Mul-T-Lock Interactive+ — restricted-keyway high-security
Mul-T-Lock Interactive+ is a patented restricted-keyway high-security cylinder platform used in commercial, government, and high-end residential applications across Greater Vancouver. The defining features are a telescoping pin design (each key cut moves an internal pin within a pin within a pin), a sidebar mechanism that adds a second authentication axis, and a restricted-keyway profile that legally cannot be duplicated without an authorized dealer and a signed key card.
The result is a cylinder rated against picking, bumping, and impressioning at the highest commercial grades. Combined with the patented key control, it's the platform we recommend for any property where you need verifiable answers to "how many copies of this key exist and who has them."
