Lock work in Oshawa

GTA Lockman Mobile Locksmith Services works on Oshawa homes, rental properties, businesses and vehicles. The technician works from a fitted van at your address, so rekeying, lock changes, repairs, keypad installations and car key programming are usually done in one visit.

Oshawa's housing ranges from older brick homes in the central and southern neighbourhoods to newer subdivisions in the north, and it has a large rental market around the post-secondary campus. Each brings a different set of lock questions.

Rentals near the north campus

Request a visit →

Ontario Tech University and Durham College share a campus in north Oshawa, and the streets around it have many shared houses, rooms for rent and basement apartments. Rentals turn over every year, often in late spring and late summer, and keys go with them.

Lock work that comes up around student and shared rentals:

  • Rekeying between tenancies. Old tenants' copies, friends' copies and keys cut at a hardware counter all stop working at once. See lock rekeying.
  • Bedroom door locks. Shared houses often want keyed locks on individual rooms. The rules and the practical choices are on student rentals and shared houses.
  • Basement suite entrances. A separate entrance needs a lock suited to an exterior door, and sometimes a connecting door between units that locks from both sides. See basement apartment entrance locks.
  • Keys that come back at move-out. A record of how many keys were issued makes it clear whether everything was returned. See returning keys at the end of a tenancy.

Landlords should check Ontario's rules before changing locks on an occupied unit. A summary is on tenants and lock changes in Ontario.

Older homes in central and south Oshawa

01

Many of the older houses around the downtown and towards the lake have doors that have been repainted, rehung and refitted several times. Typical findings:

02
  • A deadbolt that binds because the door has dropped on its hinges.
  • A strike plate held by short screws into a soft or split frame.
  • Several sets of old holes from previous hardware.
  • Side and back doors with knob locks only, and no deadbolt.
03

The usual fix is to make the door close and latch properly, reinforce the frame at the strike, and then fit or rekey the locks. See side and back door lock repair and door hinge security.

Newer homes in north Oshawa

The newer subdivisions in north Oshawa generally have builder hardware and often an attached garage. New owners commonly ask for rekeying after closing, an upgraded front deadbolt, a keypad for the front or garage entry door, and one key across all the exterior doors. See one key for every door and keypad lock installation.

05

Oshawa businesses

Downtown storefronts, plazas, offices and industrial units each have different needs. Storefront aluminium doors use narrow-stile locks; industrial units use steel doors, latch guards and padlocks; offices often need a small master key system. Common calls are rekeying after staff leave, doors that will not lock at the end of the day, and rear doors that have been forced. See working with a commercial locksmith and commercial storefront door locks.

Lockouts and lost keys

Call (647) 955-3277 →

For a house lockout, the technician first confirms that you live at the address or are responsible for it, then opens the door with a non-destructive method wherever the lock allows. If the keys are lost rather than locked inside, rekeying afterwards is usually sensible. See house lockout service and lock changes after lost keys.

Car key replacement, fob programming and car lockouts are handled at the vehicle, in a driveway, a lot or a workplace. Bring the VIN, the ownership documents and identification. See car key replacement.

Questions about locksmith services in oshawa

Yes. Rekeying makes every old tenant's copy stop working, and you get a known number of new keys to issue.

Can you rekey a student rental between tenants?

Yes. Rekeying makes every old tenant's copy stop working, and you get a known number of new keys to issue.

Can bedrooms in a shared house have their own locks?

Usually. Keyed bedroom locks are common in shared houses, and they can be set up so the landlord holds a key that opens each room.

My older Oshawa home's deadbolt sticks. Does it need a new lock?

Often not. On older doors the cause is usually a dropped door or a moved strike. Adjusting the door and strike often fixes it.

Do you work in north Oshawa subdivisions?

Yes. Common jobs there are rekeying after closing, upgraded deadbolts, keypads and one key for all exterior doors.

Can a landlord change the locks on an occupied Oshawa rental?

Not without following Ontario's tenancy rules. Check the Residential Tenancies Act requirements before changing locks on an occupied unit.

Do you work on Oshawa storefronts and industrial units?

Yes, including narrow-stile storefront locks, steel doors, latch guards and master-keyed systems.

Can you replace a car key at my workplace?

Yes, if the technician can work safely beside the vehicle. Bring the VIN, ownership documents and identification.

What do you need from me to book?

The address, the type of property, what needs doing and whether you have a working key.
