Smart Locks: Keyless Entry for People Who Lose Their Keys

If you've ever locked yourself out, fum‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍bled with keys at the front door, or worried about whether you left the door unlocked, a smart lock might be one of the most practical upgrades you can make to your home.

Smart locks let you lock and unlock your door using your phone, a code, or your fingerprint — no key required.

What Is a Smart Lock?

A smart lock replaces or attaches to your existing deadbolt and adds digital unlocking options. Most smart locks support one or more of these methods:

Keypad code — punch in a 4–8 digit PIN to unlock (no phone required)
Smartphone — unlock via an app, Bluetooth, or Wi-Fi
Voice command — "Hey Alexa, lock the front door"
Auto-unlock — the door unlocks when it detects your phone approaching
Fingerprint — some models include a fingerprint reader
Traditional key — most smart locks still have a physical keyhole as a backup

Why Seniors Find Smart Locks Helpful

No more lost keys — a PIN code never gets misplaced
Check if you locked up without getting out of bed or turning the car around — the app tells you
Lock or unlock remotely — let in a caregiver, family member, or repairperson when you're away
Temporary codes — give a house cleaner or family visitor a code that expires automatically
Auto-lock — set the door to lock itself after a certain number of minutes so you never accidentally leave it unlocked
Activity log — see a record of who came and went, and when

Security Considerations

Smart locks are generally secure — often more secure than traditional locks:

Most use AES-256 encryption (the same standard used by banks)
They still have a physical key slot as a backup
Look for locks with ANSI Grade 1 or Grade 2 certification for mechanical strength

Tips to stay secure:

Choose a PIN that isn't a birthday, anniversary, or other guessable number
Change codes when someone who had access to your home no longer needs it
Keep the lock's app updated on your phone
Enable two-factor authentication on your smart lock account
