Sliding Patio Door Handle Set with Key Cylinder and Mortise Lock, Full Replacement Handle Lock Set Fits Door Thickness from 1-1/2" to 1-3/4", 3-15/16” Screw Hole Spacing, Reversible Design(Non-Handed)

This handle/lock set fit my door well. I didn’t even have to change out the latch part. Once installed, it worked smoothly and has a sturdy feel to it. The installation does require some cutting of the flat, metal pieces that engage with the latch assembly. They are too long, likely to accommodate thicker doors so I’m sure it will need to be cut regardless of the type of door you have. I put the lever on one side and the lock set on the outside as they would be installed. Then I marked them both where they intersected in the middle. The idea is to cut them so they both engage the latch assembly. Cut them too short and one or both will not engage the latch assembly. Cut them too long and they will either not fully tighten down or will bind (or both) as they butt up against each other in the center.Once marked, I put them in a vice and cut with a dremel tool (as others have mentioned). If no dremel, a pair of clamping pliers and a hack saw will work too. It will be more of a challenge hold them while cutting though. Once cut to length, the rest is pretty simple. You may want to file off the burrs after cutting.It works great once installed. Key is smooth as is the latch engagement.I have been using it for a couple weeks now and no issues. I will update if anything changes.

Easy installation, perfect fit

Having removed and replaced a few parts of a sliding door handle and latch before, the overall install was pretty standard. As many others mentioned, the hardest part will likely be cutting the two metal bars (one for the inside, one attached to the lock) that insert into the latch. See the end of the this review for tips I used to make the install easier.It lines up with the price and does feel somewhat cheap when operating the interior lever to lock or unlock the door. It kind of moves freely for a bit before actually doing anything which just seems to be related to the design itself. You might have to play with the tightness of the two handle screws to get the best movement without the lever moving too freely or being too hard to move.The included lock feels pretty cheap as well and using the key feels really stiff. I think after a couple weeks of use it should break in, though.One nice thing that our prior handle didn't have is the ability to flip the actual lock around depending on the way your door opens. There's a metal bar with a screw in the exterior handle that you can remove to take the lock out and flip it. This is nice if you care about the orientation of the key when you insert it into the lock. Just a nice touch.Beyond the cheap feel of the lever and lock, the actual handles feel pretty good in use.Overall, it's not going to win any awards, but it's functional and relatively straightforward to install if you've replaced a handle and latch before.Install Tips:I would recommend a hacksaw for cutting the two bars since they're relatively cheap if you don't have one already. I used a clamp to hold down each piece and then took a few minutes to cut through the metal. It's not really hard, but something like tin snips won't work. Just hold each piece flush with the door edge so the metal bar goes over the latch area and then mark the halfway point. That's where you should cut. Start longer and work it down if you need to. The two bars should basically end up 50/50 inside the latch.As for the latch installation, I always put the latch into the "locked" position with a screwdriver before trying to insert it into the door. This way, you have something to grab onto when putting it into the door. Also - tie a string around the latch when it's sticking out and put a screwdriver through the lower handle holes from one side to the other in the door. Both of these should help prevent you from dropping the latch down into the door.Finally, you might want to get longer screws to attach the latch to the door. The included screws are really small and were maybe 1/3 of the size of my prior latch's screws. I was able to reuse the longer screws and it seemed to hold on a lot better.

So the directions is somewhat confusing & difficult & the video wasn’t helpful so I had to look up another video on installing this. For this to work you will have to get two pliers to cut the lock keys for them to fit together inside the lock mechanism. Once I did that it worked & I love it… Returned my lock that I bought from homedepot which was more expensive & cheap product that I had on beforehand which had broke. But so far I love that I can leave my house from the sliding glass door & lock it now.

Was very difficult to install. The instructions are terrible. Once it was completely installed it doesn't work well and have to be very specific with locking it, or else it will not latch properly.Edit: The wife was too kind. The instructions are garbage, the latch is unbelievably finicky, and the only reason we kept it was to avoid having to drive an hour to return it. I was able eventually make it function adequately.The latch side has no markings to assist for cutting, so you better have a cutting wheel or bolt cutters. The piece that attaches to the door frame itself must be positioned specifically in such a way (with no guides, instructions, or templates) so that the door mortise catches in a very narrow window. Too low or to one side, and the latch will retreat into itself without fully extending (unless you slide the door at the half locked position), too high and there is no point.The keyed portion of the latch must be aligned and tested separately, as the metal rotates independently of the cylinder. And if it is not lined up properly, the key will not be able to lock the door or be pulled out of the lock when in place.In order to combine the two pieces, you can use the screws that pass through the door. But to ensure you get the screws into the correct receiving hole....you have to pull the other handle away from the door enough to see that it will line up but not so far as to pull the metal tab/latch out on the key side. See note above on the key going out of alignment. Good luck.Finally, how does this have a 4 star review?? This product is getting complaints and reviews with 3s and 4s, but the attached reviews are horrible. People need to knock down their star count to match what they're saying, and maybe the overall product star count would match what their experience was.

Didn’t work for our door, wasn’t long enough, but if you get the proper size for your door it’s easy to install & looks nice.

Fits perfectly

Well designed. No issues with installation.
