ULTRALOQ U-Bolt-BK Smart Lock with App Control: 5-in-1 Keyless Entry Door Lock
Meet the ULTRALOQ U-Bolt Smart Lock—your new best friend in home security. This isn't just any lock; it's a 5-in-1 keyless entry powerhouse that laughs in the face of traditional keys. With features like an anti-peep keypad (because who likes nosy neighbors?), smartphone app control, auto unlock, and even a shake to open function (for when your hands are full of groceries), it's like having a personal doorman. Plus, it plays nice with Apple Watch and, just in case, comes with a mechanical key for those "I forgot my phone" moments. Perfect for residential and commercial spaces, it boasts ANSI Grade 1 security because safety shouldn't be an afterthought.
But wait, there's more (and no, this isn't an infomercial):
- App Control: Lock, unlock, and play gatekeeper from anywhere—because sometimes you just wanna let the cat sitter in without getting off the couch.
- Auto Lock/Unlock: It locks itself after a while (no more paranoid double-checking) and welcomes you home like a loyal pet.
- Voice Control: Alexa and Google Assistant compatible, so you can boss it around with your voice. "Open sesame" optional.
- DIY Installation: Fits most US standard doors without turning your weekend into a drilling marathon.
And with an IP65 rating, it's as unfazed by dust and weather as a cat is by your problems. Rain or shine, it's got your back.

Smart Lock with App Control
Charles Y.

As a freelancer working from home in Boston, this lock has been a game-changer for my daily routine. I got it a couple months back and it's held up great through all sorts of weather—rain, snow, you name it. I love how it integrates with my smart home setup; being able to control it with my voice or phone makes life so much simpler, especially when my hands are full with groceries or I'm deep in a work project. The security feels top-notch, and the DIY install was a breeze, saving me time and money. It's not perfect—the occasional lag with auto-unlock can be annoying, and the keypad visibility could be better—but overall, it's an incredibly reliable and helpful addition to my home. Highly recommend for anyone looking to upgrade their security without the hassle.
- Pros: Incredibly easy to install myself in under an hour with basic tools, no pro needed. The app lets me lock or unlock from anywhere, which is a lifesaver for letting in guests or deliveries when I'm out. It automatically locks after a bit, so I never worry about forgetting, and it welcomes me home smoothly when I approach. Voice commands work well with my assistant, adding a fun hands-free option. The build feels solid and handles rain and dust without a hitch, keeping my home secure.
- Cons: Sometimes the auto-unlock feature seems a bit slow to recognize me, leading to a brief wait at the door. The keypad can be tricky in direct sunlight, making it hard to see the numbers clearly. Battery life seems decent but requires monitoring, as it drains faster with heavy app use. The mechanical key backup is handy, but I wish it was a bit more discreet or easier to access in emergencies.
