Local context
West Vancouver includes waterfront apartments, hillside houses, townhomes and larger detached properties. That range is why the door, hardware and access situation must be described rather than inferred from the postal code.
For work in Ambleside, Dundarave, British Properties and Horseshoe Bay, the service address matters because parking, building access, strata entry and safe work space can change how the visit is organized.
Service scope
For this type of request, service generally means confirming the mailbox type and authority, removing the old cylinder and fitting a compatible replacement with new keys.
To avoid the wrong part or process, confirm whether the box is privately owned, part of a strata system or controlled by a postal provider or building manager.
Prepare for the visit
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.
