Smart Lock Installation
You have just taken possession of the house and the previous owners handed over a keypad deadbolt with a code nobody wrote down and an app account you cannot get into.
In plain words
A smart lock that came with the house is a special case, and a locksmith treats it as a fresh installation. The device is reset to factory state following the maker's procedure, which clears codes, paired phones and schedules, and then re-enrolled under an account you create. Any hub, voice assistant or automation that had permission to open it is checked separately, because those permissions can outlive a reset on the lock itself. The mechanical override cylinder is rekeyed so the previous owner's key becomes scrap metal. Batteries are replaced, firmware is brought up to date, and the door alignment is checked as it would be for new hardware.
How the visit goesHalf the evenings someone asks whether the back door got locked, and nobody is sure. A lock that relocks on its own, shows its state in an app and reports when it was last opened would settle the question.

How the visit goes


Taking stock of an existing electronic lock
When a keypad or app lock is already on the door, the assessment is about what it knows and who it answers to. The locksmith notes the model, checks whether the keypad, motor and battery contacts are healthy, and asks whether anyone holds the administrator account, the master code or the override key. A lock the previous owner still controls from an app is not yours yet, however new it looks. If the hardware is sound, a factory reset and a fresh enrolment may be all that is needed; if the motor labours or the keypad has worn digits, replacing it is the better path. Either way the door alignment gets the same scrutiny as for a new install.
Retrofit locks that keep your outside hardware
Some smart locks mount only on the inside of the door and turn the deadbolt you already own, leaving the exterior face and the keyway as they were. Fitting one begins by checking that the existing deadbolt is on the model's compatibility list and that its tailpiece shape matches an adapter in the box. The interior thumb-turn is removed, the adapter fitted, and the motor unit clamped to the mounting plate so it sits square and turns the bolt through its full travel without slipping. Because the outside is untouched, these suit rented units where the landlord prefers the door unchanged, and older doors whose exterior hardware is worth keeping. The existing key keeps working alongside the phone.
A cleaner handover at the next turnover
For a rental or a shared home, the real payoff arrives at the next change of occupant. Instead of collecting keys and wondering about copies, you delete the departing tenant's code, add one for the incoming tenant and confirm the change in the app. The small register the locksmith helped you start shows who still has access and which codes are due to expire. Any guest, cleaner or contractor codes that belong to the old arrangement go at the same time. The override key stays under your control and is handed over or rekeyed as the tenancy rules and your own preference require, so the door changes hands with nothing left behind.

What affects the quote
Supplying the lock yourself
If you have already bought a lock, the quote covers fitting and setup only, with a note on whether the chosen model suits your door; if the locksmith supplies it, the hardware is listed alongside.
Storm door and weather adjustments
Where the entrance calls for a vented storm door panel, a keypad shield or a model rated for heat and cold exposure, those items are named separately so you can choose them or not.
Type of smart lock chosen
A keypad deadbolt, a Bluetooth model, a Wi-Fi model with a built-in radio or a lock that joins a home hub each sit at a different point on the hardware side of the quote, before any labour is counted.
What to have ready
- Is there already a keypad or app lock on the door, and who set it up?
- Do you already have a specific lock in mind or in hand?
- Do you own the home, rent it, or manage it for others?
Smart Lock Installation: questions
QuestionsThe house came with a smart lock. Can you make it mine?
Yes, and it is treated as a fresh installation rather than a hand-me-down. The lock is reset to factory settings using the maker's procedure, which wipes codes, schedules and paired phones, then enrolled to an account you create. Anything else that could open it, such as a hub or a voice assistant, gets its own check, because those permissions sit outside the lock. The override cylinder is rekeyed, batteries replaced and firmware updated. If the hardware is worn, replacing it is the cleaner choice.
Fingerprint, fob, code or phone: which is worth having?
It depends on who uses the door. Codes suit everyone and need nothing in hand. Fobs or cards are a favourite for children and for anyone who finds small buttons difficult, since a tap does it. Fingerprint readers are convenient for a household of adults but can be fussy with cold, wet or gloved hands in winter, so pair them with a code. Phone control is for whoever wants alerts and remote checks. Most families end up using two of these.
I rent. Can I have a smart lock installed?
Yes, with your landlord's agreement first. Tenancy rules in this province expect a tenant to have the landlord's consent before changing a lock, and expect the landlord to have a working way in, so the sensible route is a short conversation and a note of what will be fitted. A retrofit model that mounts inside and keeps the existing exterior lock and key is often the easiest thing for a landlord to say yes to, since the door is unchanged from outside.
