Understand Your Smart Lock

It is important to note that each smart lock is different. Each brand makes their locks using similar but different manufacturing processes. Also they offer different features across different makes and models.

This means that each model may have a different approach to deal with the situation of the battery dying. Before buying a smart lock, or if you already have one installed, make sure to understand what options you have available if the battery dies before being replaced.

Some models will be easier to deal with than others. Talk with an experienced security expert about the latest technologies that will suit your needs and budget.

Traditional Key Will Save The Day

The most common way to get a smart lock open when the battery has completely died is by using a traditional key.

Not only could the battery die, but there could also be another malfunction of the lock, or you may have forgotten the access code, etc.

How to Avoid Running Into The Issue of Dead Batteries

The best way to avoid running into having your smart lock battery die is to change the batteries often. Read the user manual for the specific model of smart lock that you own for the suggested times to change the battery. Then set reminders in your calendar at these intervals to let you know you should change them.

Alternatively you can use the low warning reminder that many smart locks provide. These may be a flashing light, audible noise or both. Get familiar with your device and change the battery when these warnings are seen. As a last resort make sure to understand how you can gain access to your smart lock if the batteries die. This will usually be with a traditional key so you should carry a copy with you always, just in case.
