How to install a smart lock

Here are the most common steps to install a smart lock:

1. Check your door compatibility
2. Buy a smart door lock
3. Gather the tools
4. Replace the old lock with a smart lock
5. Set up power source
6. Connect smart lock to devices

 

1. Check your door compatibility

Before purchasing or installing a smart lock, confirm your door meets these basic requirements:

• Door thickness: Most smart locks work on doors between 1⅜ and 2 inches thick.
• Lock type: Your existing lock should be a standard single-cylinder deadbolt with a thumb turn on the inside and keyhole on the outside.
• Existing hardware: Check that your door has a clean strike plate and latch hole without damage or obstruction.

If your door doesn’t meet these requirements, you may need a professional installer or a different lock model. Checking compatibility now saves time and frustration later.

 

2. Buy a smart door lock.

When replacing an old lock, your first task is to purchase a new one. Therefore, before shopping, you should understand what kind of smart lock to look for, depending on the property type and tenant needs.

Things to consider when buying a new smart lock include:

• Connection type. Does the property require a WiFi-connected smart lock or a Bluetooth-powered lock? Will you need a WiFi bridge? Before you purchase a lock, you should be able to answer these questions confidently.
• Power source. Many smart locks require batteries, while others are hardwired. Each property type will have its needs, and some tenants may prefer one power source over another. Each type of smart lock power source has advantages and disadvantages, so it’s highly recommended that you do your due diligence before buying and installing.
• Brand. There are many types of smart lock brands on the market — and some are more well-known than others. Yet, the consensus is that most smart lock brands are somewhat affordable compared to other types of smart home security devices. Your responsibility is to research which brand fits the property’s needs best.
• Usability. Are you looking for a smart lock alerting you when the door is unlocked? Or do you want a door lock that enables you to unlock/lock the deadbolt while you’re away? Depending on your needs, there are hundreds of smart lock types available.

 

3. Gather the tools

Here is a list of the proper tools for a smart lock installation:

• Phillips-head screwdriver. This is the most essential tool for removing old hardware and securing new components.
• Tape measure. Measure your door thickness and the distance from the door edge to the center of the lock hole (backset) before purchasing a lock.
• Level. Ensures your new lock is installed straight and operates smoothly.
• Installation kit. Most smart locks come with specific screws, fasteners, and templates. Use the kit that comes with your lock.
• Manufacturer manual. Keep it nearby throughout installation. Referring to the manual saves time and helps you avoid mistakes.

Optional tools for some installations: power drill (if you need to adjust the latch hole), small file or sandpaper (for minor door adjustments).

 

4. Replace the old lock with a smart lock

The simplest step is to replace the old lock with the new one, which takes little time.

First, remove the screws supporting the lock on the door. Then, remove the knob and its components. However, you may come across a door knob without visible screws. In that case, you can follow the instructions below.

To remove a door lock without visible screws:

• First, look around the knob or handle for a small hole.
• When you find it, tilt the knob until you see a PIN appear.
• Then, insert the screwdriver until you feel the PIN click.
• Now, as you hold the screwdriver still, wiggle the handle until it comes off.
• Lastly, wedge the screwdriver between the metal cap and the door to leverage off the components.

Once you remove the old lock, replace it with the new smart lock using the specified instructions in the manual.

 

5. Set up power source

Now that the smart lock is installed according to its brand instructions, you can set up the power source.

If you’ve chosen to install a battery-powered smart door lock, you’ll insert the necessary batteries. On the other hand, if you’ve chosen a smart lock that runs on hardwired power, you’ll connect it to the building’s electrical system (which will require a more involved installation process).

 

6. Connect smart lock to devices

Now that the physical part of the smart door installation is complete, you can begin the setup process.

Here’s how to connect the smart lock to smartphone devices:

• Download the designated smartphone app and create an account.
• Select the smart device you want to connect.
• Connect the lock to your WiFi or Bluetooth.
• Create entry codes as prompted.

Smart lock installation troubleshooting

Here are some of the top smart lock installation troubleshooting issues:

• Connection issues
• Software issues
• Flashing light

 

Connection issues

Connection issues when installing your smart lock system are common and shouldn’t cause panic. Most of the time, a connection issue is due to WiFi connectivity malfunctions.

The simplest way to fix this issue is to try restarting the WiFi router and try again. Secondly, you can try turning your device off and then on again. This should reset the system and make it easier to connect.

 

Software issues

Sometimes, if a smart lock has been sitting in a warehouse or shelf for a while, the software might require an update in order to work properly. In that case, running a software update is an easy fix and shouldn’t take longer than twenty minutes.

 

Flashing light

The cause of a flashing light on a newly–installed smart lock can vary. However, the most common reason is a faulty battery or low-power alert.

To fix this issue, change the batteries (or buy a type of battery with better longevity) and turn it on again. Or, check the hardwiring as the connection to the power source might not be secure.
