Deadbolt locks play a vital role in keeping your home, its contents, and inhabitants safe and secure. But what is a deadbolt lock and what's the best one to get? Let's take a look...

What is a deadbolt lock?

Deadbolt locks are thicker and heavier than regular door locks, typically made of steel, bronze, or brass, fitted into the edge of the door frame.

They are often found on the external front and back doors of residential homes and fall into three main types:

  • Single-cylinder (keyed on one side and operated by a knob or thumbturn on the other)

  • Double-cylinder (keyed on both sides)

  • Lockable thumbturn (a mix of both)

How do you lock a deadbolt?

Deadbolt locks are fitted within the material of the door itself - rather than on the surface of the door.

A deadbolt lock has a solid rod that extends deeper into the door frame than a regular, spring-latched door lock, offering greater security.

The solid rod slots into the door frame when locked. This retracts when in the unlocked position.

What is the best deadbolt lock?

The best deadbolt lock is one which is Kitemarked to British Standard BS-3621. You'll find this on the faceplate of the lock itself.

A deadlock with this Kitemark means it has been tested against burglary techniques, including drilling.

Also, look for a deadbolt lock with a reinforced strike plate, as this offers added security against potential intruders. The strike plate is the part that the solid rod enters (in the door frame) when the door is in the locked position. Reinforcing it therefore makes forced entry even harder.

A qualified locksmith will be able to help advise you on the best deadbolt lock for your needs.
