How Barrhaven grew
Barrhaven's first subdivision houses went up along Larkin Drive in the late 1960s. Minto built the original Barrhaven development and Cedargrove through the 1970s and 1980s, and for a time it looked as if growth would stop there: in 1978 the Ontario Municipal Board limited the planned expansion, until the provincial cabinet overruled it in 1979.
Growth has barely paused since. Half Moon Bay went from a few dozen residents in 2006 to more than 15,000 in 2021, and Barrhaven as a whole counted more than 103,000 people at the 2021 census, which makes it larger than many Ontario cities.
Until 2001, Barrhaven was part of the City of Nepean. Today it has its own character, and its own pattern of locksmith work: a small core of houses about fifty years old, surrounded by streets so new that many owners are still on the keys the builder handed them.

Builder keys and why new homes get rekeyed
A new house collects keys long before its owner gets one. During construction, trades, site supervisors and inspectors need to get in, and many builders use construction keys and master systems to manage that. Sales offices hold keys for showings, and the keys you are handed at closing may not be the only ones that were cut.
Some builder locks are designed so that the first use of the owner's key cancels the construction key. That only works if it is done correctly, and many owners never learn whether theirs was. Rekeying when you take possession takes the question away: new pins, new keys and a number of copies that you decide.
The same applies to resale homes in Barrhaven's older streets, where the previous owners, their family and their contractors may all still have a key. The residential locksmith page explains what rekeying involves.

Patterns rather than rules, but they hold for most streets.
The mailbox at the end of the street
Much of Barrhaven gets its mail from Canada Post community mailboxes, and their keys are among the most often lost.
What Barrhaven residents call a locksmith about
The most common calls, with links to the pages that cover each one.
Getting the most from a smart lock
Keypad and smart deadbolts suit busy family homes, as long as they are set up properly.
Choose one with a keyed backup
When the battery or the electronics fail, a key still gets you in.
Key the backup to your other locks
So the same key opens the front, back and garage doors.
Give each person their own code
Then you can remove one person's access without changing everyone's.
Change the batteries every fall
Cold drains them fast. Most locks warn you, but only if someone is listening.
Check the strike
A smart lock is only as strong as the frame it locks into. Long screws in the strike plate still matter.
Car keys in a commuter suburb
Most Barrhaven households depend on two cars, and car keys are a large part of what a Barrhaven locksmith does.
Townhouse rows and shared walls
Barrhaven has a great many townhouses, including back-to-back and stacked units where several homes share a building and sometimes an entrance. Each unit usually has more doors than people expect: the front door, the door from the garage, a back or balcony door, and sometimes a separate entry to the lower level.
Keying all of them to one key is usually straightforward in a newer townhouse, because the builder used the same hardware throughout. Where an owner has replaced a lock with a different brand, one cylinder may need to be swapped to match.
If the townhouse is part of a condominium, anything shared, such as a common entrance, parking or mailroom, belongs to the condominium corporation, and only your own unit doors are yours to change. A locksmith in Barrhaven will check before touching anything shared.
Old Barrhaven, fifty years on
The houses along Larkin Drive and in the first Minto streets are now around fifty years old, and they are a different job from the new builds a few kilometres south. Their doors have been replaced, rehung and repainted, and their locks have been changed one at a time by successive owners.
A Barrhaven locksmith working in the older streets usually finds a mix: a newer deadbolt on the front door, an original handle on the side door, a patio door with its factory latch, and a garage entry door with no deadbolt at all. Bringing it all onto one key, and adding a deadbolt where one is missing, is a common one-visit job.
These houses also have older wood frames, which can split around the strike after decades of use. A reinforcement plate and long screws into the stud restore the frame so the deadbolt holds as it should.
What locksmith work costs in Barrhaven
You get a price on the phone once the job is described, and it is confirmed before work starts. For rekeying, it helps to count the exterior locks before you call, including garage entry and patio doors.
Newer homes are often quicker to work on, because the hardware usually comes from one maker and shares a keyway. Older houses with mixed brands, keypad locks that need resetting and extra doors add time. Business premises are quoted after a look at the doors.
Urgent calls at night or on weekends cost more than booked visits. If a problem can safely wait until morning, you will be told.
Questions people ask
Do I need to rekey a brand-new house?
It is a good idea. Construction, inspection and sales keys pass through many hands before closing. Rekeying on possession day is inexpensive and means you know exactly who can get in.
Do you cover all of Barrhaven?
Yes, from old Barrhaven and Cedargrove to Longfields, Davidson Heights, Half Moon Bay, Stonebridge and the newest streets to the south.
Can you fix a keypad lock that will not accept the code?
Usually. It is often a low battery or a lock that has lost its programming. The lock can be reset and the codes set again, and the keyed backup rekeyed if needed.
I lost both keys to my community mailbox. Can you help?
Canada Post owns those locks, so new keys come from Canada Post, for a fee of $29 plus tax. If you still have one key, a copy can be cut.
Can you make a spare car key for my teenager?
Yes. A spare made from a working key is quick, and it can be cut and programmed in your driveway. It is much cheaper than replacing a key after the only one is lost.
Can all the doors on my townhouse use one key?
Usually. Newer townhouses tend to have hardware from one maker, so every exterior lock can be rekeyed to one key. A replaced lock from a different brand may need a matching cylinder first.
My new Barrhaven home came with a keypad lock. Should I change the code?
Yes. Builder and previous-owner codes should be changed the day you move in, and old users deleted from any app. If the lock has a key cylinder, rekey it to match your other doors at the same time.
