Deadbolt Installation

A single-cylinder deadbolt is the most common residential choice across Toronto neighbourhoods: a keyed exterior cylinder on one side, a thumb-turn on the interior. It's ideal for solid-core doors where no glass panels sit within arm's reach of the thumb-turn. Our technicians install these with precision boring when required, aligning strike plates to the door jamb's actual grain rather than shimming over a sloppy fit — a step that matters enormously for long-term security in older North York homes where door frames have shifted over decades.

A double-cylinder deadbolt requires a key on both sides, which prevents someone from breaking a nearby sidelight or transom window and reaching in to turn a thumb-turn. They're a legitimate security upgrade in the right context, but Ontario fire codes impose real constraints: building type, occupancy load, and egress requirements all factor in. Our trained technicians will tell you honestly whether a double-cylinder fits your situation or whether a better-fitting mortise lock or a jimmy-proof deadbolt rim lock is the smarter call for your specific door configuration.

A mortise lock is a different category of hardware entirely — a rectangular steel cassette that sits inside a pocket routed into the door edge, rather than a cylindrical bore through the face. Mortise lock installation is more involved than a standard deadbolt swap, but the payoff in security and longevity is substantial. Steel-door apartment entries in mid-rise buildings along Finch Avenue or Bathurst Street frequently call for mortise hardware because the door edge can accommodate the deeper pocket and because mortise assemblies resist torque attacks that can defeat a surface-mounted cylindrical lock. Our commercial locksmith team handles mortise lock fitting for businesses, multi-tenant residential buildings, and older Toronto homes with legacy door profiles.

Jimmy-proof deadbolt installation — sometimes called rim deadbolt installation — is a separate and often overlooked solution. These interlocking rim locks mount on the interior face of the door and interlock with a surface-mounted strike, making the bolt nearly impossible to spread by prying the door frame. They're common on steel apartment doors and older commercial entries where mortising the door edge isn't practical. If you've searched for jimmy-proof deadbolt installation options and aren't sure whether a rim lock or a mortise lock suits your door, a quick on-site assessment from our team will give you a definitive answer — call (437) 476-0564 and we'll schedule a visit around your timeline.

Residential deadbolt fitting in Toronto ranges from a straightforward grade-2 Kwikset or Schlage replacement on a pre-bored door to a full bore-and-fit on a new steel or fibreglass slab in a new-build where no prep holes exist yet. Our technicians carry hole saws, chisels, and installation jigs in the service vehicle so that every bore is centred, every strike plate is mortised flush, and every backset aligns with your existing door knob lock hardware — because a deadbolt that doesn't mate cleanly with the knob set below it is a security liability, not an asset.

For commercial locksmith work, the requirements step up considerably. Office suites in North York business parks, retail units along Yonge Street corridor, and warehouse facilities near the 401 each have different traffic volumes, key-control needs, and compliance considerations. We install grade-1 deadbolts, multi-point locking systems, and mortise lock bodies that accept restricted-keyway cylinders — meaning keys cannot be duplicated at a hardware kiosk. We can key multiple locks to a single master key system at the same visit, saving business owners significant coordination time. Before any commercial installation begins, we confirm an exact price that accounts for lock grade, door quantity, and any additional hardware such as escutcheons or door reinforcement plates.

Not every deadbolt call is planned. A tenant moves out and leaves with the only key, a door frame swells after a Toronto ice storm and the existing bolt no longer throws cleanly, or a forced entry attempt leaves the strike plate hanging from a single screw. Our emergency locksmith team operates 24/7 — midnight on a January night on a Willowdale side street is as covered as a weekday afternoon appointment in Forest Hill. When you call (437) 476-0564, a trained technician is dispatched from the North York area with hardware on board for single-cylinder, double-cylinder, rim, and mortise lock situations.

Damage-free installation is the standard we work to on every call where the door and frame are structurally sound. That means using the right jig for the bore, not hammering a strike plate over a cracked jamb, and reinforcing the frame when necessary rather than papering over a weakness. In cases where a door or frame is too compromised to hold a deadbolt securely, we'll tell you that plainly — and can advise on frame repair or door replacement options — rather than install hardware that won't actually protect you. Our goal is a result you won't have to call us back about.

Several practical factors shape the final price of any deadbolt installation job, and we walk through each one transparently before work starts. Lock grade and brand play a major role: a residential grade-2 single-cylinder unit sits at a very different price point than a grade-1 mortise lock body with a restricted cylinder. Whether existing bore holes match the new hardware, whether the strike plate pocket needs to be deepened, and whether a door knob lock needs to be replaced at the same time all add or reduce labour time. Time of day matters for after-hours emergency locksmith calls, and travel distance from our North York base to your address factors into the service call component. Parts needed — deadbolt, strike plate, reinforcement plate, escutcheon — are itemised clearly. The quote you receive before we touch the door is the price you pay.
