HAIFUAN Digital Keypad Door Lock with Backup Keys, Electronic Keyless Entry by Password Code，Card, Key, (RDJ-F, V2.0)

I bought two of these and have installed them both on outside storage closet doors. They look good and both work just as advertised. The directions take a little figuring out for the programming. Kinda written in a backwards manner in places. The installation was great! Easiest combination lock I've put on - and I've done several Schlage models. Extra parts came along with this - including 3 keys and a screwdriver.Downsides? Hmmm, the keypad is not lighted - but not an issue for our location. This lock probably doesn't look quite as upscale as the Schlage model on my front door - but it still looks very good.Bottom line for me was the ease of installation and the perfect functioning of these locks for thirty days now.

I have been using this lock on my front door for for about 18 months. It has had no issues except that the latch broke after one year but I contacted the seller and they responded right away and sent me a replacement and a spare. The lock body is very solid and the buttons respond accurately. The buttons also do not lose the numbers to wear like some others. I bought this because it cannot be picked or bumped by means of the bypass key. It does have hidden bypass key opening but the key is a shape that I have never seen before and neither would any criminal (I have cut a lot of keys while working at a hardware store). Having said that, it is not a dead bolt and does not offer the security of one. It is extremely convenient to never wonder if you or your kids remembered to lock the door. The battery life also seems good. I have had to replace the batteries only twice in 18 months and we use the lock probably an average of 20 times a day. It also has a low battery alert that you can't miss.

This is a great lock. True, I just installed it today but it is very stout - heavy stainless steel, it has an ability to have digital codes up to 13 digits where the correct number in the correct sequence must be entered. It also allows up to 9 users with different codes. It is very easy and very straightforward when it comes to changing the codes. And the lock is complete with 3 keys in the event there is a need as well as a way to power it externally... which I can't figure a use for but it is there. And if you forget everything, there is a way to reset the system - albeit you have to work a bit to do that. It is relatively easy to install and has rubber type mats designed to go between inside and outside knobs, thus protecting the door and securing the latch from water intrusion. However, the entire inside of the outter lock is covered with a steel plate which in its self makes the unit water resistant. Well thought out and heavy duty ... this system met my needs and then some. You will need 4 AA batteries...

Took a long time to install due to weatherproof rubber backing to them that was an issue trying to install it with that. I went on YouTube to watch the install. Easy to use and works well after you finally get it installed.

Installed about 4 months ago and it worked great. Then I came home the other day and it wouldn't open with the code. I had the key on me and tried to open it manually and even that wouldn't open it. I had to break into my own house.

The lock arrived a day early (1 day from the day I ordered it). It appears quite hefty. We are installing it outdoors so I may have to update this review for how well it holds up over time in South Texas weather. However, as of installation we followed other reviewers tips in setting up the code beforehand, inserting the 4 AA batteries before installation and we had to very slightly modify the previous indentation of the faceplate because these corners are sharp whereas previous faceplate was rounded (exacto knife did the job quite nicely). We agree that the instructions leave something to be desired. However, the instruction booklet's diagram to determine which of the door latches was the right length was useful.

It works beautifully and smoothly. The install was a bit tricky because it's difficult to line up super small holes between the front assembly and the back piece. Two sets of hands are pretty much required. It's beautiful, quiet and stylish. I'm concerned about replacing the batteries, as that's the only thing I'm not looking forward to.

Item went in a standard door configuration nicely. Only thing I had to replace was the part that goes on the edge of the door. You are given 2 different sizes with out any explanation which to use. I used the shorter one got lucky and the door works ok. I did have a little trouble figuring out how to get battery compartment loose, there is a little pin at the base of the inside mechanism you have to push down. Electronics for some reason didn't want to accept a second code after I put in the primary one but after messing with it I finally got it in. I still don't know what the hell I did to get the unit to accept the second code. There isn't any explanation for the wire gizmo that comes with the unit except a reference that it will open the lock if the batteries go dead.
