Kwikset 405BL-S Balboa Keyed Entry Lever

The Kwikset 405BL-S Balboa is a keyed-entry door lever for exterior or secured interior doors. A key operates the exterior side, while the interior turn piece locks and unlocks the door from inside.

This lever uses a SmartKey Security cylinder. SmartKey Security lets the owner re-key the cylinder to a compatible Kwikset KW1 key without removing the lock from the door. The adjustable latch accommodates common 2-3/8 and 2-3/4 backsets, and the trim is intended for standard residential door preparation.

The lockset includes the keyed exterior trim, interior turn-piece trim, and the latch/strike hardware identified by the selected product configuration. Use the linked installation and specification documents to confirm the exact faceplate, strike, and keying configuration supplied with the selected variant.
