Yes, many keyless locks work via Bluetooth or keypad without Wi-Fi. However, remote access and voice control typically require Wi-Fi or a hub.
Most keyless door locks use standard AA batteries, typically lasting 6-12 months. Some models have low-battery alerts and backup physical keys.
Yes, reputable keyless locks use encryption, tamper alarms, and secure protocols. Choose locks with ANSI Grade 2 or 3 certification for physical security.
