Experiencing flickering headlights or dome lights that refuse to shut off even after you’ve parked and walked away from your 2016 Hyundai Elantra? This frustrating situation is more common than you might think and often points to a problem with your key fob or the car’s electrical system.
While a seemingly minor inconvenience, ignoring this issue can lead to a drained car battery, leaving you stranded and adding unnecessary stress to your day. Let’s dive into the possible reasons why your 2016 Hyundai Elantra lights won’t turn off with the key fob and explore some solutions.
Common Culprits Behind the Glowing Mystery
Several culprits could be the reason your Elantra’s lights refuse to turn off, ranging from simple user errors to more complex electrical issues. Here are the most common:
1. Faulty Key Fob Battery
Just like your Elantra needs a fully charged battery to start, your key fob relies on a small battery to communicate with your car. A dying key fob battery might struggle to send the signal to turn off the lights, causing them to stay on.
Expert Insight: “Always start with the simplest explanation first,” says automotive electronics specialist, James Park. “Replacing the key fob battery is a quick and easy fix that often resolves the issue.”
2. Malfunctioning Key Fob
Beyond a dead battery, the key fob itself can malfunction. Internal damage from wear and tear or even exposure to moisture can disrupt its communication with your Elantra, making it impossible to turn off the lights.
3. Stuck Ignition Switch
The ignition switch is responsible for sending power to various electrical components, including your lights. If the switch gets stuck, even slightly, it can prevent the lights from turning off completely, even when the key is removed.
4. Body Control Module (BCM) Issues
The BCM acts as your car’s brain for electrical functions like lights, locks, and wipers. A malfunctioning BCM can misinterpret signals, leading to issues like lights staying on.
5. Electrical Faults
Short circuits, damaged wiring, or faulty relays in your car’s electrical system can also cause the lights to stay on. These issues often require a professional diagnosis.
Troubleshooting Your 2016 Hyundai Elantra’s Lighting Dilemma
If you’re comfortable with basic car maintenance, here are a few things you can try before heading to a mechanic:
- Replace the Key Fob Battery: This is the easiest and often the most successful solution. Refer to your Elantra’s owner’s manual for instructions.
- Check the Key Fob: Examine the key fob for any physical damage or signs of moisture. If the fob appears damaged, replacing it is necessary.
- Jiggle the Ignition Switch: Try gently jiggling the ignition switch while the key is out to see if it releases a stuck position.
- Check the Fuses: Consult your owner’s manual to locate the fuse box and check the fuses related to your car’s lighting system.
Expert Insight: “While replacing fuses might seem straightforward, it’s crucial to use the correct amperage as a mismatch can damage your electrical system,” warns certified mechanic, Laura Chen.

If the issue persists after trying these solutions, it’s best to consult a qualified mechanic specializing in Hyundai vehicles. They have the expertise and tools to diagnose and repair complex electrical problems.
