Components and characteristics

3 – The rotary knob

Button that activates the bolt on the inside of the door to bar or unlock the lock.

4 – The striker

The striker plate consists of a metal plate with an opening, attached to the hole in the door frame into which the bolt is inserted to lock the door or keep it closed.

5 – The rosette

Decorative plate surrounding the handle.

6 – The axis

The axis is the metal rod which connects the two parts of the handle and activates the bolt by turning.

7 – The headrest

The face plate is a metal plate provided with an opening, which must be fixed on the hole made in the thickness of the door, and through which the bolt passes.

8 – The latch bolt

Solid metal cylinder intended to keep the door closed when inserted into the strike plate. The bolt is operated by the handle when opening the door.

Installation: how do we do it?

Here are some general guidelines to help you install door locks and handles.

Measure the thickness of the door. Handles and locks can be installed on doors 1 3/8″ to 1 ¾ » thick.
If you buy a machined door, that is to say already perforated to receive the handle and the lock, know that these doors are standard. Be sure to make the strike hole at the same height as the pre-drilled hole on the door.
If you buy a non-perforated door, be sure to make the holes for the handle and for the strike at the same height, which is normally 36″ (at the center of the hole) for residential doors and 39 3/4 po for commercial doors. A template is included with the handle in order to drill the holes correctly.
For the replacement of an exterior door, it is preferable to select the handle and the lock at the same time. When ordering, the manufacturer will drill the holes to the correct dimensions.

It may be necessary to re-screw and lubricate locks and handles occasionally. Lubricate them only with a lubricant specially formulated for locks and handles, as popular lubricants could damage the mechanisms.

4 Choses à savoir avant de changer la serrure de porte

Whether you want to change your front door lock to increase the security of your property or because it is damaged, having a clear idea of the options available to you will help you make a good decision.

Here are 4 things to consider for a successful lock change!


If changing the lock of a door may seem trivial, you should know that not all locks are suitable for all doors. Thus, it is important to take certain technical aspects into consideration before making the purchase. For example :

What is the size of the previous lock?
What are the dimensions of the elements of the current mechanism (locking points, cylinder, handle, etc.)
How thick is the door?
What materials is the sash made of?
What direction does the door open?
Your locks are in good condition, but you want to increase the security of your home or commercial building? This is a criterion that must be taken into account during your research. Indeed, not all locks offer the same degree of protection. To this end, knowing the requirements of your insurance company on the issue could help you find the most appropriate lock.


If your lock is malfunctioning, only one of its elements may be at fault. It is then possible to replace only the part in question. Do you just want to change the key? Replacing only the barrel (barrel or cylinder; the part where the key is inserted) is a simple and economical solution. If you wish, there are even different locking options available to you, such as the disengageable cylinder which allows the door to be opened even if a key is introduced inside the house.

However, if you have decided to change the locks to strengthen the security of the premises, replacing the cylinder will not be enough. The best avenue will then be to opt for a lock model with several locking points, thus offering optimal security.

Choosing the right door lock is of great importance, especially since depending on the situation, some types of locks will work better than others.
