Commercial Rekeying
The manager's key ring went missing somewhere between the bank and the car, and the master on it opened every door in the building. Until the cylinders are changed, whoever finds it is holding the run of the place.

Rekeying is also a chance to decide how the keys should work, not simply to change them. Most businesses settle on a small number of key groups: one key for the doors every employee uses, another for the office, cash room or server closet that only managers open, and perhaps a single master for the owner that opens everything. The locksmith maps this out on a keying chart before touching a cylinder, then pins each lock so the plan holds true on the door. Staff carry one key instead of a ring, managers carry two, and the chart tells you at a glance who can open what.

How the visit goes
- 1
The state of the cylinders and the doors
A cylinder about to be repinned is examined the way a mechanic looks over a part before rebuilding it. The plug should turn smoothly with the right key, the pins should spring back cleanly, and the face should be free of the green bloom that salt spray leaves on storefront hardware after a few winters. The locksmith also checks how the door closes: a strike that no longer lines up, a closer that slams, or a deadlatch that fails to catch will keep a freshly rekeyed door from locking properly. Most cylinders pass and are repinned; a worn or corroded one is pointed out so you can choose a replacement for that opening.

Pinning the master and change keys
When the plan includes a master, each cylinder is pinned to accept two keys: its own change key and the master above it. Thin master pins sit in the pin stacks so the plug can turn at both the change key's height and the master's; master keying can also create extra, unintended combinations, so the locksmith charts the system to keep those from lining up with someone else's key, and the manager's key opens its whole group and nothing beyond it. A well-built system leaves unused combinations in reserve, so when the business adds a door or a department next year the new cylinder joins the plan without disturbing the keys already in people's pockets.

Adding a door without starting over
The pinning records kept from the visit mean the system can grow. When the business takes the unit next door, adds a storage cage or replaces a worn lever set, the new cylinder is pinned into an unused combination on the existing chart and handed a key from the right group, and nobody already carrying a key notices anything changed. That is the value of leaving reserve combinations in a master system rather than using them all up on day one. Keep the locksmith's reference number for the system with the chart, mention it when you call, and a single new door becomes a short visit instead of a fresh plan.

What affects the quote
- 1
Distance to the premises
Travel to the site is part of the call-out, and a unit in a downtown plaza and one at the end of a rural industrial road are different trips.
- 2
Landlord and base-building coordination
Suite doors that must accept both your key and the landlord's master, or work that needs the property manager on site, add coordination the quote allows for.

Cylinders that need replacing
Where a worn, corroded or low-grade cylinder is better replaced than repinned, the new part is added for that door alone, and the locksmith points it out before the work begins.
Same fees day, night or weekend.
Commercial Rekeying: questions
We lost a master key. Does the whole building need doing?
Only the cylinders that master opened, which the keying chart identifies. If the lost key was the top master, that is every lock in the system; if it was a departmental master, it is that department's doors. Where no chart exists, the locksmith reads the cylinders first to establish what the key reached. The remaining doors, and any keys that never opened them, are left exactly as they are.
What is the difference between rekeying a business and replacing its locks?
Rekeying keeps every lock on the door and changes only the pins inside the cylinder, so a new key works and the old ones stop. Replacing swaps the hardware itself. Commercial cylinders are made to be repinned many times, so rekeying suits any lock in sound condition and leaves the levers, trim and door untouched. Replacement is chosen door by door for cylinders that are worn, corroded or too light for what they protect.
Does stamping keys 'do not duplicate' stop people copying them?
Not reliably. The stamp is a request, and any key on a standard blank can be copied by anyone with the blank and a machine. What does work is controlling the blank itself through a restricted keyway, or controlling access to the lock through interchangeable cores and a tight register. Stamping still has a place: a serial code on each key, instead of the business name, lets you track it without telling a finder where it fits.

What the census means at the door
38%
Homes of every age. About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.
In an area of varied housing ages, rekeying is the one job that fits every door. Old cylinders and new ones both take fresh pins, so a household moving into either kind of home can start with keys that nobody else holds.
37%
Single-detached houses make up about 37% of homes in Mississauga (2021 Census).
Attached housing turns over more often than detached, so rekeying between tenants or owners is a constant. Because suite doors tend to be standard, the job is usually a straightforward pin change and a fresh set of keys cut on site.
