Residential Locksmith Newmarket
Locks, keys and door hardware for houses, townhomes and condos across Newmarket. Rekeys, deadbolts, patio doors, smart locks and lockouts, 24 hours a day.
Quick answer
A residential locksmith in Newmarket handles the locks on a home: rekeying cylinders after a move or a lost key, installing and repairing deadbolts, fixing patio and garage door hardware, fitting smart locks, and opening a door when you are locked out. Most home jobs finish in one visit, and typical response to a Newmarket address is 20 to 30 minutes.
Almost every call we take from a Newmarket homeowner falls into one of three buckets. Something stopped working. Someone holds a key they should not have. Or the door was never properly secure to begin with. A residential locksmith deals with all three, usually in a single visit, and usually for less money than people brace themselves for.
We have been working on houses in this town since 2000 — the 1980s stock around Glenway Estates, the big subdivision builds off Mulock and Bathurst, the century homes on Main Street South, and the newer East Gwillimbury and Sharon builds where the hardware is still shiny and still keyed to a cylinder that half the trades in the region have handled. Different houses, different failures, and the answer is not always a new lock.
This page covers every home service we offer, when each one is genuinely the right call, and what it costs. If you already know what you need, the links below go straight there. If you do not, read the door-by-door walkthrough — it is the same order a technician works in when you ask for an assessment.
What a residential locksmith actually does
Four categories cover roughly ninety per cent of home work. Most jobs are a combination of two of them.
Rekeying
Same locks, new key. The cylinder comes apart, the pins are swapped to a new combination, and every old key stops working that afternoon. The cheapest honest way to take control of a house.
Lock replacement
New hardware when the existing set is worn out, mismatched across doors, or too weak to be worth rekeying. Grade 2 or better on anything that opens to the outside.
Hardware and door repair
Sagging doors, strikes that have drifted out of alignment, latches that no longer catch, patio doors you have to lift before they will lock. Often twenty minutes of adjustment and no new parts at all.
Lockouts
Non-destructive entry to houses, townhomes and condos. Picked or bypassed in the large majority of cases. Drilling is a last resort and we tell you before we start, not after.
The line between these blurs constantly. A homeowner who calls about a key that will not turn often needs a strike plate adjusted rather than a new cylinder. Someone who calls to change the locks after a break-up frequently only needs the cylinders rekeyed at a third of the cost. We will tell you which one you are looking at before we quote it.
The one thing we will not do is talk you into hardware you do not need. If your deadbolts are five years old, decent quality and working smoothly, rekeying them is the correct answer and replacing them is a waste of your money.
How a home security assessment works, door by door
This is the actual sequence a technician follows. You can walk it yourself in fifteen minutes.
The front door
Deadbolt first. Throw the bolt with the door open and measure how far it projects — under one inch and it is a Grade 3 builder bolt that a shoulder will beat. Then the strike plate: pull it off and look at the screws. Three-quarter-inch screws into soft pine jamb are what most builders leave behind. Three-inch screws reaching the stud behind the frame is the single cheapest security upgrade in the house.
Back, side and mudroom doors
These are where the actual break-ins happen, because they are out of sight from the street. Check that every one of them has a deadbolt and not just a latching knob. Check the glass beside the door — if a pane is within arm reach of the thumbturn, a double-cylinder bolt or a laminate film changes the calculation.
The patio slider
Slide it, then try to lift it. If the panel rises more than about a centimetre in the track, it can be lifted out of the frame with the latch still engaged. The factory mortise latch on most Newmarket sliders is a hooked piece of pot metal and is not a lock in any serious sense.
The garage and the door from the garage into the house
The man-door on the side of the garage is the most consistently neglected door on any property. Worse, the door between the garage and the house is very often a hollow interior slab with a privacy knob. Once someone is in the garage they are working out of sight, and that door is all that is left.
The key audit
Write down everyone who has ever held a key: former tenants, the last owner and their adult children, a cleaner, a dog walker, a contractor, the neighbour who watered plants in 2019. If the list is longer than the number of people living there now, you have your answer.
Nothing in that walkthrough requires a locksmith. What a locksmith brings is the fix: boring a door that never had a deadbolt, reinforcing a strike, adding a keyless entry lock so nobody hides a key under a flowerpot, and getting every exterior door onto one key so the whole system is actually usable.
Which service is the right call for your situation
People call with a symptom, not a service name. Here is the honest translation.
- Just bought the house, keys handed over at closing — a full rekey of every exterior cylinder onto one new key. See new home lock changes.
- Lost a single key and no address on the fob — rekey the affected doors only. You do not need new hardware.
- Key turns but the bolt drags or grinds — usually alignment or a dry cylinder, not a failed lock. Book a lock repair and expect a cheap visit.
- Knob or lever is loose and spinning — a set screw or a worn spindle. Twenty-minute job.
- Hardware is 20+ years old, brass worn through, key sloppy in the plug — replace it. Rekeying a dying cylinder buys you six months.
- Tenant moved out of a basement unit — turnover rekey. See rental property lock changes.
- Want codes instead of keys for a cleaner or a teenager — a smart deadbolt on the door they actually use, not on all five.
- Locked out right now, kids or pets inside, or something on the stove — call, say so, and it becomes a priority run.

Newmarket houses and the locks that came with them
Housing stock in this town clusters into a handful of eras and each one has a signature problem. The 1980s and early 1990s subdivisions around Bristol-London and Huron Heights came with Weiser and Schlage hardware that was decent for its day; forty years on the springs are tired and the plugs are sloppy, and those are replacement candidates rather than rekey candidates. See Weiser lock repair for what is still worth saving.
The late-1990s and 2000s builds — Stonehaven, Summerhill Estates, Woodland Hill — are the sliding patio door generation. Those doors are now twenty-plus years old, the rollers have flattened, and the panel sits low enough that the latch misses the keeper entirely. Homeowners describe this as a broken lock. It is almost never the lock.
Newer builds in East Gwillimbury, Holland Landing, Sharon and Queensville arrive with SmartKey-equipped Weiser or Kwikset cylinders and a builder key problem that nobody explains at closing. Those houses need a rekey on move-in day, not a lock change.
And the century homes off Main Street South are their own category: original mortise locks, doors that have moved with the seasons for a hundred years, and frames that will not accept modern hardware without proper prep. That is mortise lock work, and it is worth doing properly.

Frequently asked questions
How much does a residential locksmith cost in Newmarket?
Most home jobs land between $95 and $340 including parts. A daytime house lockout is $95 to $180. A single cylinder rekey is $75 to $130 with additional cylinders at $25 to $45 each on the same visit. A supplied and installed deadbolt runs $145 to $260. Overnight and holiday calls carry a premium, and the exact figure is confirmed on the phone before dispatch.
Should I rekey or replace the locks in my house?
Rekey if the hardware is under about fifteen years old, turns smoothly and is at least Grade 2 — you get a brand new key and every old key dies, at a fraction of the cost. Replace if the plug is sloppy, the finish is worn through, the deadbolt throws less than an inch, or your doors are on four different keys and you want them on one.
How fast can someone get to my house?
Typical response to a Newmarket address is 20 to 30 minutes, day or night. Aurora, East Gwillimbury and Holland Landing usually add 5 to 15 minutes. If there is a child or a pet locked inside, or something left on the stove, say so when you call and the job is moved to the front of the queue.
Can you get me in without damaging the door?
In the large majority of house lockouts, yes. Standard residential pin tumbler locks are picked or bypassed and nothing is damaged. High-security cylinders and a small number of jammed or broken locks have to be drilled, in which case the cylinder is replaced afterwards. You will be told that before any drill comes out of the van, not after.
Can you put every door in my house on one key?
Yes, and it is one of the most common requests. Provided the cylinders are the same keyway family — most residential Schlage, Weiser and Kwikset hardware is — every exterior door, the garage man-door and the patio deadbolt can be keyed alike on a single visit. Where a cylinder is incompatible we swap that one cylinder rather than the whole lock.
Do I need a locksmith for a door that sticks or will not latch?
Often yes, and it is a cheap visit. Doors move with the seasons, hinges sag, and the strike drifts out of alignment until the latch no longer drops in cleanly. That gets diagnosed as a broken lock constantly. Realigning a strike, shimming a hinge or filing a keeper is usually twenty minutes and no new hardware.
Is it worth putting smart locks on a house in Newmarket?
On the one or two doors you actually use, usually yes — codes for cleaners and contractors beat hidden keys, and nobody gets locked out. On every door in the house, usually not. Cold matters here: alkaline batteries lose meaningful capacity below minus fifteen, so change them every autumn and keep a mechanical key override.
