A manager at a Harvester Road flex unit discovers an employee left last Friday without returning a key fob and a physical key. The building has six staff members. She does not know how many copies were made over the past two years. That is not an uncommon Tuesday morning call.
Treco Locksmith & Security handles the commercial and light-industrial side of Burlington and Hamilton, rekeying after staff exits, building master key systems from scratch, installing access control on doors that currently run on a handshake and a prayer, and getting businesses back open after a lockout at any hour. We have been mobile-only since 2018, which means we bring the shop to you: no storefront, no waiting for a parts order.

Commercial Services in Detail
Master Key Systems
A master key system creates a working hierarchy of access. The owner or general manager carries a master key that opens every lock on the property. Each employee or department carries a change key, a restricted key cut to open only the doors relevant to their role. A grand master key can sit above the whole system if you manage multiple buildings or suites.
The practical effect: the accounting manager can access accounting and common areas but not the server room. The server room technician cannot open payroll storage. You do not hand out one key to everyone and hope for the best.
We design, key, and install master key systems for single suites through to multi-building property portfolios. The planning stage matters, a poorly designed keyway hierarchy is expensive to undo, so we walk through your floor plan and access requirements before cutting a single key.
Rekeying for Staff Turnover and Tenant Changes
Rekeying changes the pin stack inside an existing lock cylinder so the old key stops working. The hardware stays; only the internals change. It costs less than replacing locks and takes minutes per cylinder.
It is the standard move for:
- Staff departures, especially if the key was not returned or you are unsure about copies
- Tenant changeover, between lease terms on a retail unit or office suite
- Lost or stolen keys, before a potential misuse, not after
- Post-break-in review, when a full security audit makes sense
We can rekey a single door or an entire floor in one visit.
Access Control and Electronic Hardware
Not every door needs a physical key. Standalone keypad deadbolts work well for back-of-house access, storage areas, or server closets where you want a PIN instead of managing keys. Multi-door card-access systems let you assign and revoke credentials from a dashboard without ever touching a lock.
We supply and install electronic access control at both ends of that range: simple keypad locks for small offices, and multi-reader commercial systems for larger facilities. Credentials can be PIN, proximity card, key fob, or mobile device, depending on your traffic and your tolerance for managing hardware.
High-Security Hardware and Restricted Keys
Standard locks sold at a hardware store can be pinned open with a bump key or picked with basic tools. High-security locks, brands like Medeco, Mul-T-Lock, and ASSA Abloy’s restricted lines, use patented keyways, hardened steel inserts, and anti-pick pin configurations that defeat most casual attacks. More importantly, the keys are patent-controlled: a hardware store cannot duplicate them. Only an authorised dealer can cut a new key, and the transaction is logged.
If you run a business where key control matters, a pharmacy, a financial office, a data centre, a building with high staff turnover, the upgrade pays for itself the first time you avoid a re-key or a break-in.
Panic Bars, Exit Devices, and Door Closers
Commercial exit doors on designated egress paths are typically required to have panic hardware: the push bar releases the latch from inside without any special knowledge or a key. Fire-rated exit devices add a latch-every-close requirement so the door cannot be propped open, which matters for fire separation walls.
We supply and install ANSI/BHMA Grade 1 exit devices, the rating used for high-traffic commercial applications, including fire-rated units meeting CAN/ULC-S104 and CAN/ULC-S132 standards. We also replace door closers that are no longer holding a door shut properly or are dragging and failing.
Commercial Lockouts & After-Hours
A broken key in the lock first thing in the morning. A latch that fails the night before inventory. A staff member who locked the only set of keys inside. We handle commercial lockouts and keep after-hours call-out available across the area. Call (905) 977-8476 and we will tell you exactly when to expect us.
For emergency locksmith situations that go beyond the door, a break-in, a failed lock after a forced entry attempt, we carry replacement hardware on the van so you are not left with an unsecured building.
Business Types We Serve
Office buildings and professional suites need key control between departments and reliable after-hours access. Master key systems and access control are the standard solution. We work with single-tenant office buildings and multi-tenant suites along Burlington’s North Service Road corridor and in Hamilton’s downtown King Street and Main Street office market.
Retail plazas and storefronts turn over tenants, deal with after-hours lockouts, and often have legacy hardware that was never updated between leases. A rekeying visit between tenants is the minimum; often it is worth upgrading the lock grade at the same time.
Industrial and light-manufacturing facilities have loading bays, exterior pedestrian doors, and sometimes office pods inside a large floor plate. Hamilton’s Bayfront Industrial Area, the manufacturing and steel corridor between Hamilton Harbour and Barton Street, and the industrial parks along Stoney Creek’s Barton Street East both have the kind of high-traffic, shift-change environment where key control gaps accumulate fast. We handle master key planning and hardware installation for that environment.
Property managers dealing with unit turnover across Burlington, Hamilton, Oakville, and surrounding areas call us regularly between tenancies. We coordinate re-keying schedules, update master key records, and handle the odd mid-night lockout call.
Restaurants, hospitality, and service businesses have back-of-house access needs, staff turnover that runs hot, and doors that take a beating. We install hardware rated for that volume.
What Drives the Cost
No two commercial jobs are identical, so we do not publish flat rates. The main variables are:
- Number of doors and cylinders, a 3-door office and a 30-door facility are different conversations
- Hardware grade, ANSI/BHMA Grade 1 commercial hardware costs more than Grade 3 residential, for good reason; it is built for hundreds of thousands of cycles
- System complexity, a single master key over six identical cylinders is straightforward; a grand master with three sub-master groups across two buildings requires planning time
- Electronic vs mechanical, access control hardware, cabling, and software licensing carry separate costs from standard cylinder locks
We quote on-site after walking the job. There are no surprises after the fact.
Serving Burlington, Hamilton, and the Surrounding Area
We cover the full Halton and Hamilton region: Burlington, Hamilton, Oakville, Stoney Creek, Brantford, Grimsby, and Caledonia.
Burlington’s QEW-adjacent business parks, from the flex units at Harvester Road to the industrial strip along North Service Road, are a regular part of our service area. So is Hamilton’s industrial north end: the bayfront steel corridor, the Barton Street East commercial strip, and the mid-city office towers along King and Main. Wherever your business is, we are already familiar with the terrain.
