Signstek Keyless Entry Door Lock,Door Knob with Keypad，Smart Code Door Lock,Mute Mode,Passage Function, Easy to Install,Satin Nickel

Works very well and is quite solid I have put on my shed weather permitting time will tell

Clean, easy, simple to program simple to use. It works perfect for the cleaning closets in the Airbnb unit units.

Nice build quality and easy to install. Very ergonomic design that makes entering the passcode and turning the knob open very smooth and fluid.

This lock fitted easily into the standard lock holes with very little work required to fit perfectly. Easy to assemble and works perfectly

For adults or infrequently opened doors that you don't want to drill another hole in this knob is fine, but since the design only stays unlocked for 5 seconds each time in order to make the batteries last it wasn't ideal for the main entry. Initially this was intended for a front door so kids didn't have keys to lose. I thought it would be like a power-deadbolt where once you enter the code it is unlocked until you lock it again. In fact pushing buttons is required each time you want to open the door from the outside. Yes it is possible to enter a key sequence which makes any button open the door until you enter another sequence to return it to full coded entry, but this is too complicated for kids. For our door that is used frequently a better choice was a regular doorknob with a code-entry deadbolt even though it required drilling to install. This doorknob ended up on the shed where it is perfect.
