Home Rekeying Service
Moving into a new home in Mississauga — whether it's a detached house near Lakeview, a townhouse in Erin Mills, or a condo off Hurontario Street — is one of the most important transitions you'll make. One step that often gets overlooked in the excitement of unpacking is making sure that no previous owner, contractor, or tenant still holds a working key to your front door. Our home rekeying service is the fastest, most cost-effective way to take full control of your home's security without replacing the entire lockset.

What Rekeying Actually Does to Your Locks
When a lock is rekeyed, a skilled technician disassembles the lock cylinder and replaces the internal driver pins and key pins with a new, uniquely cut set. The result is that only the newly cut key will operate that lock — every previously existing key, including builder's keys, master keys issued during construction, and any copies a former tenant may have made, becomes permanently useless. This is a fundamentally different process from changing a lock, which involves removing and replacing the entire hardware unit. Rekeying preserves your existing hardware — your deadbolt, your door knob lock, your mortise lock — while completely resetting who has access.
A mortise lock, common in older Mississauga homes and heritage properties, is one of the more complex lock types our technicians work with. Unlike a standard cylindrical deadbolt that fits into a drilled hole, a mortise lock is recessed directly into the door's edge inside a mortise pocket, giving it greater holding strength and a more refined finish. Because of that complexity, mortise lock rekeying requires experienced hands — our team carries the appropriate cylinder tools and replacement pin kits to service these locks cleanly, without damaging the lock body or the surrounding door edge.
Home Rekeying Service for New Homeowners and Rental Turnovers
New homeowners face a specific security gap that most people underestimate. During the listing and sale process, a property may have been accessed by real estate agents, home inspectors, stagers, contractors, and multiple prospective buyers — each potentially having had a key, even temporarily. Builder communities in areas like Churchill Meadows or Lisgar often use a single construction master key across dozens of units during the build phase, meaning your brand-new home could share a key profile with every tradesperson who worked on the street. Our home rekeying service closes that window completely, and because our technicians are mobile and available around the clock, you can schedule it the same day you receive possession.
For property managers and landlords, rekeying between tenants is both a practical security step and a responsible property management practice. Ontario tenants have a right to privacy and security, and demonstrating that locks have been freshly rekeyed before a new tenancy begins helps establish trust from day one. Our team can rekey every entry point in a unit — front door deadbolt, rear door knob lock, garage access door, and any interior locks — during a single visit, so the unit is ready for the incoming tenant the same day. We confirm an exact up-front price before any work begins, so there are no billing surprises when the job is complete.
Every Lock Type We Service: From Door Knob Locks to Commercial Mortise Cylinders
Our technicians are equipped to rekey, repair, or replace a comprehensive range of residential and commercial lock hardware.

Our commercial locksmith capability means we can also handle office suites, retail units, and mixed-use ground floors — useful for homeowners who operate a home-based business and need to separate access zones within the same property.
Emergency Locksmith and After-Hours Rekeying in Mississauga
Security concerns don't follow business hours. If you've just discovered that a key is missing after a break-in, a domestic dispute, or an unexplained property entry, you need an emergency locksmith response — not a next-business-day appointment. Our team operates 24 hours a day, 7 days a week, including weekends and statutory holidays. Whether it's 2 a.m. on a Tuesday or a Sunday morning during a long weekend, a real dispatcher answers the call at (289) 809-6138 and routes the nearest available technician to your location. Time of day is one of the factors that goes into your final quoted price, along with travel distance, the types and number of locks involved, and any parts required — and you will always receive that confirmed price before we start work.
Our mobile dispatch model means there is no storefront to drive to and no waiting room. The technician arrives with a fully stocked service vehicle, works at your door, and leaves with every lock rekeyed and every new key tested and confirmed in your hands. For Mississauga residents along busy corridors like Dundas Street West or the communities surrounding Cooksville GO Station, we understand that parking, condo building access, and after-hours entry logistics require a technician who communicates clearly about arrival time and building access protocol — and ours do exactly that.
Frequently asked questions
How is rekeying different from replacing a lock entirely?+
Rekeying changes only the internal pin configuration inside the lock cylinder so that old keys no longer work. The lock hardware itself — the deadbolt body, the door knob lock chassis, or the mortise lock case — stays in place. Lock replacement involves removing the entire hardware unit and installing a new one. Rekeying is the right choice when the hardware is in good working condition and your only goal is to invalidate existing keys. Replacement makes more sense when the lock itself is damaged, worn, or you want to upgrade the security grade at the same time.
How many locks can be rekeyed in a single visit, and how long does it take?+
A typical single-family home in Mississauga has two to four keyed entry points — front deadbolt, rear door, garage man-door, and sometimes a basement entry. A standard residential rekeying job for that setup usually takes between 45 minutes and an hour and a half, depending on lock types. Mortise lock cylinders take slightly longer than standard deadbolts due to their more complex disassembly. Our technician arrives with a full range of pin kits and tools, so there is no delay caused by missing parts. We can also key all your locks alike during the same visit so a single key operates every entry point.
What factors determine the final price of a home rekeying job?+
Several variables go into the final quote: the number and type of locks involved (a door knob lock and a standard deadbolt take less time than a commercial-grade mortise lock), the time of day the work is performed, travel distance to your location in Mississauga, and whether any replacement parts such as new cylinders or additional keys are needed. We confirm the exact price with you before any work begins, so you are never presented with a surprise invoice after the job is done.
Do I need to be present during the rekeying, and what ID do I need to show?+
Yes, you or an authorized representative must be present during the service. Our trained technicians follow a standard ownership verification process — we will ask to see proof of residence or ownership such as a government-issued ID showing the property address, a utility bill, a lease agreement, or a recent mortgage document. This step protects you as much as it protects us; it ensures that no one can request a rekey on your property without your knowledge. This is a standard practice on every residential and commercial locksmith call we perform.
Can you rekey a mortise lock, and is it harder than a regular deadbolt?+
Yes, we rekey mortise locks regularly. A mortise lock is more involved than a standard cylindrical deadbolt because the cylinder must be carefully extracted from within the lock body, which is recessed into the door. It requires specific removal tools and the correct replacement pin kit for the cylinder profile. Our technicians carry equipment for both residential and commercial-grade mortise lock cylinders, so regardless of whether your Mississauga property has a traditional mortise set on an older door or a newer high-security commercial mortise unit, we can service it cleanly and without damaging the surrounding hardware.
How quickly can a technician reach me for an emergency rekeying in Mississauga?+
Because we operate as a fully mobile team dispatched from within the Mississauga area, our estimated arrival times are based on real-time technician location rather than a fixed storefront address. When you call (289) 809-6138, the dispatcher will give you an honest estimated arrival window based on where the nearest technician currently is. We are available every hour of every day, including statutory holidays — our emergency locksmith service is not limited to business hours. If you are in a time-sensitive situation such as a suspected unauthorized entry, we treat that as a priority dispatch.
