The seller, their agent and any tradesperson who held a copy are now locked out, and you carry a single key. Lock Rekeying

Plenty of houses in Markham still carry their first mortise locks and brass knobs, and they are worth keeping. We service that hardware so it turns freely again, find matching parts where they exist, and only suggest replacement when a piece genuinely cannot be brought back. Character stays; the door locks.

Markham
Locks on homes and businesses in Markham go through the same stages: they get installed, they wear, they need rekeying when people change, and eventually they are upgraded or replaced. The services here follow that life cycle so you can find the right one at whatever stage your door has reached.

Every square is one home in a hundred.
Yes. A tenant locked out of their own unit can arrange entry directly, and the identification check is the same: something that ties you to the address, such as a lease, a bill or a piece of mail, plus photo identification. Where you may want to involve your landlord is any change to the lock afterwards, because tenancy rules in this province expect landlords and tenants to agree on lock changes and to share keys. A locksmith can note what was done for the building manager.
Often the stiffness is grit, old oil and tired springs rather than real wear, and those are handled while the cylinder is on the bench: the plug is cleaned, new springs go in with the new pins, and a dry lubricant finishes it. If the plug has worn oval or the housing is damaged, the locksmith shows you and suggests a replacement cylinder pinned to the same key, rather than fresh pins in a lock that will keep dragging.
Well, with a little planning. Cold reduces battery capacity, so the locksmith fits fresh cells of the type the maker specifies and points you to the low-battery alert, and a new set before the first hard frost is a good habit. The bolt is aligned with clearance so a door that swells or shifts with freeze and thaw does not strain the motor. Keep ice off the keypad, and use lock de-icer only in the key cylinder, never on the touch surface.
Choosing corrosion-resistant fasteners and a cylinder rated for weather exposure at the outset avoids most of the problem, since plain steel fittings near a driveway or walkway take the brunt of de-icing salt over a winter. For hardware that already shows early corrosion, cleaning and a dry lubricant can extend its working life, while pitted or seized parts are better replaced than fought with season after season. A rinse of the hardware after a heavy salt application is a simple habit that helps as well.
