Smart locks are more secure than traditional locks due to advanced encryption and authentication technologies. They are also more convenient, as they eliminate the need for physical keys. Many smart locks also integrate with home automation systems, allowing them to interact with other devices like smart cameras, alarm systems, and lights.
