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.

How the visit goes

  1. Scene 1

    The bolt, the pocket and the strike

    A deadbolt is only as good as how far it reaches and what it reaches into. The locksmith measures the throw of the bolt with the door closed, checks that it fully extends without the door being lifted or pushed, and looks at the pocket it enters in the jamb. A shallow pocket, a stamped strike plate and screws barely longer than a thumbnail are the usual finding on a builder-grade door. Then the frame is examined for splits, soft wood and gaps behind the jamb, since a kick lands on the strike, not on the cylinder.

  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

    Looking after a precision cylinder

    High-security cylinders are finer mechanisms than the pin tumblers they replace, and a little care keeps them turning sweetly. Use only the dry lubricant the locksmith recommends, once or twice a year and sparingly, and never household oil, which gathers grit around the finger pins and sidebar. In cold weather, if the key resists, warm it in your hand or use a de-icer rather than forcing it. Insert the key fully before turning. Keep a spare key indoors so a bent or worn key is retired rather than pushed on. Treated this way, the cylinder outlasts the door around it.

What shapes the quoteDavisville Lock & Key Co.

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.
Commercial lock bodies
Heavy-duty deadbolts, mortise locks, narrow-stile deadlocks and cylinder guards for storefront and warehouse doors are heavier hardware than residential deadbolts and priced as such.
Mortise and older doors
An existing mortise pocket, a thick slab door or an unusual backset can mean a specific cylinder or an adapted preparation, which takes longer than a standard bore.

Ask us anything about locks

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.

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.

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.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 58 in 100 homes · older homes
  • About 58% of homes in Toronto were built in 1980 or earlier, according to the 2021 Census.Older doors are usually thicker and made of solid wood, which is good news. They take a deadbolt well, hold longer strike screws, and reward reinforcement. The locksmith measures the thickness and backset so new hardware fits without fresh holes.
  • Single-detached houses make up about 23% of homes in Toronto (2021 Census).Suite doors in buildings often have a viewer, a chain and a deadbolt fitted at different times. A locksmith can tidy that into one sound arrangement, with a properly set deadbolt and a strike that holds, without altering the door's face.
