Ottawa, ON is a city of century homes in neighbourhoods like the Glebe and Westboro, sprawling suburban builds further out, and everything in between — condos, semis, bungalows, and new-construction two-storeys. Whatever kind of home you own, one thing stays true: if you don't know exactly who holds a key to your front door, you don't really have control over who can walk through it. That's where residential lock rekeying comes in, and it's one of the most requested services our team handles across Ottawa.
Rekeying means changing the internal pins of your existing lock so that old keys stop working, while a fresh set of keys is cut for the new configuration. The hardware on your door stays the same — the lock body, the finish, the deadbolt you already picked out — but the mechanism inside is reset. It's quicker and less expensive than full lock replacement, and in the vast majority of cases, it accomplishes exactly what a homeowner needs.
Why Ottawa Homeowners Choose Rekeying
Ottawa's housing stock is genuinely mixed. Older homes in the core often still have their original hardware, sometimes decades old, with keys that have been copied and handed out more times than anyone can track. Newer subdivisions on the city's edges tend to have builder-grade locks installed by the developer, and builders rarely limit how many key blanks were cut during construction — contractors, inspectors, and real estate agents may have all had access at some point.
In both cases, rekeying gives homeowners a clean slate without the cost of tearing out hardware that's otherwise in good shape. It's a practical, affordable way to reclaim control over a property.
Common Situations Where Rekeying Makes Sense
- You just closed on a home and have no idea how many keys are floating around from the previous owner
- You're renting out a property and a tenant has moved out
- You've lost a key, or one was stolen along with a bag or wallet
- A contractor or renovation crew had a key during a home project and the work is now finished
- You're going through a separation and need to remove a former partner's access
- A family member — an adult child, a former roommate, an ex-caregiver — no longer needs a key
- You inherited a property and have no idea who might still hold a copy of the key
Locks We Rekey in Ottawa Homes
Most standard residential hardware can be rekeyed, including:
- Deadbolts (single and double cylinder)
- Entry door knob locks
- Lever handle locksets
- Patio and garage entry door locks
- Mailbox and secondary storage locks, where compatible
If your locks are mismatched — a common situation in older Ottawa homes that have had doors replaced over the years — we can often rekey everything to a single key, so you're not juggling a ring full of similar-looking keys.
How the Rekeying Process Works
- Assessment — We look at your existing hardware, brand, and condition to confirm it's a good candidate for rekeying rather than replacement.
- Pin removal — The lock cylinder is opened and the existing pin set is removed.
- New pin installation — A new pin combination is installed that matches a freshly cut key.
- Testing — Every lock is tested multiple times to make sure it turns smoothly and locks securely.
- Key handoff — You receive your new keys on the spot, and old keys are confirmed non-functional.
Most residential rekeying jobs are completed in under an hour, depending on how many doors are involved.
Rekeying vs. Replacing Locks
| Rekeying | Full Replacement | |
|---|---|---|
| Cost | Lower | Higher |
| Time | Usually faster | Longer, especially with multiple doors |
| Keeps existing hardware/finish | Yes | No |
| Best for | Hardware in good condition | Damaged, outdated, or mismatched hardware |
| Upgrades security grade | No | Yes, if you choose higher-grade hardware |
If your current locks are in solid shape and you simply need to control who has access, rekeying is almost always the smarter first step. If your hardware is old, worn, or you want to upgrade to smart locks or higher security-grade deadbolts, replacement may make more sense — and we're happy to walk you through that decision honestly rather than upselling you on hardware you don't need.
Benefits of Hiring a Professional
DIY rekeying kits exist, but there's a real difference between a kit from a hardware store and a technician who does this daily. A professional locksmith can:
- Confirm all your locks are actually rekeyable before you spend money
- Rekey mismatched hardware to a single key
- Spot signs of a lock that's worn out and likely to fail soon
- Complete the job correctly the first time, without stripped pins or a lock that sticks afterward
- Advise honestly on whether rekeying or replacement is the better long-term choice for your specific doors

A Few Ottawa-Specific Considerations
Because Ottawa has such a wide range of housing ages, it's worth having your locks looked at even if nothing seems obviously wrong. A lock that's technically functional can still be years past due for a rekey, especially if you've never had it done since moving in. If you own a home in one of Ottawa's older neighbourhoods, don't be surprised if your hardware is a brand that's no longer common — we carry a wide range of pins and can usually work with what you already have.
