High Security Locks
After the attempted break-in the police officer pointed at your door and said the strike plate was held by two short screws. Nobody got in, but you have looked at that door differently every evening since.

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 goesYou 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.

How the visit goes

- 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.

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.

Ordering keys the right way
Extra keys are now a small procedure rather than an errand. An authorised person contacts the locksmith, the request is checked against the system record, and the key is cut from code so it works as cleanly as the first. New keys are numbered and added to the register. Businesses often issue keys against a signature and collect them when someone leaves, which the register makes simple. Homeowners typically keep two or three spare keys and hold onto the authorisation card. A key cut from a worn copy would not release the sidebar properly, which is one more reason the code route is the only route.

What affects the quote
- 1
Retiring the old keyway
If other doors stay on the old key for now, they may need rekeying so an unknown copy has nowhere to go; that is additional cylinder work alongside the upgrade.
- 2
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.
- 3
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.

High Security Locks: questions
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 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.
Do I need to replace my whole deadbolt or just the cylinder?
It depends on what you have. If the deadbolt is a good heavy unit that throws a full inch into a proper strike, a high security cylinder can replace the ordinary one and the rest stays. If the deadbolt is light, worn or throws a short bolt, a new graded deadbolt with a hardened bolt is the sensible base and the high security cylinder goes into that. The assessment tells you which, door by door.

What the census means at the door
43%
Homes of every age. About 43% of homes in Georgina 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.
83%
Mostly houses. Single-detached houses make up about 83% of homes in Georgina (2021 Census).
Garage entry doors on detached houses are often the household's real front door, used more than the formal entry. They deserve the same quality of lock, and keying them alike with the house means one key does the whole daily routine.
