How we can help
Choosing a service is easier when you know what each one actually changes. Rekeying changes the key, replacement changes the hardware, repair keeps what you have working, and installation adds something new. The sections below sort our work along those lines.
Lockouts
Lockout Services
After a break-in the door is evidence, then it is a problem. Once you are ready, we repair what was damaged, replace what cannot be trusted and rekey what might have been compromised.
Home Lockout ServiceThe keypad on the smart lock blinks once and goes dark.
Business Lockout ServiceMinus eighteen with a wind, and the exterior cylinder on the shop door has frozen solid overnight after yesterday's slush.
Broken Key ExtractionOvernight the deadbolt froze, and this morning the key would only turn partway.
Break-In Damage Lock RepairThe patio slider is sitting crooked on its track.
Seized & Jammed Lock OpeningThe key turns a full circle without any resistance and the deadbolt stays exactly where it is.
Lost Keys — Same-Visit RekeyThe lawyer's envelope held two keys for the new house.

Residential locksmithing is small, careful work on the doors you use every day. We take the time to look at how the door hangs, how the latch meets the frame and how the key turns, because those details decide whether a lock lasts.
Lock RekeyingEvery copy of your house key seems to work a little differently. One needs a jiggle, another sticks halfway, and the original wore down years ago.
Deadbolt InstallationThe old deadbolt has grown lazy. You turn the thumb-turn and the bolt creeps out halfway, then needs a second push with the door pulled tight.
Lock Replacement & UpgradeEvery morning the front door key needs the same little dance: push in, lift, wiggle, turn. It has been getting worse for a year, and this week it took three tries in the cold before the deadbolt finally gave.
Vintage Mortise Lock ServiceSomeone painted the door years ago without removing the hardware. The faceplate, the strike and the little thumb-turn are all under several coats, the deadbolt scrapes when it moves, and the knob is stiff enough to…
Smart Lock InstallationArthritis has made the small house key hard to grip and turn, especially with gloves on in January. Pressing a few buttons, or tapping a fob against the lock, would make coming home in winter far easier.
Gate & Building Entry LocksA neighbour mentions, in passing, that the key from three tenants ago still lets him into the building's front door. Nobody changed it after he moved out, and now the property manager wants to know exactly how many keys…
Mailbox Lock ReplacementYou've just moved in, and the mailbox compartment in the lobby came with a single key the previous owner mailed back separately, or never handed over at all. As far as anyone can tell, the lock still answers to a…

High Security Locks
We describe cylinders by what they resist: picking, bumping, drilling, wrenching and pulling. We describe key systems by who can order a copy.

Commercial
Commercial Locks
A business that has grown from one unit to three usually has three key rings and no plan. A master key system tidies that into a single hierarchy, and the pages here explain the design, the installation and how new doors are added later.

Car Keys
Before any key is cut or programmed for a vehicle we check that the person asking has a claim to it. Registration or ownership paper and matching photo identification are what we ask for.
Car Lockout ServiceYour toddler is buckled in the back seat, the doors locked when you shut yours, and your keys are on the front seat beside your…
Car Key ReplacementThe engine cranks, catches for a second and dies, and a small key-shaped light keeps blinking on the dash.
Spare Car Key DuplicationThe blade on the everyday key has gone shiny and thin along one edge, and lately it needs a wiggle before the ignition catches.
Key Fob ProgrammingA fob went missing weeks ago somewhere between a coat pocket and a parking lot, and a spare has covered the gap since.
Transponder Key ProgrammingSince the remote starter was installed last month, the original key has started acting strangely, the car catches on the first…
Ignition Lock RepairThe key slides in fine and turns without any resistance at all, and the dash lights flicker, but nothing catches.
