The 2016 Chevy Malibu is a sleek and modern vehicle, equipped with various high-tech features, including a key fob that adds convenience to your driving experience. However, like any other electronic device, key fobs can encounter issues. If you’re facing a situation where your key fob isn’t working, don’t worry! This comprehensive guide will provide insights into the potential causes and solutions for your 2016 Chevy Malibu key fob problems.
Understanding Your Key Fob
Before diving into the troubleshooting steps, let’s first understand how your key fob operates.
What is a Key Fob?
A key fob is a small, remote device that often contains buttons for locking and unlocking your vehicle, opening the trunk, and sometimes even starting the engine. The 2016 Chevy Malibu’s key fob operates via radio frequency and communicates wirelessly with the car’s Electronic Control Unit (ECU).
Common Features of the 2016 Chevy Malibu Key Fob
Some key features of the 2016 Chevy Malibu key fob include:
- Remote locking and unlocking of doors
- Remote trunk release
- Engine start functionality
Understanding these features can help you determine which functions are not operational if your key fob is malfunctioning.
Why Isn’t Your Key Fob Working?
There can be several reasons why your 2016 Chevy Malibu key fob is not functioning as intended. Let’s explore the common issues that may lead to key fob failure.
1. Dead Battery
One of the most common reasons for a malfunctioning key fob is a dead battery. Like any battery-operated device, the longevity of your key fob’s battery can vary depending on usage.
Signs of a Dead Battery
If your key fob’s functions have become erratic or completely stopped working, the battery is likely drained. Here are a few symptoms of a dead battery:
- Range issues: The key fob works only when you are very close to the car.
- Intermittent functionality: The key fob works sometimes but not consistently.
2. Damaged or Faulty Key Fob
If the battery isn’t the issue, the key fob itself may be damaged or malfunctioning. This could result from physical trauma, exposure to moisture, or general wear over time.
How to Identify Damage
Signs of a damaged key fob may include:
- Cracked casing or damaged buttons
- Water damage or corrosion
- Non-responsive buttons
3. Issues with the Vehicle’s Receiver Unit
The problem may also lie with the receiver unit in your Chevy Malibu. The key fob communicates with a receiver within the vehicle, and if there are issues with this receiver—either a malfunction or a blown fuse—the key fob may not work properly.
Identifying Receiver Unit Issues
Look for signs that your vehicle’s system may not be functioning properly:
- Other electronic features in the vehicle malfunctioning
- Warning lights on the dashboard regarding keyless entry problems
4. Reprogramming Required
Sometimes, the key fob may simply need reprogramming due to various reasons, including battery disconnection or software updates in your vehicle.
Signs You Need to Reprogram
If your key fob is not responding and previously worked correctly, reprogramming may be necessary. Look out for the following:
- The key fob operates only intermittently.
- The key fob does not unlock or lock the doors despite having a new battery.
Troubleshooting Steps for a Non-Working Key Fob
If you’re experiencing issues with your 2016 Chevy Malibu key fob, consider following these troubleshooting steps to determine the root cause.
Step 1: Check the Battery
The first step in troubleshooting should always be to inspect the battery. Here’s how to do it:
How to Change the Battery
- Press the release button on the key fob to separate the two halves.
- Remove the old battery. Take care not to damage the battery compartment.
- Insert a new CR2032 battery with the positive side facing up.
- Reassemble the key fob and test its functionality.
Step 2: Inspect for Physical Damage
Check your key fob for any signs of damage. If you notice any cracks, dents, or water exposure, it might be time to replace the key fob.
Step 3: Verify Vehicle Systems
Next, check your vehicle’s electronic systems. Ensure that other electronic features are functioning to rule out battery or fuse issues in the car.
Steps to Check the System
- Turn the ignition on and check for dashboard warnings.
- Test the car’s interior lights and other functionalities.
Step 4: Reprogram the Key Fob
If you’ve changed the battery and checked for damage or system issues, reprogramming the key fob might work. Here’s how:
- Insert the key into the ignition and turn to ‘On’ without starting the engine.
- Press and hold the lock and unlock buttons simultaneously for about 15 seconds.
- Remove the key from the ignition and test the fob’s features.

What should I do if my 2016 Chevy Malibu key fob is not working?
If your key fob isn’t functioning, the first step is to check the battery. Key fobs typically use a small coin-cell battery that can deplete over time. You can usually find the owner’s manual for your Chevy Malibu online or in the glove box to determine the exact battery type. Replacing the battery is often a simple process that can restore the fob’s functionality.
If replacing the battery doesn’t resolve the issue, try reprogramming the key fob. You can find instructions for reprogramming your key fob in the vehicle’s owner manual or by searching online. In some cases, you may need to visit a dealership or a qualified locksmith for assistance, especially if the fob has experienced physical damage.
Could there be an issue with the vehicle’s receiver?
Yes, it’s possible that the problem lies with the vehicle’s receiver rather than the key fob itself. The key fob communicates wirelessly with the car, and if the receiver is malfunctioning or damaged, it might not pick up the signal from the fob. This is a less common issue, but it can occur due to electrical problems or exposure to water.
If you suspect a problem with the vehicle’s receiver, it’s advisable to have a professional diagnostic test performed. A qualified technician can examine both the key fob and the vehicle’s electronic systems to identify any underlying issues. They can provide you with an accurate assessment and recommend appropriate repairs.
How often should I replace the battery in my key fob?
Typically, it’s recommended to replace your key fob battery every 1 to 3 years, depending on usage. Frequent usage can lead to faster battery depletion, so if you find yourself using the key fob regularly, you may need to replace it more often. Keeping an eye on performance can help you catch battery issues before they prevent the key fob from working.
It’s helpful to replace the battery proactively if you notice a decrease in range or if the buttons seem unresponsive. Always opt for a high-quality battery from a reliable brand to ensure optimal performance. If you’re unsure about replacing the battery yourself, most auto parts stores can assist you with installation.
What if my key fob is physically damaged?
If your key fob has physical damage, such as cracks or broken buttons, it may be the reason it’s not functioning correctly. Physical damage can disrupt the electrical circuits inside the fob, preventing it from sending signals to the vehicle. In some cases, you may be able to repair minor damage, such as replacing a button, but extensive damage often necessitates a new key fob.
If replacement is necessary, you have a couple of options. You can purchase a new key fob from a dealership or order one online. Keep in mind that even if you get a new key fob, it often requires programming to work with your vehicle. Consult your dealership or an automotive locksmith for the necessary programming services.
Can I use my spare key fob while the primary one is malfunctioning?
Yes, if you have a spare key fob, you can certainly use it while troubleshooting or repairing your primary fob. This is a great temporary solution that allows you to continue using your vehicle without significant interruption. If the spare key fob works without issues, it reinforces the likelihood that the problem lies solely with the malfunctioning fob.
Should you discover that both key fobs are not functioning, further investigation may be necessary. This may involve checking for issues within the vehicle itself, such as receiver problems or even blown fuses. If everything seems functional and the issue persists, it’s wise to consult a professional for a detailed diagnosis.
Why does my key fob have a limited range?
If your key fob has a limited range, there can be several reasons for this. One common cause is a low battery, which can reduce the signal strength and therefore, the range at which you can operate the fob. If you notice that your key fob works only when you are very close to your vehicle, replacing the battery should be your first step.
Another potential factor could be interference from electronic devices. Radio waves and signals from surrounding electronics can interfere with the key fob’s communication with the vehicle. Additionally, physical barriers like walls or structures can also impact range. If replacing the battery doesn’t resolve the issue, consider potential sources of interference or consult with a professional for further troubleshooting.
Is there a way to troubleshoot my key fob without professional help?
Yes, you can perform some basic troubleshooting steps on your own to identify the issue with your key fob. Start by checking the battery, as a simple battery replacement can resolve many problems. Ensure that the battery is installed correctly, paying attention to the positive and negative orientation. If the fob has been exposed to moisture or extreme conditions, it may require drying out before functioning again.
You can also attempt to reset or reprogram your key fob to see if it resolves the issue. In most cases, the owner’s manual provides instructions on how to do this. If the problem persists after following these steps, it may indicate a more serious issue, warranting professional assistance. Remember that while DIY troubleshooting can help, certain problems will require expert evaluation and repair.
