3 Common Types of Locks

Choosing the right type of lock can help make a more secure home for your family.  Luckily, there are several basic types of locks to choose from, including: knob locks, multi-point and rim automatic dead latch.

Here are the 3 common types of locks:

Knob Locks

One of the most common type of door locks, knob locks are used on all kinds of doors; front door, bedroom door, garage doors or rear patio doors. These locks have knobs on both sides One side has a lock and the other side has a key hole to unlock the door. When replacing a knob lock, be sure to determine which side of the door the lock is on — you’ll need a right-hand knob lock for a doorknob on the right side of the door, a left-hand knob lock for a doorknob on the left side of the door. Because the locking mechanism is inside the knob (instead of the door) it can be easily broken with a hammer, wrench or rock and shouldn’t be the main security lock on a front door.  Source:  Angieslist


A multi-point locking system has a minimum of three locking points that all lock simultaneously by the turn of a key. These are most common on patio or French doors – typically uPVC doors – and less common for main entrance points. Some properties may use such a lock on the principle point of entry, though, and insurers will assess risk accordingly. Source:   GoCompare

Rim Automatic Dead Latch

Front door type lock that locks when the door is shut, it often looks like a brass metal box on the inside of the door. It is fitted to the inner surface of the door as opposed to being set into the edge of the door like a mortice lock. Most rim locks will not meet the spec though as very few have a locking handle on the inside. This is needed to prevent thieves making an easy exit. Source:  MoneySavingExpert
