Mul-T-Lock
Authorized Mul-T-Lock dealer — MT5+, Interactive+, Hercular.
Mul-T-Lock is the patented-key platform we install most for high-security residential and commercial jobs across Montréal, Laval and Longueuil. The MT5+ platform (patent through 2030+) uses a 5-pin telescopic key, hardened-steel drill inserts, anti-bump sliders and a keyway that can't be copied at a corner hardware store — new keys only cut against your signed authorization card.
What we install
- MT5+ patented cylinders — rim, mortise, deadbolt, padlock formats
- Interactive+ platform for buildings and master-key systems
- Hercular Grade 1 deadbolt with reinforced strike
- Junior padlocks and Traveller portable padlocks
- Cylinders keyed to a shared master across residential and commercial doors
