Keyless Entry Mechanical Deadbolt Lock – 100% No Batteries, 304 Stainless Steel, 4-8 Digit Code, Key Override, For Homes, Offices And Schools

About This Product

This keyless entry deadbolt is a game-changer for anyone who hates digging for keys.

It's 100% mechanical – no batteries, no wiring, no electronics to fail.
You set a 4 to 8 digit code (with no repeated numbers, and you can enter them in any order for extra security) and you're good to go.
It also comes with a physical key, so you have a backup if you ever forget the code.

The lock is made from 304 stainless steel, which is extra hard and corrosion-resistant – way tougher than standard zinc locks.

The keypad is wear-resistant too, so it won't leave telltale signs of which numbers are pressed most often.
It fits standard doors with a thickness of 1-3/8 to 2 inches, and the backset can be 2-3/8 or 2-3/4 inches.

The maximum borehole diameter is 2-1/8 inches.

Important note: this lock does NOT lock automatically – you have to turn the knob to lock it.
That's a pro for some (you can come and go without re-entering the code) and a con for others who want auto-lock.
Just depends what you prefer.

Installation takes about an hour and works on left/right and inward/outward doors.
Solid, secure, and totally battery-free.
