High-security hardware is about key control: restricted keyways, hardened components, and copies cut only for the cardholder on record.
What high-security means in practice
These systems differ from stock hardware by mechanism, not by promise. Restricted keyways mean blanks are not sold on the open market. Copies require the authorization card or signature on file. Cylinders use hardened components and tighter machining tolerances than builder-grade locks.
Who asks for this
- Owners who want to know exactly how many keys exist
- Townhouse and brownstone owners consolidating several doors under one controlled key
- Landlords and supers running master key systems with accountability
- Shops and offices where staff turnover means key turnover
How a system gets set up
We look at your doors, existing hardware, and who needs which access. Then the cylinders are fitted, the authorization record is established, and future copies run through that record at the shop on 1st Ave.
Common questions
Can one restricted key open several doors?
Yes, where the cylinders are keyed together under the system. That is a common setup for a townhouse front door, garden door, and cellar gate.
What happens if a restricted key is lost?
The affected cylinders are rekeyed within the system and fresh keys are issued against the record, so the missing key no longer turns them.
