Residential Lock Installation in Ontario: Every Door, One Key
Short answer: For a Ontario home, a sensible baseline is a Grade 1 or AAA-rated deadbolt on every exterior door, Grade 2 knobs or levers for the entry latches, and Grade 3 interior sets where nobody will lean on them hard. Pick a single keyway, such as Schlage SC1 or Kwikset KW1, so every exterior lock can be keyed alike, and choose one finish for the whole house.

New doors change the math. When a remodel brings in a fiberglass front door, a steel garage entry door or a set of solid-core bedroom doors, someone still has to bore them, cut the latch and strike mortises, and hang hardware that fits. Contractors often leave that last step to the homeowner, which is exactly where residential lock installation comes in. We match hole sizes to the hardware template, set backsets that suit the lockset, and fit strikes to the jamb so latches catch on the first push. If your doors arrived pre-bored, we confirm the prep matches the locks you picked before you open boxes you can't return.

Residential Lock Installation in Ontario: what to expect
Walk around a typical single-family house and count what actually locks. There's the front entry, often with a handleset and a deadbolt. A back or side door to the yard. The door between the attached garage and the house. A garage service door to the side yard. One or two sliding patio doors, sometimes a pair of French doors. Then the inside: bathrooms and the primary bedroom that need privacy sets, halls and pantries that need passage latches, closets that only need a dummy knob, maybe an office or a gun closet that deserves a keyed lock. Add a side gate or two and a detached shed, and an ordinary house has well over a dozen openings. Residential lock installation done properly assigns each one a function before anyone picks a brand. Exterior doors get a deadbolt plus a latch that can be keyed alike. Interior doors get the lightest function that does the job, because keyed locks on interior doors turn into lockout calls. The garage-to-house door gets treated like an exterior door, since an open garage makes it one. Planning the list first is how you avoid buying three of something you needed one of.
What we can do on-site
- Front entry handlesets and deadbolts. The front door gets the most use and the most scrutiny. We install handlesets with a thumb-latch grip and a separate deadbolt, or a matched knob or lever with a deadbolt above it, and we line the deadbolt up so it throws its full inch without a shoulder push. The lower handleset screw gets a solid anchor, not just a hollow door skin.
- Garage-to-house door hardware. Garage entry doors take abuse: grocery bags, bikes, scooters and the occasional bumper. Choose a lever with a sturdy spring cassette instead of a lightweight builder set, and a deadbolt whose strike is screwed into the stud. If you like the idea of a keypad here, a keypad deadbolt lets family members walk in from the garage without fishing for keys.
- Sliding and French patio door locks. Sliding glass doors use a mortise hook latch that's often worn or misaligned by the time a house changes hands. We replace the latch and handle with a set that fits the door's stile, then add a secondary lock, such as a keyed foot lock or a bar that drops into the track, so the panel can't be forced aside.
- Interior privacy, passage and closet hardware. A keyed lock on an interior door is sometimes the right call: a home office, a room rented to a housemate, a closet holding medication or firearms. Those doors want an entrance-function lever or a keyed deadbolt, keyed differently from the exterior. We'll gently argue against keyed locks on young kids' bedrooms, where they mostly produce frustration and butter-knife repairs.
- Keying the whole house alike. New locks ship with random keys, often a different set in every box. During installation we rekey each exterior cylinder to one combination, so a single key covers the front door, the back door, the garage entry, the garage side door and the gate. If you'd rather keep the key already on your ring, we pin the new cylinders to match it.
What's different about Ontario
Renters in Ontario apartments usually need the landlord's written permission before installing new locks, and most leases require management to keep a working key. If you want a better deadbolt or a keypad, ask first and offer to provide a key. Owners fitting hardware across several units can standardize on one brand and keyway, which makes rekeys between residents faster.
Inland summers bake exterior hardware. Dark finishes on west-facing doors get hot to the touch, batteries in keypad locks drain faster, and wood doors swell and shrink enough to pull latches out of alignment. We set strikes with a little seasonal tolerance, suggest checking batteries before the hottest months, and recommend light or PVD finishes for doors in full afternoon sun.
Homes built before 1980 in Ontario often have doors that have been planed, repainted and rehung several times. Expect a mix of 2-3/8 and 2-3/4 inch backsets, the occasional mortise lock hiding behind a newer knob, and jambs scarred by three generations of strike holes. Residential lock installation in an older house starts with measuring every door, then choosing adjustable latches, cover plates and wood repairs so the new hardware sits on sound material.
Example situations
- For example, a remodel where the contractor hung a new fiberglass front door, pre-bored for one lock, and the homeowner bought a two-piece handleset with a separate deadbolt. The door needs a second bore, an edge prep for the deadbolt and a new strike pocket. Fiberglass chips easily, so we'd template from both faces, cut slowly with a sharp hole saw, seal the exposed core and set the strike screws into the studs.
- Picture a family that leaves the garage door up most of the afternoon while the kids ride bikes in the driveway. The garage-to-house door has a privacy knob and nothing else, and its closer spring broke years ago. On a visit like that we'd install a keyed lever and a deadbolt matched to the front-door key, fit self-closing hinges, and adjust the tension until the door latches on its own from any angle.
- Picture a house with a block wall and a wooden side gate that neighborhood kids keep wandering through. The gravity latch lifts with one finger through the gap between the boards. A sensible install would be a keyed gate lock mounted on the yard side that opens from inside without a key, keyed to the house, plus a solid strike block on the post and a closer so the gate shuts itself.
- For example, picture a 2005 tract home near Chaffey High School with fourteen doors still wearing builder-grade polished brass knobs. The owners want matte black levers inside, a handleset and Grade 1 deadbolt out front, and one key for every exterior lock. We'd sort the doors by function first (six privacy, five passage, three dummy pairs), confirm every door uses a 2-3/8 inch backset, swap hardware room by room and rekey the exterior cylinders on the tailgate.
How the visit works
- Walk the house and list every door. We start by walking the property with you and listing every opening: exterior doors, garage entry, patio doors, interior rooms, closets and gates. For each one we note what it needs to do, whether that's lock with a key, lock from inside only, latch without locking, or simply stay closed. That list becomes the order.
- Measure doors and check the existing prep. We also check what the locks will be fastened to. Does the door close square? Do the hinges sag? Is the jamb solid behind the strike, or split from an old kick? Catching these during measuring beats discovering them halfway through, with a door sitting open and no hardware on it.
- Choose hardware, finish and the key plan. With measurements in hand, we help you pick grade, style and finish for each function, or confirm that hardware you already bought will fit. We also settle the key plan: which doors share a key, whether you want to keep your current key, and whether any room or outbuilding needs its own.
- Prep the doors and mount the hardware. Fiberglass and steel doors get the right cutters and slower speeds so skins don't chip and metal doesn't tear. Handleset grips get through-bolts or proper anchors. We also check the weatherstripping, because a swollen seal pushing against the door is a common reason a new latch won't catch.
- Key alike, adjust and test every door. Testing includes the inside. Privacy sets must release from the hallway with the emergency tool, and exterior doors must open from inside with a simple turn, no key needed, unless you've knowingly chosen a double-cylinder deadbolt. We adjust strikes until every door closes quietly and locks without a push.
- Hand over keys and paperwork. Before we leave, you get a count of keys cut, the emergency release tools for privacy locks, and the manufacturer's paperwork for the hardware. We'll show everyone how the deadbolts and any keypads work, and suggest a safer home for the spare key than the planter by the front step.
What affects the cost
- How many doors, and which kinds. Doing every door in one visit is usually more economical than spreading the work across several trips. Travel, setup and keying happen once, and all the cylinders can be pinned together. If budget means phasing the job, start with the exterior doors and the garage entry, then come back for the interior.
- Door prep and repairs. Doors already bored to standard sizes are the quickest. Undrilled doors, holes that need enlarging, a new deadbolt bore above an existing lock, or old holes to fill all take extra time. Fiberglass and steel doors take longer to bore cleanly than wood, because rushing them chips the skin.
- Keying and key control. Keying every exterior lock alike means repinning each cylinder, and matching an existing key means decoding it first. Restricted keyways, master arrangements for an ADU and extra cut keys add to the total. Rekeying during installation costs less than a return trip, because the hardware is already apart.

Advice before you book
- Don't throw away the old hardware until the new hardware is on and working. If a part is missing or the wrong size, the old lock can go back on the door for a night. Afterward, old deadbolts and knobs can go to a scrap metal recycler instead of the trash can.
- Put your money into exterior deadbolts and strikes. A Grade 1 deadbolt with 3-inch strike screws biting into the framing resists far more force than an expensive handleset on a stock strike. Inside the house, economical passage and privacy sets work fine for decades of normal use.
- If a door has glass within arm's reach of the lock, think carefully about the deadbolt. A double-cylinder model stops a reach-through, but it also means hunting for a key to get out during a fire. Many households choose a single-cylinder lock plus security film or laminated glass instead.
- Send photos before the visit. A shot of each door edge, the existing lock and the strike tells us backset, latch type and frame condition. For a whole-house residential lock installation in Ontario, photos help us bring the right cylinders, pins and strike plates on the first trip.
Common errors that cost time and money
- Mixing brands on exterior doors. A Schlage deadbolt in front and a Kwikset set on the garage entry means carrying two keys forever, unless one cylinder gets swapped. Choosing one keyway at the start costs nothing and makes keying the house alike simple.
- Ignoring the garage-to-house door. People reinforce the front door and leave the garage entry on a cheap privacy knob, even though an open garage gives full cover to anyone trying that door. Treat it as an exterior door, with a keyed lock and a deadbolt on the house key.
- Installing a double-cylinder deadbolt on the main exit without thinking about fire. If the key isn't in the lock or hanging right beside the door, anyone inside has to find it in smoke and darkness to get out. Use one only with a clear plan, and never on a bedroom exit.

Frequently asked questions
Can you install locks on a brand-new door with no holes?
Yes. We bore undrilled doors with a jig for a square 2-1/8 inch face bore and 1 inch edge bore, cut the latch and strike mortises, and set the backset to match your hardware. Fiberglass and steel doors get bored from both faces to avoid chipping. If the door came pre-bored, we check that prep against the lock template first.
Is a double-cylinder deadbolt a good idea for my front door?
Only in limited situations. It needs a key on both sides, which stops someone reaching through nearby glass but also slows anyone inside trying to escape a fire. If you choose one, keep the key in a fixed spot right by the door, and never use one on a bedroom door or the only exit. A single-cylinder lock plus security film is often the better answer.
Should I buy Schlage, Kwikset, Baldwin or another brand?
Each of those makes solid residential hardware at different price levels, and Yale belongs on the list too. What matters most is the grade of the exterior deadbolts, a finish suited to your climate and one keyway across the exterior doors. We'll recommend a line based on your doors and budget, and we're glad to install a brand you already prefer.
Do I need HOA approval to change my front door hardware?
Check your community's architectural guidelines. Many HOAs regulate changes to the visible exterior of a home, and some specify finishes or styles for front door hardware. Interior hardware and most garage entry locks don't need approval. If your association requires a particular finish, tell us when you call and we'll quote hardware that meets it.
What's the difference between privacy, passage and dummy hardware?
Privacy sets lock from inside with a button or turn and release from outside with a small tool; they belong on bathrooms and bedrooms. Passage sets latch but never lock, for halls, laundry rooms and pantries. Dummy sets are fixed handles with no latch, used on closets and the inactive side of double doors, usually paired with a ball or roller catch.
Do you install keypad and smart locks as part of a residential job?
Yes. Many households in Ontario put a keypad or smart deadbolt on one or two doors, often the garage entry or the front, and standard keyed hardware everywhere else. We install both, key the smart lock's backup cylinder to the house key, and set up user codes before we leave. Our smart lock installation page covers app and Wi-Fi setup in more detail.
How far is Ontario from your base?
Ontario is about 25 miles from our San Bernardino base, roughly 33 minutes in light traffic. Arrival time depends on traffic and on the job the technician is finishing, so we give you an estimate on the phone before you commit.
