'ZDNet Recommends': What exactly does it mean?

ZDNet's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.

When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNet nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.

ZDNet's editorial team writes on behalf of you, our reader. Our goal is to deliver the most accurate information and the most knowledgeable advice possible in order to help you make smarter buying decisions on tech gear and a wide array of products and services. Our editors thoroughly review and fact-check every article to ensure that our content meets the highest standards.

How to unlock the Yale Assure Lock SL when the batteries die

This feature is brilliant.

Written by Maria Diaz, Staff Writer on

Most things around us light up, beep, talk, sing, have a touchscreen or do all of the above. Everything seems to be plugged in or has batteries, even something as simple as the deadbolt on your door. But the world turns and batteries die, so what do you do when your keyless smart lock runs out of batteries? 

Many smart locks also have key access in case you do get locked out or simply prefer using your key, but keyless entry is becoming more popular. A keyless smart lock like the Yale Assure Lock SL doesn't have the option of using a key, making it lock-pick proof and more secure than the average deadbolt. But what are your options if your battery dies?

Before you pitch a tent in your front yard, get yourself a standard 9-volt battery -- available from any nearby convenience store -- and get ready to unlock your door as if you had magic powers.

Step 1: Get a fresh 9-volt battery

Step 2: Locate the two terminals under your Yale Lock's touchscreen

Step 3: Hold the 9-volt battery up to the terminals underneath your lock

Step 4: Wait for the screen to turn on as soon as the battery is against the lock

Step 5: Replace the batteries on the lock so this doesn't happen again

Your lock will let you know when your batteries are about to die, so pay attention to the health of your device. You can promptly replace the batteries while the lock is still powered, and you won't have to run out to the store to get a 9-volt battery in the future.
