Break-in victim? Your complete guide

Coming home to a door that won’t close straight, a cracked frame or a scratched cylinder is breathtaking. Whether you’re in a walk-up on the Plateau Mont-Royal, a duplex in Ahuntsic, a house in Westmount or an apartment building in Saint-Léonard, the reaction is often the same. First we wonder if anyone’s still inside, then we think of loved ones, papers, keys and insurance.

The right reflex is not to rush for the handle. It’s about regaining control in the right order, then securing what’s given way for the long term.

In Montreal, this vigilance is no exaggeration. According to Statistics Canada on residential break-ins, Montreal was among the metropolitan areas with the highest rates of residential break-ins in 2002. Rates have fallen since then, but Montreal’s terrain remains distinctive. Poorly aligned building doors, old wooden frames, inconspicuous rear entrances, winter-worn hardware. These are very real vulnerabilities.

We’ve been in this business for over 20 years. Our service is fully bilingual, to support both French-speaking and English-speaking customers in the greater Montreal area. We’re also BSP Certified (#20073700), with full security clearance and verification, which counts when you need to act quickly after a break-in.

Victim of a break-in? Your action plan starts here

In the field, the same scenario is often repeated. A tenant in LaSalle comes home from work, sees the front door ajar, and at first thinks it’s a poorly closed door. A homeowner in Anjou notices that the bolt suddenly snags, then discovers lever marks on the strike plate. In both cases, the confusion lasts a few seconds. After that, it’s all about simple gestures, in the right order.

Breaking and entering doesn’t always leave a broken door. In Montreal, especially in the older buildings of the Plateau, Montreal North or Westmount, I often see doors that appear almost intact, when the real damage is in the alignment of the frame, the striker plate torn off, or the cylinder manipulated.

What to do right away

The first objective is simple. Stay safe and avoid covering your tracks.

• Don’t go inside if anything seems amiss. A door ajar, an unusual light, a window moved or a noise inside is enough to keep you outside.
• Avoid touching the lock, handle or frame. Even an instinctive gesture can complicate police work.
• Be prepared to document the site later. Photos, videos, summary list of damage, missing items.

Rule of thumb: after a break-in, the priority isn’t the lock. It’s your safety, then preserving the scene.

When the authorities give you the go-ahead, you then have to close the breach. Not with an improvised tape repair or a hastily-installed screw. A door that has been forced open has often lost its real strength, even if it appears to be standing.

If you need a quick turnaround in Montreal, Laval or Longueuil, it’s best to use our locksmith contact service in Montreal, Laval and Longueuil to organize access security without wasting time.

The right frame of mind

After a break-in, many people “just want a new lock”. That’s understandable. But if the frame is cracked, the door has worked, or the hinges have taken a beating, changing just the cylinder doesn’t solve the real problem.

Good troubleshooting always starts with a complete diagnosis. The lock, yes. The frame, the strike plate, the anchoring screws, the state of the door, the rear access and the lighting. This is what gives real security, not just the impression of a lock.

What is breaking and entering, and how do you spot it?

In legal and practical terms, breaking and entering does not necessarily require spectacular destruction. The central idea is that intrusion is achieved by physical or technical forcing of the access point.

According to the definition quoted for article 350, breaking in includes physical or technical intrusion, and techniques such as bumping can open 90% of standard pin locks in a matter of seconds. This is precisely why access can be compromised with little visible damage.

What is often mistaken for a simple slammed door

A slammed door poses an access problem. A forced entry poses a problem of security, evidence and insurance.

The difference is in the details. A tired lock can jam. An ill-fitting door can break in winter. On the other hand, when the cylinder has been tampered with, when the strike plate has backed into the wood, or when the bolt no longer aligns after a shock, we’re no longer in the business of simple repairs.

Here are the signs that merit immediate inspection.

• Lever marks on frame. Look for paint chips, wood compression or deformation near the strike plate.
• Cylinder scratched, pierced or abnormally loose. Some manipulations leave few traces, but the cylinder clearance changes.
• Twisted bolt or sudden catch. If the key turns incorrectly after the incident, the mechanism may have been forced.
• Debris near the threshold. Wood, metal, bits of hardware or splinters of screws are very telling clues.
• Window moved, broken or opened without explanation. In many ground-floor dwellings in Ahuntsic or Montréal-Nord, the intruder uses a secondary access rather than the main door.

The discreet traces that many do not see

In buildings in LaSalle and Saint-Léonard, I regularly see doors that still close, but badly. The gap between leaf and frame is no longer even. The bolt scrapes. The handle seems normal, but the weak point has become the striker attachment or the wood fiber behind the plate.

A lock may look “functional”, but still be unsuitable for protecting your home.

The same is true for shared entrance doors. When a shared entrance takes a beating, it’s not just the door that’s the problem. It’s often the locking hardware, the strike plate, or even the access solution itself that needs to be reviewed. If you want to understand the precise role of this part in the door’s resistance, the page on the door strike and its mechanical importance helps you to see where the break-in often actually begins.

The useful reflex before any repair

Inspect visually. Do not disassemble. Don’t clean the area. And don’t assume there’s no break-in just because “the lock doesn’t look broken”.

Fine techniques sometimes leave fewer traces than a kick. This is precisely what makes an assessment by an experienced locksmith so important after the police have passed.

The 3 crucial steps to take in a post-burglary emergency

When the adrenaline’s pumping, people often do things out of order. They call a relative, pick up objects from the floor, try to close the door, and only then think of the police. After a break-in, you need to reverse this reflex.

1. Put yourself out of harm’s way

If the door is open, if a window has been forced open, or if anything looks out of place, don’t go in. Stay in a safe place. At a neighbor’s house, in a nearby shop, in your car if you’re nearby and safe.

If you think someone may still be inside, call 911 immediately. Nothing in the home is worth the risk of confrontation.

• Stay away from the entrance.
• Observe without interfering.
• Avoid letting other people in.

In Montreal’s plexes, especially on the Plateau or in Ahuntsic, a well-meaning neighbor sometimes wants to “check it out”. This is a bad idea. They can endanger themselves and contaminate the scene.

2. Make the official report without delay

The police report is the starting point. Without it, everything becomes more complicated, especially insurance and the chronology of events.

In Quebec, tenants must notify their landlord and the police within 24 hours of discovering a break-in for insurance to be activated, and the TAL notes that 40% of rental claims are complex due to late reporting. In practice, the sooner you report a claim, the better protected your case will be.

3. Document before refurbishing

When the police have finished their work on site, take clear photos.

Above all, document the following.

• The point of entry. Door, frame, lock, window, screen, patio door.
• Indirect damage. Cracked woodwork, torn screws, bent door closers, damaged mouldings.
• The immediate interior. Open drawers, objects on the floor, signs of rummaging.
• Missing or damaged goods. Keep the list simple, even if it’s incomplete at first.

Workshop tip: take wide shots first, then close-ups. Insurers and police officers understand the scene better when they see the whole before the detail.

What tenant and landlord each have to do

For the tenant, the first practical obligation is to report the situation promptly. For the owner or manager, the priority is to restore the property to a safe condition.

In the apartment buildings of Montréal-Nord, Anjou or LaSalle, the sticking point is often a simple question. Who pays for what? Generally speaking, the owner is responsible for restoring safety to damaged access, except in cases of proven negligence. But in the field, I always advise against wasting time arguing the point until you’ve secured the site.

Here’s the useful order.

1. Police
2. Notice to owner or manager
3. Photos and damage list
4. Opening an insurance file
5. Door security

When you need to close a forced entry quickly, it’s better to use an emergency locksmith for immediate intervention rather than a makeshift repair. A door that is temporarily “held” does not offer real protection for the following night.

What not to do

A number of gestures complicate the rest unnecessarily.

• Don’t change the lock yourself until the police have arrived, unless the immediate danger has been confirmed.
• Do not throw away damaged parts. Keep them if they have been removed.
• Don’t minimize frame damage. This is often where the door remains vulnerable.
• Don’t wait until tomorrow to declare if you’re a tenant.

The good news is that once these steps have been taken, the situation becomes very real again. We move from panic to repair, then to prevention.

Why call in an emergency locksmith after a break-in?

A broken door isn’t just a broken lock. It’s a weakened assembly. The leaf may have moved, the frame may have cracked, the strike plate may no longer hold properly, and the hinges may have become loose.

This is where professional intervention makes all the difference. Improvised repairs often give a false sense of security. The door closes, so you think the problem is solved. But at the first touch of a shoulder or lever, it gives way again in the same place.

What an emergency locksmith really checks

After police clearance, the serious work begins with a mechanical diagnosis.

In particular, we check :

• Condition of cylinder and deadbolt
• The strength of the frame and striker area
• Door alignment after impact
• Hinge and anchor screw resistance
• The ability to secure or replace immediately

In some cases, an effective repair is all that’s required. In others, the cylinder, strike plate or even the entire lock needs to be replaced. If the frame is too badly damaged, the right choice is to first stabilize it, then schedule a more extensive overhaul.

Why DIY rarely works

A panel screwed in the wrong way, a long screw added without reinforcement, or a basic lock installed in a hurry often cost more afterwards. We then correct the problem a second time, and sometimes have to replace a door that could have been saved with a clean first intervention.

In Montreal, winter adds yet another problem. A door already out of alignment after a break-in works even harder with cold, humidity and freeze cycles. What “just about closes” in the evening can completely block a few days later.

A successful emergency repair is not just about closing the door. It must make the resistance of the access point consistent with the level of risk.

For this type of situation, a mobile service with 20-Minute Response Time is the best way to prevent a home or business from being left open too long. If the lock or frame has been affected, the most logical thing to do is to organize a lock change adapted to the actual condition of the door, rather than replacing a single part at random.

From reaction to prevention: how to armour your home

A break-in often leaves a clear conclusion. The hardware in place was sufficient for daily routine, not for a real attack. This is often the case in apartments on the Plateau, houses in Montreal North, duplexes in Ahuntsic and certain buildings in Westmount, where the door is beautiful and heavy, but poorly reinforced at the critical point.

National figures remind us that this is still a major issue. In 2024, break-ins accounted for 13% of the Crime Severity Index in Canada. Even with a fundamental drop, the volume remains significant enough to justify security choices that go beyond the basic lock.

What really works on a residential door

The first trade-off is to understand that a good lock doesn’t make up for a bad door. You have to think in layers.

• The cylinder must resist picking, drilling and fine handling.
• The deadbolt must enter deeply and cleanly into a reinforced strike plate.
• The frame must withstand the stress without bursting.
• Hinges must be able to withstand stress, especially on heavy or old doors.

When a customer asks me what to choose, I always look at the whole before the brand. But certain product families stand out.

High security locks and key control

For a primary residence, a condo or a dwelling where the control of duplicates counts, the most serious options remain high-security cylinders with restricted key control.

This is where brands like Abloy and Medeco really come into their own. It’s not just technical strength that makes them attractive. It’s also the fact that the key can’t be duplicated at the counter of an ordinary hardware store. For an owner, manager or family who has lost track of duplicates over the years, this makes a real difference.

The compromise is simple. The initial cost is higher, but access control is much better.

Smart locks and keyless access

Smart locks have their place, but not in every situation. For an Airbnb, a family home or a door where several people enter at different times, a model like Schlage Encode or certain Weiser solutions makes access management much simpler.

Good use doesn’t mean “replacing all safety with electronics”. It’s about combining convenience with a serious mechanical foundation.

What I recommend in practice:

• For a busy year-round home. Well-chosen smart lock with good deadbolt and clean installation.
• For rental properties with frequent turnover. Useful keypad for changing codes without re-keying.
• For doors exposed to cold and humidity. Choose a model that can withstand Quebec winters and keep the door snug.

The forgotten weak point: the door itself

Many break-ins succeed at the frame, not at the heart of the lock. In older buildings in Anjou or Saint-Léonard, I still see strikers fixed with screws that are too short in tired wood. The bolt is good, but it works in weak wood.

Useful reinforcement often includes :

• Striker reinforcement plate
• Suitable anchoring screws
• Continuous hinges on some doors
• Leaf alignment adjustment
• Replacing worn hardware

If you’re comparing options for a real qualitative leap, the simplest reference to remember remains the high-security deadbolt for residential doors. This is often the most cost-effective base before adding other layers.

Comparison of residential locking solutions

Not worth the investment

Some purchases are visually reassuring, but make little difference to actual resistance.

• A simple “smart lock” on a misaligned door
• A camera without point-of-entry reinforcement
• A second lightweight bolt on an already cracked frame
• A new decorative handle without a serious deadbolt

The best improvement isn’t always the most visible. Often, it’s the combination of cylinder, strike, anchoring and alignment that makes the real difference.

For residences, the healthiest prevention remains a layered approach. A good lock. A door that holds. A reinforced frame. And, depending on the context, a camera or additional access control.

Advanced security for homes and businesses in Montreal

In a rental or commercial building, security never stops at the front door. Common accesses, deliveries, former occupants, employees, technical areas and emergency exits all need to be managed.

This is particularly true in the buildings of Ahuntsic, the commercial arteries of the Plateau, or the mixed-use buildings of LaSalle, where the same door is used for several purposes during the day.

According to the SPVM’s data on the rise in 2025, residential burglaries have increased in this segment, reinforcing the importance of proactive solutions such as access control for common areas.

Access control for buildings and offices

Access control removes a classic problem. The uncontrolled circulation of keys.

With well-integrated readers, fobs, cards or electric strikes, a manager knows who is entering and can remove access without changing all the hardware. For this type of installation, we commonly work with Assa Abloy and Corbin Russwin components when the site configuration requires it.

In a multi-dwelling, this system has three main practical advantages:

• Quickly remove a former occupant’s access
• Separate common and technical areas
• Reduce dependence on copies of keys in circulation

CCTV and intercom

A camera does not replace a lock. It completes the strategy.

For a shop window or apartment block, CCTV helps document comings and goings, verify an incident and deter opportunistic behavior. Intercom systems, on the other hand, reduce the risk of “habitual” opening to the wrong people, which is still often the case in communal entrances.

In a building, the flaw isn’t always the private door. It’s often poorly controlled collective access.

Commercial hardware and compliance

Businesses have additional obligations. A panic bar, door closer or electric strike is not just a safety measure. They must also comply with building and fire safety requirements.

This is where the Dorex, LCN, Assa Abloy or Corbin Russwin brands come into play, depending on door type and use. For an exit, a poorly chosen panic bar can create a compliance problem. For a main door, a poorly adjusted closer will let the door close incorrectly all winter long, with loss of safety and energy efficiency.

Lock Aid Serrurier Montréal can be called in as a practical option for installing or upgrading hardware, access control, intercoms and video surveillance in the greater Montreal area. The key is to choose a fitting that is compatible with the building, daily use and applicable RBQ and fire safety regulations in Montreal.

Your peace of mind is our priority

After a break-in, the most useful decisions are rarely complicated. You need to secure the premises, protect your file, and then correct the actual weakness that allowed the intrusion.

True peace of mind doesn’t come from a hastily installed lock. It comes from an access that’s been properly redesigned, with hardware adapted to the building, neighborhood, use and climate of Montreal.

We’ve been doing just that for over 20 years, with a fully bilingual service for Montreal, Laval, Brossard, Longueuil and Terrebonne. Our team is BSP Certified (#20073700), with 24/7 Mobile Service and 20-Minute Response Time for emergencies when context permits.

For readers who want to delve deeper into the broader dimension of access protection, prevention and post-incident reflexes, there’s also a category dedicated to security, bringing together useful resources to consult at your leisure.

The right approach, at heart, is simple. Fix what’s broken. Strengthen what was weak. And don’t wait for the next incident to do it.

Frequently asked questions about break-ins in Montreal

Should my landlord have the lock replaced after a break-in?

In practice, yes, because a dwelling to which access has been forced no longer offers the peaceful enjoyment expected. The owner or manager must restore the dwelling to a safe condition, except in special situations where gross negligence on the part of the tenant is clearly established.

In the field, my advice is not to let this discussion delay securing. First, protect access. Then clarify the breakdown of costs with insurance and supporting documents.

Does insurance pay locksmith costs?

In many cases, homeowner’s policies cover burglary damage and reasonable emergency repairs. What makes the difference is the quality of the file.

Always keep :

• Police report
• Damage photos
• Detailed invoice
• List of affected assets
• Exchanges with the owner or manager, if you are a tenant

A clear invoice that distinguishes between security upgrades, hardware replacement and visible repairs helps a lot.

Is a high-security lock tamper-proof?

No. No serious lock should be sold as “tamper-proof”. The right professional language is resistance, delay, complexity, noise and discouragement.

A well-installed Medeco or Abloy makes the intruder’s job much harder. Add a reinforced frame, a good strike plate and a properly adjusted door, and you can turn a simple target into a much more difficult access.

Should I change only the cylinder or the entire lock?

It depends on the actual damage. If only the key management is compromised, a change of cylinder may suffice. If the bolt, housing, strike or alignment have suffered, replacing only the cylinder often leaves a weak point in place.

Are smart locks right for Montreal?

Yes, if they’re well chosen and properly installed. The key point in Montreal is tolerance to cold, humidity and doors that work in winter. A smart lock installed on a misaligned door will cause problems. On a sound door, with the right hardware, it can be very practical.
