High security locks are cylinders and deadbolts designed to defeat the methods used against ordinary doors. Inside the cylinder a second locking mechanism, usually a sidebar released by finger pins or rotating pins, has to be satisfied at the same time as the normal pin stack, which is what stops picking and bumping. Hardened steel inserts stop drill bits. The bolt is thicker and carries a hardened pin against sawing, and a reinforced strike ties the lock into the wall framing. Just as important, the key is cut on a patented blank that only an authorised person can have copied, so your key count stays known.
How the visit goesYour shop has had four employees leave in two years and each one had a key. Rekeying every time is getting old, and the hardware store will cut a copy for anyone who walks in with the original.

How the visit goes

- 1
What the door is protecting
The assessment starts with a question rather than a tape measure: what is behind this door, and what has made you think about it now? A front door on a family home, a stockroom with prescription drugs and a server closet in an office carry different risks and deserve different levels of hardware. The locksmith also asks who has keys today and how sure you are of that count. Those answers decide whether the right answer is a graded deadbolt with a controlled key, a laboratory-rated cylinder in a heavy lock body, or a small keyed system across several doors. Spending goes where the risk actually sits.

Reinforcing the strike and frame
The strike is where a forced door actually fails, so it gets serious attention. The stamped plate comes off and the pocket is deepened to accept a box strike or a long reinforced strike, fastened with three-inch screws that pass through the jamb into the wall framing. Stripped or split wood is filled and doweled first so the screws have something to hold. Where the frame is thin, a wrap-around reinforcer around the door edge and a full-length jamb plate are options. The result is a bolt that ties the door into the house rather than into a strip of trim.

A door that shuts like a vault door, quietly
With a heavy bolt, a deep strike and long screws in the frame, the door feels different when you lock it: the bolt travels its full length and seats with a solid, quiet stop. That feel is your ongoing check. If the bolt ever starts to drag or you need to lift the door to lock it, the door or hinges have moved with the seasons and a small adjustment restores it. Wood doors swell in humid summers and shrink in dry winters; a glance at the hinge screws and the strike each spring and autumn keeps everything aligned.

What affects the quote
- 1
Distance and access
A rural property, a high-rise with loading dock rules or a site that must be visited outside trading hours affects travel and scheduling, and the quote says so plainly.
- 2
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.
- 3
Cylinder rating and format
A patented residential cylinder, a laboratory-rated commercial cylinder and an interchangeable core sit at different points on the scale, and the format that fits your present hardware decides which lines are available.

High Security Locks: questions
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 about the glass panel next to my front door?
A sidelight within reach of the inside thumb-turn is the weak point of an otherwise strong door, since a broken pane lets a hand reach the turn. Options include moving the deadbolt further from the glass, a lock function that needs a key inside as well, or a laminated pane. Because everyone must still be able to leave easily, the locksmith talks through the trade-offs and helps you pick the arrangement that suits your household.
How long does the installation take?
A cylinder swap with new keys on one door is a short visit. A new deadbolt, reinforced strike and frame repair takes longer, and several doors keyed to a plan take longer again, mostly in bench time pinning cylinders. The locksmith gives you a realistic estimate once the doors have been looked at, because the frame condition and the door preparation matter more than the count of locks alone.

What the census means at the door
58%
Older homes. About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.
In neighbourhoods of established homes, keys have often been copied many times over many owners. Rekeying every exterior door to one fresh key is the common first job, and it works on old cylinders just as well as on new ones.
23%
Single-detached houses make up about 23% of homes in Toronto (2021 Census).
Where most homes are apartments or condos, storage lockers, bike rooms and parking gates carry their own locks. A locksmith can supply and key padlocks and cam locks for those spaces so one household ring covers everything it uses.
