Why high-security
What a standard lock can’t give you.
Pick & bump resistant
Patented pin systems defeat the tools that open ordinary cylinders in seconds.
Drill resistant
Hardened steel inserts stop drill attacks cold.
Key control
Keys can only be duplicated with your registration card — no hardware-store copies.
Insurance benefits
Many carriers discount premiums for certified high-security hardware. Ask yours.

Who needs this
Three doors we upgrade most.
Some doors don't need replacing — they need the right cylinder behind them. Whether you own a brownstone, run a small business, or manage a whole building, the right high-security core puts you back in charge of every key.
The brownstone owner
A street-facing door, original hardware, and a key that’s been copied who-knows-how-many times. One cylinder swap fixes all three.
The small business
Staff turnover means lost key control. Registered keys mean an ex-employee’s copy is just a souvenir.
The building manager
Master-key systems with high-security cores — one key for you, controlled access for everyone else.

High-security FAQ
Before you decide
Will a high-security cylinder fit my existing lock?
Usually yes. Mul-T-Lock and Medeco make cylinders for most common mortise and rim hardware, so your visible door furniture stays the same.
What stops someone copying my key?
Patented keyways and a registration card. Blanks aren’t sold to hardware stores, and duplication requires your card — by design.
How long does an install take?
Typically 1–2 hours per door, including fitting, testing, and key registration.
Is it worth it for a rental apartment?
Often yes, with landlord approval. The cylinder moves with you when you leave — it’s an asset, not a fixture.
