I installed this on my redwood gate.There have been reports from my area of thieves going into backyards and breaking in through the sliding glass door. An unlocked gate makes this much easier. A locked gate can’t stop a really determined thief, but it makes it somewhat harder.The key for me (pun) was being able to match this to my existing house key! The Smartkey system allowed that.Install was straightforward. I think it’s important to add extra strength if you have a wood gate. Ideally a 2x4. I used an extra fence board I had around instead as redwood 2x4s are pricier right now.The lock works well from both sides and the spring seems reliable.It’s not Fort Knox but it will hopefully make a thief move on.I’m tempted to try to install one of these on my roll up garage door as I don’t care for the handle lock on there now. It might work but I need to investigate more to see if it will properly.Here is my install process1. First I put a second fence board in back of the last pice to thicken the area. So basically two 7/8” thick boards.2. Determined the best place for the lock. About mid way.3. Reversed the lock from right hand to left hand. Which was really easy.4. Drilled a pilot hole than a 1.5 saw drill hole.5. Installed lock.6. Installed latch lock on inside gate post.7. Rekeyed to match my home key.Done

After a little bit of a fight with the gate (it was a bit wonky and needed planing flat) this lock was no harder to fit than any other. It transformed how useful our side gate is. Before, I had to come through the house to unbolt it, so we only used the gate when we had to. Now, we can use it as a second secure entrance.

I really like this lock. The lock side is solid metal and compact, and the latch slides easily with good feedback. It's also quite simple to change handedness, and make compatible with other Kwikset (and even Schlage, see below) keys to match the rest of your house, if desired. I took one star off because I wished that the latch body were metal instead of plastic, that the slider were a bit more finished in appearance and function to lock it, and that there was a way to lockout the slider to prevent it from opening (i.e., with a padlock hole or similar).There are a lot of other reviews about issues with the lock mechanism, the springs and/or the latch. Fortunately I've had none of these happen to me, and you can avoid them if you do some testing before installing:1) Try the key to make sure it works. Seems simple, but Kwikset SmartKeys are notorious for having key issues. There is a way to reset the tumblers if your key doesn't work, but it's very complicated. If it doesn't work, or won't rekey, send it back.2) Test the latch mechanism numerous times by sliding it locked, and using the button to unlock it. If it sticks or jams, send it back. Then lock it, and try shaking and tapping it on all sides. If it unlocks inadvertently without using the button, send it back.3) Screw the lock and latch together temporarily, and try using the key to lock and unlock it repeatedly. There is more resistance while locking it, but it should still be smooth and not too stiff. If it doesn't work properly, send it back.Assuming all of the above checks work for you, prep your installation by really making sure of your gate thickness, desired height, gap between the gate and post or wall (including any protrusions or oddities), and whether you need the strike plate or loop. Use the templates and carefully follow the instructions to mount it appropriately. Then test it several times from both sides.As far as keys, it comes with a Kwikset SmartKey cylinder that is rekeyable with any compatible Kwikset key. However, there is a way to make it compatible with Schlage/Assa Abloy SC1 (5-pin) keys too. You need to separately purchase the Kwikset 85174 in black finish (it also comes in silver and gold) which is a Kwikset cylinder with an SC1 SmartKey keyway. It's about $15-20 online if you search "Kwikset 85174 black", mostly available from locksmiths. Then it's a pretty straightforward swap:1) Rekey the new cylinder to your desired Schlage SC1 key as you would a normal Kwikset key (using the rekeying tool that comes with the gate lock).2) With the lock off the gate, take the existing cylinder out of the metal body by removing the metal clip on the backside and sliding the cylinder and tailpiece out through the front of the body.3) Loosen the retaining clip on the back of the old cylinder just enough (doesn't need to come off completely) to release the tailpiece, which you'll need to move over to your new cylinder to match the needed length.4) Loosen the retaining clip on the back of the new cylinder just enough to release the tailpiece, and install the tailpiece you removed from the old cylinder. Slide the retaining clip back in.5) Slide the new cylinder back through the front of the lock, and secure again with the metal clip. You are done!I've had a full year of great use from this lock in rain, sun, snow, ice, wind and dust. It's never opened accidentally, and still works smoothly most of the time. I make sure to lubricate the slider (silicone or white lithium spray) and keyway (graphite or Teflon spray) a few times a year. It's jammed a few times after severe freezing rain, so now I make sure to pack the internal metal that operates the release lever with lithium grease in the fall and spring. Never use WD-40 (which is a degreaser, not a lubricant) unless you're cleaning it before applying a proper water-repelling lubricant. Happy locking!

I live in the Kwikset ecosystem, and this is, unfortunately, the best solution available for it. The thing has issues, but like the title says: if you need it, you need it.Weak springs in the lock retention pin. Like others, I found it relatively easy to jiggle the bar or bump the fence post enough for the pin to wiggle free. Some reviews suggest a stiffer spring, but but these seem hard to find, even at a decent hardware store, so I shortened the spring travel with a stack of washers: I used four #4 stainless steel washers, but considering the assembly it seems like nylon will work for a few cents less.Sticky unlock button: the stamped metal body is finicky, especially with changes in temperature and wood moisture, so one other modification I made was a slight bend in the lower tab so it can move more freely.This lock is relatively cheap considering the alternatives, but it will also cost you a lot of time and patience to work properly. You need to be patient, you need to be handy, and single key convenience needs to be REALLY important to outweigh the hassle.

Easy to install. Works well.

I purchased this item and fitted it to my back gate. After installation I discovered that they key supplied with the lock did not in fact fit it, requiring me to remove the lock (and leaving a large hole in the gate) and ship it back to the US for a refund several weeks later. This just shouldn't happen.

If your fence door is not perfectly aligned to fence framing you may need some handy man skills to improvise the framing. But I was very happy with end result .

Works well gets a little sticky in cold weather.
