User questions & answers

Question:	Can I use this on an outdoor gate, exposed to rain/snow? Is it waterproof
Answer:	Hopefully it's still under warranty because the locks are designed to remember settings when tje batteries die or are replaced without any additional programming
Question:	I bought two. one works fine. i can enter the code and it unlocks. the other one beeps three times when i press a button, then i can enter the code
Answer:	I used this to replace a Kwickset keyless lock, the key part (the tumbler part that has the keyhole in it) I was able to take out of the Kwickset and use in this lock. So I didn't have to change keys and all of my outside doors have a common key. So I have the same key for 3 doors. I am also going to buy 2 more to replace the rest of my locks and do the same thing (swapping the tumbler part)
Question:	Will this work on my 3” door
Answer:	Absolutely right, each family member can own his/her unique password. What's more, if you run Airbnb, a keyless keypad deadbolt lock will save you tons of troubles
Question:	Can you lock the door from the inside
Answer:	Guarantee is that it’s easy to install and works great on the door
