Smart Lock FAQs

Typically 6-12 months of normal household use on standard AA batteries, though this varies by model, WiFi usage and how often the lock is used. Most well-reviewed locks give a low-battery warning through the keypad or app well before the batteries actually die, giving you time to replace them before being locked out.

Every smart lock on this hub includes either a physical key override or an external battery-jump contact (typically a 9V battery held against terminals on the outside of the lock) specifically for this scenario. Check which backup method your specific lock uses and keep the physical key or a spare 9V battery accessible before you need it, not after.

Yes — a keypad-only lock like the TEEHO TE001 never uses WiFi in the first place, and even WiFi-capable locks like the Schlage Encode continue working locally via keypad or fingerprint if the WiFi connection is down; you simply lose remote access and app notifications during the outage, not the ability to lock and unlock the door.

A reputable smart lock from an established brand uses encrypted communication and adds real security measures like lockout after repeated failed code attempts, similar in principle to how a bank card locks after too many wrong PIN entries. No connected device is completely immune to attack, but buying from a known brand with a track record of security updates meaningfully reduces the practical risk compared to an unrecognized generic listing.

Most smart locks, including every one ranked on this hub, retain a traditional key cylinder as a backup entry method alongside the keypad, fingerprint or app — a small number of fully keyless designs (like the Nest x Yale Lock) remove the keyhole entirely in favor of a backup code system instead. Check the specific model if a physical key backup matters to you.
