Product Identity

The Master Lock BCCO0615 is a mechanical knob lockset designed for residential entrance doors. It carries an ANSI Grade 3 rating for light-duty use and features a Biscuit style with a satin nickel finish. The lock operates with a KW1 keyway and includes two keys.

Sustained Operation

Under repeated daily use the Grade 3 construction provides standard residential security for entry points. The steel mechanism is built to handle normal household traffic cycles without the heavier-duty components found in higher-grade hardware. Performance remains consistent for typical home entry demands.

Build and Fit

The lockset fits doors between 1-3/8 and 1-3/4 inches thick and accommodates both 2-3/8 and 2-3/4 inch backsets with a 2-1/8 inch crossbore. A 1-3/4 by 2-1/4 inch strike plate is included. Builders needing a different keyway or a higher security grade should consider other options.

Questions about this item

Does the mechanical knob lockset generate any noise or heat during continuous daily use?

No, the purely mechanical entrance lockset has no motor or electronics, so it produces no audible noise or heat while operating.

What door preparation must already exist for this Grade 3 lockset to install correctly?

The door needs a 2-1/8 inch crossbore, a backset of either 2-3/8 or 2-3/4 inch, and a thickness between 1-3/8 and 1-3/4 inch.

Will the supplied KW1 keyway work with the existing Master Lock cylinders on my other doors?

Yes, the lockset uses the common KW1 keyway, so it can be keyed alike with other Master Lock hardware that shares the same keyway.
