Lock Installation & Replacement in Oshawa

Rental turnover drives most lock work in north Oshawa. Houses around Ontario Tech and Durham College change hands every spring, and each turnover should mean new or rekeyed locks — owners in Oshawa's residential rental licensing zone are also keeping doors and hardware up to standard between inspections.

We swap deadbolts and entry sets like-for-like, upgrade to heavier-grade hardware, and fit locks to doors that were never bored for them — common in the older stock. Send a photo of the door edge and the existing hardware for a free quote; if you want keypad or smart locks across several rental units, we'll quote them keyed and coded as a batch.

Older Oshawa doors complicate a simple swap in predictable ways. Century homes near Parkwood often carry mortise locksets, where a modern cylindrical lock needs a filler plate or, better, a mortise-compatible replacement to avoid butchering an original door. The wartime bungalows have thinner slab doors and worn strike areas, so a new deadbolt often needs the jamb reinforced — longer strike screws into framing at minimum — to be worth the metal it's made of.

Oshawa's housing map still follows the auto industry that built it. South and central Oshawa are full of wartime and post-war homes put up for General Motors workers — compact bungalows and storey-and-a-halfs on generous lots, many now seventy-plus years old. Older prestige streets sit near Parkwood Estate and the downtown, while the middle of the city carries 60s-through-80s suburban stock. North Oshawa is the new chapter: Windfields and the Kedron lands have added thousands of homes since the 2010s, pulled along by Ontario Tech University and Durham College.

What you'll pay for lock installation & replacement in Oshawa depends on a few real things:

• Existing bores — standard-sized holes accept new hardware directly, while older or non-standard preps need adapting, and doors without a deadbolt need fresh drilling
• Door material — wood drills easily, steel doors need care to avoid tearing the skin, and fibreglass has its own rules; each changes the time per door
• Number of doors — securing a whole house in one visit is far more economical than door-by-door calls, especially keyed alike
• Door and frame condition — a sagging door or chewed strike area needs correcting first, or the new lock inherits the old lock's grinding death
• Hardware grade — residential locks span a wide quality range, and we'll explain what the grades mean for wear and forced-entry resistance before you buy
• Parking, access and any condo or townhouse rules at your Oshawa address, which affect how the crew works.
