A keyless entry door knob is a type of door lock that allows you to enter a building without using a physical key. Instead, you use a code, a key fob, or a smartphone app to unlock the door.

Keyless entry door knobs work by using a wireless signal to communicate with a receiver that is installed inside the door. When you enter the correct code, or present the key fob or smartphone, the receiver sends a signal to the door knob to unlock it.

There are many benefits to using keyless entry door knobs, including: nn- Convenience: You don't have to carry around a physical key, which can be lost or stolen. n- Security: Keyless entry door knobs are more secure than traditional locks, as they are more difficult to pick or bump. n- Automation: You can set your keyless entry door knob to lock or unlock automatically at certain times of day, or when you are away from home, giving you peace of mind.

There are a few things to consider when choosing a keyless entry door knob, including the type of lock (code, key fob, or smartphone), the features (such as automatic locking and unlocking), and the security level. You should also make sure that the keyless entry door knob is compatible with your door and that it is easy to install.
