Lock work in Newmarket
GTA Lockman Mobile Locksmith Services works on Newmarket homes, townhouse communities, Main Street businesses and vehicles. The technician comes to you with the parts and tools to rekey, repair, replace and install locks at the door, and to cut and program car keys at the vehicle.
Newmarket mixes a historic downtown with established neighbourhoods and newer subdivisions, and the lock work differs between them.

Call (647) 955-3277Request a free quoteThe heritage buildings along Main Street combine storefronts at street level with offices or apartments above, and many have rear entrances off laneways or parking areas. That layout creates a few recurring jobs:
- Shared entrances. A street door that serves both an upstairs tenant and a business needs keys that each party controls. A small keyed-alike or master-keyed arrangement often sorts it out. See master key systems for buildings and businesses.
- Rear doors. Laneway doors are the ones most often forced. A solid door, a latch guard and a deadbolt that throws fully every time make the biggest difference. See rear door security for shops and restaurants.
- Older storefront doors. Wooden and aluminium shop doors that have been repaired many times often need the closer, the strike and the lock adjusted together. See commercial door will not lock at closing.
Heritage storefronts sometimes carry original hardware worth keeping. Where an old lock cannot be repaired, a replacement can usually be chosen to fit the existing door preparation.
Established neighbourhoods near downtown
Older Newmarket homes often have original or early replacement doors, side entrances and detached garages. Typical requests are deadbolts added to doors that only have knob locks, repairs to doors that have sagged, and rekeying after a purchase. A lock that works with the door open but binds when it is shut is an alignment problem, covered on deadbolt repair.

Newer subdivisions
In the newer neighbourhoods, including those on the east and west edges of town, homes generally have builder hardware, attached garages and sometimes a keypad on the front door. New owners usually ask for:
- Rekeying after closing so builder, trade and previous-owner keys stop working. See lock changes after moving home.
- One key for the front, side, garage-entry and back doors.
- Keypad locks for children and regular visitors. See keypad lock installation.
- A stronger deadbolt and strike on the front door.
Townhouse and condo communities
In townhouse condominiums, the unit door is usually the owner's, while gates, mailboxes, common doors and garage entries belong to the corporation. Before changing a lock on a door you share with the community, check with the management office. For a suite or unit lockout, see apartment and condo lockouts.
Newmarket's winters bring the usual lock complaints: keys that will not turn in a frozen cylinder, deadbolts that stick as doors shrink and swell, and storm doors that stop latching. Do not pour hot water into a lock or use oil-based sprays; both make the problem worse later. See frozen or stiff door locks in winter.

Businesses beyond Main Street
Offices and retail units along Yonge Street, Davis Drive and the plazas near Upper Canada Mall, and industrial units elsewhere in town, use commercial hardware: narrow-stile storefront locks, steel doors, exit devices and master-keyed systems. Common work includes rekeying after staff turnover, key control for growing teams and access changes when a lease ends. See working with a commercial locksmith.
Vehicles
Car key replacement, fob programming and lockouts are done at the vehicle. Have the VIN, ownership documents and identification ready. See car key replacement and car lockout service.
Booking in Newmarket

Can original hardware on a heritage storefront be kept?
Often. Old locks can usually be repaired. Where one cannot be, a replacement is chosen to fit the existing door preparation.
Should I rekey a newer Newmarket home after buying it?
Yes. Rekeying makes builder, trade and previous-owner keys stop working and gives you a known number of keys.
Can all my exterior doors use one key?
Usually, if the cylinders share a keyway. Locks on a different keyway may need a new cylinder.
Who handles common doors in a Newmarket townhouse complex?
The condominium corporation. The unit door is usually the owner's, but gates, mailboxes and common doors belong to the corporation.
My lock is frozen. What should I avoid?
Avoid hot water and oil-based sprays. Warm the key, try gently, and use a lock de-icer. If it keeps happening, the lock needs servicing.
Do you work on businesses along Yonge Street and Davis Drive?
Yes, including storefront locks, steel doors, exit devices and master-keyed systems.
What do I need for a car key replacement?
The VIN, ownership documents and identification, plus any working key you still have.
