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

A high security cylinder is rated by independent laboratory testing that times how long it holds out against picking, impressioning, drilling, prying and wrenching. The lock body and deadbolt carry a separate hardware grade for strength, cycle life and finish. A locksmith reads those ratings for you and matches them to your door, because a rating on the box means nothing if the door frame is thin or the bolt barely enters the jamb. The visit usually ends with a heavier deadbolt, a reinforced strike fastened into the framing and a cylinder whose keys cannot be copied at a kiosk.

The call: Your 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

Scene 1
Reading the cylinder you have now
The existing cylinder tells the locksmith a great deal. A standard pin tumbler with an open keyway can be picked, bumped and duplicated by anyone with the blank. Worn pins let a key that is not quite right jiggle it open. A cylinder that spins loosely in its housing or shows a scratched face has been attacked or simply worn out. The locksmith identifies the format, whether key-in-knob, rim, mortise or interchangeable core, because that determines which high-security cylinders will drop into your present hardware and which will need a new lock body altogether.
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 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 shapes the quoteAncaster Heights Locksmith Pros

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.
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.
Cylinder only or full deadbolt: Swapping the cylinder inside a sound deadbolt is a smaller job than fitting a new graded deadbolt through the door, and a knob-only door that needs a fresh bore is bigger again.

Your questions, our answers

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.

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.

What happens when the patent on my keys runs out?

The mechanical resistance of the cylinder does not change, but blanks may become openly available, so copy control weakens. Manufacturers issue new patented keyways as older ones expire, and the usual answer is to move to the next generation by changing cylinders and keys while keeping the lock bodies. Your locksmith notes the patent term at handover so the date is on the calendar rather than a surprise years later.
