Small hardware, big inconvenience when it fails — a jammed mailbox lock means a trip to the post office you didn't plan for, and a broken cabinet lock can leave documents, medication, or valuables sitting unsecured in a home or office. Can-Lock Security services both across Ottawa, ON, and there's one important distinction worth understanding upfront before you call anyone.
Community Mailboxes vs. Private Mailboxes
Canada Post community mailboxes — the shared neighbourhood boxes found across most of Ottawa's newer subdivisions — belong to Canada Post. Their keys are stamped "Do Not Duplicate," and no locksmith, including us, has the authorization or parts to service or rekey them. A lost key or a jammed lock on a community mailbox has to go through Canada Post directly.
What we can service across Ottawa:
- Private mailboxes at single-family homes, common throughout the city's older neighbourhoods where individual post-mounted boxes are still the norm
- Apartment and condo mailbox banks, when authorized by the building owner or property manager
- Business mailbox panels
- Rural mailboxes, including replacing locks damaged by vandalism, which we see periodically on properties toward Ottawa's rural edges
If you're not sure which category applies to your situation, we're happy to take a look and point you the right direction even if the actual fix has to happen through Canada Post.
Common Private Mailbox Calls in Ottawa
- Lost keys with no spare, usually solved with a rekey
- Rusted or seized locks after a full Ottawa winter without lubrication
- Vandalism damage severe enough to need a full lock swap
- New homeowners wanting old keys retired for privacy after a property purchase
Cabinet Locks Across Homes and Offices
- Cam locks on filing cabinets, desk drawers, and display cases, common throughout Ottawa's home offices and small businesses
- Medicine cabinet locks, an increasingly common request from households with teenagers or visiting grandchildren
- Display case and glass cabinet locks, used by retail shops and homeowners securing collections
- Filing cabinet locks, both single-drawer and full-column
- Liquor cabinet and gun safe secondary locks, where an existing lock has failed or an upgrade is wanted
Rekeying to a Single Key
Ottawa offices and home offices alike often end up with a mismatched pile of cabinet keys accumulated over years of furniture purchases. We rekey multiple cabinet locks to a single key, or set up a keyed-alike system across a bank of filing cabinets — a common request from downtown offices and home-based businesses looking to simplify daily access.
Cam Lock Sizing Matters More Than People Expect
Cam locks come in different cylinder lengths to match panel thickness, and the cam itself needs correct orientation for the drawer or door it's engaging. A mismatched length either won't seat properly or will interfere with the drawer's movement — we carry a range of sizes specifically so a cabinet lock replacement in an Ottawa office or home doesn't turn into a second visit.
Government and Office Sector Considerations
Given Ottawa's concentration of government offices, professional services, and medical practices, cabinet and file lock security often intersects with real compliance requirements around securing records and documents. We're glad to walk through an office's filing setup and flag where a standard cam lock is sufficient versus where more resistant hardware makes sense.
Same-Day Service Across the City
Most mailbox and cabinet lock jobs across Ottawa are quick, same-day visits — rekeying, cylinder replacement, or new lock installation. We carry a wide selection of mailbox cylinders and cabinet hardware on our service vehicles.
