The YL-99 is a battery-powered keypad door knob that replaces a standard knob and lets you enter with a passcode instead of a key. It holds one master code and nine user codes of up to 15 digits, has a backlit keypad, a mute mode to hide keypresses, and an adjustable latch that fits 2-3/8 in or 2-3/4 in backsets. It suits rentals, home offices, garages and back doors where handing out and losing keys is the problem. Against smart deadbolts it is simpler and needs no hub or app, but it has no remote unlock, no auto-lock scheduling and no audit trail, and it runs on four AAA batteries with an emergency power option.

Buyers rate it highly, and the praise centers on easy installation and reliable code entry. Complaints are few and mostly about battery life and the lack of smart features.
The YL-99 is a keyless electronic door knob with a digital passcode lock. It opens with a code entered on a keypad, so no key is needed. It supports 1 master code and 9 user codes, and each passcode can be up to 15 digits long. The keypad is backlit for entering codes in the dark, and the backlight turns off when the knob is not in use.
The knob is made of bronze with an oil-rubbed bronze finish and has a round shape. A mute function helps keep the code from being seen or overheard. It is waterproof and can be used indoors or outdoors. An emergency power supply is included for when the batteries run out.
The knob rotates freely, so it fits both left-handed and right-handed doors. An adjustable latch fits a 2-3/8 in (60 mm) or 2-3/4 in (70 mm) backset. It fits most standard doors, including entry, exterior and interior doors, and installs with just a screwdriver.
