Kwikset 985 15 Smt Cp K4 V1 Double Cylinder Deadbolt

Product Description

The KWIKSET 985 15 SMT CP K4 V1 is a Grade 1 double cylinder deadbolt from the Signature Series, finished in satin nickel. Double cylinder deadbolts require a key to operate from both the interior and exterior, making them a common choice for doors with nearby glass panels where a thumbturn would create a security vulnerability. This unit ships in a keyed-alike set of four, so all locks in the set operate with the same key. It includes SmartKey rekeying technology, which allows a licensed locksmith or qualified installer to rekey the cylinder to a new key without removing the lock from the door. Ball bearing anti-drill protection and concealed mounting screws add tamper resistance aligned with the Grade 1 security rating.

This deadbolt is suited for residential and light commercial applications on standard steel, wood, or fiberglass entry doors. The adjustable round-corner latch fits both 2-3/8 inch and 2-3/4 inch backsets, covering the two most common door preparations without requiring a separate latch purchase. The keyed-alike configuration is practical for multi-door residential properties, rental units, or commercial installations where a single key for multiple entry points reduces the number of keys a building manager or tenant must carry.

Installation Notes

Installation is performed by a licensed locksmith or qualified door hardware installer. Power down any adjacent electronic access control systems before working on the door assembly. Verify local codes and building requirements before specifying a double cylinder deadbolt, as some jurisdictions restrict their use on certain egress doors due to fire and life safety regulations. Follow the manufacturer-provided template for bore and latch hole alignment to ensure proper fit.
