Half the lock trouble we see is really a door problem: hinges that have sagged, a frame that moved with the seasons, a strike a few millimetres off. We fix the alignment along with the lock, so the repair holds through next winter too.

Practical locksmithing for real doors.

Condo and apartment work has its own etiquette. We coordinate with the property manager, respect the building's existing key system rather than cutting across it, and match finishes so a new suite lock does not stand out in a hallway of identical doors. Common areas, bike rooms and parcel lockers each have hardware chosen for heavy shared use, and we service those too.

The key you reach for. The door you come home to. Good locksmith work begins with understanding how you use them.

  • Explained before any tool comes out. You will hear what we found, what we suggest and why, before anything is changed. If you want a minute to think, take it.
  • Choices, not a single answer. Most problems have more than one fix. We lay out the practical options and the trade-offs, then let you choose the one that fits your home and budget.
  • A tidy doorstep. Shavings swept, packaging taken away, the old hardware offered to you or disposed of. The only sign we were there is a lock that works.

Small things.
Big difference.

Choosing a service is easier when you know what each one actually changes. Rekeying changes the key, replacement changes the hardware, repair keeps what you have working, and installation adds something new. The sections below sort our work along those lines.

1/3Deadbolt Installation

Someone tried the door last winter. The frame took it, but the strike plate is bent, one screw hole is stripped, and the bolt sits in the pocket at a slight angle. It still locks, and it still bothers you every night.

The restricted keys you bought years ago are no longer restricted; the locksmith mentioned the patent has run out and blanks are sold openly. Your key control quietly stopped being control.

3/3Commercial Rekeying

The manager's key ring went missing somewhere between the bank and the car, and the master on it opened every door in the building. Until the cylinders are changed, whoever finds it is holding the run of the place.

High Security Locks

For homes, high security usually means a graded deadbolt, a patented cylinder and long screws into the frame. For businesses it adds laboratory-rated cylinders, heavy lock bodies and a key register. Both start with a conversation about what the door protects.

Safes

Safe Opening & Combination Change

Pry marks circle the dial after an overnight break-in attempt, and the safe now refuses every number that used to open it, as if something inside has locked itself down.

Safe Installation & Servicing

A homeowner inherited a heavy old dial safe from a parent's house, moved it into the new place, and has no idea whether the bolt-work still works, whether the lock is sound, or how it should be anchored.

Which fix fits?

Your front door has only the lock in the knob, nothing else.

Sensible optionAdd a proper deadbolt above it.

WhyA bolt into a reinforced strike is what actually holds a door; the knob just keeps it closed.

The deadbolt wobbles and the screws spin in the door.

Sensible optionRe-fit the hardware and repair the bore.

WhyStripped holes can be plugged and redrilled, so the same lock sits tight again.

You are tired of carrying keys and want a code instead.

Sensible optionA keypad deadbolt with a key override.

WhyEach family member gets a code, guests get a temporary one, and a mechanical key remains for the day the batteries die.

Overnight someone forced the back door, and the cylinder face is scarred, the metal around the strike has pulled loose from the frame, and the latch no longer sits flush.

Sensible optionCommercial-Grade Lock Replacement

WhyCommercial-grade lock replacement swaps hardware that is worn, damaged, mismatched or simply not rated for a business door with hardware built for that duty: a mortise lock body, a heavy cylindrical lockset, or a narrow-stile lock or hookbolt for an aluminum storefront door.

After a week of humid weather the back door has swollen in its frame.

Sensible optionHome Lockout Service

WhyIf you rent, a lockout visit works much the same way, with a little extra care around who holds which keys.

Minus eighteen with a wind, and the exterior cylinder on the shop door has frozen solid overnight after yesterday's slush.

Sensible optionBusiness Lockout Service

WhyThe end of a business lockout is a paper trail as well as an open door.

How a visit goes

Describe the property, the hardware and what has changed, and the visit starts from what you have seen.

    A look inside the keyway

    We check how deep the fragment sits and whether the cylinder was already worn or dry. That tells us how to draw the piece out without pushing it further.

    Drawing the piece out

    With extraction tools and patience the broken blade comes out whole. We clean and lubricate the cylinder so the next key goes in smoothly.

    Cutting a fresh key

    A key that snapped was usually tired. We cut a new one from the two halves or from the lock itself, test it and suggest retiring any other worn copies.

2021 Census

What it means at the door

About 19% of homes in Markham were built in 1980 or earlier, according to the 2021 Census.

Newer homes

During construction many people hold a key: framers, finishers, painters, the sales office. Where homes are new, rekeying the exterior doors to a fresh key is the tidy way to close that chapter, and it takes a single visit.

Single-detached houses make up about 56% of homes in Markham (2021 Census).

In an area with both houses and attached homes, the work varies by the door. A detached house wants all its exterior doors on one key; a suite door wants a cylinder that suits a metal frame and respects building rules. A locksmith carries parts for both.

Short answers to common questions

Questions · (289) 306-0671

How do I order extra keys later?

An authorised person contacts the locksmith who holds your system, quotes the system reference, and the key is cut from code and numbered into the register. Some systems use a physical authorisation card, others an online validation, and business systems often require a signature that matches one on file. The key is collected or delivered, and the record shows the new total. It is deliberately not something a stranger with your key can do.

Will the new cylinder fit my existing locks?

Usually. High security cylinders are made in the common formats: key-in-knob and lever, rim, mortise and interchangeable core, and many are designed to drop into popular residential and commercial locks. The locksmith identifies your format and confirms fit before ordering. Where a lock is an odd size or in poor shape, a matching lock body is fitted instead, and the door preparation is reused wherever it is standard.

What does key control mean in practice?

It means your key can only be copied through the locksmith who manages your system, after checking that the person asking is on your list of authorised names. Blanks for the keyway are not sold to hardware stores or kiosks while the patent lasts. Each key is numbered and recorded, so you know how many exist. For a home that ends the worry about old copies; for a business it turns a lost staff key into a known, manageable event.

Request a visit

For a condo or apartment in Markham we work within the building's rules. The suite door is yours and gets whatever cylinder, strike or closer suits the way you live. Common doors belong to the building, and we coordinate with management before touching them. You get a secure unit without a letter from the board.
