ULTRALOQ U-Bolt-BK Smart Lock with App Control: 5-in-1 Keyless Entry Door Lock
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.
