Upgraded Electronic Keypad Door Knob and Lock Set by SoHoMiLL

This door knob is not an automatic dead-bolt lock! After entering a valid code, you have only 3 seconds (indicated by a 3-second beep) to turn the keypad knob to unlock. If you don't turn the knob within this 3-second window, the lock will revert to the "locked" position. This "auto-lock" security feature is designed to prevent you from forgetting to lock the door.

This is a spring latch lock, without a motor, that lasts longer than a dead-bolt. Again, you must turn the keypad knob to unlock the door.

You can install this door knob yourself - no professionals required. Everything is included; you just need a screwdriver. No more worrying about losing, forgetting, or making extra keys. The lock fits standard door knob installation holes.

You're free to add, change, or delete user codes as needed. This lock works for exterior, interior, side, or garage entry doors. Each family member can have their own user code for access. Coming home late at night? No problem - the keypad is illuminated by LED, so you can see it in the dark. If you have visitors, set a temporary code for their stay. No spare keys required.

Going for a jog or a ride? No need to carry a bulky key chain or worry about losing your keys. Just press your code and you're home. You can also give your neighbor or pet sitter a user code while you're away, then delete it when you return. For Airbnb, rental, or vacation home owners, this lock can reduce the costs of replacing locks and making extra keys. When a renter moves out, simply delete or change the code.

While this door knob is designed for outdoor and indoor use in temperatures from 6°F to 102°F, it's recommended to be installed under a porch or some kind of overhead cover, and it should not be directly exposed to heavy rain, snow, or melting ice.

In summary, this lock offers:

✅ Easy DIY installation - no professionals needed, everything included ✅ Maximum security with 3-second auto-lock from the outside, alert for every entry attempt, and no hacking risk ✅ Reliable and failproof, with backup mechanical key and low battery warning ✅ Flexible management - master code, up to 8 user codes, and programmable code, all controlled by the master ✅ Easy fit for left or right-hinged doors, replacing most existing knobs
