When to Call a Residential Locksmith

Most homeowners only think about their locks when something goes wrong. But a residential locksmith handles a much wider range of situations than just lockouts. Here’s what typically brings people to call:

Understanding Lock Grades (Grade 1, 2 & 3)

In Canada, residential locks are rated by ANSI/BHMA (American National Standards Institute / Builders Hardware Manufacturers Association). The grade system reflects how well a lock withstands attacks, wear, and failure:

Most detached homes in the Toronto area should have Grade 1 deadbolts on all exterior doors. Condos and apartments should verify with their building management what locks are permitted, as some buildings require specific hardware or master-key-compatible cylinders.

Deadbolts vs. Knob Locks: What Actually Secures Your Home

A common misconception is that a door knob lock provides meaningful security. It doesn’t. Here’s the honest breakdown:

Deadbolts

A properly installed Grade 1 deadbolt with a 1-inch throw bolt is the foundation of residential door security. When the bolt is extended, it’s embedded in the door frame, making the door extremely resistant to kick-in attacks. Key characteristics of a secure deadbolt installation:

• Strike plate secured with 3-inch screws that reach the door’s studs — not just the thin door frame
• At least a 1-inch throw (the bolt extends 1 inch into the frame)
• Hardened steel bolt that resists sawing
• Anti-pick and anti-drill pin tumbler or disc detainer cylinder

Knob locks

A standard knob or lever lock can be defeated with a sharp kick, a pair of pliers twisting the knob, or a credit card shimming the latch. These locks are appropriate for interior doors only. Using a knob lock as your only exterior security leaves your home vulnerable.

The most common residential break-in method in the Greater Toronto Area is a front or back door kick-in. A reinforced strike plate and Grade 1 deadbolt reduces the force needed to kick a door in by more than 10 times.

Rekeying vs. Lock Replacement: Which One Do You Need?

These two services are frequently confused. Here’s the clear distinction:

Rekeying

The locksmith opens the lock cylinder and replaces the internal pin tumblers with new ones cut to match a new key. The external hardware stays exactly the same. Your existing keys will no longer work, and a new set of keys is provided. This is the right choice when:

• You’ve moved into a new home and want to invalidate previous keys
• You’ve lost track of who has copies of your key
• A tenant is leaving and you need to revoke their access
• The lock hardware is in good physical condition
• You want to save money — rekeying is typically 60–70% cheaper than replacement

Lock replacement

The entire lock hardware is removed and replaced with new hardware. This is the right choice when:

• The existing lock is damaged, worn, or a low-grade model you want to upgrade
• The lock has been forcibly compromised in a break-in attempt
• You want to upgrade to a smart lock or a different style
• The cylinder type is not compatible with your door thickness or existing hardware

Moving Into a New Home? Do This First.

Whether you’re buying your first home or moving into a new rental in Toronto, rekeying or replacing the locks is the single most important first step. Here’s why it matters more than most people realize:

• Previous owners: Sellers rarely recover every key copy. Family members, dog walkers, house cleaners, and neighbours may have had keys for years.
• Real estate ecosystem: Listing agents, showing agents, home inspectors, stagers, and other professionals may have had access during the sale process.
• Contractors and tradespeople: Any renovation work done by the previous owner may have left contractors with key copies.
• Rental properties: Former tenants in buildings with no master key management system may have copies of keys they never returned.

The cost of rekeying all exterior locks on a typical Toronto home is a fraction of the cost of a break-in, a theft, or even the peace of mind it provides. We recommend doing it within the first 48 hours of occupancy.

What “all exterior locks” means for a typical Toronto home

• Front door deadbolt
• Front door knob/lever lock (if separate cylinder)
• Back door deadbolt and/or handle set
• Side door or garage entry door
• Any gate or outbuilding with a keyed lock
• Mailbox (if keyed separately)

After a Break-In: Securing Your Home Again

A break-in is traumatic. Once police have completed their report and you’re cleared to re-enter, here’s the sequence of steps we recommend:

1. Document before touching anything. Take photographs of all damage for your insurance claim before repairs begin.
2. Call your insurance company to report the incident and begin the claims process.
3. Have a locksmith assess all entry points — not just the one used by the intruder. Often, break-ins reveal that multiple points of entry have inadequate hardware.
4. Replace all compromised locks immediately. Even a lock that appears undamaged may have been picked, bumped, or otherwise compromised without visible evidence.
5. Upgrade the strike plates on all exterior doors with 3-inch screws. Most break-ins exploit weak door frames, not the lock itself.
6. Consider a door reinforcement kit for any door that was kicked in. These hinge-and-frame reinforcement systems make kick-ins nearly impossible.
7. Review your other security layers: lighting, window locks, alarm system, and outdoor camera coverage.

Smart Locks in Canada: Are They Worth It?

Smart locks have become popular in Toronto condos, semi-detached homes, and rental properties. They offer genuine convenience, but they come with considerations that aren’t always discussed in marketing materials:

What smart locks do well

• Keyless entry via PIN, app, fingerprint, or fob
• Temporary access codes for guests, Airbnb renters, or tradespeople
• Auto-lock after a set time (so you never forget to lock up)
• Remote lock/unlock and access logs from your phone
• Integration with home automation systems (Google Home, Amazon Alexa, Apple HomeKit)

Canadian-specific considerations

• Battery performance in winter: All smart locks run on batteries. At −20°C, battery life can drop significantly. Choose a model rated for cold climates and check the batteries before winter every year.
• Connectivity gaps: Many smart locks require a Wi-Fi hub near the door. Older Toronto homes with thick walls or older wiring may have dead zones near exterior doors.
• Condo restrictions: Many Toronto condo corporations have bylaws restricting lock replacements or requiring specific hardware. Check with your building management before installing a smart lock.
• Backup physical key: Always choose a smart lock that includes a physical key override. If the battery dies or the electronics fail in winter, you still need a way in.

Our recommendation

A smart lock is an excellent addition to a home’s security system, but it should complement, not replace, a quality Grade 1 deadbolt. We recommend installing a smart lock on one door (typically the front) while maintaining a standard high-security deadbolt on secondary entrances.

Frequently Asked Questions

How long does it take to rekey a home’s locks?

Rekeying a typical Toronto home (3–5 exterior lock cylinders) takes approximately 45–75 minutes. The locksmith will provide you with a new set of keys for each door at the end of the appointment.

Can you rekey locks so that one key opens all doors?

Yes. This is called a master key or keyed-alike system. We rekey all your cylinders to accept the same key. Most homeowners prefer this — it means one key opens the front door, back door, and any other exterior locks.

I’m locked out of my home. How quickly can you get here?

Our average response time across Toronto is 20–40 minutes. For true emergencies (young child inside, adverse weather), let us know when you call and we prioritize accordingly.

Will you damage my door or lock when opening it?

No. We use non-destructive entry techniques. Lock picking and bypass tools allow us to open your lock without drilling or damaging it. Drilling is only used as a last resort for severely jammed or seized hardware.

What locks do you recommend for Toronto homes?

For front doors, we typically recommend Schlage Grade 1 deadbolts paired with reinforced strike plates. Schlage cylinders are pick-resistant, bump-resistant, and widely available in Canada. For a step up in security, Medeco and Mul-T-Lock offer high-security cylinders with restricted key duplication.

Do you work on older Toronto homes with non-standard door configurations?

Yes. We work on Victorian-era homes in The Annex and Cabbagetown, post-war bungalows in East York and Etobicoke, modern condos downtown, and everything in between. Non-standard door thicknesses, mortise locks, and antique hardware are all within our experience.

Can you make a copy of a restricted key?

If your key is marked “Do Not Duplicate,” we respect that — it indicates a restricted key system. For legitimate needs (adding a household member, replacing a lost key), we coordinate with the key system’s managing locksmith to issue additional authorized copies properly.
