7MD Smart Door Lock Review: Advanced Security and Smart Control via Mobile
You're halfway to the office when the question pops into your head: did I lock the front door? This unsettling feeling, so familiar to every homeowner, leaves you in a quandary. Do you turn back?
Peace of mind, on your phone
The 'did I lock the door?' spiral is exactly the problem a smart lock solves: open the app, see the state of your door, lock it from wherever you are. For households with cleaners, deliveries or relatives coming and going, temporary PIN codes replace the spare-key shuffle entirely.
What to look for in a smart lock
Entry methods are the big differentiator — look for a lock that layers several: fingerprint, PIN pad, app and a physical key backup. The key backup matters more than it sounds; batteries die, phones get lost, and you still need to get in. On that note, check how the lock warns you about low battery and whether it offers an emergency power option from outside.
Fit is the unglamorous part that decides everything: confirm the lock suits your door type and thickness before buying, and if you rent, check what your building allows. Our team can talk through compatibility before you commit.
The best smart lock is the one with the most ways in — fingerprint, PIN, app, and always a physical key backup.
