Smart locks are genuinely good hardware, and we fit a lot of them across King City, Maple and Kleinburg. They also fail in three specific ways in a York Region winter, and all three are avoidable if you know about them before January.
One: the batteries die faster than you think
Alkaline batteries lose a substantial share of their usable capacity below freezing. A set that would comfortably last a year on an interior door can drop to a few months on an exterior door exposed to wind and a north face.
Worse, the failure is not gradual in the way people expect. The lock warns you at a state of charge that assumes room temperature, and then a cold snap arrives and the remaining margin disappears in a day.
Two habits fix this permanently. Change the batteries every autumn whether or not the lock has asked, and use lithium cells rather than alkaline on exterior doors — they hold their voltage far better in the cold. Keep a spare set inside the house, not in the garage.
Almost every smart lock call we get in January is a battery that was replaced last January and was never going to survive a second winter.
Two: the previous owner still owns the lock
This is the one that surprises people. A smart lock is administered through an account, and that account belongs to whoever set it up. Buy a house with a smart lock already on the door and, unless somebody deliberately handed it over, the seller still has administrator access.
That means they can potentially add codes, remove yours, and in some cases see when the door was opened. Changing the code you use does nothing about it, because the code is not where the control lives.
The fix is a factory reset followed by a fresh setup under your own account — not just a new code. Do it in your first week, alongside rekeying the mechanical locks on the rest of the house. If the seller left no documentation and the lock will not reset, we can usually get it done, and where we cannot, replacing the lock is the honest answer.
Three: the door, not the lock
A motorised deadbolt has to push its bolt into the strike using a small motor. A person with a key has leverage and can force a slightly misaligned bolt through with a shove. A motor cannot, and it will not tell you that is the problem — it will simply report a jam, retract, and try again until the batteries are flat.
This is why smart locks are unusually sensitive to exactly the seasonal frame movement that every wooden door in Ontario goes through. A door that a person could lock all winter by leaning on it slightly is a door a motor will fail on.
So the correct sequence when fitting a smart lock is: align the door first, then fit the lock. Strike positioned properly, bolt dropping cleanly with no resistance, screws long enough to reach the stud. Ten minutes of alignment prevents an entire winter of jam errors.
What smart locks are genuinely good at
- No key to be locked away from. The single most common lockout — the door that latched while you stepped outside — largely stops happening.
- Codes you can give and take back. A cleaner, a dog walker, a contractor, a house guest. Issue a code, remove it afterwards, no key ever leaves your control.
- A record of who came in. Not surveillance — just the ability to answer the question later.
- Remote checking. Being able to confirm from the car that the door is locked is worth more in daily peace of mind than most security hardware.
What they are not is a replacement for a good door. A smart lock on a frame held together by three-quarter-inch screws is a clever electronic system protecting a piece of trim. Fit the long screws and the reinforced strike first; the lock is the last part, not the first.
