HAIFUAND6300 Bluetooth Digital Door Lock Satin NickelOpen by CardCodeKey& APP Compatible with Alexa via Gateway (HFAD6300B-R)

Once installed this lock has worked well and looks great. This lock requires 3 holes in door and does not fit standard pre-drilled doors with two holes. I installed by putting in a deadbolt with an external key in bottom hole of pre-drilled holes and the Haifuan lock in top hole. This requires drilling two additional holes above the pre-drilled holes. The written instructions are poorly translated and incomplete, but an average person should be able to figure out after a few tries. The Bluetooth App makes programming new codes easy and quick after a few repetitions.

I liked the looks of the keyless pad. What I didn’t like was that you had to put in six digits as a user code. I prefer to just have four digits to remember. That is what I have used for years on my door. I decided to return it and get another one with just four digits! It’s easier to remember with just four numbers!

This worked very well for a while, and now it stopped working. It won't lock anymore after each use. I contacted seller, and they asked for a video proof. I sent it but I haven't heard from them since several weeks have passed. Cannot recommend due to poor customer service.

This is a terrible lock. It doesn't work correctly. It stopped working after a week. I wouldn't recommend purchasing it.

I am ordering ore of these, we have installed one and it has worked awesome. The phone app and ekeys work great and easy for all our employees. We have the gateway as well so I can unlock anywhere I have service. Once I get everything up and working with 4 for door handles I will see what the difference will be and write another review.The install is a little harder than a normal door handle, but it is worth the effort.
