Good to know

Frozen cylinders open well with patience: lock de-icer or gentle warming melts the ice so the plug turns, and the cylinder is then dried and treated with a dry lubricant that sheds moisture. Hot water is avoided because it refreezes and can crack cold metal. To prevent a repeat, keep a storm door closed over the main lock, fit a keyhole cover on exposed side doors, and carry a small de-icer in your coat or car through the freeze-thaw months.

The opening is planned around it. Before any work, the person with the alarm code is ready to disarm, and where a monitoring company is involved they can be told to expect an entry at that address. If the contact trips anyway, the authorised person speaks to the station with the account password. Nothing about the alarm is bypassed; the door is opened, the system is disarmed normally, and the event is logged like any other.

Yes. Small cylinders in padlocks, mailboxes, desk drawers, filing cabinets and cam locks on lockers hold a fragment the same way a door does, and the same slim hooks and spirals fit them. Their keyways are narrower, so it is finer work. Where a padlock is not worth saving, the locksmith will say so and offer a cut-off and a new padlock keyed to your preference instead.

Sometimes, and the locksmith tests it honestly. A deadbolt that stayed thrown while the frame gave way may be undamaged, though a kick can bend the bolt where it crossed the gap or crack the housing. A cylinder that was twisted, drilled or punched is finished. Reused hardware must operate as smoothly as new with the door open and closed; if it hesitates, it is replaced, because a lock that took a blow tends to fail at the worst moment.

The key and cylinder are doing their job; the bar behind the cylinder that drives the bolt, called the tailpiece or cam, has broken, slipped or twisted out of engagement. It is a small part. The locksmith retracts the bolt through the mechanism or removes the cylinder to reach it, then fits a tailpiece of the right length and profile. Your cylinder and keys are unchanged afterwards.

An authorised adult should be present at the start, for identification and to agree the list of doors and the number of keys, and at the end, to test every key and take the count. In between, the work happens at the doors and on the van, so you are free to get on with your day inside. A property manager or a family member with your authorisation can stand in if you cannot be there.

A restricted or patented keyway is one whose blanks are not sold to the public, so copies can only be cut by an authorized dealer from a record of who is allowed to have them. Rekeying such a cylinder is the same operation inside, but the new keys are cut from controlled blanks and the count is logged. The benefit is that a key cannot be duplicated at a kiosk without your knowledge, which makes the record of who holds one much easier to trust.

You can, with a conversation first. Tenancy rules in this province expect a tenant to have the landlord's consent before changing locks and expect the landlord to hold a key, so ask in writing and share the plan. Many landlords welcome a proper bolt. The locksmith can key the new cylinder to the building's existing key where the keyway allows, and leave a note of the model and keys cut for the building manager.

The push is a sign the bolt and the strike pocket are out of line, which is a door and frame matter more than a lock fault. A new deadbolt is welcome if the old one is worn, but the visit also adjusts the strike, deepens the pocket or tightens hinges so the bolt throws freely with the door simply closed. Done together, the door locks with a fingertip and the new hardware works as designed.

Usually, yes. The mechanisms are simple and robust, and what fails is nearly always a spring, dried grease or wear on one part, all of which are repairable on a bench. Replacing the lock with a modern cylindrical set means boring a large hole through the door stile and filling the old pocket, which is more work and changes the door for good. A rebuilt case keeps the original trim and keeps the door intact.

Keep a thumb-turn, or a lever, on the inside of any door you might leave through. A door people use to exit the home works better opening from inside without a key, a code or special knowledge, which matters most in a hurry or in smoke. Smart deadbolts sold for houses have an interior turn as standard; the electronics sit beside it, not in place of it. Interior keypads belong on cupboards and safes, not on the way out.

The broken piece is removed with extraction tools shaped to grip and draw it out, rather than forcing it further in, and the door or gate is then opened using the remaining portion or by working the cylinder directly. Afterward the locksmith checks why the key broke, since a healthy cylinder rarely snaps a key on its own; a stiff or corroded plug is a common cause outdoors. A fresh key is cut from the code or a clean original rather than a worn copy.

Yes, and it is a common reason for this visit. Ownership or a lease showing the address, plus photo identification, is generally enough to confirm the compartment is yours to change. The old lock is opened without a key using the same techniques used elsewhere, then swapped for a new one, so whoever held the previous key no longer has any use for it.

Many electronic locks support more than one user code, so a manager and one or more backup employees can each be set up separately during the same visit rather than sharing a single combination. A mechanical dial only holds one combination at a time, so multiple access there means agreeing who holds it and how that changes when staff do.

A mechanical dial has no battery and is set by hand to a private combination, turning through a sequence to release the bolt; it never runs out of power but takes a little practice to open. An electronic keypad accepts a numeric code and can support several separate codes for different people, but it depends on a battery that eventually needs replacing. Many owners choose based on how many people need access rather than one being simply superior to the other.

Three things working together. The cylinder has a second locking mechanism, usually a sidebar released by finger pins or rotating pins, plus hardened steel in the path of a drill, so picking, bumping and drilling take far longer than on an ordinary lock. The deadbolt and strike are heavier and fastened into the framing. And the key is cut on a patented or restricted blank that only an authorised person can have copied. Remove any one and the door is weaker than the label suggests.

It depends on the count and the mix. A shop with a front door, a back door and a stockroom is a short visit; an office suite with a dozen lever sets, a master key plan and a mailbox takes a good part of a day. Interchangeable cores are the shortest of all, since they are swapped rather than repinned on site. The locksmith gives a time estimate at the assessment, once every cylinder has been counted.

A tenant's own hierarchy for their suite is designed and held separately from the building's shared systems, such as a condominium corporation's lobby or garage keying or a landlord's building-wide master. The two sit alongside each other rather than merging, so a tenant's private levels stay private while common areas continue to answer to whoever already manages them.

In most cases, yes. An access control installation can be planned to share information with an existing alarm panel, so an arm-or-disarm event lines up with whoever unlocked the door, and with a camera system, so a recorded clip can be matched to a specific credential rather than only a timestamp. The exact integration depends on what the existing alarm and camera equipment support.

Yes. An exit alarm module sounds when the device is used, which tells staff a door meant to stay closed has been opened, but it does not add any resistance to the push that releases the latch. The alarm is a notification layer on top of hardware that still opens under one motion, which is why it suits stockroom, dock or perimeter doors where entry through that opening should be rare.

A mortise lock has its whole mechanism, latch, deadbolt and sometimes a separate handle function, built into one case that sits inside a pocket cut into the door's edge. A cylindrical lockset is a bored-in unit, simpler to service, common on standard commercial and residential doors alike. Which one your door takes depends on how it was originally prepped, not on preference alone.

That is the ordinary case, and there is a routine for it. Tell the locksmith on the phone so the plan is agreed in advance. Often the plate can be matched to a photo of the permit on your phone, a family member can bring identification, or a fleet manager can confirm a company vehicle. Otherwise the door is opened and the documents in the glovebox are checked against your identification before the locksmith leaves.

A transponder is a small chip in the head of the key with no battery of its own. When the key is in the ignition, or the fob is inside the cabin, the immobilizer sends a signal and the chip answers with a code; if the code is unknown, the engine is prevented from running. Every new light vehicle sold in Canada since September 2007 has been required to have an immobilizer, so almost any car from that time on uses one.

Every door lock, the trunk or hatch, the ignition or start button, and any remote functions are checked with the new key on its own, apart from the original, so neither key is quietly helped along by the other's signal. The vehicle is started more than once to rule out an intermittent issue, and only once both keys pass independently is the visit considered finished.

This depends on the manufacturer, since each vehicle's memory has a set limit built in, commonly enough for several drivers plus a spare. The visit checks how many the specific vehicle allows and how many are already registered, so a household adding another driver knows whether there is room before a new fob is ordered.

Yes, though there is usually more to pair afterward: the proximity functions that let the vehicle detect the key nearby, alongside the same immobilizer identity a traditional transponder key would carry. The visit still ends with the same test, confirming the engine starts and the vehicle recognizes the key at a normal walking distance.

That is noted honestly before any work begins, since it often means an earlier attempt was made on the lock. Damage like this usually points toward a full cylinder and housing replacement rather than a simple service, because the internal parts of a lock that has already been forced are rarely trustworthy afterward. You are shown what was found before deciding how to proceed together.

A dead coin-cell battery is the most common reason, and it is a straightforward fix once the fob is opened. Less often, the fob has lost its pairing with the vehicle or its case has cracked and let in moisture, both of which a locksmith can check and address.

Each wafer represents one depth the key has to hit precisely for the lock to turn, so a lock with more wafers has more combinations and takes a little longer to decode or pick than a simpler one. Most motorcycle locks use around five wafers, and manufacturers sometimes space the depth increments further apart specifically to reduce the chance that an unrelated key happens to fit. This is why an ordinary-looking key rarely works in an unrelated bike.
