Good to know

Good advice saves a visit sometimes and makes the next one shorter. We have written down what we tell homeowners, tenants, drivers and business owners when they ask what they should know, from key control to choosing hardware for a busy door.

Frequently asked questions

Lockout Services

My key snapped off in the lock. Is that still a lockout call?

It starts the same way and adds one step. The broken blade is removed with extraction tools that grip it and draw it out, rather than pushing it deeper, and then the door is opened normally. A key rarely breaks in a healthy cylinder, so the locksmith checks the pins and springs afterwards and cleans or services the cylinder if wear caused it. A new key is cut from the two halves or from the code, since a weakened copy would snap again. Home Lockout Service

Last night the door would not lock either. Is that the same problem?

Sometimes, though a deadlatch that will not catch at closing and a bolt that refuses to withdraw at opening are different mechanisms, not automatically the same fault. A door dropped on its pivots or a cam slipped behind the cylinder can affect either one; a closer stopping short of the strike explains a latch that will not catch but not a bolt that will not retract. The locksmith checks each symptom on its own during the visit and tests the door closing under its own weight before leaving. 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

Should I call the police before the locksmith?

Yes. Call the emergency number if there is any chance the intruder is still there, and the non-emergency line of your local police service otherwise. A break and enter is reported by phone rather than through the online forms used for minor property damage. Ask for the occurrence number, since your insurer will want it. Once the police have released the scene, or told you they are not attending, the locksmith can begin. Break-In Damage Lock Repair

Change or Rekey Locks

My deadbolt says I can rekey it myself with a little tool. Should I?

You can, given a key that currently operates the lock, the maker's reset tool, the new key and the steps followed in order. Trouble tends to arrive when the old key is missing, when the new key belongs to a different keyway, or when a reset stalls halfway and the cylinder then accepts neither key. A locksmith carries the tool and the procedure, can check that the new key suits the rest of your doors, and can fit a standard cylinder if a forced reset has broken the mechanism. Lock Rekeying

How long should the bolt be?

The bolt should extend at least 25 mm into the frame, which is the standard throw for a dwelling's entrance doors and the length most residential deadbolts provide. Part of the bolt stays inside the door for support while the rest sits in the pocket. A hardened steel insert that spins under a saw blade is a common feature worth having on doors that face a street or laneway. Deadbolt Installation

Can a lever replace a knob on the same door?

Yes, and it is a common change for anyone who finds a knob hard to grip. Levers use the same bore and backset as knobs, so the swap is usually a direct fit. Levers are handed, so the locksmith checks which way the door swings and chooses or adjusts the lever accordingly. A keyed entry lever pairs well with a deadbolt above it, and interior passage and privacy levers complete the set. Lock Replacement & Upgrade

Do I need to prove I own the house before you work on the lock?

Yes, and it is a normal part of any lock or key work. Photo identification together with something that ties you to the address is enough. If you rent, the locksmith will ask who should receive the keys, because landlords and tenants in this province are expected to agree on lock changes and share keys. This check takes a moment and it protects every household the locksmith is asked to work for. Vintage Mortise Lock Service

High Security Locks

Can you help with a safe found in an inherited or estate property with no records at all?

Yes. The locksmith identifies the safe directly from its hardware, brand plate if one survives, and physical layout, then proceeds with the same manipulation, decoding or reset options used on any safe with an unknown history. Documentation such as a will, an executor's letter or a property transfer establishes your authority to have it opened. Safe Opening & Combination Change

How do I know what rating of safe I actually need?

Start with what will be inside it. Cash, jewelry, and firearms mainly need protection from tools and time, so the burglary rating matters most. Paper records and digital backups mainly need protection from heat, so the fire rating matters most, and digital media needs a noticeably lower internal temperature than paper to survive. Many households and businesses end up choosing a unit built to both standards rather than picking just one. Safe Installation & Servicing

What does key control mean in practice?

It means your key can only be copied through the locksmith who manages your system, after checking that the person asking is on your list of authorised names. Blanks for the keyway are not sold to hardware stores or kiosks while the patent lasts. Each key is numbered and recorded, so you know how many exist. For a home that ends the worry about old copies; for a business it turns a lost staff key into a known, manageable event. High Security Locks

Commercial Locks

Will every old key stop working once you are done?

Every old key that operated a cylinder included in the plan will stop working, and the locksmith proves it by trying old keys at each door before leaving. Old keys keep working only at openings you chose to leave alone, which are written on the chart so there is no confusion. If a master key existed, it is tested too, since a forgotten master is the most common way an old key stays alive. Commercial Rekeying

How do you decide how many sub-master levels a business actually needs?

The number follows the organization, not a preference for tidy diagrams. Genuinely distinct groups, such as separate departments or floors with different access needs, each justify a level; access differences that exist only on paper usually do not. A hierarchy with more levels than the business uses in practice is harder to administer without making anyone's day-to-day access meaningfully better. Master Key System Design

Can a landlord and several tenants share one system?

Yes. In a multi-tenant building, a shared entrance can run on the landlord's controller while each tenant's suite runs its own credentials, so a tenant's staff can reach their own space without gaining access to another business's door. The property manager and each tenant work out together which doors belong on which list before the system is programmed. Access Control Installation

What should I have ready before the visit?

Knowing the intended use of the room, roughly how many people it holds, whether any doors are already fire-rated, and whether any of them are part of a pair helps the locksmith bring the right devices. If a fire inspector or building official has already given a note about the opening, having that note or its reference number on hand keeps the visit focused on what was actually flagged.

Car Keys

My car is in a gated lot or an underground garage. Does that matter?

Only for getting the van to the car. Tell the locksmith how the lot is entered, whether a code, a buzzer or an attendant is involved, and which level the car is on, so nobody loses time at the gate. In a tight garage the locksmith checks there is room to open the door fully and enough light to see the interior switches, and brings a torch if not. The opening itself is unchanged. Car Lockout Service

How long should I allow for the visit?

It depends on the starting point. Adding a spare to a car with a working key is often the shortest kind of visit. An all-keys-lost job on a newer vehicle takes longer, because the car has to be opened, the lock decoded, the immobilizer reset and any security timer waited out. Milling a high-security blade and pairing a proximity fob add their own steps. The locksmith gives you a realistic window once the VIN and the situation are known. Car Key Replacement

What should I bring to the appointment?

Bring the vehicle, its existing key, photo identification, and something that ties you to the vehicle: registration, or a document showing you are authorized to hold a key if the car belongs to someone else, such as an employer or a family member. Knowing the VIN in advance, printed or photographed from the door jamb, also helps the locksmith confirm the exact key system before arriving. Spare Car Key Duplication

Can you tell me which fob to buy before you arrive?

Often, yes, once the vehicle's identification number, model year and trim are known, since those details narrow down which fob part is actually compatible. Buying the wrong part number is a common reason a programming attempt goes nowhere, so confirming compatibility before ordering saves a returned part and a second visit. Key Fob Programming
