GTA Lockman provides mobile locksmith services throughout Markham for residential, commercial, and automotive jobs. Our technicians travel to your location with a fully stocked van, allowing most work to be completed on-site in a single visit. Whether you need a lock change in Unionville, a car key replacement near Markham Town Centre, or a master key system for a commercial property in the Cornell Business Park, we confirm a flat-rate price before sending a technician.
Markham is a large and varied city in York Region, with a mix of established residential neighbourhoods, newer planned communities, and one of the most significant concentrations of technology and business campuses in the GTA. Our coverage includes all of Markham’s communities, from Unionville and Milliken in the south and west to Cornell, Boxgrove, Wismer, and Swan Lake in the east and north. When you call, we confirm your address and schedule accordingly.
Every GTA Lockman technician serving Markham holds a valid Ontario locksmith licence, has completed a police background clearance, and carries full bonding and liability insurance. Credentials are available for inspection before any work begins on your property or vehicle, on every job regardless of size or service type.
Monday to Thursday 8:30 AM to 9:00 PM. Friday 8:30 AM to 4:00 PM. Sunday 9:30 AM to 9:00 PM. Saturday closed. Call (647) 955-3277 to confirm availability and book a visit.
Markham’s residential landscape includes older detached homes in established areas like Unionville and Milliken, mid-age townhouse and semi-detached communities throughout Raymerville, Markville, and Berczy Village, and newer builds in Cornell, Wismer, and Swan Lake. Each property type brings its own mix of lock hardware, and our technicians work with all of it — from older mortise locks on heritage homes in Old Unionville to modern electronic deadbolts on new builds.
The most common residential requests we handle in Markham are lock rekeying after a tenancy change or key loss, full lock replacements when hardware has worn or been forced, and deadbolt upgrades on doors that have only a latch or a lower-grade cylinder. Rekeying adjusts the internal pins of an existing lock so that only a new key works, invalidating any copies previously cut. Where the hardware itself needs replacing, our technician carries a selection of residential lock grades and can fit the right option on the same visit.
We also install smart and electronic locks for homeowners who prefer keypad or app-controlled entry. These are popular in Markham households managing short-term rental units, frequent contractor access, or simply wanting to eliminate the need for a physical key. Full installation, device pairing, and user code setup are completed on-site. Other regular requests include mailbox lock replacements, new lock installations on side entries and garage doors, lock repairs on sticking or misaligned hardware, and broken key extraction when a key has snapped inside a cylinder.
Replace existing hardware with a new lock of the same or a higher grade. Suitable after forced entry, hardware failure, or when a security upgrade is needed on a specific door.
Adjust the cylinder pins to match a new key while keeping the existing hardware in place. The right choice after moving into a new property or following a key loss.
Full installation and configuration of keypad, Bluetooth, and Wi-Fi enabled locks. User code programming and device pairing completed during the same visit.
Our automotive technicians carry key cutting and programming equipment for most vehicle makes and models. All automotive jobs are completed at your Markham location, with no towing or dealership visit required.
We produce a replacement key from scratch using lock decoding and VIN-based key code lookup. No original key is needed. Proof of vehicle ownership is required before work begins.
Transponder chip keys and remote fobs are programmed to your vehicle’s immobiliser on-site. We cover most makes including Toyota, Honda, Ford, GM, Hyundai, Kia, Nissan, and European models.
Having a programmed spare reduces the cost and disruption of a full replacement if the original is ever lost. We cut and programme duplicate keys at your Markham location.
A worn ignition cylinder can prevent a key from turning or cause it to become stuck. We diagnose and repair or replace ignition cylinders for most vehicle makes at your location.
When keys are locked inside a vehicle, our technicians use non-destructive entry methods to restore access without damage to door seals, windows, or the locking mechanism.
After a key loss or a used vehicle purchase, we clear all previously registered keys from the immobiliser and programme a fresh set, removing residual access from any keys no longer in your possession.
Markham is home to one of the largest technology and corporate employment zones in Canada, including the Markham Centre corridor, the IBM Canada campus, the Markham Stouffville Hospital precinct, and significant retail and industrial activity along Highway 7, Woodbine Avenue, Warden Avenue, and Steeles Avenue East. GTA Lockman works with businesses across all of these areas, providing locksmith services that fit around operating schedules and are priced at a flat rate before any work begins.
One of the most commonly requested commercial services in Markham is the design and installation of a master key system. This allows a business owner or building manager to carry a single key that opens multiple doors while keeping individual offices, storage areas, or units on separate restricted keys. It is well suited to the multi-tenant office buildings and mixed-use developments that are common throughout Markham’s corporate and retail zones. Our team assesses the existing hardware, designs the key hierarchy, and carries out the installation during a scheduled visit.
We also install high-security cylinders for businesses with sensitive inventory or data, panic bar and exit device hardware for buildings requiring code-compliant egress, and electric strike systems for controlled-access entry points. For property managers overseeing residential and commercial portfolios in Markham, we offer ongoing locksmith support including lock changes between tenancies, rekeying, and access control updates. Details on how we work with management clients are available on our property management locksmith page.
All GTA Lockman technicians carry their Ontario locksmith licence and police clearance documentation. The authorising contact on any commercial job can request to see these before work begins on the premises.

The right choice depends on the condition and grade of your existing hardware. Rekeying adjusts the internal pins of the current cylinder so only a fresh key works, invalidating any copies the previous owners may have kept. It is cost-effective when the hardware is in good condition and the lock grade suits the door. A full lock replacement makes more sense when the hardware is worn, the grade is lower than you would prefer, or you want to take the opportunity to upgrade to a higher-security cylinder or a smart lock. Our technician can assess each door when they arrive and give you a clear recommendation before any work begins.
Yes. Our automotive technicians carry the cutting and programming equipment needed for most vehicle makes and models. We use lock decoding and VIN-based key code lookup to produce the correct blade without the original key, then programme the transponder chip or remote fob to your vehicle’s immobiliser at your Markham location. Proof of ownership is required before work begins. Call with the vehicle make, model, and year and we will confirm an accurate price before the visit is scheduled. Our pricing is generally well below what dealerships charge for the same service.
We confirm the price for your specific job before a technician is sent to your Markham location. There are no call-out fees, no travel surcharges, and no charge for the quote itself. The price you hear on the call is the price on your invoice with no adjustments after the job is completed. For automotive work, providing the vehicle make, model, and year allows us to price the key cutting and programming accurately. For residential and commercial jobs, a brief description of the lock type and the work needed is usually enough for us to confirm a figure.
All residential and commercial locksmith work carries a 90-day warranty on parts and labour. Automotive key programming and car key services carry a 12-month warranty. If anything we installed, repaired, or programmed fails within the warranty period, we return and correct it at no additional charge. The warranty applies to the parts we supply and the labour we perform. Our technician walks you through what was done before leaving your location so you know exactly what is covered.
