Kwikset 85174-003 Cylinder Smartkey SC1 Silver Finish

Product Description

The KWIKSET 85174-003 is a replacement cylinder designed for use with single cylinder deadbolts and electronic deadbolts equipped with the SmartKey re-keying system. This cylinder uses the SC1 keyway and ships in a silver finish. It is a direct service component intended for locksmiths and experienced installers who need to replace a worn, damaged, or keyed cylinder without swapping the entire lockset. The SC1 keyway is one of the most widely used residential keyways in North America, making key duplication and service straightforward. At 0.1 pounds and a compact footprint, this cylinder is a simple stock item for any service van.

This cylinder is suited for residential door hardware applications where a SmartKey-compatible deadbolt cylinder requires replacement. Typical scenarios include post-break-in cylinder replacement, re-keying service calls where the existing cylinder is damaged beyond SmartKey re-key capability, or upgrade installations where a matching cylinder finish is required. The silver finish is appropriate for door hardware in standard residential entry configurations. This is a single-unit replacement component sold individually.
