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.
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.

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

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.
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.
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.
