### ⭐⭐⭐⭐ I am into this install 3 hrs so far- can not get to reset- where is the customer service
*by T***. on January 6, 2023*

I would like to know where my 1st review went. First I am into this now a total of 3 hrs. and I am NO Novice when it comes to locks. At this point I have gone thru 3 new batteries, and I still can not get this to Beeb once. I am still trying to get this to respond to resetting this, it has not yet turned Green. You must install the whole thing first, to reset the code before you can do anything else. It's awkward to stand halfway between the both sides of the lock in an open door, push a tiny button with a tiny tool and then be looking at the other side of the knob to see if it turns green....in the winter as the cold air rushes in. Why on earth does it require to be RESET???? What I would like to know is: why can't a person program it first, and then install it???? I am assuming that when the consumer needs to replace the battery that the lock remembers the programed codes. If not, there is no mention of this anywhere on the internet. So I now have a nifty looking knob, that doesn't lock. All the numbers light up, so I am assuming that the New battery I installed is working. And all those Utube digital content is way too fast, stop compressing the content. How about some content of Troubleshooting???? UPDATE- I see what happened, but no information exists to let you know this-- I had inserted the wiring in upside down. The white wire should be pointing towards the ground. They tired to put some red paint to indicate which way to put the wire into; but it's very faint.
