Most break-ins do not involve picking; they involve a boot, a pry bar or a key that should never have been copied. High security hardware answers all three. A deadbolt with a full one-inch throw and a hardened core resists sawing and kicking, a reinforced strike with three-inch screws keeps the jamb whole, and a patented keyway means a copy can only be made through the locksmith who holds your system. The pick, bump and drill resistance of the cylinder is the layer on top. The locksmith's job is to fit those layers to your particular door and your particular worries.

How the visit goes

- 1
Door, hinges and what surrounds them
The door itself is inspected as part of the lock. Hollow-core doors, thin panels beside the lock, and hinge screws that barely bite into the frame all undo the value of a strong cylinder. The locksmith checks how the door hangs, whether it drags or needs a shoulder to close, and whether the hinges are on the secure side. Glass close to the lock is noted, because a hand through a broken sidelight can reach an inside thumb-turn. None of this rules out an upgrade; it shows which supporting pieces belong in the plan so the whole opening is brought up together.

Fitting a heavier deadbolt
When the existing deadbolt is light or worn, the locksmith fits a graded deadbolt through the same bore where possible. The bolt throws a full inch and carries a hardened steel pin that turns under a saw blade, and the housing keeps part of the bolt supported against a kick. The latch is set in the edge bore with the correct backset, the exterior housing and interior thumb-turn are joined through the door with the long screws, and the final tightening is done by hand so nothing strips. The bolt is then thrown with the door open and closed to confirm it extends completely.

Fewer keys, clearer purpose
Many customers finish the visit carrying fewer keys than they started with. Exterior doors keyed alike mean one key for the house; a small master system means a manager carries one key for the whole premises. Each key has a known job. The locksmith explains which key opens which door and leaves that in writing, so the tenth person to ask does not get a shrug. Should you add a door later, a gate, a garage entry or a new office, it can join the same system so you keep the single-key convenience without opening a fresh keyway.

What affects the quote
- 1
Condition of the door itself
A solid door that hangs true takes hardware straight away. A dropped, swollen or hollow door may need hinge work, shimming or a recommendation to replace the slab before the lock is worth fitting.
- 2
Hinge and door edge work
Long hinge screws, a hinge-side security stud or repair to a chewed door edge are small items that add up on a door that has been forced before.
- 3
Glass near the lock
Sidelights or glazed panels beside the deadbolt may call for a different function or extra hardware to keep the inside turn out of reach, always keeping easy exit in view.
Same fees day, night or weekend.
High Security Locks: questions
Are high security locks only for businesses?
Not at all. Homes are the most common place they are fitted, especially after a move, a break-in nearby, or the realisation that too many keys have been handed out over the years. A graded deadbolt with a patented cylinder and a reinforced strike is a modest, quiet upgrade for a front or side door. Businesses tend to go further, with laboratory-rated cylinders, heavy lock bodies and a documented key system across many doors.
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.
Will my door look different afterwards?
Barely. A high security cylinder sits in the same place as the old one and is usually distinguished only by a different keyway shape and sometimes a hardened collar. A graded deadbolt is a standard-looking deadbolt in your chosen finish. The reinforced strike is longer than the plate it replaces and the wrap-around reinforcer, if used, shows as a neat metal band on the door edge. The difference is felt when you lock up, not seen from the street.

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 where homes span several eras, one street may have original mortise locks and the next builder-grade cylinders. A locksmith working here carries parts for both, so whichever door he meets, the job finishes in one visit.
37%
Single-detached houses make up about 37% of homes in Mississauga (2021 Census).
In buildings, the suite door often has a closer and a heavy frame, and the deadbolt sits in a metal or metal-clad door. A locksmith fitting or rekeying one brings the tools and cylinders that suit that construction rather than a wooden house door.
