GTA Lockman Mobile Locksmith Services works on houses, townhomes, condo suites, businesses and vehicles across Whitby, from Port Whitby on the lake to downtown, north Whitby and Brooklin. The work comes to you in a fitted van, so most jobs are finished at the door: a lock changed or rekeyed, a sticking deadbolt repaired, a keypad lock fitted, or a car key cut and programmed beside the vehicle.
Whitby covers a lot of ground, and its housing changes a great deal from south to north. That shapes which lock problems turn up where, so this page walks through the town by area.
The streets around Brock and Dundas have some of Whitby's oldest homes, many with original or early wooden doors. Older doors bring their own lock issues:
The aim with older doors is usually to keep what works, repair what has worn, and strengthen the frame where the lock meets it.
Most of the newer homes in north Whitby and Brooklin were built with builder-supplied hardware: a knob or lever and a separate deadbolt, sometimes a keypad deadbolt on the front door, and often the same key across the house. Typical requests here:

Around the harbour and along the lake there are condo buildings and townhouse communities. In these, the suite or unit lock is usually the owner's responsibility, while the main entrances, mailroom, garage and amenity doors belong to the condominium corporation. Fobs are issued and deactivated by the management office.
If you are buying or have just moved into a condo, it is worth rekeying the suite door and checking which fobs exist. The full checklist is on buying a condo: suite locks, fobs and building rules. For a suite lockout, see apartment and condo lockouts.
Many Whitby households commute, and the house keys end up shared with grandparents, neighbours, caregivers, cleaners and dog walkers. Over a few years it becomes hard to say who holds one. A practical approach:
Shops, offices and units along Brock and Dundas, plazas across town and industrial units in south Whitby all use different hardware from homes: aluminium storefront doors with narrow-stile locks, steel rear doors, exit devices and master-keyed cylinders. Common jobs include rekeying after staff changes, repairing doors that will not lock at closing, and fitting latch guards on rear doors. See working with a commercial locksmith and commercial door will not lock at closing.

Car key replacement, fob programming and lockouts are handled at the vehicle, whether it is in a driveway, a workplace lot or a GO station parking lot. Have the VIN and ownership documents ready. See car key replacement and car lockout service.
Call or send a message with the address, the type of door or vehicle, and what has gone wrong. For a lockout, the technician will need to see identification and proof that you live at or are responsible for the property before opening the door. See proving you are entitled to enter.

Often. Older mortise locks can usually be repaired and rekeyed. Where a modern deadbolt is wanted, it is positioned around the existing lock pocket.
It is worth doing. Builder, trade and previous-owner keys may still be in circulation, and rekeying makes all of them stop working.
The condominium corporation controls the main entrances and fobs. The suite lock is usually the owner's responsibility.
