High Security Locks

We install high security cylinders and deadbolts for doors that need more than a basic lock.

What makes a lock high security?

A high security lock has a more complex cylinder inside and a controlled key. Copies of a controlled key are cut only for the people on the account, not at any hardware store. We install brands like Medeco and Mul-T-Lock and fit them to the door you already have whenever we can.

When people call us for this

Can you use my existing deadbolt?

Often, yes. Many deadbolts take a high security cylinder in place of the standard one. If yours cannot, we tell you and quote a full replacement instead.

How do I get a quote?

Call us, or text a photo of the lock and the door edge. We give you a written quote before any work starts.

Frequently asked

Who can get copies of my key?

Only the people you name on the account. You decide who gets keys.

Do high security locks work with a master key system?

Yes. Buildings and businesses can have controlled keys and a master key together.
