Introduction
Home security is surrounded by myths. Some have been passed from neighbour to neighbour for decades, while others come from outdated advice or clever marketing. Unfortunately, believing these myths can leave homeowners spending money unnecessarily or overlooking simple improvements that genuinely make a difference.
This A–Z guide separates fact from fiction, explaining the truth behind some of the most common misconceptions about locks, doors and home security.
A
Myth: Alarm Systems Prevent Every Burglary
Reality
Alarms are an excellent deterrent but are only one layer of security. Strong doors, quality locks and good physical security remain essential.
B
Myth: Burglars Only Break Windows
Reality
Many burglars simply try doors first. An unlocked or poorly secured door is often easier than breaking glass.
C
Myth: Composite Doors Can Never Be Broken
Reality
Composite doors are extremely strong, but their security still depends on the lock, hinges, frame and installation.
D
Myth: A New Door Automatically Means Better Security
Reality
A well-maintained older door fitted with modern security hardware can often be just as secure as a brand-new door.
Myth: Deadlocks Are Always More Secure Than Multipoint Locks
Reality
A quality multipoint locking system secures the door at several points along its height, whereas a traditional deadlock secures only one point. The overall level of security depends on the quality of the lock, the door, the frame and how well everything is installed.

E
Myth: Every Euro Cylinder Offers the Same Protection
Reality
Security varies enormously. Some cylinders provide basic protection, while others include anti-snap, anti-drill, anti-pick and anti-bump features.
F
Myth: French Doors Are Easy to Break Into
Reality
Modern French doors fitted with quality multipoint locks, secure shoot bolts and high-security cylinders provide excellent protection.
F
Myth: Fitting an Anti-Snap Cylinder Makes Every Door Secure
Reality
An anti-snap cylinder is an excellent upgrade, but it is only one part of the security system. Weak handles, poor door alignment, damaged keeps or a poorly fitted frame can still reduce the overall level of protection.

G
Myth: Good Locks Don't Need Maintenance
Reality
Locks, hinges and moving parts benefit from regular inspection and lubrication to reduce wear.
H
Myth: High-Security Locks Make Door Alignment Unimportant
Reality
Even the best lock performs poorly if the door is misaligned and the locking points cannot engage correctly.
I
Myth: Insurance Covers Every Type of Lock
Reality
Insurance policies vary. Some specify particular lock standards or require locks to be maintained in good working order.
J
Myth: A Jammed Lock Just Needs More Force
Reality
Forcing a stiff lock often damages the gearbox, handles or cylinder. The underlying cause should always be identified first.
K
Myth: Keeping a Spare Key Under a Plant Pot Is Safe
Reality
This is one of the first places an opportunist burglar may check. Spare keys should never be hidden outside in predictable locations.
L
Myth: Lubricating the Lock Will Fix Every Problem
Reality
Lubrication helps reduce friction between moving parts, but it cannot repair worn gearboxes, failed springs, damaged cylinders or poor door alignment. If a lock remains stiff after cleaning and lubrication, there is usually another underlying fault that should be diagnosed.

M
Myth: Multipoint Locks Never Fail
Reality
Like any mechanical device, they wear over time. Regular use, poor alignment and lack of maintenance all contribute to wear.
N
Myth: New Locks Last Forever
Reality
Every lock has a service life. Proper maintenance and correct door alignment help maximise its lifespan.
O
Myth: Old Doors Can't Be Made Secure
Reality
Many older doors can be upgraded with modern cylinders, security handles and improved locking hardware.
P
Myth: A Locksmith Will Always Recommend Replacing the Whole Door
Reality
An experienced locksmith will usually assess whether the existing door can be repaired or upgraded before recommending replacement.
Q
Myth: Quick DIY Repairs Are Just as Good as Professional Repairs
Reality
Incorrectly fitted locks or poorly adjusted doors often create bigger problems and reduce security.
Myth: Quality Locks Never Wear Out
Reality
Even premium locks experience wear after thousands of opening and closing cycles. Regular maintenance, good door alignment and early repairs help maximise their service life.

R
Myth: Replacing the Cylinder Fixes Every Lock Problem
Reality
Many locking problems are actually caused by worn hinges, poor alignment or gearbox wear rather than the cylinder itself.
S
Myth: Security Is All About the Lock
Reality
The lock is only one part of the system. The frame, hinges, handles, keeps and door condition are equally important.
T
Myth: Thicker Doors Are Always More Secure
Reality
A thick door fitted with poor-quality hardware can be less secure than a well-installed standard door with quality locking components.
U
Myth: uPVC Doors Are Easy to Break Into
Reality
Modern reinforced uPVC doors fitted with quality multipoint locks and anti-snap cylinders provide excellent levels of security.
V
Myth: Visible Security Doesn't Matter
Reality
Well-maintained locks, secure doors and good lighting can discourage opportunist criminals looking for an easier target.
W
Myth: Wooden Doors Are Less Secure Than Composite Doors
Reality
A solid timber door fitted with quality locks and correctly installed hardware can provide excellent security.
X
Myth: eXpensive Means More Secure
Reality
Price alone doesn't determine security. Independent testing, correct installation and suitability for the property are far more important.
Myth: eXpensive Always Means Better Security
Reality
Price alone is not a guarantee of security. Independent testing, recognised security standards, correct installation and suitability for the door are far more important than cost alone.

Y
Myth: You Only Need to Change Locks After a Burglary
Reality
Locks should also be changed after moving into a new home, losing keys or whenever key security has been compromised.
Z
Myth: Zero Maintenance Means Zero Problems
Reality
Even the best doors and locks require occasional maintenance. Cleaning, lubrication and early repairs help prevent unexpected failures and extend the life of the entire door system.

The Truth About Home Security
Good home security isn't about one expensive lock or the latest gadget. It's about creating a complete system where the door, frame, locks, hinges and hardware all work together. Regular maintenance, sensible upgrades and professional diagnosis when problems arise are often far more effective than simply replacing parts. Understanding the facts behind common security myths helps homeowners make informed decisions, improve the security of their property and avoid unnecessary expense.
