The work may include confirming the mailbox type and authority, removing the old cylinder and fitting a compatible replacement with new keys.
The main decision factors are whether the box is privately owned, part of a strata system or controlled by a postal provider or building manager.
Identification, proof of address or authorization and confirmation of who owns and manages the mailbox. Sharing that information before dispatch helps the locksmith arrive with a more accurate picture of the request.
Some community or postal mailboxes must be serviced by the property manager or postal provider rather than a private locksmith.
For work in Metrotown, Brentwood, Edmonds and Burnaby Heights, the service address matters because parking, building access, strata entry and safe work space can change how the visit is organized.
Burnaby's mix of high-rise, mixed-use and detached properties makes diagnosis more useful than assuming the same lockset or access method everywhere.
Before the visit ends, test the lock or key in its normal Burnaby setting and give new keys, codes or credentials to the person responsible for them.
