Lock Change Services in Montreal
Clean, guaranteed installation in a single visit.
A reliable lock is the first line of defense for your home or business. Whether you need to replace a worn-out lock, install a new deadbolt, or upgrade to a smart lock, our locksmith in Montreal does the work on-site with trusted brand-name locks.
Unlike hardware stores that sell locks without installing them, or DIY attempts that risk misalignment, a professional lock change ensures every component is properly fitted, aligned, and tested. The technician checks the play between the bolt and strike plate, adjusts the cylinder depth, and makes sure the door closes and locks perfectly. The result: a lock that works smoothly from the first turn and will last for years.

When Should You Change or Install a Lock?
Many homeowners and tenants put off changing a lock until something goes wrong. But a failing lock doesn't warn you — it jams or gives out at the worst possible moment. Here are the signs it's time to act:
- Key catches or turns with difficulty — a worn cylinder can jam completely at any time, leaving you locked out or unable to secure your door.
- You've just moved in — the previous owner, former tenant, or real estate agent may still have key copies. A full lock change is the only way to guarantee you're the sole keyholder.
- Your lock is over 10 years old — aging locks lose mechanical strength. Picking and bumping techniques evolve, and an old lock may be vulnerable to modern intrusion methods.
- After a break-in attempt — even if the lock seems to work, the internal mechanism may be compromised. Immediate replacement is recommended to restore security.
- You want a higher-performing lock — upgrading from a knob lock to a grade 1 deadbolt or a smart lock with code access is a long-term investment in property protection.

How a Lock Change Works
The process is fast and hassle-free. The technician arrives with a full lock inventory, does the work on-site, and hands you the new keys before leaving.
Phone assessment
Tell us about your door and current lock. Our advisor identifies the right product, confirms the price, and schedules the visit — often the same day.
Removal of the old lock
The technician cleanly removes the existing lock while inspecting the door and frame to ensure there's no structural damage to address before installation.
New lock installation
The new lock is installed with precision: bolt-to-strike alignment, cylinder depth adjustment, door gap verification. If boring is needed (for a new deadbolt, for example), it's done with professional templates.
Testing and key handover
The technician tests the lock multiple times in front of you — locking, unlocking, smooth key turns. You receive all your new keys and maintenance recommendations.
New lock. New keys. Security guaranteed. Call now.
Types of Locks We Install
Deadbolts
A deadbolt is the most effective lock for an entry door. Unlike a spring latch that can be bypassed with a credit card, a deadbolt anchors firmly into the frame and resists forced entry. Our deadbolt installation service includes boring, mounting, and full alignment, with grade 1 or 2 products based on your needs.
Smart Locks
Smart locks let you lock and unlock your door remotely, by numeric code, or via a mobile app. They're ideal for Airbnb hosts, families who want to give temporary codes to kids or neighbors, and anyone who regularly misplaces their keys. Our smart lock installation service includes full device setup and configuration.
Standard Replacement Locks
For a simple, efficient lock replacement, we use Schlage, Weiser, or Yale cylinders that fit existing bore dimensions. The technician removes the old lock and installs the new one in minutes, with no modifications to the door.
High-Security Locks
For maximum protection, Mul-T-Lock and Medeco high-security locks offer patented non-duplicable keys and certified resistance to picking, bumping, and drilling. These locks are especially recommended for street-facing doors, accessible basements, and demanding commercial applications.
