Advanced Keying Options
Mul-T-Lock's cylinder applications enable a variety of keying options, together with a master keying hierarchy, to meet every home or organization's locking needs. These options range from traditional to innovative and are designed to provide ease of use and control over your locking systems.
Keyed Differ - is the simplest and most common keying option. A single key can only unlock a single cylinder, and no key can open more than one cylinder, ensuring you have maximum home security.
