Standard deadbolts keep honest people out. High-security cylinders from Mul-T-Lock and Medeco are built to resist picking, drilling, and bumping — and their restricted keyways mean keys cannot be duplicated at a hardware store. Every copy is authorized and tracked.
For landlords, businesses, and anyone who has lost track of spare keys over the years, a restricted keyway ends the uncertainty permanently. The cylinders usually retrofit into your current hardware, so upgrading rarely means new doors or visible changes.

What makes Mul-T-Lock different from a regular deadbolt?
Two things: the cylinder resists picking, drilling, and bumping far beyond standard locks, and the patented keyway means keys can only be copied with your authorization.
Can you upgrade my existing locks to Mul-T-Lock?
In most cases yes — the cylinders retrofit into standard deadbolt and mortise preparations without replacing the whole lock.
What is key control?
It means no one can duplicate your keys without your permission. Every copy is logged and authorized by you.
Are high-security locks worth it for an apartment?
If you have ever wondered how many copies of your keys are out there, yes. One upgrade ends that question permanently.
Do high-security locks need special maintenance?
No — they operate like normal locks day to day. We recommend periodic cleaning and proper lubrication, which we can handle.
