Vaughan runs from big-box strips to office parks and estate pockets. When keys do not come back after a termination, you need a clear plan: rekey cylinders, adjust a master hierarchy, or swap hardware. Mobile service can cover after-hours openings if you coordinate access rules up front.

1. Rekeying after a single departure versus a pattern
One lost key might mean one cylinder. A pattern of turnover usually means it is time to audit who has which sub-master. We ask for a simple map: which doors must stay separate from which - that keeps pricing aligned with reality.
2. Storefront cylinders versus exit devices
Retail often mixes display doors with exit hardware in back corridors. They are not interchangeable jobs - photos and brand names help us quote before we roll.
3. After-hours fobs and loading docks
Tell dispatch if security must escort, if docks roll shut at a set hour, or if only one supervisor can approve scope changes. Commercial surprises on site usually mean access rules were underspecified on the call.
Our mobile locksmiths serve the entire GTA. Call (647) 874-2137 for current availability.
4. Master-key systems: what not to break
Changing one core without understanding the grand master can lock out a whole wing. If another vendor designed the system, share whatever paperwork exists - we still verify on site before turning a screwdriver.
5. When to pair commercial work with residential rekeys
Owners sometimes want the house rekeyed the same week as the shop. Mention both on the first call - we can schedule two stops if timing allows.
