Lock Rekeying Ottawa: The Fast, Affordable Way to Control Who Holds a Key

What Lock Rekeying Involves

Every pin-and-tumbler lock works off a set of small spring-loaded pins cut to match one specific key. Rekeying means removing the cylinder, swapping those pins for a new combination, and cutting fresh keys to match. The lock body, faceplate, and bolt mechanism all stay exactly as they were. Nothing about the outside of your door changes, only the code the mechanism responds to.

Because the hardware itself isn't being replaced, rekeying is quicker and cheaper than a new lock, and it's the standard first move whenever the concern is who holds a key rather than how the lock itself is performing.

Signs You Should Rekey Now

• You just closed on a home and have no idea how many keys are floating around
• A tenant moved out and didn't return every key they were issued
• A roommate, ex-partner, or former employee had access you want to remove
• You lost a keyring and can't account for where the keys ended up
• A contractor, dog walker, or cleaner was given a key temporarily and the arrangement has ended
• You want every exterior lock keyed the same after replacing just one

Why Homes and Businesses Need Rekeying

Most rekeying calls come down to a change in who should reasonably have access, not a mechanical problem with the lock. New homeowners are the largest group we see, closely followed by landlords managing tenant turnover, since Ontario's rental market moves quickly and few outgoing tenants hand back every copy they made. Small business owners call us after staff changes, particularly when an employee with a storefront key leaves on short notice.

Rekeying vs. Full Lock Replacement

We rekey when the existing lock is a reasonable grade, operates smoothly, and shows no signs of drilling, picking, or physical damage. This covers the overwhelming majority of calls, especially for homeowners who just want confidence after a move.

We recommend replacement instead when the lock is a low-grade builder's model nobody would choose on their own, the cylinder or bolt shows wear that rekeying can't fix, or a customer wants to move up to a higher security grade or a smart lock. We'll always look at the hardware in person before recommending one over the other, rather than assuming replacement is needed by default.

Residential Rekeying

For homes, we typically rekey every exterior door to a single key in one visit, front door, back door, and any side or garage entry included. This is especially common right after closing on a house in areas like Nepean or Stittsville, where new owners understandably don't want to spend their first weeks wondering who else might have a copy from before.

Commercial Rekeying

Commercial rekeying often needs to account for staff hierarchy, not just a single new key. We regularly set up master key systems for small offices and storefronts around Ottawa and Kanata, where an owner or manager needs a key that opens everything while individual staff get access limited to their own area.

Lock Types We Rekey

• Standard pin-and-tumbler deadbolts and knob locks
• Mortise locks found in older homes and commercial storefronts
• Lever handle locks common in offices and multi-unit buildings
• High-security cylinders, where permitted by the manufacturer's key control policy
• Padlocks and secondary locks, such as those on sheds or gates

Security Considerations

Rekeying only changes who can use the existing lock, it doesn't upgrade the lock's resistance to picking, drilling, or force. If your current hardware is a basic builder's-grade cylinder, that's worth discussing at the same visit. Many customers choose to rekey now and revisit a security upgrade later, which is a reasonable approach as long as it's a deliberate decision rather than an oversight.

Preventative Habits

• Rekey immediately after any move, whether you're the buyer or the landlord between tenants
• Keep a written log of who has been issued a key and when it was returned
• Avoid duplicating keys at unstaffed kiosks that don't verify authorization
• Rekey rather than assume a returned key means every copy came back with it

What Happens During a Service Call

We inspect each lock to confirm it's in good working condition and compatible with rekeying, then remove the cylinder, replace the pins, and cut new keys on-site. If you want every door keyed alike, we handle that as part of the same visit so you leave with one key that works everywhere it should. Before we leave, we test every lock with the new keys in hand.

Safety Tips

• Don't wait to rekey after a breakup, roommate departure, or tenant move-out; do it the same week
• Never assume a returned key means all copies were returned
• Keep spare keys with a trusted neighbour rather than hidden outside the home
• If you suspect a lock was tampered with, have it inspected before rekeying rather than after

Why Professional Rekeying Matters

Rekeying looks simple from the outside, but pin selection matters more than most homeowners expect. Using the wrong pin combination can leave a lock easier to pick than before, or create a key that works but binds slightly every time it's turned. We test every rekeyed lock under real use before considering the job finished, not just a quick turn with the door open.

Why Local Service Matters

We're based in Ottawa and serve the surrounding Valley, including Kanata, Orleans, Barrhaven, Rockland, Arnprior, and Carleton Place. That local footprint means we can usually get to a new homeowner or a landlord between tenants the same day, which matters most in exactly the situations where rekeying is needed urgently.
