Commercial Lock Rekey Service

A commercial lock change — swapping out entire hardware — makes sense when a lock is damaged, outdated, or being upgraded to a higher-security grade. But in the majority of access-control situations, the lock itself is perfectly sound; the problem is simply that too many unauthorized keys are in circulation. Rekeying addresses that problem directly and efficiently. A skilled technician removes the cylinder, replaces the internal pins to a new combination, and cuts fresh keys on the spot. The mortise lock body, the strike plate, the door frame — all of it stays intact, which means no drilling, no patching, and no cosmetic repairs after the fact. For commercial property managers overseeing multiple suites in buildings along Confederation Parkway or the airport corporate corridor near Pearson, this matters: rekeying a full floor of offices in a single visit is realistic; replacing every lock set on that same floor is a multi-day, high-cost undertaking.

Multi-tenant buildings present a particular challenge because landlords must balance master-key access for maintenance and emergency entry against the privacy and security of individual tenants. Our technicians are experienced in designing and implementing master-key systems that sit on top of a rekey — meaning each tenant's suite opens only with their unique key, while a single master operates every door in the building. This layered approach is common in Mississauga's growing mid-rise commercial developments and is something our team can plan, quote, and execute in a single coordinated visit.

Every commercial property type has its own rekeying demands, and our approach is tailored accordingly. Office environments — law firms, medical clinics, accounting practices, tech companies — often combine mortise lock cylinders on main entry doors with door knob locks or lever-set cylinders on interior offices and file rooms. We rekey each cylinder to the same key if a unified access system is needed, or to discrete keys where departments require separation. Retail units on Mississauga's Dundas Street corridor frequently use grade-1 deadbolts paired with a mortise lock on the storefront; we can rekey both in a single appointment so a new owner or incoming manager has clean, documented access from day one.

For multi-tenant commercial buildings, our service includes a written key-control record so the property manager knows exactly how many keys exist for each cylinder and which master series they belong to. We work with established hardware including Schlage and Kwikset cylinders, as well as higher-security restricted-keyway systems for properties that require it. Throughout all of this work, our goal is damage-free completion — we do not drill or force any hardware unless a cylinder is genuinely seized or a lock-out situation requires it as a last resort, and even then we discuss every option with the client first.

Security situations do not follow business hours. A break-in overnight on Burnhamthorpe Road, a key theft discovered on a Friday evening, or a property manager locked out of a mechanical room on a long weekend — these are exactly the scenarios where an emergency locksmith response makes the difference between a contained incident and an extended vulnerability. Maple Guard Security operates on a true 24/7 dispatch model: when you call (289) 779-3062 at 2 a.m., a live person answers and a technician is routed to your location, not a voicemail that gets returned at 9 a.m.

After-hours commercial rekeying calls are handled with the same thoroughness as daytime appointments. The technician will verify your authority over the property — this is standard practice and protects every building owner we work with — and then complete the rekey, cut new keys, and confirm that every cylinder operates correctly before closing out the job. Pricing for emergency calls reflects the time of day, travel distance within Mississauga, the number of cylinders being rekeyed, and any parts required, such as new pins or specialty keyways. We confirm an exact up-front price before any work begins, so there are no surprises on the invoice regardless of the hour.
