10 Locksmith Myths That Could Put Your Home or Business at Risk

Separating Fact from Fiction About Locks, Keys, and Home Security

When it comes to home and business security, there is no shortage of advice online.

Friends offer tips.

Neighbours share stories.

Social media is full of "security hacks."

Unfortunately, not everything you hear about locks and home security is true.

Some myths seem harmless.

Others can leave your home or business more vulnerable than you realize.

At Kevin's Mobile Locksmith, we've spent years helping homeowners and businesses throughout Niagara Falls, Welland, St. Catharines, Port Colborne, Fort Erie, Thorold, Fonthill, Lincoln, Grimsby, and communities across the Niagara Region improve their security. Along the way, we've heard just about every locksmith myth imaginable.

Let's separate fact from fiction.

Myth #1: "If My Locks Still Work, They're Fine."

Just because a lock turns doesn't mean it's providing the security it should.

Locks experience wear every day.

Over time:

• Internal components wear down.

• Keys become loose.

• Deadbolts stop aligning properly.

• Hardware weakens.

Routine inspections can identify problems long before they become emergencies.

Myth #2: "I Don't Need to Rekey After Buying a House."

This is one of the biggest misconceptions among new homeowners.

When you purchase a home, you rarely know exactly how many key copies exist.

Previous access may have been given to:

• Family members

• Friends

• Contractors

• Cleaning services

• Dog walkers

• Previous tenants

Rekeying ensures old keys no longer work while allowing you to keep your existing lock hardware.

Myth #3: "Hiding a Spare Key Outside Is Safe."

Many homeowners still hide spare keys under:

• Welcome mats

• Flower pots

• Fake rocks

• Mailboxes

Unfortunately, these are the first places someone attempting unauthorized entry is likely to check.

A trusted family member, secure lock box, or keyless entry system is generally a much safer solution.

Myth #4: "A Bigger Lock Always Means Better Security."

Lock size alone doesn't determine security.

Proper installation matters just as much.

A quality deadbolt installed correctly on a properly reinforced door provides significantly better protection than an oversized lock installed incorrectly.

Your entire entry system works together.

Myth #5: "Smart Locks Aren't Secure."

This myth continues to circulate despite significant advances in technology.

Modern keyless entry systems often include:

• Encrypted communication

• Temporary access codes

• Auto-lock features

• Activity logs

• Backup key access

When professionally installed and used correctly, smart locks can provide excellent security along with added convenience.

Myth #6: "Locksmiths Only Help During Emergencies."

Many people only think about locksmiths after they're locked out.

In reality, professional locksmiths also provide:

• Lock installation

• Lock repair

• Rekeying

• Deadbolt upgrades

• Master key systems

• Patio door lock service

• Duplicate keys

• Commercial security solutions

Preventive security improvements often help homeowners avoid emergencies altogether.

Myth #7: "Every Exterior Door Is Equally Secure."

Not necessarily.

Many homes have weaker secondary entry points such as:

• Patio doors

• Garage entry doors

• Basement walkouts

• Side entrances

Your home's security is only as strong as its weakest door.

Every exterior entrance deserves regular inspection.

Myth #8: "Making Lots of Spare Keys Makes Life Easier."

It can also make managing security much harder.

If you don't know:

• How many copies exist,

• Who has them,

• Or where they are,

your home's security may be compromised.

Maintaining control over duplicate keys is an important part of protecting your property.

Myth #9: "Commercial Locks Never Need Maintenance."

Business locks often experience far more daily use than residential hardware.

Without maintenance, commercial locks may develop:

• Alignment issues

• Worn cylinders

• Difficult operation

• Reduced reliability

Routine inspections help businesses avoid unexpected disruptions and expensive emergency repairs.

Myth #10: "Security Is Something You Only Think About After a Break-In."

One of the most expensive security mistakes is waiting until something goes wrong.

The best time to improve security is before you need emergency service.

Simple upgrades like:

• Rekeying

• Deadbolt installation

• Patio door lock improvements

• Keyless entry

• Master key systems

can significantly improve both convenience and peace of mind.

Good Security Is Built in Layers

Professional locksmiths don't simply recommend one product.

They evaluate the entire property.

Effective security often includes:

• Quality lock hardware

• Proper installation

• Secure door frames

• Deadbolts

• Patio door protection

• Key management

• Good outdoor lighting

• Regular maintenance

Every layer works together to create better protection.

Technology Has Changed Home Security

Homeowners today have more choices than ever.

Options include:

• Traditional keyed locks

• Smart locks

• Keypads

• Electronic deadbolts

• Restricted key systems

• Master key systems

Choosing the right solution depends on your property, lifestyle, and security priorities.

Prevention Is Almost Always Less Expensive

Waiting until:

• A key breaks,

• A lock fails,

• Someone loses a key,

• Or a break-in occurs,

often results in higher costs and greater inconvenience.

Routine maintenance and proactive upgrades help reduce the likelihood of unexpected emergencies.

Work With a Trusted Local Locksmith

Security isn't just about products.

It's also about having someone you trust.

A local locksmith understands:

• Niagara homes

• Commercial buildings

• Local neighbourhoods

• Common lock systems

• Seasonal challenges

Building a long-term relationship with a trusted locksmith makes future service faster and more efficient.
