Is your 2011 Hyundai Elantra key fob starting to act up? Finding yourself pressing the buttons multiple times to lock or unlock your doors? The problem is likely a low battery in your key fob. Don’t worry, replacing the battery is a straightforward task you can easily handle yourself. This guide will walk you through each step to get your key fob working like new again.
Before we dive into the battery replacement, let’s quickly touch on your Elantra’s alarm system, as mentioned in your owner’s manual. It’s useful to know when the alarm might activate. According to the manual, the alarm will sound if a door, trunk, or hood is opened without using the key fob transmitter or the ignition key while the system is armed. If your alarm does go off, using your key in the door or starting the ignition should disarm it.
Now, back to the key fob battery. When your transmitter battery weakens, you’ll notice it takes multiple button presses to lock or unlock your Hyundai Elantra. The red LED light on the fob might also become dim or not light up at all. It’s time for a battery replacement.
The battery you’ll need is a common CR2032 battery. These are widely available at drugstores, supermarkets, and online retailers. Here’s how to replace it:
-
Gather Your Tools: You’ll need a small flat blade screwdriver and a new CR2032 battery.
-
Open the Key Fob Casing: Locate the small notch on the side of your key fob. Carefully insert the flat blade screwdriver into this notch and gently twist. This will separate the two halves of the key fob casing.
-
Remove and Replace the Old Battery: Once the case is open, you’ll see the battery. Note the polarity (+ side facing down). Carefully remove the old battery. Install the new CR2032 battery, ensuring the + side is facing down, just like the old one.
-
Close the Key Fob Casing: Snap the two halves of the key fob casing back together until they are securely closed.
-
Test Your Key Fob: Press the lock and unlock buttons to ensure your key fob is now working correctly. The LED light should be bright, and your car doors should respond immediately.
Important Note: No Reprogramming Needed
Unlike some other car brands, you do not need to reprogram your key fob after a battery replacement for your 2011 Hyundai Elantra. Once you replace the battery, your key fob should work immediately.
Replacing the battery in your 2011 Hyundai Elantra key fob is a quick and easy fix that can save you time and the hassle of a malfunctioning remote. By following these simple steps, you can get your key fob back in top shape and ensure you can easily access and secure your vehicle.
