Smart locks are good products sold badly. The marketing is about convenience, and the things that actually decide whether you are still happy in two years never appear on the box.
We fit these, we like them, and we also get called out to rescue them — disproportionately between December and February. Here is what to know before you buy, and what to do if you already own one.
What They Genuinely Solve
Let us be fair first, because the benefits are real:
- No keys for children to lose. A code cannot be dropped in the snow or left in a coat at a friend’s house.
- Access you can revoke instantly. A cleaner, a dog walker, a contractor — give a code, delete it the day it stops being needed. You cannot un-issue a key.
- Scheduled access. A code that only works on Tuesday afternoons is a genuinely useful thing that mechanical keys cannot do.
- You know when people come and go. Notifications when the door is opened, which for a lot of parents is the whole selling point.
Failure Mode 1: The Battery, And Why January
A motorised deadbolt draws real current every time it cycles. Cold reduces the capacity of a battery significantly — a cell that would have lasted until spring in a mild climate gives up at minus twenty.
The result is that low-battery warnings in Whitby cluster in exactly the weeks when you least want to be standing outside dealing with it. The fix is trivial and almost nobody does it: change the batteries on a schedule, twice a year, and ignore the warning entirely. Do it when the clocks change and it never becomes an event.
Rule one, before anything else: buy a lock with a mechanical key override. Without a physical key, a dead battery, a failed motor or a corrupted firmware update turns your front door into a locksmith call. With one, all of those become mildly annoying instead. This single filter eliminates a lot of the market and it should.
Failure Mode 2: The Keypad Itself In Cold
Touch-sensitive and capacitive keypads can behave unpredictably in deep cold, and they do not always cope with a gloved hand. Physical push-button keypads are less elegant and considerably more reliable in a Canadian winter.
Check the manufacturer’s rated operating temperature range before you buy, and treat the claimed lower limit as optimistic rather than conservative.
Failure Mode 3: The Cloud
A Wi-Fi lock depends on your router, your internet connection, and a manufacturer’s service continuing to exist. That last one is not hypothetical — products in this category have stopped working when a company shut a service down.
A keypad lock that stores its codes locally keeps working through an outage, a router failure and a corporate decision. If you want remote access, fine — but make sure the lock still functions completely without it.
Failure Mode 4: Nobody Owns The Admin
This is the most common problem we are called to fix, and it is not technical at all.
A house sells and the smart lock stays. The new owners have hardware they cannot administer: codes they did not set, an app tied to somebody else’s email address, and no idea who else still has access. Or an installer set it up and kept sole administrative control.
If you cannot personally add and remove users, you do not control your own front door. Most locks can be factory reset from the interior unit and re-enrolled to a new account with fresh codes — but it needs doing deliberately, not left.
Failure Mode 5: The Door Itself
The one that matters most and gets discussed least. A smart lock changes who can open your door politely. It changes nothing about who can open it rudely.
A forced entry does not defeat a cylinder or outsmart an app. It splits the jamb trim beside the lock with one kick, because a standard strike plate is held by two short screws reaching only a thin strip of wood nailed to the frame.
Fit a box strike with three-inch screws into the structural stud and long screws in the top hinge before you spend anything on electronics. It costs a fraction as much and it is the part that actually stops a break-in.
The Buying Checklist
- Does it have a mechanical key override?
- Does it work without the internet?
- What is the rated operating temperature?
- Will it fit your door — thickness, backset, and is it a multipoint or mortise door?
- Will you hold the admin account from day one?
- Is the frame reinforced yet? If not, do that first.
If You Already Have One
Three things this week: change the batteries regardless of what the app says, change the installer or factory code, and confirm you can add and remove users yourself. Then find the mechanical key and put it somewhere sensible that is not inside the house.
