Question 1

What makes a lock 'high security'?

Accepted Answer

High security locks meet ANSI/BHMA Grade 1 standards and carry additional certifications for pick resistance, drill resistance, and key control. Brands like Medeco, Mul-T-Lock, and ABLOY use patented keyways and sidebars that prevent picking, and restricted blanks that can't be duplicated at a hardware store.

Question 2

How much do high security locks cost in Brooklyn?

Accepted Answer

High security lock installation in Brooklyn starts at $249, which includes a Mul-T-Lock or Medeco cylinder installed in your existing hardware. A complete high security deadbolt or mortise set runs $350–$550 installed, depending on configuration. The investment is typically worth it for ground-floor units, building entry doors, and commercial spaces.

Question 3

Are Medeco and Mul-T-Lock keys harder to duplicate?

Accepted Answer

Yes — significantly. Both use patented, restricted keyways. Keys can only be duplicated by an authorized dealer (like us) with proof of ownership. We keep key records on file so you can request additional keys at any time. This is a major security advantage over standard keys.

Question 4

Can I upgrade just the cylinder to high security without replacing the whole lock?

Accepted Answer

In most cases yes — we can replace the cylinder in your existing deadbolt or mortise lock with a Medeco or Mul-T-Lock cylinder. This gives you high security key control without the cost of full hardware replacement.
