A long bolt typically refers to the extended throw or bolt length designed to engage more door edge into the strike plate, enhancing security on thicker doors or misaligned frames.
Grade 1 offers the highest level of residential security, but Grade 2 or ANSI/BHMA Level 3 models can be sufficient for many homes while maintaining good durability and value.
SmartKey-enabled locks can be rekeyed quickly and may require periodic lubrication and gasket inspection to maintain smooth operation.
Most exterior doors are compatible, but ensure the door thickness, bore hole size, and backset match the lock specifications before purchase.
Look for rust-resistant cylinders (brass) and weatherproof exterior finishes that tolerate rain, humidity, and temperature changes.
