Are you planning to upgrade your home security or have just moved into a new place? It’s important to understand the true cost of changing door locks as the first step. In 2025, prices for a professional residential locksmith service in Canada can vary widely, based on the type of locks or a high-tech smart lock installation. Let’s break down all the factors that affect what you’ll pay, plus some tips to save money.
The Main Costs of Changing Door Locks
The final cost of changing door locks is made up of two main financial parts: the cost of the lock hardware itself, and the cost of the labor. Let’s explore these and some additional costs:
1. Locksmith Labour and Service Call Fees
Residential or commercial locksmiths charge a mandatory service call fee just to travel to your location. It falls between $70 and $90 in major Canadian cities. If the job is complicated or requires custom drilling, you will also pay an hourly labour rate of $80 to $150 per hour.
2. Hardware Price
A basic residential deadbolt typically costs around $55 to $60 CAD. A simple doorknob lock set, suitable for an interior door, might cost as little as $20 to $53. High-security mechanical deadbolts can cost between $194 and $475. Smart lock hardware often starts at around $170 to $280.

3. Installation Fee Based on the Type of Locks

| Service Type | Estimated Cost Range (CAD) Per Lock | Details |
| Rekeying (Residential) | $40 – $120 | Price for changing internal pins; often excludes locksmith service fee. |
| Basic Lock Replacement | $100 – $250 | Includes standard knob/deadbolt hardware and installation labor. |

FAQ
Is it cheaper to rekey or replace my locks?
Rekeying ($40 to $120 per lock) is almost always cheaper than full lock replacement ($100 to $400 or more per lock).
How long does a professional lock replacement take?
A standard lock replacement takes about 30 to 60 minutes, based on the lock type and the condition of the door. If the locksmith needs to drill a completely new hole for a deadbolt or install complex high-security or smart locks, the job might take longer.
What is a service call fee, and do I have to pay it?
A service call fee is the mandatory fee required just for the locksmith to travel to your location and begin the work. You must pay this fee unless you choose to remove the lock yourself and take it to the locksmith’s retail shop.
What should I check right after a new lock is installed?
Check that the key turns smoothly and locks and unlocks the mechanism when the door is open. Close the door and ensure the latch and deadbolt align perfectly with the strike plate in the door frame. Also, the door should not budge when the lock is fully engaged.
