How it works
Mailbox locks are small cam locks, and they fail in predictable ways. Keys wear, cams seize, and new residents inherit no key at all. Urban Locksmith replaces mailbox and cabinet cam locks across Ottawa for private boxes and multi-unit buildings.

- Step 3

- Step 4
Keys issued
Numbered and recorded for multi-unit boxes.
Community boxes versus private mailboxes
Canada Post community mailbox locks are Canada Post property. Consequently a locksmith cannot legally change them, and you must contact Canada Post directly. By contrast, a private mailbox on your own wall or a lobby box owned by a building are both fair game. Therefore the first question is always who owns the box. Naturally we tell you if it is not ours to touch.
How cam locks work
A cam lock is a small cylinder with a flat metal arm that rotates to latch. Consequently they are simple, cheap and easy to replace. However, cam length and rotation direction both matter, because the arm must reach the catch. Furthermore, the mounting hole diameter varies. Therefore Urban Locksmith measures before ordering rather than assuming a standard size.

Often, if the hardware supports it.
Multi-unit lobby boxes
Buildings with lobby mailboxes usually need locks changed at tenant turnover. Consequently doing several at once is far cheaper than one at a time. Moreover keying them differently is essential, because a shared key defeats the purpose entirely. Therefore we number and record each lock against its box. Additionally, a master for building management can be arranged if the hardware allows.
Cabinet and furniture locks too
The same cam locks appear in desks, filing cabinets, display cases and lockers. Consequently the work is identical. Furthermore, many older cabinets have long-lost keys, and the lock can usually be picked or the code read rather than drilled. Therefore Urban Locksmith opens and rekeys cabinet locks rather than destroying them wherever the hardware allows.

No. Those belong to Canada Post, so you must contact them directly.
What about a lobby mailbox in my building?
Yes, with authorisation from the building owner or manager.
Can you open a cabinet with no key?
