High-Security Lock Installation
Pick-resistant cylinders and keys that can't be copied without your permission.
When a Standard Lock Isn't Enough

Standard locks can be picked, bumped, and their keys copied at almost any hardware store. High-security locks add layers of protection: complex pin designs that resist picking and bumping, hardened parts that resist drilling, and, most important for many businesses, restricted keyways.
What Restricted Keys Mean
A restricted key uses a controlled key blank that ordinary key shops can't buy. Duplicates can only be made through an authorized locksmith, and only with the owner's approval. You always know how many keys exist.
