High Security Locks
You jiggle the key a little and the old deadbolt opens even when the cut does not look quite right. If your worn key can do that, you wonder what a stranger with the right tools could do.

For a business, high security locks are as much about paperwork as metal. A restricted or patented key system registers the premises with the locksmith, names who may order keys, and numbers every key cut. That is what turns a lost staff key from a mystery into a line in a log. The hardware backs it up: cylinders with sidebars and hardened inserts, heavy-duty deadbolts or mortise locks, and strikes set into the structure. Where several doors are involved the keys can be arranged so a manager carries one key and staff carry keys that open only their own areas.
How the visit goesA colleague showed you a video of a lock being opened with a bump key in a few seconds. Then you went home and noticed your own deadbolt is the same style, bought at a hardware store a decade ago.

How the visit goes

- 1
Winter, weather and daily use
A door on a farmhouse porch, a condo corridor and a shop on a busy street each see different wear. The locksmith asks how the door behaves in cold weather, whether the key has ever frozen or stuck, how many times a day it is used and whether it slams behind people. High-security cylinders with sidebars and telescopic pins are precise mechanisms and appreciate a door that closes true and a keyway kept clean. The recommendation may include a weather cover for an exposed cylinder, a closer adjustment or a hinge repair so the new hardware lives a long life.

Heavy hardware for commercial doors
Storefront, warehouse and office doors take heavy-duty lock bodies rather than residential deadbolts. Depending on the door, that means a commercial deadbolt or mortise lock with a hardened cylinder guard, a free-spinning collar that defeats wrenches, and a laboratory-rated cylinder inside it. Narrow aluminium doors get a deadlock made for their stile. The locksmith fits the lock to the existing preparation where it is standard, adjusts the strike in the frame, and confirms that any exit device or closer on the same door still works exactly as before so people leave easily while the door holds from outside.

Proof for insurers, landlords and tenants
You leave with a written record of what was fitted: the cylinder type and its rating, the deadbolt grade, the strike and screws installed, and the key system registration. Insurers sometimes ask for this when a policy specifies stronger hardware, landlords keep it in the property file, and tenants have something to hand back at move-out. It also helps the next locksmith, who can see at a glance what keyway and format the doors carry. Keep the invoice and the key control documents together; they are the paperwork side of a physical upgrade.

What affects the quote
- 1
Exit devices and closers on the same door
Where a commercial door carries a push bar or closer, the new lock must work with them, and adjusting or replacing that hardware is part of the same visit.
- 2
Cylinder only or full deadbolt
Swapping the cylinder inside a sound deadbolt is a smaller job than fitting a new graded deadbolt through the door, and a knob-only door that needs a fresh bore is bigger again.

Master keying
Arranging staff keys, area keys and a manager key on one system takes bench time to plan and pin, and the more levels you want, the more careful that planning is.
Same fees day, night or weekend.
High Security Locks: questions
Can all my doors be on one key?
Yes, and most homes ask for exactly that. Every exterior cylinder is pinned to the same combination so one controlled key opens the front, back, side and garage entry. A gate or shed padlock on the same keyway can join it. For businesses, the same keyway can carry a small master system where staff keys open only their areas and a manager key opens everything. The keying plan is agreed before any pinning is done.
What is the difference between restricted and patented keys?
A restricted keyway is one the manufacturer supplies to a limited set of dealers, so blanks are harder to obtain but not legally protected. A patented key design is protected by a patent for a fixed term, and making or selling the blank without permission is unlawful during that time. Patented systems give the firmer control; restricted ones give a useful step up. The locksmith explains which your chosen line uses and when any patent expires.
What proof do I need to show before locks are changed?
The locksmith confirms that the person ordering the work is entitled to change the locks: the owner, a tenant with the landlord's agreement, or a property or facilities manager for a business. Photo identification and something linking you to the address usually settle it, and for a company a letter or a call to the named contact does the same. It protects you as much as anyone, since the same check stops someone else from changing your locks.

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 neighbourhoods with a mix of older and newer homes, the finishes on the doors vary widely: aged brass, satin nickel, matte black. A locksmith serving such an area keeps a range of finishes so replacement hardware suits each house.
37%
Single-detached houses make up about 37% of homes in Mississauga (2021 Census).
Where housing is mostly apartments and condos, mailbox locks are a regular call. A worn or lost mailbox key is a small job that a locksmith handles alongside the suite door, and the new lock comes with fresh keys cut on the spot.
