Question 1

What makes a lock 'high-security'?

Accepted Answer

High-security locks are certified to resist professional attack tools — picks, bump keys, and drills. They feature hardened steel inserts, security pins, and patented keyways. The key difference from standard locks: a professional cannot open them in seconds.

Question 2

What is key control and why does it matter?

Accepted Answer

Key control means duplicate keys can only be made by authorized locksmiths using registered keyways. This prevents tenants, ex-partners, or anyone else from copying your key without your knowledge — a critical feature for brownstone owners and landlords.

Question 3

Is Medeco better than Mul-T-Lock?

Accepted Answer

Both Medeco and Mul-T-Lock are the industry's two highest-rated lock brands. Medeco uses a unique rotating pin and angled key cut system. Mul-T-Lock uses a telescopic pin tumbler. Both achieve equivalent security — the choice often comes down to key style preference.

Question 4

How much more expensive is a high-security lock than a standard lock?

Accepted Answer

High-security locks cost $200–$500 installed compared to $125–$200 for standard locks. Given the security benefit and key control program, most Brooklyn homeowners and landlords consider it a worthwhile investment.

Question 5

Can you upgrade my existing lock to high-security without changing the door hardware?

Accepted Answer

Often yes — we can replace the cylinder in an existing mortise lock or deadbolt with a high-security Medeco or Mul-T-Lock cylinder, preserving your existing hardware while gaining premium protection.
