Are smart locks safe? An honest locksmith's view

Keyless entry is convenient and genuinely useful for some homes — but it isn't magic. Here's where smart locks shine and where they don't.

Smart locks have gone from gadget to genuinely useful, and we fit a fair few now. But "smart" doesn't automatically mean "more secure". Like any lock, a good one fitted well is excellent, and a cheap one fitted badly is a weak point. Here's the honest picture.

What smart locks are genuinely good at

  • No keys to lose. Codes, fobs or your phone instead of a key that can be copied or left in a pocket.
  • Access you control. Give a cleaner, dog-walker or holiday-let guest a code that you switch off afterwards — no cutting keys, no chasing them up.
  • A record of who came and went. Useful for households, lets and small businesses.
  • No more "did I lock it?" Many auto-lock behind you and let you check from your phone.

Where people get caught out

The lock is only as strong as the door and frame it's fitted to — a brilliant smart lock on a flimsy door is still a flimsy door. Cheap models can have weak physical mechanisms behind the clever electronics. Batteries go flat (good ones warn you well in advance, and most have a key or power backup). And anything app-connected needs sensible passwords and updates, just like your phone.

Smart, or just a good traditional lock?

For a lot of homes, a quality British Standard cylinder or mortice lock is still the right answer — simple, insurance-friendly and nothing to charge. Smart locks earn their place where convenience and access control genuinely matter: busy families, shared access, lettings, Airbnbs. Often the best setup is a strong physical lock with smart convenience on top, not one instead of the other.

We fit and advise on keypad, fob and app-controlled locks alongside traditional ones — see digital & smart locks, or talk it through with us before you buy.

— Common questions

FAQs.

Will a smart lock work with my insurance?
Check your policy wording — many insurers still want a British Standard lock on the final exit door. We can fit a smart lock that keeps a BS-rated mechanism so you stay covered. Always confirm with your insurer.
What happens if the battery dies?
Good smart locks warn you for weeks beforehand and include a physical key override or an external power contact, so a flat battery never locks you out.
Can smart locks be hacked?
Reputable brands use strong encryption, and in practice a burglar is far more likely to try a weak door than hack a lock. Stick to trusted models, use sensible codes and keep firmware updated.
