Overview
A keypad entry door knob that stores up to 50 numeric codes alongside a backup mechanical key, finished in matte black. It runs on 4 AAA batteries rated for about 18 months, with a USB-C port for emergency backup power, and carries an IP65 rating for outdoor exposure.
This is a keyless knob built around code entry rather than fingerprint or app control, which keeps setup simpler for households that just want to hand out a code instead of a key. The backup key cylinder is compatible with most standard mechanical keys, so a locksmith is not required if the electronics ever need bypassing.
- Up to 50 customizable 1-15 digit codes
- 4 AAA batteries, about 18 months of use
- Fits 1-3/8 to 2-1/2 inch door thickness
- IP65 rated, -22F to 176F operating range
Who it's for
Households, landlords or small offices that want to give out entry codes instead of physical keys, without needing an app or fingerprint system. Less suited to buyers who specifically want biometric or app based control.
Pros and cons
- Stores up to 50 separate entry codes
- Backup mechanical key works with most standard keys
- IP65 weatherproofing for exterior doors
- USB-C emergency power if batteries die
- No fingerprint or app control
Performance notes
Codes can be 1 to 15 digits long and up to 50 can be stored at once, which covers a household plus regular guests or staff without codes colliding. The keypad has a soft backlight for use at night, passage mode lets the door stay unlocked when locking is not wanted, and silent mode drops the beep for quiet operation. Power comes from 4 AAA batteries lasting roughly 18 months with a low battery alarm, backed by a USB-C port for emergency power when batteries die. The IP65 rating and a listed operating range of -22F to 176F point to genuine exterior use rather than indoor only.
