What commercial rekey service actually includes
Commercial Rekey Service sits inside the broader locksmith category, and the exact scope changes from one property to the next. A typical visit starts with an assessment: the professional confirms what you described over the phone, inspects the affected area, checks anything adjacent that could be contributing to the problem, and then confirms the plan and the price before starting. Skipping that step is the single most common reason homeowners feel surprised by an invoice later.
A complete commercial rekey service job normally covers labour, the standard materials or parts required, protection of the surrounding work area, removal of debris, and a functional test or visual inspection at the end. What is often excluded — and what you should confirm in writing — includes permits, disposal fees for bulky or hazardous material, specialty parts that must be ordered, work at height requiring extra equipment, and any repairs to finishes such as drywall, tile or paint once the main work is done.
Ask for the scope in writing even on small jobs. A one-page description that lists what will be done, what materials will be used, how long it should take, what happens if additional problems are discovered, and what is specifically not included will prevent almost every dispute that comes up on locksmith projects.
- On-site assessment and confirmation of the problem before work starts
- Labour, standard parts and materials for the described scope
- Protection of floors, furniture and adjacent finishes
- Cleanup, debris removal and a final functional check
- A written note of anything found that falls outside the original quote
How much does commercial rekey service cost in Ontario?
Most Ontario homeowners planning commercial rekey service budget within a typical range of $45 – $120 per lock, before HST, permits and any surprises found once work opens up. Ranges published online are planning figures compiled from Ontario market activity, not quotes. Two homes on the same street can receive very different prices for commercial rekey service because pricing follows the work in front of the professional, not the search term you typed.
The biggest cost drivers are scope and access. A straightforward job in an open, easy-to-reach area with modern materials sits at the low end of the range. Tight crawl spaces, finished basements, second and third storeys, older construction, obsolete parts, asbestos-era materials and anything requiring two people instead of one all push toward the high end. Emergency and after-hours calls typically add a premium, as do rural travel distances outside serviced areas.
Expect quotes to be structured one of three ways: a flat rate for a clearly defined job, an hourly rate plus materials for diagnostic or unpredictable work, or a per-unit rate where volume determines the total. Each is legitimate. What matters is that you know which one you are agreeing to, what the minimum call-out charge is, whether the diagnostic fee is credited against the work if you proceed, and whether HST is included in the figure you were quoted.
When you compare quotes, compare inclusions rather than totals. The cheapest number is often the least complete. A quote that excludes disposal, permits, restoration and a warranty is not cheaper — it is smaller, and the difference reappears later as a change order.
- Scope, size and complexity of the work
- Access, height, and how much has to be moved or protected
- Age of the property and availability of matching parts or materials
- Materials grade — builder standard versus mid-range versus premium
- Urgency: same-day, after-hours, weekend and holiday premiums
- Travel distance from the professional's service area
- Permits, inspections and disposal fees
- Season and demand — peak months cost more and book out further
How to get accurate commercial rekey service quotes without wasting time
The quality of a quote depends almost entirely on the quality of the information you give. Before you request pricing for commercial rekey service, take three or four photos of the area from different distances, note the approximate age of the home, measure anything obviously measurable, and write down when the issue started and what you have already tried. That five-minute exercise is the difference between a real number and "we'll have to come look."
Get at least two or three quotes for anything beyond a minor service call, and try to get them within the same week so you are comparing the same market conditions. Ask each professional the same questions in the same order. If one quote is dramatically lower than the others, that is information — ask what is excluded rather than assuming you found a bargain.
Through ProsFix.ca you describe the job once and we route it to local professionals who cover your address and take on this type of work. You are not obligated to hire anyone, and there is no charge to homeowners for being matched. You can also call (833) 659-7592 and describe the job over the phone if you would rather not type it out.
How long does commercial rekey service take, and how soon can someone come?
Scheduling for locksmith work in Ontario follows a predictable pattern. Genuine emergencies — anything involving active water, no heat in winter, no power, or an immediate safety risk — are usually attended within hours by companies that offer emergency dispatch, at a premium rate. Routine work is typically booked within a few days to two weeks. Larger planned projects and anything requiring ordered materials or a permit run longer, and in peak season the wait can extend to several weeks.
On-site duration is separate from lead time. Many commercial rekey service jobs are completed in a single visit of a few hours. Others need two visits: one to diagnose and order parts or materials, and a second to complete the work. Projects that touch multiple trades require sequencing, and each handoff adds a day or two even when everyone is efficient.
If timing matters, say so up front and ask for it in writing: the start date, the expected number of working days, and what happens if the schedule slips. Ask whether the crew works consecutive days or splits time across sites, because that single detail explains most of the frustration homeowners report on longer projects.

How to choose the right professional for commercial rekey service
Credentials come first. Confirm the business is registered, carries commercial general liability insurance, and carries WSIB coverage or a valid independent-operator clearance. Ask for certificate numbers, not verbal assurance, and confirm that any trade licence covers the specific work you need rather than something adjacent to it.
Then look at fit. Someone who does commercial rekey service every week in properties like yours will diagnose faster, price more accurately and finish more cleanly than a generalist who takes the job occasionally. Ask how many similar jobs they have completed in the last year, whether they have worked on homes of your era, and whether they can show recent photos or references from your area.
Finally, look at how they communicate. Professionals who answer clearly before you have paid them anything tend to keep doing so afterwards. Vague answers, refusal to put scope in writing, and pressure to decide immediately are all reasons to keep looking. There is always another qualified professional.
- Business registration, liability insurance and WSIB coverage confirmed by number
- Trade licence or certification appropriate to the specific work
- Recent, verifiable experience with this exact type of job
- Written scope, price structure and payment schedule before work starts
- A stated warranty on workmanship in addition to any manufacturer warranty
- Clear, prompt communication and no pressure to sign on the spot
Questions to ask before you hire for commercial rekey service
Use the same short list with every professional you speak to. Consistent questions produce comparable answers, and comparable answers make the decision obvious. Write the responses down — a month later you will not remember who said what.
- Is the quote for commercial rekey service a fixed price or an estimate, and what would change it?
- Does the price include HST, disposal, permits and restoration of finishes?
- Who will actually be on site — employees, or subcontractors?
- What warranty applies to labour, and how long does it last?
- What is the deposit, and what is the payment schedule?
- What happens if you find additional problems once work starts?
- Can you provide proof of insurance and WSIB clearance?
- How much notice do you need to reschedule, and are there fees?
Permits, codes and regulated work in Ontario
Whether commercial rekey service requires a permit depends on the specific work and your municipality. Repairs and like-for-like replacements are frequently exempt, while structural changes, new circuits, gas connections, plumbing rough-ins, and anything altering the building envelope commonly require a permit and inspection.
Permits protect you more than they protect anyone else. Unpermitted work can complicate an insurance claim, surface during a home inspection when you sell, and in some cases must be opened up and redone at your expense. If a professional suggests skipping a permit that is clearly required, treat it as a disqualifying answer.
Ontario also regulates certain trades directly. Electrical work is governed by the Ontario Electrical Safety Code and administered by the ESA; gas work must be performed by a TSSA-certified technician; and several trades are compulsory under Skilled Trades Ontario. Ask which regime applies to your job and get the licence number.

Should you DIY commercial rekey service or hire a professional?
Some parts of commercial rekey service are genuinely homeowner-friendly: preparation, clearing access, minor maintenance and cosmetic finishing. Doing that work yourself can reduce labour hours and is worth discussing with the professional in advance so it is reflected in the quote rather than duplicated.
The work to hand over is anything involving electricity, gas, structure, water under pressure, working at height, or a permit. The tools are expensive to rent, the failure modes are costly, and a mistake in a regulated trade can void insurance coverage. The savings on a single DIY attempt rarely survive one bad outcome.
A reasonable middle path is to hire out the regulated or high-risk portion and handle the low-risk surrounding tasks yourself. Say that plainly when you request quotes so the professionals price the split scope accurately instead of assuming a full-service job.
Seasonal timing and Ontario conditions
Ontario's climate shapes both pricing and availability for locksmith work. Demand spikes in the first cold snap and the first hot week of summer, and again in the spring rush from April through June. Booking outside those windows generally means shorter waits, more attentive scheduling and occasionally better pricing, because contractors are filling gaps rather than triaging a queue.
Weather affects the work itself, not just the calendar. Freeze-thaw cycles, road salt, heavy snow loads, spring runoff, summer humidity and Ontario's swings between -25°C and +32°C all influence material choices and how long a repair lasts. A professional who works here year-round will specify accordingly; one who does not may install something that fails by the second winter.
If your commercial rekey service project is not urgent, plan it during a shoulder season. Late winter and early autumn are consistently the easiest times to get a good local professional to give your job full attention.
Common mistakes that cost homeowners money
Most bad outcomes on locksmith projects trace back to a handful of avoidable decisions rather than bad luck. The list below covers the ones we see most often in Ontario.
Take particular care with deposits. A modest deposit to cover ordered materials is normal; a large up-front payment before any work begins is not, and it is the most common way homeowners lose money.
- Hiring on price alone without comparing what each quote includes
- Accepting a verbal scope instead of a written one
- Paying a large deposit in cash before any work starts
- Not confirming insurance and WSIB coverage
- Skipping a permit that the municipality requires
- Approving change orders verbally while work is underway
- Making final payment before the completion walkthrough
- Failing to keep invoices, warranties and permit records for resale

Maintenance and getting the longest life out of the work
Once commercial rekey service is complete, ask the professional two questions: what maintenance keeps this performing, and what early warning signs mean you should call again. Write the answers down and put a recurring reminder in your calendar. Most premature failures in locksmith work come from a small, cheap maintenance task that nobody was told about.
Keep the paperwork together — final invoice, warranty terms, permit and inspection records, product model numbers and photos of the work before anything was closed up. That file is genuinely valuable when you sell, when you make an insurance claim, and when a different professional needs to understand what is behind the wall.
A short annual inspection is inexpensive compared to reactive repair. If you have a professional you trust after this project, ask whether they offer a maintenance visit or a priority service arrangement for returning customers.

Choosing a professional who already works in your municipality means faster response, familiarity with the local permit office and inspectors, and lower travel costs baked into the price. It also means the references you ask for are checkable, and the work is nearby if a warranty callback is needed.
