VEVOR Mechanisch sleutelloos toegangsdeurslot, 14-cijferig toetsenbord, dubbelzijdig ingebedde buitenpoortdeursloten set met toetsenbord en handvat, waterdichte zinklegering, eenvoudig te installeren,

So far, so good. I had one issue that I figured out and thought I'd pass along to people. I noticed it worked for the first week (had a contractor install it who recommended it). Set it up so one side requires a passkey and the other just opens with the latch pull. I noticed after a week, the latch pull that didn't require the passcode just locked up. Anyway, if you press 'C' it unlocks it. Also, the locking mechanism is a bit finicky and gets stuck inside the unit. You have to pull the handle up to force it out.

Thanks to everyone who shared their experiences! The best review for me was from a person who basically said that "If you are mechanically inclined, you won't have any trouble installing this." That was my experience. The lock arrived yesterday and I did a "PART 1" installation while watching TV. Of course, I had already watched whatever videos I could find. PART 1 was to put the lock together and test it's operation while holding it in my hand - not on a gate or door. I set up a combination to get IN the gate and a separate combination to get OUT of the gate. It all worked flawlessly and predictably.[After buying 4 of these] As mentioned, the PART 1 (the lock itself) was great. PART 2 is getting the thing installed on my metal gate... that's a whole different story. I returned Lock #2 and Lock #3 because of various installation challenges because I bought USED locks to save money. One was missing parts and the third one was designed to teach me. The spindle part needs to be modified to stay at 60mm. One way was to use a bolt and nut to lock it into position. Another way is cut a piece of plastic (a pen) tube and glue it in place. The other challenge was to ensure that both halves of the lock line up easily and precisely, which was not the case for me until I cut the opening of my gate lock area using an angle grinder (Dremel tool). Doing those two things allowed Lock #4 to be installed "easily". In fact, so easily that I went back to my first lock and made sure that it fit "better" by grinding a larger path for the lock. Bottom line is that, after the four locks, I have two that are working flawlessly. Are the locks any good? I give 5 stars to my two locks. I learned a lot and I could install these very quickly if I needed another one. If they "hold up" over time, and they should because they a simple design, my rating would stay forever. I bought a tube of black caulking to make the locks beautiful on my gates.PART 2 is partly done where the lock will be placed on a gate. It's almost done - just need some "fine tuning" to get everything smooth. I may do a video on the next one because it really is simple (thanks to all the reviewers).The lock install consists of the following steps:Step 1. Unpack the parts.Step 2. Set the combination. Decide on the combination, say 1,2,3,4. On the back side of the lock, use a small screwdriver to rotate the "dials" so that the "dot" point toward the numbers (1,2,3 & 4).Step 3. Set up the handle directions by unscrewing the handle using a small screwdriver. Move the handle to the correct direction for opening (you know what this means... left, right, or whatever). Screw down the handle. There's a square thing where the hole is that has an arrow. Rotate it point in the same direction as the handle.Step 4. Test the lock by pushing down the buttons (1,2,3,4) and turn the handle. That's it for this first part of setting up the lock.PART 2 is not hard and the manual is fair. But, as mentioned, it's reasonable and logical.Five stars? So far, solid.

Terrible quality

Wish it would lock more constistantly sometimes you have to rattle the handle to get it to lock. It would be much nice if the numbers light up.

Note proper instructionsKind of flamsy product I end up hiring a professional locksmith to install it.and he was struggling with it.
