicate, locks that resist tampering, and complete control over who has access.
We design and maintain restricted keyway systems for offices, municipalities, healthcare, retail, and industrial clients across New Hampshire and Southern Maine. Whether you need one high-security door or 50 keyed locations, we’ll recommend and install the system that fits your needs and budget.
