Types of Deadlocks

A Simple Upgrade That Dramatically Improves Security.

Deadlocks provide a strong and reliable layer of protection for any property. Unlike standard spring-bolted locks, they cannot be easily forced open or picked, as a key is required to unlock them from either side. The door itself must be fully closed before locking, preventing accidental engagement and ensuring a secure seal every time. Double-cylinder deadlocks add an extra level of security by requiring a key on both sides, stopping intruders from reaching through windows or openings to unlock the door.

1

Single Cylinder

These have a key on one side and a turning doorknob on the other.

2

Double Cylinder

These operate with a key on both sides and usually no turning knob.

3

Vertical Deadbolts

Which resist the ability to pry open a door.

Maximise Security Without Compromising Safety

Smart ways to use deadlocks effectively and keep your home protected

While double-cylinder deadlocks provide excellent security, it’s important to consider safety. Always keep a key accessible near the door in case of an emergency, or only engage the deadlock when the house is unoccupied.

Deadlocks are most effective when paired with secure windows and sliding doors. Reinforce these entry points with tempered laminated glass, window locks, patio door pins, or track grips to prevent forced entry. For sliding doors, consider adding a deadlock or reinforced strike plate for complete protection.
