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)

Fit perfectly in my sliding patio door. Old lock would fail to lock properly and was insecure. Also, it could not be opened or locked from the outside. This one has a lock with a regular house type key.Easy to install. But after moving and changing locks quite a few times, I still cannot understand why the bolts that go thru the door are so hard to install. They have thread all the way to the end, and it is very hard to line them up with threaded hole in the other side, which you cannot see, and cannot feel with the square end of the boltAll it takes is a little shoulder on the end of the bolt, so you can feel when it is properly lined up with the threaded hole.Manufacturers take notice!!!

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.

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.

The installation was pretty straightforward and basic tools only are needed. Just be careful inserting the inner core so it doesn’t slide to bottom of door. I had to use a strong magnet to retrieve it from the bottom of the frame as it slid to the bottom when I inserted it to install outer components. Once secured, it was a breeze to finish the installation. Now it locks securely and easily with the two keys supplied. A good investment in security.

I bought this hoping to quickly install it. The parts did fit the standard setup I had, but the inside latch engineering caused it to hang up and stick on the underside of the handle when I tried to use the key to lock the door. I ended up having to use my own washers on either side of the latch to keep it from catching on the molded metal underneath the handle. In addition, you can’t tighten the handle enough without jamming the key turning from the outside, so there is a slight movement in the handle because the outside key function will be too difficult. I should have done more homework on this. I got it done, but I had to write this review to warn others about the sticking and catching of the latch among other issues…oh yeah, almost forgot. I had to use serious cutting tools to trim the inside latch arm that extends into the mortise lock. Seemed like overkill for such a thing…move on from this product and find one thought through and manufactured better
