A smart lock is a keyless entry system that allows you to secure or unlock your door using a mobile app, key fob, or by entering a code on a keypad. Smart locks often integrate with home automation systems and can be controlled remotely, enabling features such as:

1. Remote Access: Lock or unlock your door from anywhere using a smartphone app.
2. Keyless Entry: Use a PIN code or smartphone instead of a traditional key.
3. Access Logs: Track who enters and exits your home and when.
4. Guest Access: Provide temporary access codes for visitors or service personnel.
5. Integration with Smart Home Devices: Often works with voice assistants like Alexa, Google Assistant, or home security systems
