High-Security Locks FAQ
Common questions about our service in New Haven, CT 06511
What makes a lock 'high-security'?
High-security locks resist picking, bumping, and drilling, and use restricted keyways so keys can't be copied without your authorization. Leading brands include Medeco, Mul-T-Lock, and ASSA Abloy.
Can high-security locks be picked?
They're extremely difficult to pick or bump due to their pin designs and sidebars, providing far greater resistance than standard locks.
Are restricted keys really uncopyable?
Restricted-keyway keys require authorized blanks and a signature on file to duplicate, so they can't be copied at a hardware store.
Do you install high-security locks for homes too?
Yes. We install high-security deadbolts for homes in New Haven, CT 06511 — a strong upgrade over standard hardware-store locks.
Is high-security lock installation available 24/7?
Yes. We install and service high-security locks at homes and businesses any time, day or night.
