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.

It's been over 4 years since I bought this item. I am just now changing the batteries. I used standard alkaline batteries from BJs, nothing special. So, if you were to use lithium type batteries, who knows how long they will last.
There was a audible siren warning, along with a verbal notification letting me know it was time to change the batteries. This item has performed perfectly. Not a single problem. I put it on my garage to interior door. So, no direct weather. I live in Florida, so not too cold. The batteries are on the inside of the door, so not too cold/hot. My only gripe is that the remote control does not "latch" the lock open. It only stays open for a short time before it closes. Only a problem for me since I tried to use the remote in my car to open the door on my way into the house. I am not fast enough to press the remote, in the car, an make it to the door. Not a big deal. Also, it requires a minimum of 6 digits. It would be nice if you could use any number of digits. Great product. Money well spent.

Update: I just wanted to let everyone know that I save hotel room keys (and those waterproof wristbands from cruise ships) and program them with this door lock. To see if they work, I just place them near the keypad and listen for the error beeps. That way I know it read it and rejected it. Then, I just use the owner's manual instructions to "learn" the new card/wristband. The kids love it, since they now have their own cards.

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.

Lock seems well built. Has some quirks that may make it usable for some for their intended purpose.

I'd like to say I'm using this lock as the entry door lock for a 32 unit boutique hotel. I bought extra key fobs here for $25 for 100 of them that work great. Just search for YARONGTECH RFID 13.5MHZ ISO14443A MIFARE Classic 1K Key fob token Black color pack of 100.

So far I've only had 1 issue with the inside door handle getting stuck in the down position. I loosened the whole lock and I think I have fixed it. Some times too tight is possible when installing door locks.

Quirk 1. Not easy to put lock in passive mode where no fob or code is used to access the lock. If you are using it like I am for a hotel then you will have guests try and use the fob to unlock the door and if it's in passive mode it will just put the lock back into locked mode if the key fob is placed on the door lock to try and lock/unlock it.

Quirk 2. Cannot use codes less than 6 digits. I had an old code of 4 digits and this code cannot be used anymore on this lock because it has to be a minimum of 6 numbers

Quirk 3. Instructions say that lock can be unlocked 200 times one one set of batteries!? This doesn't seem like many times. I'm still on my 1st set of batteries and I'm curious how long it they will last.

PRO. The wireless remote lets me keep the door locked and open it from the front desk when guests approach the entry door. You can mount the remote with double sided tape under your counter top or in a specific location.

I'll update this review after a month or so.

The unit works as advertised. The problem I ran into is that it will not fit correctly in a door that already has a lock and a deadbolt. The unit interferes with the deadbolt. I had to install it upside down to get it to work correctly. This really isn't a problem since the door unlocks by remote control and the keypad is only used as a backup. The only other issue that I have is that it remains unlocked for only 6 seconds. Sometimes this is not enough time to get from the car to the door. The advantage of the remote is that you don't have to fumble for your keys but if you only have 6 seconds then you really still need to keep the keys in your hand and unlock it when you are close to it. I wish the time to stay unlocked could be adjusted. Other than that the unit is well designed and I am happy with my purchase. The ability to have separate codes to unlock it along with the remote control and the proximity cards are very useful.
