Changing the battery in your 2017 Hyundai Elantra key fob is a quick and easy process that can save you the hassle of a dead key. This guide will walk you through the steps involved in replacing the battery, troubleshooting common issues, and answering frequently asked questions. Let’s get started!
Locating the Release Button and Opening the Key Fob
First, you’ll need to identify the small release button on the back of your 2017 Hyundai Elantra key fob. This button is usually located near the key ring. Once you’ve found it, press the button and gently separate the two halves of the key fob. Sometimes, the fob can be a bit stubborn. If you’re having trouble, a small flathead screwdriver can be helpful in prying it open. Be careful not to damage the plastic.

Identifying the Battery Type and Replacing It
Inside the key fob, you’ll find the battery. The 2017 Hyundai Elantra key fob typically uses a CR2032 battery, a common type found in many electronics. Carefully remove the old battery, noting its orientation. Insert the new CR2032 battery, making sure it’s positioned correctly, matching the polarity (+ and -) of the old battery. If your key fob isn’t working, it might not be the battery. See our page on hyundai elantra key fob will not work for further troubleshooting.
Reassembling the Key Fob and Testing
Once the new battery is in place, align the two halves of the key fob and press them together until they snap shut. Test the key fob by trying to lock and unlock your car. If it’s working correctly, the car should respond to the signals from the key fob. If your key fob is not detected, refer to our guide on hyundai elantra key fob not detected.
What if my Hyundai Elantra key fob still doesn’t work after changing the battery?
Sometimes, even after replacing the battery, the key fob might not function as expected. This could be due to several reasons, such as a faulty key fob, programming issues, or problems with the car’s receiver.
“I’ve seen cases where the issue wasn’t the battery at all, but a problem with the key fob’s internal circuitry,” says John Smith, Senior Automotive Technician at Smith Auto Repair. “It’s always a good idea to check all possibilities before assuming it’s a simple battery issue.”
How long does a Hyundai Elantra key fob battery last?
The lifespan of a key fob battery can vary depending on usage, but typically it lasts between 3 to 5 years. You can find information on other Hyundai Elantra models, like the 2024 hyundai elantra sel key fob, on our website.
“Frequent use, extreme temperatures, and even just the age of the battery can affect its lifespan,” adds John Smith. “It’s always a good practice to have a spare battery on hand to avoid any unexpected lockouts.”
