Advice from the van

Think of these notes as the conversation we would have while packing up the tools. What to keep an eye on, what a rekey actually does, why the spare key under the mat is a bad plan, and how to keep a car key from becoming a problem.

Questions we hear most

Lockout Services

I rent my place. Can I call a locksmith myself?

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. Home Lockout Service

The key snapped off inside the lock. What happens now?

The broken blade is removed with extractors that grip it and draw it out toward the face, then the cylinder is opened normally. Keys rarely break in a healthy lock, so the cylinder is cleaned, the cam behind it checked for stiffness, and a dry lubricant applied. A new key is cut from the code or from the two pieces rather than from a worn spare, since a tired copy is usually what broke. Business Lockout Service

Why did my key break at all?

Often fatigue, though not the only cause. A brass blade is weakest where the deepest cut leaves the least metal, and thousands of turns can slowly work a crack into that spot. Then one morning something asks more of it: a frozen cylinder, a bolt binding in a swollen door, grit in the keyway, or turning before the key was fully in. A bent, worn or poorly cut key can also fail on its own, with no such trigger. The lock is inspected afterwards to find which applied. Broken Key Extraction

Will my door be boarded up, or can it be made to lock tonight?

Most forced doors lock again during the visit. If the slab and frame are sound, a new lockset goes in and the strike is reinforced. If the jamb is split, a repair plate or a boxed strike screwed into the stud usually holds it. Boarding is reserved for openings where the frame or the door itself is destroyed, and even then it is fitted so the household can get out from inside without a key. Break-In Damage Lock Repair

Change or Rekey Locks

My house is older and has a mortise lock. Can that be rekeyed?

Yes. A mortise lock, the kind with a large case set into the edge of the door, uses a threaded cylinder held by a set screw reached from the door's edge. The cylinder unthreads, is pinned like any other and screws back in. Where a very old lock uses a bit key or a lever mechanism instead of a pin cylinder, the locksmith will explain the options, which may include fitting a modern cylinder into the existing case so the door keeps its original hardware. Lock Rekeying

What should I have ready before the locksmith arrives?

Know which doors you want bolted, what they are made of, and whether each already has a deadbolt or only a knob. A photo of the door face and edge helps. Have any existing keys to hand, decide whether you want everything on one key, and mention glass near the lock, a storm door in the same opening, or a rental agreement. If you have already bought hardware, keep the box and template together. Deadbolt Installation

How do I look after a new lock so it stays smooth?

Very little is needed. Whatever lubricant and interval the cylinder maker specifies, worked into the keyway with a few turns of the key, keeps the pins free; using the wrong product collects grit instead of helping. Wipe salt off exterior hardware during winter melts. Snug the hinge and strike screws each spring and fall as the door moves with humidity. Cut spare keys from a crisp original rather than a worn copy. Lock Replacement & Upgrade

Will the door look any different afterwards?

Usually not, when the original case is repaired: the same knobs, escutcheons, faceplate and strike go back on in the same positions, and the only visible change is paint or grime cleared from the edges that were catching. A replacement case is chosen to match the pocket so original trim is reused wherever spacing allows, though an occasional case needs a small pocket or fixing change, explained beforehand.

High Security Locks

My safe was in a fire or a flood. Does that change how it gets opened?

It can. Heat or water exposure sometimes trips a relocker or damages the bolt work independently of the combination lock, so the locksmith checks for that first rather than assuming the lock itself has failed. A safe with fire-rated insulation may also need that lining checked once open, separately from the lock work. Safe Opening & Combination Change

What does a typical installation or servicing visit involve?

The visit opens with a look at what the safe needs to protect and where it will sit, moves into positioning and anchoring for a new unit or bolt-work and lock testing for an existing one, and ends with the lock cycled several times and a combination or code set that only the owner knows. The exact order shifts depending on whether the job is a new installation or ongoing servicing. Safe Installation & Servicing

Do high security locks need special maintenance?

Only light care. Use the dry lubricant the locksmith recommends once or twice a year, never oil, which gathers grit around the finger pins and sidebar. Keep the keyway free of debris and insert the key fully before turning. In winter, warm a resisting key in your hand or use a de-icer rather than forcing it. Check hinge and strike screws each season so the door stays aligned. Treated this way the cylinder lasts for decades. High Security Locks

Commercial Locks

Does stamping keys 'do not duplicate' stop people copying them?

Not reliably. The stamp is a request, and any key on a standard blank can be copied by anyone with the blank and a machine. What does work is controlling the blank itself through a restricted keyway, or controlling access to the lock through interchangeable cores and a tight register. Stamping still has a place: a serial code on each key, instead of the business name, lets you track it without telling a finder where it fits. Commercial Rekeying

Can different lock brands be mixed in one master key system?

Sometimes, but it depends on the keyway and pinning platform each brand uses; some are compatible with one another and some are not. Where a mix already exists on a property, the assessment identifies which cylinders can be brought into a single hierarchy and which need replacing with a matching platform so every level pins correctly across the whole set of doors. Master Key System Design

What's the difference between an electric strike and a magnetic lock?

An electric strike fits into the existing door frame and works with the door's own latch or bolt, releasing it briefly for a valid credential while otherwise behaving like an ordinary strike plate. A magnetic lock instead clamps the door shut with an electromagnet mounted at the head of the frame, and it is always installed with a request-to-exit device so someone leaving is never held up looking for a way out. Access Control Installation

What happens with a pair of doors instead of one?

It depends on the pair. Some latch independently and need nothing extra. Where the hardware calls for a set closing order, a coordinator lets the two leaves close in the right sequence, letting the active leaf's device seat properly into a strike carried on the inactive leaf, or into an astragal. Alternatively, the centre mullion can be removed and a vertical-rod device fitted to each leaf, turning the pair into one wide exit. Whichever applies, both leaves are tested working together, not one at a time. Panic & Exit Hardware

Car Keys

Can you open a pickup, a motorcycle, a trailer or a motorhome?

Yes. Trucks and vans often have a separate cargo or tailgate lock, motorhomes use household-style cylinders on their living-space doors, trailers and hitch locks are padlock-type hardware, and motorcycle seat and steering locks are small wafer cylinders. Say what the vehicle is when you call so the right picks and blanks are in the van, and expect the same authorisation check for each. Car Lockout Service

Which documents count as proof of ownership?

Government photo identification plus the vehicle permit issued by ServiceOntario, the green ownership showing the VIN, is the usual pair. An insurance slip or a lease agreement in your name also works. For a company vehicle, a work order or letter from the fleet manager naming the VIN covers it. If you bought the car days ago, bring the bill of sale and the signed permit until the transfer is done. Car Key Replacement

Can a spare be made from a key that is already worn?

Yes, and it is often a good reason to make one. Rather than tracing every rounded edge of a worn blade onto the new copy, the locksmith can decode the lock or cut to a valid factory code for the blade, then read or clone the chip data separately for the electronics, producing a spare that is cleaner than the original rather than a copy of its wear. The worn key can then be compared against the fresh one and retired if it is due for that. Spare Car Key Duplication

Why do my fob's buttons work but the car still won't start?

This usually points to two separate systems handling two separate jobs: the remote's buttons operate the locks and alarm over radio, while a hidden chip in the fob authorizes the engine to start once it is recognized inside the vehicle. When one half is registered and the other isn't, or a chip has failed, the buttons keep working while starting authorization does not. Key Fob Programming
