What's happening right now?

Locked out

Safely, right now

  1. Wait somewhere safe and warm: a neighbour's, your car, a coffee shop.
  2. Don't break a window or pry the door. It adds damage without getting you in sooner.
  3. Have a photo ID with your address ready if you can.

Key broke in the lock

Safely, right now

  1. Leave the lock alone: pushing the piece further in makes it harder to get out.
  2. Keep the piece you still have. It helps cut a new key.

Lock won't turn

Safely, right now

  1. Don't force the key. A bent or broken key makes it harder.
  2. Skip the oil, the glue and the hot water. They make it worse.

A door that latches on the first push, a deadbolt that throws fully, a key that slides in without a wiggle: these are small things that add up to a home that feels secure. We fuss over them so you do not have to.

The fix, explained · Mississauga

What is the door doing?

EmergencyHome Lockout ServiceYou reached the front step with the groceries, patted every pocket twice, and the house key is simply not there.

The fix

Different locks call for different openings, and a lockout visit starts by reading the hardware on your door. A spring latch in a knob or lever behaves differently from a deadbolt, a mortise lock in an older home has its own internals, and a high-security cylinder resists shortcuts that work on builder-grade hardware.

EmergencyBusiness Lockout ServiceThe heavy glass door has been scraping the threshold for weeks.

The fix

Authority for a business is a question about the company, not just the individual at the door. An owner shows identification and something connecting them to the premises, such as the lease or the business registration.

EmergencyBroken Key ExtractionThe key went in like any other morning, you turned it, and something gave with a small metallic click.

The fix

Freezing is one of the bigger seasonal causes of broken keys here. Meltwater runs into the keyway during a thaw and freezes overnight, so the plug is locked in ice, and most people respond by turning harder.

EmergencyBreak-In Damage Lock RepairSomeone smashed the little window beside the door, reached in and turned the thumb-turn.

The fix

Break-in damage lock repair is the visit that turns a forced door back into a locked one. The locksmith first confirms you own, rent or manage the property, then looks at everything the attack touched: the lock, the bolt, the strike plate and wood behind it, the door edge, the hinges and any glass beside the door.

EmergencySeized & Jammed Lock OpeningThe shop's lever handle goes down as usual, but the latch inside the mortise case never pulls back.

The fix

Most seized locks can be saved, and keeping your existing hardware is the aim. A cylinder that has stopped turning is usually recoverable with cleaning and fresh internal parts.

EmergencyLost Keys — Same-Visit RekeyYou were shovelling the driveway after dark and the ring must have slid out of your coat pocket somewhere under a metre of snow.

The fix

A missing key is also the moment a household can stop carrying four. Because a rekey sets a fresh combination in every cylinder anyway, the locksmith can set the same combination in all of them, provided they share a keyway family, so the front door, back door, garage entry and side gate open with one key.

A locksmith you can talk to

We keep a proper stock on the van, and that shapes how a visit goes. Cylinders in the common finishes, strikes, pins, blanks for the keys most houses around here use, closer parts and padlocks all ride with us, so most repairs are done with what is already on the shelf rather than something ordered in.

  • Time to understand first. We do not start work until you understand what we found. That might take two sentences or a longer chat; either is fine.

  • A quiet, careful approach. Locks are opened and fitted with patience rather than force wherever the design allows. Your door and frame matter as much as the lock.

  • Everything tested, everything explained. Before leaving we run through each lock and key with you, show you anything new and leave a note of what was done.

Ordinary locks keep out the curious. High security locks keep out someone who has decided to get in and has tools. The difference lives in four places: cylinder, bolt, strike and key, and each is explained here in plain terms.

Your roommate moved out last weekend. Rent is settled, the room is empty, and the key is still on their ring. You trust them, but the lock on your front door should answer to the people who actually live here.

What the census means at the door

38%

Homes of every age. About 38% of homes in Mississauga were built in 1980 or earlier, according to the 2021 Census.

In an area of varied housing ages, rekeying is the one job that fits every door. Old cylinders and new ones both take fresh pins, so a household moving into either kind of home can start with keys that nobody else holds.

37%

Single-detached houses make up about 37% of homes in Mississauga (2021 Census).

Attached housing turns over more often than detached, so rekeying between tenants or owners is a constant. Because suite doors tend to be standard, the job is usually a straightforward pin change and a fresh set of keys cut on site.

Good questions about locks

Advice · (289) 805-7422

Can we put a keyed deadbolt on both sides of the back door for extra security?

On a door people leave through while the building is occupied, the door needs to open from inside with one motion and no key, so a key-both-sides bolt is not the right tool there. Security is added instead with a heavy-duty exit device and a reinforced strike, a keyed trim outside, an alarm contact, or a door position sensor on the access system, all of which keep the way out clear.

How long does a business lockout take?

It depends on the hardware and what else is wired to it. A standard storefront cylinder or office lever on a well-hung door is often a short job once authority is confirmed. A high-security cylinder, a frozen lock, a dropped door or a dead access controller adds time, and so does rekeying several doors afterwards. The locksmith gives you a realistic idea on the phone once you describe the door and the situation.

Do you work with our alarm company and access-control provider?

Yes, and it makes the visit smoother. The alarm station is told an entry is expected and the authorised person handles the disarm and password. For access control, the provider can often confirm the controller's status, unlock a magnetic lock remotely, or re-enrol fobs once you are inside, while the locksmith handles the mechanical side and the override cylinder. Nobody's wiring is cut; each party does the part it is set up to do.

Are high security locks only for businesses?

Not at all. Homes are the most common place they are fitted, especially after a move, a break-in nearby, or the realisation that too many keys have been handed out over the years. A graded deadbolt with a patented cylinder and a reinforced strike is a modest, quiet upgrade for a front or side door. Businesses tend to go further, with laboratory-rated cylinders, heavy lock bodies and a documented key system across many doors.
