FAQs About Mul-T-Lock Lock Service

Can Mul-T-Lock keys be copied anywhere?

No. Mul-T-Lock keys use patented profiles, and copies are made only for authorized holders. That is a large part of the security they offer.

Can you fit a Mul-T-Lock cylinder into my existing lock?

Often, yes. Many deadbolts and mortise locks can take a Mul-T-Lock cylinder, which upgrades security without replacing the whole lock.

Do you repair Mul-T-Lock locks?

Yes. We diagnose stiff or damaged Mul-T-Lock locks and repair or replace the cylinder as needed.

Is Mul-T-Lock good for a front door?

Yes. It is a common high-security upgrade for main entry doors where pick and drill resistance matter.

Are you a Mul-T-Lock authorized dealer?

No. 911 Locksmith is an independent local locksmith. We install and service Mul-T-Lock locks, but we are not affiliated with or endorsed by Mul-T-Lock or its parent company.
