The Best Keyless Door Locks on Amazon, According to Hyperenthusiastic Reviewers

Over 4,000 reviewers give this smart lock a five-star rating, with about 10 percent of them describing it as “secure.” One woman wanted to make sure her ex could no longer have unfettered access to her house once he moved out, so she installed this on her front door. “It’s super easy to program your own 4-digit code, and just as simple to remove a code you’ve programmed,” she writes, adding, “I find this especially helpful for when the ex needs to come pick up the kids. I can program a temporary code for him, then delete it after he’s got the kids.” Another reviewer bought this lock back in 2015, calling it “heavy-duty and nice looking.” She projected that the “battery won’t drain so fast” because of the manual lock feature, and in 2019, she updated her reviewer, since she “did finally have to replace the ORIGINAL batteries in the deadbolt,” but she notes, “I think four years is an excellent battery life.”

One once-skeptical reviewer “was hesitant to go with an Amazon branded lock versus one of the established, big vendors,” but reports, “It worked out great. The lock looks even better in-person, took less than 10 minutes to install, and works flawlessly.” Another ponders, “Where have you been all my life?” He explains, “I can’t tell you how many times I was working in my shop only to come around to the front door and find that my kids left and locked me out of the house. Then there’s the times when you’re in your car and you have to go back in the house because you forgot something. All those things are no longer a problem.” This lock also has a customizable auto-lock. Customers can choose between 10 and 99 seconds how long they want the lock to wait before auto-locking. And reviewers seem to love that. One reviewer says it’s “easy to program the auto re-lock” and he plans to buy more for his store.

“I know it’s silly, but this door knob has been a life changer,” writes one reviewer who thinks it’s “wonderful to not have to worry about keys anymore.” They say it’s easy-to-install and love that it locks automatically, but the built-in LED light takes it over the top. “The LED light is bright and illuminates the key pad and beyond.” One more reviewer enjoys how sensitive the keypad is compared to others he’s tried in the past. “Often my hands are full with bags so I end up using my pinky finger or knuckle to hit the buttons and it works just fine,” he writes. He also notes that a delightful perk is that “you can push the handle down or up to open the door.” Another loves that this lock actually has more memory than most, since it “allows for up to 19 different 4-number codes to be programmed into the memory.” And according to him, “Programming is very easy.”

Like most keyless locks on this list, this one is described by many as easy-to-install and easy-to-use. But one feature that gets cited often by five-star reviewers is the auto-lock functionality. “If someone (the kids), comes in or leave and forgets to lock the door, it will auto lock after 30 seconds,” one reviewer explains. Some question how long the battery will last since auto-lock features tend to wear it down. But one reviewer confirms, “I’ve had this installed for about 6 months now on my primary door to my house.I lock and unlock it multiple times a day. It’s still on the first set of batteries.” Another who has installed six of these in her house appreciates that they all take “the same key so you only have to pack one key for all of them and the only reason you need a key is if you let the battery die.” She says in four years she has never “had a problem with any of them.”

Reviewers who have had issues with dying batteries in their keypad locks appreciate that this one has no motor or auto-lock feature, which “greatly increased battery life,” according to one reviewer. “If you’re on the fence about automated locks, this one has a MANUAL deadbolt engagement. No burned out motors or worries of misaligned doors. You enter the code, the latch releases, and you turn the lever to lock/unlock,” explains one reviewer. Another perk of this keyless lock, especially for those in extreme weather: “If you’re in a cold climate, a battery powered deadbolt will slow or not work as well in colder weather. You don’t have to worry about that issue with this lock since it is fully manually operated.” And many reviewers update their reviews to share just how long the battery can last. “I have now been using this lock daily for over two years and have yet to replace the batteries. It works just as well now as it did the day I installed it,” one reviewer writes.

“Flex-lock” means that customers can set this keyless door lock to either auto-lock or manually, and it’s so useful, one reviewer writes, “I should have done it years ago.” They explain, “I’ve always disliked having to use a house key after parking in the garage. So we used to leave it unlocked, which defeats the purpose of having a lockable door. Now our door remains locked when closed, but a quick turn of the flex lock when going to the garage for a minute allows normal re-entry.” Many reviewers with with kids and lots of family members agree that the flex-lock makes coming and going so much simpler. One household often throws parties with lots of family. Making sure everyone has the code to get back inside can be tedious, so they bought this lock. The dad explains, “Having the flex-lock option to leave it unlocked is also important for us, especially on party days when many people come and go constantly.”

After reading horror stories reviewers wrote about being locked out due to forgetting to change the batteries in their keyless locks, customers chose this Lockey lock because it requires no batteries at all. One reviewer credits her first lock lasting ten years to the fact that it has “no batteries, it’s purely mechanical.” She adds that even after a decade of use, “it is still functional, just worn out from the weather.” Another says if you’re concerned about the lock wearing out due to weather, he oils “the interior mechanism” once a year. He owns five of these that are over 10-years-old and says they’ve held up nicely. One mom overall just feels more secure with this lock even though it’s easy enough for her toddlers to use it. “It’s perfect, secure and barely noticeable on our black frame/glass front door. It does want we need, intimidate people looking to get in and is operator-friendly enough for the kids to unlock the door without a key for mommy when her hands are full.”

“I am so thrilled to have this lock,” writes one reviewer. “No more kids losing or forgetting their keys. No more logistics of getting a key to the pet sitter. If someone needs emergency access when we are not around, we can just give them the code - and then delete or change it later.” And many more agree that this keyless lock is particularly convenient, thanks to features like an alarm that goes off if the lock isn’t fully engaged and built-in backlight for the keypad. But in case they do need to use a key, Kwikset invented the Smartkey, which allows every door in one house to unlock with the same key. “It saves you from having to match keys on multiple doors at the store. Plus you don’t have to give out new keys to your family when you install new locks,” one reviewer notes. Another also calls it “handy” and likes that they only need “one key than can open all doors,” so it takes away having to carry a full key-ring for one house. For them an additional perk is that they have “The ability to lock the door on the way out with one button,” which saves a lot of time.
