Smart Lock Installation on Existing Doors in Toronto (2026 Guide)

We install smart locks every week, and the lock itself is rarely the hard part. What decides whether the job takes forty minutes or half a day is the door: the size of the holes, the distance from the edge, the thickness of the slab and, most of all, whether the deadbolt slides into the frame without any pushing or lifting. A smart lock motor is much weaker than your hand. If you have to pull the door toward you to turn the key today, a motorized deadbolt will jam, drain its batteries and eventually stop working.

That is why a good installation starts with the door, not the box. We check the frame and strike, the hinges and the gaps. Often a small adjustment to the strike plate or a longer hinge screw is all it takes. Sometimes the door has sagged enough that it needs proper realignment first.

This guide covers the main types of smart locks, the measurements that matter, the extra rules for condo and apartment doors in Toronto, what our winters do to batteries and keypads, and how to keep a smart lock secure. If you already have a lock in hand, send us the model and a photo of your door edge, and we will tell you if it fits.

For most Toronto homes we suggest starting with what you actually need. If the goal is letting a cleaner, a dog walker or family members in without handing out keys, a good keypad deadbolt does the job with the least fuss. If you travel, run a short-term rental or want to know when the kids get home, a connected lock is worth the extra setup. For small offices with several staff, a proper access control system is usually a better long-term choice than consumer smart locks, because it keeps a reliable log and survives heavy daily use.

In most condominiums the suite entry door is part of the building's fire separation, and changes to it are controlled by the condo corporation. The door usually has to stay self-closing and self-latching, and the corporation may require that the hardware matches the rest of the corridor. Many buildings also need a key or code for emergency access. Before you install anything, check your declaration and rules, and ask management. Our condo door replacement rules guide explains the usual requirements, and our fire-rated door code guide covers why rated doors cannot be modified freely.

For tenants, a retrofit smart lock that only replaces the inside thumb-turn is often the easiest option, because it keeps the landlord's key working and can be removed when you move out. It is still a change to the lock, so get permission first.

For landlords with several units, keypad locks make key handovers much simpler. Codes can be changed between tenants without a lock change. For small buildings with a shared entrance, the lobby door is a different job: it usually needs an electric strike or access control rather than a consumer smart lock.
