High Security Locks
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.
High Security Locks
In plain words
For a business, high security locks are as much about paperwork as metal. A restricted or patented key system registers the premises with the locksmith, names who may order keys, and numbers every key cut. That is what turns a lost staff key from a mystery into a line in a log. The hardware backs it up: cylinders with sidebars and hardened inserts, heavy-duty deadbolts or mortise locks, and strikes set into the structure. Where several doors are involved the keys can be arranged so a manager carries one key and staff carry keys that open only their own areas.
How the visit goesThe restricted keys you bought years ago are no longer restricted; the locksmith mentioned the patent has run out and blanks are sold openly. Your key control quietly stopped being control.

How the visit goes
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.
Retiring the old keys and closing gaps
Part of the visit is making the old keys meaningless. Once the new cylinders are in, every previous key is tried to confirm it no longer operates anything, and any remaining door on the old keyway is either upgraded or at least rekeyed so an unknown copy has nowhere to go. The locksmith also closes small gaps found during the assessment: replacing hinge screws with long ones, adjusting a closer, adding a cylinder guard, or moving a thumb-turn away from glass. The door leaves the visit as one coherent assembly rather than one strong part among weak ones.
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 affects the quote
Same fees day, night or weekend
1Number of keys cut
Every key is cut from code on a machine that handles side bitting or angled cuts, so the count of keys you want at handover is a real line rather than a rounding error.
2Master keying
Arranging staff keys, area keys and a manager key on one system takes bench time to plan and pin, and the more levels you want, the more careful that planning is.
3Mortise 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.
High Security Locks: questions
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 about the glass panel next to my front door?
A sidelight within reach of the inside thumb-turn is the weak point of an otherwise strong door, since a broken pane lets a hand reach the turn. Options include moving the deadbolt further from the glass, a lock function that needs a key inside as well, or a laminated pane. Because everyone must still be able to leave easily, the locksmith talks through the trade-offs and helps you pick the arrangement that suits your household.
Do high security locks need special maintenance?
Only light care. Use the dry lubricant the locksmith recommends once or twice a year, never oil, which gathers grit around the finger pins and sidebar. Keep the keyway free of debris and insert the key fully before turning. In winter, warm a resisting key in your hand or use a de-icer rather than forcing it. Check hinge and strike screws each season so the door stays aligned. Treated this way the cylinder lasts for decades.
