Tell your landlord or property manager as soon as the police have been called; provincial tenancy law makes the landlord responsible for repairs to the unit, and most will arrange the locksmith. A tenant may not change locks without the landlord's agreement, and a landlord who changes them must give the tenant keys, so the visit is coordinated between you. If you arrange securing yourself in an emergency, keep the receipt and the record of what was done for both sides.

Plan on an hour or two for a typical house with three or four cylinders, including the walk-through, identification, pinning, cutting and testing. Each additional cylinder adds a little, as does swapping a cylinder to bring a mismatched door onto the same key, resetting a homeowner-rekeyable lock or clearing a garage opener. The locksmith gives a realistic window on the phone once the list of doors is known.

Usually, yes. Most residential doors are prepared to standard sizes, a 54 millimetre cross bore and a backset of 60 or 70 millimetres, and most modern hardware adjusts between those backsets. The locksmith measures before choosing, so the new lock is matched to the door rather than the other way around. Where an older mortise lock or an unusual bore is found, filler plates, extension kits or a carefully jigged new bore bring the door to standard.

Rarely, and it is not the better route. Almost everything that fails is inside the case, and the case only opens once it is out of the pocket, which takes a few minutes and leaves no mark. Working through the keyhole with an unapproved or over-applied spray tends to wash out what little lubricant should stay and gums the levers later. Removing the case, cleaning it properly and refitting it is the repair that lasts.

Only if the model you choose uses one to reach the internet. Some locks have Wi-Fi built into the interior unit and connect straight to your router. Others save battery by using Bluetooth at the door and a small plug-in bridge nearby to relay to the network. Locks designed for a home hub join whatever hub you already run. The locksmith checks signal strength at the door itself and recommends the arrangement that keeps the lock reliably connected.

Both, where the two are connected, which on a gate they usually are. A locksmith working on a gate lock also looks at the hinges, the post and the closer, since a lock rarely fails on its own when the real cause is a sagging gate or a post that has shifted. Work that goes beyond hardware the locksmith carries, such as rebuilding a rotted post or a damaged fence panel, is flagged so it can be handled by whoever normally does that kind of repair.

You generally do not need to; identifying the hardware is part of the visit. The locksmith reads the maker's mark on the lock face, measures the cylinder and cam, and checks the hole pattern in the compartment door, which together point to a matching replacement even when the original brand is no longer sold.

It depends on the number of doors and levels involved. A small business with a handful of doors and one or two levels moves through assessment, pinning and testing in less time on site than a multi-floor property with several departments and a top-level master, where more doors, more testing and more keys to cut all add to the work involved.

In most cases, yes. Hooked and spiral extraction tools reach in and draw the broken piece out along the path it entered, rather than pushing it further in. Once it is clear, the cylinder is checked for the wear that likely caused the break in the first place, and a fresh key is cut to replace both broken pieces before the vehicle is handed back to you.
