The choice of locks and doors go hand-in-hand. A high security lock on a wood hollow core door, or the opposite is money, time, and effort wasted. Such combinations give a very false sense of security and provide little to no security at all.

Types of Doors

Important Make sure your new doors are steel-edged (rather than wood-edged) as these doors offer much more security.

There are plenty of accents available to help fully customize your entryway to your needs and desires.

Note When choosing a new door consider the security cons of certain accents. While a design might be aesthetically pleasing, it could be detrimental to properly securing your new home


 Security Lock Terms.

Dead latch
A dead latch has two bolts - a main spring operated bolt and a smaller auxiliary bolt. The small bolt triggers the main bolt to automatically enter the dead latch position. When you go out, you simply close the door behind you - you don't need to use your key to lock the door.

Dead lock
Dead locks can only be operated by key from outside and by turn knob on the inside. Unlike a dead latch there is no automatic locking. This means that unless you lose the key, you cannot lock yourself out.

Dead bolt
Double cylinder dead bolts have a single bolt that connects to the strike plate in the door frame. They are opened by a key from both the outside and the inside. Dead bolts are often used as an auxiliary lock for added security if the existing lock is a Key-in-Knob lock.

Night latch
A night latch is spring operated latch that can be opened using a key outside and the turn knob inside. Some night latches have a nip that allows you to use the hold back feature when you are inside your home.

A keyed alike system allows you to use a single key for a number of locks - one key for your door locks and another for your window locks.

Positive Dead locking
By turning the key you drive the bolt to either the locked or unlocked position. Positive deadlocking guarantees the lock is deadlocked overtime.

Back set
If you are installing a door lock yourself, you will need to know about a lock's back set. It is the horizontal distance from the edge of the door to centre line of the inside or outside cylinder.

Surface Mounted and Mortise Locks
A surface mounted lock means that the locking mechanism is fixed to the surface of the door. The screws that fix the lock to the door can be either visible or concealed, depending on the type of lock installed. Most domestic door locks are surface mounted locks. A mortise is the opening made in the edge of the door that the locking mechanism fits into. Mortise locks are most often installed on sliding patio doors or security doors.

A rebate is the step that is cut out from the edge of the door or the door frame. Rebates are used to ensure the door seals properly when closed, the lock works for cosmetic reasons. Rebates are generally used on double doors or french doors.

Face or Side Fixing
Many security locks can be installed on either the face or side of the window frame.

Face fixing means that the screws that fix the lock to the window are 90° to the sash.
Side fixing means the screws are parallel to the sash.

One Way Screws
If your customers are planning to install window locks themselves, you should advise that the most locks are supplied with both conventional and security, one way screws. These screws are specifically manufactured and have specially shaped heads that can't be removed by conventional screwdrivers. All window locks should be installed and tested by using the normal screws and then when they are working effectively, these screws should be replaced with the one-way screws for added security. The lock is then permanent and can't be removed with a standard screwdriver.


"Dead Bolt Locks" are advocated for all exterior doors ( see definition ).   The effect of a dead bolt lock is that if a criminal does manage to get into your home or business, they won't be able to just open the front or back door and walk out with your property, because they won't be able to unlock the door without they key!

 Unfortunately windows are a favourite method for breaking into homes and businesses.   Usually the locks are flimsy and easy to manipulate or force.   The criminals will chose a window at the side or rear of the premises out of sight and go to work.   It is rare for the glass to be broken as this makes too much noise and can attract neighbours.   By using good quality window-locks on ALL windows, that can only be opened using a key you increase your security to a level recommended by the The Neighbourhood Watch Association and the SA Police.
