The document explains the differences between deadbolts, deadlocks, and deadlatches as locking mechanisms. Deadbolts provide high security with various types available, including single-cylinder, double-cylinder, and keyless options. Deadlocks and deadlatches offer additional security features, with deadlocks requiring a key on both sides and deadlatches locking automatically upon closing.

2. WHAT ARE
DEADBOLTS?
A deadbolt is a locking mechanism that differs
significantly from the spring bolt locks found in
standard doorknobs. The defining feature of a
deadbolt is its ability to extend a solid metal bolt into
the door frame, creating a secure lock that is
resistant to forced entry. Unlike spring bolts, which
can be easily retracted by applying force to the bolt,
deadbolts require the rotation of the lock cylinder to
open and close. This makes deadbolts a more secure
option for exterior doors.

3. TYPES OF
DEADBOLTS
Single-Cylinder Deadbolt: Operated with a key
from the outside and a thumb turn from the
inside. Ideal for doors without glass near the
lock.
Double-Cylinder Deadbolt: Requires a key for
both the exterior and interior sides. Suitable for
doors with glass panels or when extra security is
desired.
Keyless Deadbolt: Utilizes a keypad, fingerprint
reader, or smart technology for entry. Offers
convenience and eliminates the need for physical
keys.

4. ADVANTAGES OF
DEADBOLTS
Increased Security: The solid bolt mechanism
offers superior resistance against forceful entry,
making it difficult for intruders to breach.
Durability: Constructed from heavy-duty
materials, deadbolts withstand physical attacks
better than most spring-latch locks.
Versatility: Available in various types to suit
different security needs and door styles.
Insurance Benefits: Installing deadbolts can
lower home insurance premiums as they are
recognized for providing enhanced security.

5. THE MECHANICS
OF DEADLOCKS
A deadlock is a lock mechanism that requires a key
to move the bolt into the locked or unlocked position.
Unlike a deadbolt, which can be unlocked from the
inside without a key, a deadlock is key-operated from
both sides. This feature provides an extra layer of
security, as there is no accessible turn knob from the
inside that could be manipulated to open the door.

6. BENEFITS OF USING
DEADLOCK
Enhanced Security: The key-operated mechanism
provides an extra layer of protection, making it
difficult for intruders to gain entry without the proper
key.
Prevention of Easy Entry: Unlike other locks,
deadlocks cannot be unlocked from the inside
without a key, reducing the risk of burglars easily
entering through a broken window.
Durability: Deadlocks are built to be sturdy and long-
lasting, providing reliable security for years to come.
Versatility: They can be used on various types of
doors, including front doors, back doors, and internal
doors, to secure different areas of your home.

7. INSTALLATION TIPS
FOR DEADLOCKS
Choose the Right Position: Install the deadlock at a
suitable height, typically around waist level, to make
it convenient to use and more secure.
Ensure Correct Alignment: The bolt should align
perfectly with the strike plate on the door frame for
smooth operation and maximum security.
Use Strong Screws: Secure the deadlock and strike
plate with strong, long screws that penetrate deep
into the door frame, providing better resistance
against forced entry.
Consider Professional Installation: If you’re unsure
about installing the deadlock yourself, hiring a
professional locksmith can ensure it’s done correctly
and securely.

8. HOW DEADLATCHES
WORK
A deadlatch is a locking mechanism that combines
the features of a spring bolt and a deadbolt. It is
designed to automatically lock the door when it is
closed, without the need for manual locking. This is
achieved through a unique mechanism that allows
the latch bolt to be retracted by a handle or knob
from the inside while requiring a key to unlock it from
the outside.

9. WHY CHOOSE A
DEADLATCH?
Automatic Locking: Deadlatches lock automatically
when the door is closed, ensuring your home is
secure even if you forget to lock the door manually.
Ease of Use: The ability to retract the latch bolt from
the inside with a handle or knob makes it easy to exit
your home quickly in case of an emergency.
Security Against Intrusion: The design of
deadlatches prevents common bypass methods,
such as loading, providing a higher level of security
compared to standard latch locks.
Versatility: Deadlatches can be used on a variety of
door types and are suitable for both residential and
commercial properties.

10. Locking Mechanism: Deadbolts require manual
locking using a key or thumb turn, whereas
deadlatches lock automatically when the door is
closed.
Ease of Exit: Deadlatches allow for easy exit from
the inside without a key, while deadbolts, especially
double-cylinder types, may require a key to unlock
from the inside.
Security Features: Deadbolts are known for their
strength and resistance to forced entry, making them
a preferred choice for exterior doors.
Application: Deadbolts are commonly used for front
and back doors that require high security, while
deadlatches are often used for internal doors or
doors with frequent access.
