What are deadbolts used for?

Deadbolts are used with a door knob or lever when the door needs stronger security than the latch alone can provide.

They add a solid locking bolt for higher entry protection while the handle set manages everyday opening and closing.

Entry door combo

Adds stronger security above a knob or lever latch.

Stronger bolt lock

Uses a solid bolt for higher entry protection.

Controlled access

Keeps entry control tied to approved keys.

How to choose the right deadbolt

Deadbolt selection depends on door preparation, cylinder type, inside operation, keying needs, finish and whether glass is near the door.

Check the door setup

Check backset, bore holes and door thickness before choosing.

Choose cylinder type

Choose inside snib control or double cylinders near glass.

Confirm the finish

Match the finish to the door and nearby hardware.

Common reasons to replace deadbolts

Most requests to replace deadbolts begin with worn hardware, lost keys, changed access needs, or a lock that no longer works reliably.

Can you install or replace deadbolts?

Yes. We can install or replace compatible deadbolts after checking the door, frame, existing cut-outs, cylinder type and daily use.

Can you repair an existing deadbolt?

Yes. We can assess a stiff, loose, damaged or misaligned deadbolt and explain whether repair, rekeying or replacement is the better option.

Which deadbolt type do I need?

The right option depends on the door setup, inside operation, keying needs, finish and whether a single-cylinder or double-cylinder deadbolt is suitable.
