Steel, fibreglass, solid wood or a century-old panel door with a wobble: each takes a different approach to hardware. We measure the backset, the thickness and the bore before ordering anything, so what arrives fits the first time.
A master key system is a small piece of design work, and we approach it that way. We sit down with whoever runs the building and sketch out who needs to open which doors, where keys must never cross, and how many spare positions to leave for growth. Only then do we pin cylinders and cut keys, so the system still makes sense five years and three staff changes later.
The key you reach for. The door you come home to. Good locksmith work begins with understanding how you use them.

Locksmith services
Below are the jobs we handle most often. For each one you will find what it fixes, how a visit usually goes and what information helps us arrive with the right parts. If two services sound alike, call and we will explain the difference in a sentence.
Home Lockout ServiceAfter a week of humid weather the back door has swollen in its frame.
Business Lockout ServiceAfter last night's power flicker the card reader beside the clinic door shows nothing.
Broken Key ExtractionThe key went in like any other morning, you turned it, and something gave with a small metallic click.
Break-In Damage Lock RepairThe shop's aluminum door has a bent meeting stile and the hookbolt is jammed half out.
Seized & Jammed Lock OpeningThe old mortise lock on the front door of the house turns the key halfway and stops with a dull clunk.
Lost Keys — Same-Visit RekeyYou were shovelling the driveway after dark and the ring must have slid out of your coat pocket somewhere under a metre of snow.
Lock RekeyingThe builder handed over your new home with a stack of identical keys, and you know the framing crew, the painters and the flooring installers all used a construction key during the build.
Deadbolt InstallationYou bought a keypad deadbolt online and pulled the old one off, only to find the hole in the door is a different size and the bolt latch sits at a backset the new kit does not list.
Lock Replacement & UpgradeEvery morning the front door key needs the same little dance: push in, lift, wiggle, turn.
Vintage Mortise Lock ServiceThe knob flops loose on its spindle and never springs back to level.
Smart Lock InstallationThere are four copies of the front-door key floating around: one with the cleaner, one with a neighbour, one on a hook at your parents' place, and one you honestly cannot account for.
Gate & Building Entry LocksA neighbour mentions, in passing, that the key from three tenants ago still lets him into the building's front door.
Mailbox Lock ReplacementSomeone tried to pry the little door on the mailbox open with a screwdriver, and though the mail sitting inside is untouched, the lock now sits crooked in its hole and the key barely catches when it is turned.
You bought a keypad deadbolt online and pulled the old one off, only to find the hole in the door is a different size and the bolt latch sits at a backset the new kit does not list. The door is now open and the box is on the counter.
Deadbolt InstallationYou run a home office with client files and equipment, and your insurer has asked what kind of lock is on the door. The honest answer is the builder's knob lock and a light deadbolt from when the house was new.
High Security LocksYou reached the front step with the groceries, patted every pocket twice, and the house key is simply not there. It was on the ring this morning. Now the door is locked, the lights are off, and nothing you have on you opens it.
Home Lockout ServiceHigh security
Interchangeable-core high security cylinders let a business change a lock in moments by swapping the core with a control key, so a lost key means a core swap rather than a locksmith visit for every door. The page explains where that suits and where it does not.
After the attempted break-in the police officer pointed at your door and said the strike plate was held by two short screws.
Every morning the front door key needs the same little dance: push in, lift, wiggle, turn.
You bought a keypad deadbolt online and pulled the old one off, only to find the hole in the door is a different size and the bolt latch sits at a backset the new kit does not list.
The shop's aluminum door has a bent meeting stile and the hookbolt is jammed half out.
Commercial
Office managers, franchise owners, property managers and shopkeepers all come through the commercial pages. The work is the same trade as residential locksmithing, but the hardware is heavier, the keying is planned and the paperwork matters more.
High security
The new manager took over the shop last month and only now needs the back-office safe open, but the combination the previous owner was supposed to leave in writing never turned up anywhere in the handover file.
A homeowner inherited a heavy old dial safe from a parent's house, moved it into the new place, and has no idea whether the bolt-work still works, whether the lock is sound, or how it should be anchored.

01
Together we list the doors, then decide who should open everything, who should open a floor and who should open one room. That structure becomes the keying chart.
02
Every cylinder is pinned so the right keys work and nothing else does. We check each combination against the chart as we go, not at the end.
03
You receive the keys labelled by level, the chart and a plain explanation of how to add a door or retire a key later without redoing the whole system.
Peel, Ontario
2021 Census
About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.
In neighbourhoods with a mix of older and newer homes, the finishes on the doors vary widely: aged brass, satin nickel, matte black. A locksmith serving such an area keeps a range of finishes so replacement hardware suits each house.
Single-detached houses make up about 37% of homes in Mississauga (2021 Census).
Where housing is mostly apartments and condos, mailbox locks are a regular call. A worn or lost mailbox key is a small job that a locksmith handles alongside the suite door, and the new lock comes with fresh keys cut on the spot.
Yes. Like any pin tumbler it can be repinned to a new combination by a locksmith who holds the system, so a departed employee's key can be retired without replacing hardware. Some lines use interchangeable cores that swap in moments with a control key, which suits businesses with frequent turnover. Rekeying stays within your registered keyway, so the key control you paid for continues after the change.
No. The blank for a patented keyway is distributed only through the manufacturer's network to locksmiths who hold the system, and the side milling or angled cuts need a machine set up for that line. A kiosk would have neither the blank nor the cut. Extra keys come through your locksmith, cut from code, once an authorised person has approved the order. That routine is a small inconvenience compared with never knowing who has a copy.
Tell your locksmith so the register is updated, then decide together what the loss means. If the key was lost with nothing identifying your address, the practical risk is low and many people simply strike it off. If it went missing with identification or from a known person, the affected cylinders can be repinned so that key stops working while the rest of the system continues. Because the keyway is controlled, you know that no further copies exist.
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.
Older houses in Mississauga get a locksmith who respects them. We work around original trim, keep period hardware where it can be kept, and match finishes when something new is needed so the door still looks like it belongs to the house. Modern security can sit behind a hundred-year-old face; that is a matter of choosing parts carefully.
