Frequently Asked Questions
Restricted keyways, tighter tolerances and hardened components resist copying, picking and bumping far better than standard locks.
No. Restricted keys require authorization and specialized blanks, so unauthorized copies cannot be made.
For sensitive homes and businesses, the added key control and attack resistance are well worth it.
