High Security Locks

Open 24/7

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.

In plain words

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.

Sound familiar?Mississauga

The call: A 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

Scene 1
Who holds keys and who should
For a business or a rental, the locksmith asks to see the key list, or helps you start one. Which keys exist, who carries them, which doors they open, and what happens when someone leaves. This is where the case for a patented or restricted key system becomes clear, because the system replaces guesswork with a register: every key numbered, every order authorised by a named person, and no blanks available outside the locksmith who manages it. The locksmith also asks how many people need to reach each area so the keying plan reflects the way the building actually runs.
Scene 2
Upgrading the cylinder in place
Where the existing lock body is sound, the locksmith removes the ordinary cylinder and fits a high-security one of the same format, so your deadbolt or lever stays and only the working heart changes. The new cylinder brings a sidebar released by finger or rotating pins, hardened steel inserts in the path of a drill, and a keyway that accepts only the controlled blank. Keys are cut from code on a machine that handles the side bitting. The tailpiece or cam is matched so the bolt throws fully, then the cylinder is fixed with its set screw and tested with every key.
Scene 3
A known number of keys
The most noticeable change is not in the door but in your head. You know exactly how many keys exist, who holds each one and that nobody can add to that number without your authorisation. The system is registered in your name with the locksmith, so a request for an extra key comes back to you rather than being filled at a counter somewhere. Keep the authorisation card or login details somewhere safe and separate from the keys. When a key is lost, tell the locksmith; the record is updated and you can decide together whether that key's loss warrants any further step.

What shapes the quoteErindale Lock Experts

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.
Strike and frame reinforcement: A reinforced strike with long screws is modest work on a healthy frame. Deepening the pocket, filling split wood, fitting a jamb plate or a wrap-around reinforcer adds materials and time.
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.

Let's clear a few things up

What is bumping, and does this stop it?

Bumping uses a specially cut key that is struck while under light turning pressure, bouncing the pins to the shear line for an instant so an ordinary cylinder opens. It works on many standard pin tumblers. A high security cylinder needs its sidebar released by separately positioned finger or rotating pins at the same moment, and a bump key cannot set those, so the plug stays locked. It is one of the clearest advantages of the upgrade.

Is a high security cylinder really pick proof?

Nothing is beyond a laboratory with unlimited time, so the honest measure is minutes, not absolutes. Rated cylinders are tested to resist skilled picking and impressioning for a set period, and drilling and forcing for another. In the real world that matters because someone at a door has seconds, not a workbench. The sidebar and false grooves in the pins give a picker nothing reliable to feel, and the hardened inserts stop a bit, which is why these attacks move on to easier doors.

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.
