HAIFUANDigital Door Lock,Unlock with Remote Control, M1 Card, Code and Key,Handle Direction Reversible

I love this lock! It meets or exceeds my expectations, both in quality/craftsmanship, and ease of installation. The recent 5 hour sale where the sale price fell below $100 made it a bargain. Believe it or not I am using this lock on our bedroom door. My sister in law (just retired) will be coming to live with us in a few months. She will have a lot of time on her hands, and I have been forewarned by her children as well as other family members that due to her nosy nature she wouldn't think twice about exploring our personal space.The lock we replaced only locked from the inside (but could be opened with a paper clip on the outside), and I also did not want to be walking around with a bunch of keys so this type of lock seemed like the logical choice. I read an earlier review that the combination keycodes would have to be at least six digits and I am okay with this, using six digits that I would never forget. I also purchased a five pack of the 12 volt batteries needed for the remote control (other Amazon users have done the same) as it is not a common 12 volt battery and may be hard to find at the box hardware stores. I also like the fact that the lock speaks when the door is locked or unlocked, and that the pretty blue number pad is not always lit up (to draw attention to itself). Finally, the most important thing that I can leave you with is, don't throw out the allen wrench(s) that come with the lock. You need them to reverse the handle and to open the battery compartment to replace the 4 AA batteries (not included) which power the lock.

I love this lock. It perfectly fit our escape room purpose.The instructions were very good. A template for the door was even provided. It WILL be necessary to cut an additional hole in the door, but the template makes it easy. The reason for the additional hole is that the lock keypad is on the front of the lock and the batteries are on the other side of the door. I really like that the battery pack uses an Allen wrench to open the cover. This makes it much more secure than just pressure to open or using a Phillips screwdriver.It has a feature called passage mode that works great for our escape room as you don't need to keep entering the code. With passage mode programmed on, the door stays unlocked until you press the # key a second time after entering the code. This might not be something that you may typically want to be turned on, but it works great for our escape room guests.My only complaint is that the remote control that comes with the device uses an odd battery, not the typical CR2032. This is like a short Double A. Unfortunately the type of battery required is not mentioned, or I missed it, in the instructions or the case of the remote control. This is not significant for our use but could be of use in personal use.The code can be up to 10 digits in length, which is awesome. It also allows you to enter random digits before and/or after the code to prevent someone from seeing the exact code you are using. I believe it allows up to 20 characters for this feature, which includes the actual code. Thus you could use 5 random digits before and another 5 digits after along with a 10 digit code if you wanted to confuse someone that may be watching while you enter the code.One additional feature worth mentioning is that you can turn the handles around by using an Allen wrench. This means you can easily install the doorknob on the right side or left side of the door. Just remove and turn the handles 180 degrees on each both sides to prevent it hitting the door jam.A CON is that the key is NOT a standard key and copies cannot be made. I believe another reviewer commented on this. It is a semi-circular key that is inserted on the side of the cylinder and as such is not something that your typical key cutter/locksmith could duplicate.I've attached a photo of the keys so you can hopefully see the curve on one side and the key grooves on the second side. I've also included a photo of the battery container for the remote so maybe you will know the type of batter required.

I just had a chance to install this and I really like the way it looks and operates! The instructions were obviously written by someone who's first language wasn't English but I was able to follow them. I installed this on a commercial steel door that already had a commercial lockset installed. One of the problems I had was that my old lockset was larger than this one so I had to fabricate a backplate to cover the holes. I was able to do this but many people will not. If installed on a standard residential type door this should work fine and cover the holes. Milling the door is a bit tricky for the slot that the wire goes through. I milled it per the template but this hole really could be rectangular and be cut with a jig saw if necessary. I'm not sure about the longevity of this lockset yet but I would think it will do well since it's stainless steel.Another thing to note is that it needs 4-AA batteries and they aren't included. the key fob also needs a special battery which I have yet to locate. Hopefully it will be readily available. I don't really plan to use it though so I'm not in a hurry for that battery.I would recommend this lock for it's appearance, price, function and features.

This lock worked great for about 2.5 months. Then, even though the signal was being passed from the key fob to the lock, the mechanism that engaged the handle to allow opening stopped working.I emailed the company early last week, their webpage says 3 day turnaround on customer service, I haven't heard a peep from them. And then last night after I put my keys in my valet tray after being in my new garage (using an actual key on the handle/lock that came with the garage which I had previously replaced) the piece connecting the key fob to my key chain broke. All in all I'd say that this whole setup is GARBAGE. As far as I can tell I am out about $120 including the lock and extra fobs we bought. DO NOT BUY THIS.
