Who answers when you call

Every home has a door everyone actually uses and a door nobody thinks about. The side entrance by the driveway, the door from the garage, the basement walkout: these are the ones that tend to carry the flimsiest hardware and get the least attention. Part of our first visit is walking the whole perimeter with you, so the effort goes where the traffic and the risk really are.

Shop rules

Sound hardware, straight answers.

  1. A look before a verdict. We inspect the door, frame and lock before suggesting anything. Diagnosing from the driveway is how people end up with parts they did not need.
  2. Two or three real choices. Where there are sensible alternatives we explain them side by side, including the option of doing less than you expected.
  3. The job finished properly. Tested, aligned, cleaned up and demonstrated. We do not consider a lock done until you have turned the key yourself.
  4. Open 24/7, same fees any hour. Reach out and we'll explain the options.

High Security Locks

Drawn forMarkham
ScaleNot to scale

A lock's rating comes down to how long it holds against a skilled attacker with tools. Doors are only as good as their frames. High security work respects both facts, hardening the cylinder and the assembly around it at the same time.

    You have lost count of how many people have had a key to your house over the years: cleaners, a contractor, a former partner, the previous owner's family. The lock still works, but you no longer know who else it works for.

If You are renting, and the landlord says the locks were never changed.

2021 census: what it means at the door

Every square is one home in a hundred.

  • 19 in 100 homes · newer homes
  • About 19% of homes in Markham were built in 1980 or earlier, according to the 2021 Census.In newer developments the hardware is often the same finish and style from house to house. A locksmith can offer upgrades that match what is already there, so a stronger cylinder or a new lever set fits in without looking like an afterthought.
  • Single-detached houses make up about 56% of homes in Markham (2021 Census).Mixed housing brings mixed hardware ages as well as types. A locksmith may rebuild a mortise lock on a semi-detached house and then set up a keypad on a townhouse door across the road, and treats each with the care its owner expects.

Frequently asked questions

What is a keying chart and why does it matter afterwards?

A keying chart is a plain list of every opening, the key group that operates it, the code stamped on those keys and the number issued. Months later it lets you answer exactly which doors a missing key opened, and it lets a locksmith add a new door to the system without changing anything else. Keep it with the key register, somewhere locked, with a copy off site.

Can all our doors be put on a single key?

Yes, if the cylinders share a keyway or can be fitted with ones that do. Keying everything alike is popular with small shops because staff carry one key and spares are simple. The trade-off is that one key then opens the cash room as readily as the front door. Many businesses choose a middle path: the doors everyone uses on one key, the sensitive rooms on another, and an owner's master that opens both.

Do I need my landlord's consent before rekeying my unit?

Read the lease, because that is where the answer lives. Commercial tenancies are governed mostly by the lease itself, and many leases require the tenant to tell the landlord when locks change, to provide a key for emergencies, or to use the landlord's approved locksmith. Doors on the building's master system, such as corridor or service doors, are normally the landlord's to change. Bring the lease to the assessment and the locksmith will sort the doors accordingly.

What happens when the patent on my keys runs out?

The mechanical resistance of the cylinder does not change, but blanks may become openly available, so copy control weakens. Manufacturers issue new patented keyways as older ones expire, and the usual answer is to move to the next generation by changing cylinders and keys while keeping the lock bodies. Your locksmith notes the patent term at handover so the date is on the calendar rather than a surprise years later.
