High-security cylinders
Medeco, Mul-T-Lock and Abloy — locks whose keys cannot be copied at a hardware store.
The value of a high-security cylinder is key control: blanks are restricted, so a tenant, a cleaner, or a contractor cannot quietly walk out with a duplicate. That matters most on multi-family entries and any door a lot of people have touched.

Straight answers
What makes a cylinder high-security?
Restricted key blanks (copies need your documented authorization), plus pick, bump and drill resistance built into the cylinder itself.
Which brands do you install?
Medeco, Mul-T-Lock and Abloy are our standards — all serviceable, all with genuine key control.
Will it fit my existing door?
Usually yes — high-security cylinders retrofit into most existing mortise cases and deadbolts without altering the door.
