Best Locks for Home Security in 2026
A locksmith's guide to choosing the right locks for your home.
The best locks for home security are Grade 1 or Grade 2 deadbolts from trusted brands like Schlage, Kwikset, or Medeco. For added convenience, smart locks from brands like August or Yale offer keyless entry with strong security. Always use a deadbolt on exterior doors.
Understanding Lock Grades
The American National Standards Institute (ANSI) rates locks by grade:
- Grade 1 (Commercial)
Highest security. Withstands 800,000 cycles and 10 strikes. Best for homes requiring maximum security.
- Grade 2 (Residential Heavy-Duty)
Withstands 400,000 cycles and 5 strikes. Excellent for most homes. Our recommended minimum.
- Grade 3 (Residential Basic)
Withstands 200,000 cycles and 2 strikes. Basic security. We recommend upgrading from Grade 3.
