Do smart locks work during a power outage?

Smart locks run on batteries, not household power, so a power outage does not affect them directly. However, a prolonged internet or Wi-Fi outage can disable remote app access, which is why most models keep a keypad code or physical key as backup.

How long do smart lock batteries last?

Most Wi-Fi smart locks last anywhere from six months to a year on a set of batteries, depending on usage and whether Wi-Fi is used constantly. Nearly all models warn you in the app well before the batteries actually die.

Can I install a smart lock myself?

Retrofit locks like the August are designed for a no-tools, few-minutes installation over an existing deadbolt. Full deadbolt replacements like the Schlage, Yale and Kwikset locks typically need a screwdriver and about 20 to 30 minutes, and are designed to fit standard door prep without extra drilling.

Are smart locks vulnerable to hacking?

Reputable brands build in encryption and undergo independent security testing (Schlage, Yale, August and Kwikset all publish certifications for their electronic locks). Using a strong Wi-Fi password and keeping the lock's firmware updated through its app are the most effective ways to reduce risk.
