If your 2014 Nissan Sentra key fob isn’t working, you’re not alone. This is a common problem for many Sentra owners, but luckily, it’s often an easy fix. There are several reasons why your key fob might be acting up, ranging from a dead battery to a faulty connection.
Common Reasons Your Key Fob Might Be Malfunctioning
Before heading to the dealership, here are a few things you can check at home to try and troubleshoot the issue:
1. Dead Key Fob Battery
The most common reason for a malfunctioning key fob is a dead battery. Over time, the battery inside your key fob will naturally drain, especially with frequent use.
Signs of a dead key fob battery:
- The car doesn’t respond to any button presses on the key fob.
- You need to be very close to the car for the key fob to work.
- The car’s alarm system doesn’t activate or deactivate.
How to fix it:
- Refer to your owner’s manual to find the type of battery your key fob uses. It’s usually a CR2025 or CR2032 3V lithium battery.
- Carefully open the key fob casing. You might need a small screwdriver or a coin, depending on your key fob’s design.
- Replace the old battery with a new one, ensuring the positive (+) and negative (-) sides are correctly aligned.
- Reassemble the key fob.

2. Key Fob Programming Issues
Sometimes, the key fob itself might be fine, but the issue lies in its programming. If the key fob is not properly programmed to your specific Nissan Sentra, it won’t be able to communicate with your car.
Signs of key fob programming issues:
- The key fob worked before, but suddenly stopped.
- You recently replaced the car battery or had electrical work done on your car.
How to fix it:
- You can try reprogramming the key fob yourself at home. Refer to your owner’s manual for specific instructions as the process can vary between car models.
- If you’re not comfortable reprogramming the key fob yourself, you can take it to a dealership or an automotive locksmith who can program it for you.
3. Faulty Key Fob or Internal Damage
If replacing the battery and reprogramming the key fob doesn’t work, there might be internal damage to the key fob itself.
Signs of a faulty key fob or internal damage:
- Some buttons on the key fob work, while others don’t.
- The key fob only works intermittently.
- You notice physical damage to the key fob, like cracks or water damage.
How to fix it:
- Inspect your key fob for any signs of physical damage.
- If there’s internal damage, you’ll likely need to replace the key fob.
- You can purchase a new key fob online, at a dealership, or from a qualified automotive locksmith.

- Weak car battery: In some cases, a weak car battery might not have enough power to respond to the key fob signals.
- Antenna issues: The antenna in your car receives signals from the key fob. If the antenna is damaged or faulty, it might not receive the signal properly.
- Interference: Other electronic devices operating on the same frequency can sometimes interfere with the signal between the key fob and the car.
When to Consult a Professional
If you’ve tried the troubleshooting steps above and your 2014 Nissan Sentra key fob is still not working, it’s best to consult a professional. A qualified automotive locksmith or your dealership can diagnose the problem accurately and recommend the best course of action.
