The short version: Schlage Encode is the senior-friendly default, large physical buttons, code entry, Wi-Fi for remote unlock by family, mechanical key backup. About $250. Skip fingerprint readers.

What a smart lock fixes

For senior homes, smart locks solve three real problems:

  1. Caregiver access, generate temporary codes for paid caregivers without giving out a key.
  2. Emergency responder access, adult child can unlock remotely if EMS arrives and the senior can’t open the door.
  3. Lockout recovery, senior who forgets their key can be let in remotely.

Our picks

1. Schlage Encode: best overall

Wi-Fi-enabled smart deadbolt. Code entry on physical buttons, Wi-Fi for remote unlock, mechanical key backup. About $230-$280.

Why we pick it: large physical buttons easy for arthritic fingers. Wi-Fi built in (no separate hub). Schlage’s mechanical reliability is industry-leading.

2. August Wi-Fi Smart Lock: best for keeping existing deadbolt

Mounts on the inside of an existing deadbolt. Doesn’t replace the deadbolt, works with the existing key. About $230.

Why we pick it: no exterior change to the door. Keeps the original key working for users who refuse to give up their key entirely.

Where it falls short: more complex install than direct-replacement smart deadbolts.

3. Eufy Smart Lock C220: best subscription-free

About $130. Local storage of access codes, no recurring subscription, fingerprint plus code entry.

Why we pick it: cheaper. No subscription. Works without internet for code entry (needs Wi-Fi only for remote unlock).

Where it falls short: smaller physical buttons. Skip fingerprint reader for senior users (dry skin issues).

What to skip

Fingerprint-only smart locks. Senior dry skin and arthritis hand position make fingerprint readers fail more often than younger users.

Smart locks without mechanical key backup. Battery dies, you can’t get in. Emergency responders can’t get in.

Setup for caregiver access

For senior homes with paid caregivers:

  1. Generate a separate code per caregiver.
  2. Set time-limited codes (e.g., Tuesday-Friday 8am-6pm only).
  3. Family receives notifications when each code is used.
  4. Rotate or revoke codes if the caregiver relationship ends.

What to do next

If you have an existing deadbolt you like: install August Wi-Fi.

If you’re replacing the deadbolt entirely: install Schlage Encode.
