What the AI looks for in Deadbolts
- ANSI/BHMA grade
- Grade 1 for exterior doors; Grade 2 is the minimum you should accept The grade reflects cycle, bolt-strength and impact testing, and the grade gap is largest on deadbolts.
- Bolt throw
- Full 1-inch throw A short throw is easier to spread out of the strike when someone forces the door.
- Strike reinforcement
- Strike plate fixed with screws long enough (about 3 inches) to reach the stud behind the jamb Most kick-ins fail at the jamb, not at the bolt.
- Backset and bore
- Match 2-3/8 or 2-3/4 inch backset and a 2-1/8 inch bore; most units are adjustable These measurements decide whether the lock fits an existing door prep without new drilling.
- Keyway
- Match the keyway of your other locks (for example Schlage SC1 or Kwikset KW1) if you want one key Mixed keyways cannot be keyed alike.
Brands that matter
- Schlage: Mechanical Grade 1 residential deadbolts and a widely supported keyway.
- Kwikset: SmartKey rekeying and wide availability, mostly at lower grades.
- Yale: Strong in keypad and smart deadbolts.
- Medeco: High-security restricted-key cylinders.
- Baldwin: Decorative solid-brass deadbolts that match its handlesets.
What to avoid
- Unbranded deadbolts with no ANSI/BHMA grade listed
- Installing any deadbolt with the short screws in the strike pack
- Double-cylinder deadbolts on doors used as an exit, where local code may prohibit them
Questions
Single or double cylinder?
Single cylinder (thumbturn inside) suits most homes. Double cylinder only makes sense next to glass, and it can slow an emergency exit.
