Accurate measurements are the key to a successful installation, ensuring your transition to a smart door lock system is seamless and secure.

These are essential tools as we need to properly take the correct (approximate) measurement of your door lock configuration. 

Step 1: Measuring the door edge to door handle (backset) 

  1. Take out your measuring tool (tape or ruler) and place the tip of the measuring tool at the edge of the door to the center of the door lock (where the key hole is located). 
  2. Take a photo and make sure that the measuring tape and the numbers are visible. If needed, take the photo closer to the door lock or zoom in a bit once ready.

When you submit the size inquiry form, make sure this is done the way it is illustrated above. 

Step 2: Measuring the mortise width 

Mortise width varies from one door lock configuration to another such as swing door type mortises are usually wide while sliding door mortises are thin and narrow. Which is why it's important that you carefully take its measurement as all measurements are taken into consideration in providing recommendations. 

In measuring the mortise width, you need to measure only one point of the width to another point. Make sure to place the measuring tool right in the specific area. 

Final output should look like the photo reference below:

If the area is too narrow and thin, especially for sliding door mortises, you can just place the measuring tool in the area to make sure that the tip of the measuring tool is placed in the edge.

Step 3: Measuring the mortise height

Since each door lock configuration varies from one design to another, it also goes the same to the mortises. Some mortises are embedded inside the door frame, some mortises have longer height than the usual mortises, while others are shorter especially for the latch type mortises. 

For the regular mortises, you can follow the photo reference below.

For the embedded type mortises which usually present in a multipoint lock setting, customers can provide the reference diagram of their existing mortise. For some, they took out the entire set and took a photo of the mortise itself. In many cases the customer does not opt in removing hence our Tech Team has a very specific recommendation on this kind of setup. 

If you have an existing multipoint lock mortise, you need to make sure that it is mentioned when you submit the size inquiry form and provide additional photo and details showing the entire door setup.

Confirming Compatibility for Your Smart Door Lock:

One of the most crucial aspects to address before purchasing your smart door lock is conducting a compatibility check with your front door, patio door, French door or other type of doors. While smart door locks are generally designed to work with a wide range of door types, there are certain situations where confirmation becomes essential. This step ensures a seamless installation and optimal functionality.

Smart door locks rely on various technical aspects and configurations, and these can vary from one door to another. To guarantee compatibility, it is imperative to have the technical aspects of your door lock configuration thoroughly reviewed by our dedicated Tech Team.

Exploring Potential Door Modifications:

It's crucial to recognize that our smart door lock mortises come with their distinct configurations and designs, which may necessitate adjustments on the customer's part.

In these cases, it's essential to consider the unique characteristics of your door and the specific requirements of the smart lock you intend to install. Door modifications can encompass a range of actions, such as altering the door's frame or structure to accommodate the smart lock's hardware or making adjustments to the mortise pocket to ensure a secure fit.

These potential door modifications should not be seen as obstacles but rather as steps taken to ensure the successful integration of your chosen smart door lock. By addressing these considerations, you are taking a proactive approach to guarantee that your smart lock installation proceeds smoothly and delivers the high level of security and convenience you expect.

By taking the time to assess compatibility, consulting with technical experts, and considering potential modifications, you pave the way for a seamless integration of your smart door lock. Accurate measurements are the linchpin in this process, serving as the cornerstone of a successful installation.
