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.
