Mul-T-Lock® Interactive+
The definitive Grade 1 high-security platform with patented telescopic pins and true key control.
Mul-T-Lock has led high security for nearly five decades. As a fully authorized dealer and installer, Guardian Angel Security Group recommends the Interactive+ platform as one of the most reliable high-security solutions available for homes and businesses.
A Critical Security Alert
The original Interactive® platform lost patent protection in 2014 — meaning key blanks for it can now be legally produced by anyone, undermining key control. If you have the older platform, we strongly recommend upgrading to the currently patented Interactive+ or MT5+ to restore the integrity of your keys.
Telescopic Pin Tumblers
A pin-within-a-pin design requires internal and external shear lines to align simultaneously — exponentially harder to pick than any standard lock.
The Floating Disk Key
A spring-loaded pin interacts with a patented floating disk inside the key itself, creating a “virtual combination” that defeats 3D-printed and counterfeit keys.
Hercular® Grade 1 Deadbolt
Heavy-duty drill and pick resistant cylinder with an interlocking ball-bearing bolt that resists prying, kick-ins, and crowbar attacks.
Captive Deadbolt Option
Converts between single-cylinder (safe egress) and double-cylinder (maximum security) — ideal for doors with glass, without violating building codes.
The Key Order Card
Every system includes a credit-card-style authorization card with a magnetic code tied to your exact lock. As an authorized dealer we can only cut duplicate keys when the card is presented and verified — placing access management exclusively in your hands.
