Copper Creek Ball Door Knob - Privacy Function - Antique Brass

No, this knob is specifically designed for interior privacy applications only and does not have a locking cylinder for external security.

You can unlock the door from the outside by inserting a coin or a flathead screwdriver into the small slot on the exterior knob and turning it.

ANSI Class 3 (or Grade 3) is a standard for residential door hardware, indicating basic performance and durability suitable for typical home use.

No, this privacy lock does not use a key. It is operated by a privacy button on the interior and a slot for emergency access on the exterior.

A privacy lock is for interior doors where a quick lock is needed, and it has an emergency release. A keyed entry lock has a cylinder that requires a key to lock and unlock from either side and is typically used for exterior doors.

Use a soft, damp cloth to clean. Avoid abrasive cleaners. Wipe dry immediately. The antique brass finish may naturally develop a patina over time.

This knob fits standard door preparations for interior knobs, typically requiring a cross bore hole and a compatible backset (usually 2-3/8" or 2-3/4"). The latch has a round corner design.

Check for obstructions in the mechanism or ensure the latch is properly aligned with the strike plate. Light lubrication of the internal mechanism may help if dryness is suspected.

Verify that the knob is correctly installed and that the internal mechanism is not binding. Ensure the door is fully closed when attempting to engage the privacy lock.

Gently insert a coin or screwdriver and try to rotate it slowly. Ensure no debris is blocking the slot. If resistance persists, the internal mechanism may require adjustment or professional assistance.

This may be a characteristic of the antique brass finish, designed to have a non-uniform appearance. If it's actual tarnish or damage, clean gently with a soft cloth. Avoid harsh chemicals.
