About this service
Standard commercial locks offer a baseline of security, but businesses facing higher risk — from valuable inventory to sensitive data to regulatory requirements — need locks that resist picking, drilling, bumping, and unauthorized key duplication. Alpha Locks and Safe installs high-security commercial locks throughout Westchester County using products from Medeco, Mul-T-Lock, ASSA, and other UL-listed manufacturers.
High-security locks differ from standard hardware in several important ways: they use restricted keyways that prevent unauthorized key copying, hardened components that resist physical attack, and tighter tolerances that make picking and bumping virtually impossible. Many also include patented key-control systems with serialized key blanks that can only be duplicated with proper authorization.
We assess each entry point in your facility and recommend the appropriate security level — not every door needs the highest-rated lock, and we help you balance protection with budget. Installation includes mounting, alignment, key cutting, and testing. We also provide documentation of key assignments and can set up key-control policies for your organization. Our high-security installations are done once and done right, with heavy-duty hardware built to last for years.

Frequently Asked Questions
What makes a lock 'high-security'?
High-security locks use hardened steel components, anti-pick pins, anti-drill plates, and patented restricted keyways that prevent unauthorized key duplication. Brands like Medeco and Mul-T-Lock meet ANSI Grade 1 standards.
Is a high-security lock worth the investment for my business?
Yes, especially for businesses storing valuable inventory, sensitive data, or cash. High-security locks resist picking, bumping, drilling, and forced entry far better than standard commercial locks.
Can high-security locks be integrated with a master key system?
Absolutely. We design master key systems using high-security cylinders with restricted keyways. This gives you the convenience of master keying with the added protection of controlled key distribution.
Do you install Medeco, Mul-T-Lock, and ASSA ABLOY locks?
Yes. We are authorized to install and service locks from all major high-security brands including Medeco, Mul-T-Lock, ASSA ABLOY, and Schlage Primus.
How much does high-security lock installation cost?
High-security lock installation starts at $789 per door. The total cost depends on the brand, lock type, and number of doors. We provide an upfront quote before beginning work.
