High-Security Hardware
Restricted keyways. Pick- and drill-resistant. Keys that can't be copied at a hardware store.
South Bronx Locksmith & Intercom Services installs pick- and drill-resistant, high-security door hardware with restricted keyways — including Medeco, Mul-T-Lock and ASSA — so keys can't be duplicated without your written authorization.
What this covers
High-security hardware uses patented, restricted key blanks that can't be duplicated at a hardware-store key kiosk — only through an authorized dealer with your signature on file.
The cylinders themselves are engineered to resist picking, bumping and drilling, which is why they're standard for multi-unit buildings, storefronts, and anyone who has ever had to worry about who has a copy of their key.
Signs you need this
- You manage a multi-unit building and want to control who can duplicate keys
- A previous tenant, contractor or employee may still have a copy of your key
- Your storefront has been targeted for break-in attempts
- You want documented, restricted key control for compliance or insurance
- You're upgrading from a standard pin-tumbler lock to something pick-resistant
Frequently asked questions
What brands do you install?
Medeco, Mul-T-Lock, and ASSA — all restricted-keyway systems with authorized-dealer key control.
Can someone copy my key at a regular hardware store?
No. Restricted keyways can only be cut by an authorized dealer, and only for people on your signed authorization list.
Does high-security hardware fit my existing door?
In most cases yes — these systems are built to standard door preps. We confirm fit before ordering hardware.
