Buying Guide: Key Purchase Considerations And Comparisons
When selecting a one sided door lock, consider the following factors to ensure you choose a model that fits your door and security needs:
- Exterior access: Choose between keyed exterior and non-keyed exterior based on whether you want remote access or simple interior operation.
- Backset compatibility: Most residential doors use backsets of 2-3/8″ or 2-3/4″. Verify your door’s backset before purchasing.
- Door thickness: Confirm the door thickness range (commonly 1-3/8″ to 1-3/4″ or up to 2-1/4″ for some models) to ensure a proper fit.
- Security rating: ANSI/BHMA grades (Grade 1, 2, or 3) indicate strength; for most homes, Grade 3 provides solid residential security.
- Maintenance: Non-electronic deadbolts require minimal maintenance, while keyed variants rely on mechanical components that benefit from occasional lubrication.
- Installation complexity: Some models offer straightforward retrofits with existing holes; others may require additional drilling or frame adjustments.
- Brand reliability: Reputable brands like Schlage and Kwikset provide consistent performance and easier replacement parts.
In comparative terms, non-keyed one sided deadbolts emphasize interior simplicity and reduced maintenance, while keyed exterior options enhance access control for front entry or exposed doors. Adjustable backsets and latch bolts improve compatibility across a wide range of door preparations, making installation smoother and less invasive. For households with children or pets, consider locking mechanisms that balance security with ease of use from the interior side.
