When Should You Call a Locksmith?
A locksmith is not only for lockouts. For most people, the call they put off until a crisis is the one that would have cost the least — and solved the most — if they had placed it sooner. Knowing the right moments to pick up the phone helps you protect your home, your business, and your peace of mind before a problem becomes an emergency.
Here are the six situations where calling a professional locksmith is the smart move.
You Just Moved Into a New Home
The most overlooked security step after any move is rekeying the locks. The previous owners may have handed over every key at closing — but they almost certainly cannot account for every copy that was made over the years: contractors, housekeepers, family members, neighbours. You have no way to know who still has access.
Rekeying your locks after moving is fast, affordable, and the only way to guarantee a clean slate. A locksmith can rekey all of your exterior locks in a single visit, and at the same time assess whether the existing hardware is worth keeping or due for an upgrade. If you want to take the opportunity to go keyless, a visit is also the right time to discuss smart lock options.
Our residential locksmith services in Burlington cover rekeying, lock replacement, and security assessments — often completable the same day you call.
Your Keys Are Lost or Stolen
Lost keys are an inconvenience. Stolen keys are a security event.
If your keys were stolen — especially alongside a wallet with your ID or a phone with your home address in its contacts — the risk is real and immediate. A locksmith can rekey your locks the same day, cutting off access to whoever has the keys before they have the chance to use them.
Even if you believe the keys were simply lost, there is value in acting quickly. If your key ring had a fob, a loyalty card, or anything else that could identify your address, treat it as stolen and rekey accordingly.
Locks Are Sticking, Stiff, or Hard to Turn
A lock that is difficult to operate is not just an annoyance — it is a warning sign. Stiff locks typically indicate one of three things: the cylinder is worn and nearing failure, debris has accumulated inside the mechanism, or the door has shifted in its frame and the latch or deadbolt is binding against the strike plate.
In the Halton and Hamilton regions, seasonal temperature swings cause wood doors to expand and contract noticeably. A lock that worked smoothly in summer may become genuinely difficult to operate by February. Ignoring a stiff lock often ends with a snapped key in the cylinder — which is a more expensive fix than addressing the underlying problem early.
A locksmith can clean and lubricate the cylinder, diagnose any alignment issues, and recommend whether the lock needs service or replacement. For door alignment problems specifically, our post on why door alignment matters walks through what causes the issue and how it gets fixed.
You Want a Security Upgrade — Not Just New Keys
Upgrading your security does not require a break-in as a trigger. Common reasons homeowners contact us include wanting to switch from basic builder-grade hardware to higher-security cylinders, adding a deadbolt to a door that only has a knob lock, or keying all locks to a single key for convenience.
Keying your home locks alike is a simple upgrade that a locksmith can complete in one visit. If you are thinking about access control, high-security keys that cannot be duplicated at a hardware store, or multi-point locking systems for patio or entry doors, a professional assessment is the starting point.
Your Business Has Had a Staff Change
For commercial properties, a staff departure — particularly one that did not end well — is an immediate trigger to rekey or remaster any locks the former employee had access to. If the business uses a master key system, a locksmith can remaster only the affected level of the hierarchy rather than rekeying every door in the building.
Beyond staff changes, growing businesses often reach a point where loose key management becomes a real liability. That is typically the moment to evaluate access control systems — which log who enters and when, and allow you to revoke access instantly without rekeying physical locks.
Our commercial locksmith services are available across Burlington, Hamilton, Oakville, and the surrounding Halton region.
After a Break-In or Attempted Break-In
A break-in almost always damages the hardware — door frames get kicked in, cylinders get drilled or pried. Before you can feel secure again, the physical damage needs to be addressed properly, not just patched.
A locksmith can assess the door, the frame, and the locking hardware, and make recommendations that address the vulnerability rather than just replacing like-for-like. In many cases, the existing hardware was the reason the door failed — builder-grade deadbolts and weak strike plate screws are the most common culprits. An attempted break-in that did not succeed is equally important to follow up on: the attempt reveals exactly which door the would-be intruder thought was the weak point.
