cylinders can be designed so their key combination can be changed without replacing the hardware?
The Mul‑T‑Lock 3‑in‑1 cylinder allows you to change the key combination using a working key. Once the changeover is done, any previous keys will no longer operate the cylinder.
This process can be performed up to 2 times on the same unit, giving landlords the flexibility to update the key set as needed while keeping the existing installation in place.
