Frequently Asked Questions
What makes a lock 'high-security'?
Patented restricted keyways, resistance to picking, drilling, and bumping, and manufacturing tolerances far tighter than standard locks. Mul-T-Lock and Medeco meet recognized high-security standards.
Can my Mul-T-Lock keys be copied anywhere?
No. Blanks are restricted to authorized dealers, and we require your key-control card and ID before cutting. That is what makes the system secure.
Will a high-security cylinder fit my existing deadbolt?
Often, yes. Many standard deadbolts accept a high-security cylinder retrofit, upgrading protection without changing the door's appearance.
Is a high-security lock worth it for a rental apartment?
If key control matters to you — no unknown copies from prior tenants — it is one of the strongest upgrades available, and you can take the cylinder with you when you move.
Do you service Mul-T-Lock locks I already have?
Yes. We install, rekey, and duplicate keys for Mul-T-Lock systems, provided you have the authorization card.
