A keyless entry door lock is a modern security solution that allows access without using a traditional key. It typically operates using a keypad, touchscreen, fingerprint scanner, or smartphone app. This eliminates the need to carry keys and reduces the risk of losing them. Many models offer customizable codes, allowing multiple users to have unique entry credentials. Some advanced locks feature Bluetooth or Wi-Fi connectivity for remote access and control. These locks often include auto-locking and tamper alerts for enhanced security. Installation is generally straightforward and compatible with most standard doors. Battery-powered, they usually have low-battery alerts to ensure consistent operation. Keyless locks offer convenience, improved security, and smart home integration.
