High Security Locks

You have lost count of how many people have had a key to your house over the years: cleaners, a contractor, a former partner, the previous owner's family. The lock still works, but you no longer know who else it works for.

In plain words

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.

The call
The pharmacy stockroom, the server closet or the cash office is protected by the same ordinary cylinder as the staff washroom. One lost key on a lanyard would open all of them.

How the visit goes

  1. Scene 1

    The fit of new hardware to old doors

    Older houses in this region have doors that predate modern hardware: narrower stiles, a mortise pocket already cut, a thick slab door or a steel-clad door with a specific backset. The locksmith measures the bore, backset, door thickness and edge preparation so the chosen deadbolt or cylinder fits without hacking at the door. Where a mortise lock is present, a high-security mortise cylinder often replaces the old one directly. Where a knob lock is the only lock, the assessment includes where a new deadbolt bore would sit and whether the frame can take a proper strike.

  2. Scene 2

    Setting up controlled keys

    The key system is registered to you before the first key is cut. The locksmith records the system, the authorised signatories and the number of keys issued, and hands you the authorisation card or online validation details. Every key is cut from code rather than copied, because the angled cuts or side milling must be exact for the sidebar to release. Extra keys later are ordered by an authorised person and logged, and blanks are not sold outside the manufacturer's network. This is what makes a key stop being a thing anyone can duplicate at a kiosk.

  3. Scene 3

    A key plan that survives staff changes

    For a business, the handover includes a key schedule showing every cylinder, every key number and who holds it. When someone leaves, their key comes back and is struck off; if it does not come back, you know exactly which doors it opened and can decide whether one cylinder or several should be repinned. Because the keyway is restricted, a departed employee cannot quietly keep a copy. New hires are issued a numbered key against a signature. The plan lives in a folder or spreadsheet, and the locksmith keeps a matching record so the two can be reconciled whenever you like.

What shapes the quoteMarkland Woods Locksmith Co.

Number of doors
Each door gets its own cylinder or lock, strike work and testing. Several doors on one keyway share the setup cost of the key system but add hardware and time per opening.
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.
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.

Frequently asked questions

What does key control mean in practice?

It means your key can only be copied through the locksmith who manages your system, after checking that the person asking is on your list of authorised names. Blanks for the keyway are not sold to hardware stores or kiosks while the patent lasts. Each key is numbered and recorded, so you know how many exist. For a home that ends the worry about old copies; for a business it turns a lost staff key into a known, manageable event.

How do I order extra keys later?

An authorised person contacts the locksmith who holds your system, quotes the system reference, and the key is cut from code and numbered into the register. Some systems use a physical authorisation card, others an online validation, and business systems often require a signature that matches one on file. The key is collected or delivered, and the record shows the new total. It is deliberately not something a stranger with your key can do.

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.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 38 in 100 homes · mixed ages
  • About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.Where housing is mixed, doors that have been replaced sit beside doors that never were. A new door in an old frame, or an old door in a repaired frame, needs its strike and hinges checked together so the whole assembly works as one.
  • Single-detached houses make up about 37% of homes in Mississauga (2021 Census).Townhouse rows often share a keyway chosen by the builder. A locksmith can move a household onto a keyway of its own so a neighbour's key, or a key from the construction phase, no longer has any chance of fitting.
