May need a pro Locksmith for external doors

Convenience needs a backup

Biometric entry can be useful, but it should never leave you locked out or make emergency exit harder.

Check before buying

  • Manual key, keypad or backup power options.
  • Weather rating and door compatibility.
  • How users are added and removed.
  • What happens if the battery dies.
  • Whether the lock meets your insurance expectations.

Safety note

For external doors, fire escape and insurance matter. Use a locksmith where the lock affects the main security of the home.
