Alliston is the largest community in the Town of New Tecumseth, in southern Simcoe County, alongside Beeton and Tottenham. GTA Lockman Mobile Locksmith Services works on homes, rental units, businesses and vehicles in Alliston and the surrounding area, with the parts and tools to finish most jobs in one visit.
Alliston is outside the core GTA, so when you call, give us the address and the job and we will confirm when a technician can attend.
Alliston has an older town centre with houses from many decades, and newer subdivisions that have grown around it. The lock work tends to split the same way.

In households where people work shifts, as many do at the large manufacturing plants in and around town, family members come and go at different hours. When that happens, keys get passed around, left under mats or copied for relatives. A keypad lock on the most-used door, with separate codes for each person, means a code can be changed when circumstances change, and nobody needs a hidden key. See spare keys: how many and where to keep them.

Alliston has houses converted into rentals, basement apartments and small multi-unit buildings. Landlords commonly need rekeying between tenancies, separate keying for each unit and a key for the common entrance, and repairs after move-out. See lock repair after tenant move-out and basement apartment entrance locks. Before changing locks on an occupied unit, check Ontario's tenancy rules on tenants and lock changes in Ontario.
Farms and rural homes around Alliston, Beeton and Tottenham usually have outbuildings and equipment storage with their own padlocks. Keying them alike makes them easier to manage. See shed, garage and outbuilding padlocks. For properties left empty for stretches, see cottage and rural property locks.
Shops, offices and industrial units in New Tecumseth need commercial hardware: storefront locks, steel doors, latch guards, exit devices and, for larger buildings, master-keyed systems. Rekeying after staff changes is the most common request. See working with a commercial locksmith.
For a house lockout, the technician confirms your right to enter before opening the door, using a non-destructive method wherever the lock allows. See house lockout service.
Car key replacement, fob programming and car lockouts are handled at the vehicle. Have the VIN, ownership documents and identification ready. See car key replacement and car lockout service.
We also work in Caledon and Orangeville. A full list is on our service locations.
