Yale Smart Lock YRD240 Review


Welcome to my Yale Smart Lock YRD240 Review.

Yale are one of the most famous lock companies in the world.

This smart lock, model YRD 240, is only one of many smart locks that this company makes.

The YRD 240 was first available in late 2013 and since then it has established itself as one of Yale’s most apopular and reliable smart locks.

My reviews are packed full of information which I want you to be able to read quickly and easily.

Therefore I have used lots of tables and other shortcuts to help you make the right decision as quickly as possible.

At- a- Glance Features

Below, I have created tables which show the different features that this device has. I have divided the features up into different tables to make it easier for you to read.

Those tables are;

(1) Basic Specifications (2) Methods of Opening (3) Software & Apps (4) Home Automation (5) Security & Lock

6) Design and (7) Installation

Each table has lots of information below it, which in order to save space, I have hidden. If you want to read it, then click on the “Read More” link.

Methods of Opening

[table id=126 /]

[expand title=”Read More” tag=”font color= green”]


The only method of opening this door is via the number pad. If you are using this lock on its own you can use and store up to 25 codes.

However, if you are using it as part of a wireless, home automation system, you can create and use up to 250 different codes.

The codes can be between 4 and 8 digits long.

 Other smart locks that use keypads


Other smart locks come with a key which can be used in situations where the battery in the lock has run flat.

This Yale lock does not come with a key. When the batteries run flat,  the lock can be powered by connecting a 9V battery to the two prongs at the bottom of the lock.

Software & Apps

[table id=127 /]

[expand title=”Read More” tag=”font color= green”]

This lock does not have apps that will turn your smartphone into a “electronic key” that will open your door.

However, if the lock is integrated into a home automation system, then those systems have apps that can be used to control this lock.

I explain more about this in the next section.

However, some of its functions can be controlled via a web browser, as part of a home automation system.

Home Automation

[table id=131 /]

[expand title=”Read More” tag=”font color= green”]

This Yale smart lock can be linked to other smart devices as part of a wireless home automation system. A smart device is one that is connected to the Internet and can be controlled remotely.

Essentially these devices can be controlled without you touching them- whether you are in another room or the other side of the world.

Apart from smart locks, there are lights, thermostats and fridges that can be linked and controlled remotely. Z Wave enables lots of different devices to be controlled via one piece of software.

The two home automation systems that the 240 can connect to are Z Wave and ZigBee. However, beware as there are two YRD 240 models- one of them uses Z Wave, the other uses Zigbee.

Just make sure that you buy the correct one.

One Tool

This lock just requires you to have a Phillips head screwdriver to install it.

There is no hard wiring to do and on most existing doors there are no new holes to drill and so, no in most cases the lock can be installed in less 30 minutes.

Existing Deadbolt

If this lock is replacing an existing lock then the lock and the deadbolt need to be taken out before your new Yale lock is installed.

Voice Prompted Set Up

To make the process as easy as possible, once installed there is a “voice prompted set up process” to help you along. This is available in three languages; English, Spanish and French.


As well as the 9V battery back up system explained earlier, the lock is powered by 4 AA batteries that are supplied and will last up to 1 year (depending on how often the lock is used.)

An alarm will sound to let you know when the power in the batteries is getting low.
