The work may include assessing the opening, comparing compatible locksets or cylinders and installing the selected hardware with proper alignment.
The main decision factors are door and frame condition, desired function, keying, finish, user needs and whether existing holes can be reused.
Photos, door measurements when available, the number of openings and any request for matching keys. Sharing that information before dispatch helps the locksmith arrive with a more accurate picture of the request.
Replacement is not automatic; sound hardware may be repairable or rekeyable depending on the goal.
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.
