The 2017 Chevy Malibu is a popular sedan known for its sleek design, reliability, and advanced technology features. However, like any vehicle, it is not without its quirks. One common issue that many owners encounter is a key fob that suddenly stops working. If you’ve found yourself locked out of your Malibu or struggling to use the remote functions, you’re not alone. In this article, we will explore the reasons why your 2017 Chevy Malibu key fob might not be working and offer effective solutions to get you back on the road.
Understanding Key Fob Functionality
To troubleshoot your key fob issues, it’s important to first understand how it works. The key fob is a small remote device that communicates with your vehicle’s main computer system via radio frequency. Most models, including the 2017 Chevy Malibu, come equipped with several functions, including:
- Remote Lock/Unlock
- Trunk Release
- Remote Start
- Panic Button
Each function is triggered by pressing buttons on the fob, which emits a signal that the car recognizes. If your key fob is not functioning properly, it can lead to a number of inconveniences, from being unable to unlock your doors to not being able to start your engine.
Common Reasons for a Non-Functional Key Fob
There are several reasons why a key fob may stop working. Identifying the root cause is crucial for effective solutions. Here are some of the most common issues faced by 2017 Chevy Malibu owners:
1. Dead Battery
One of the most frequent reasons for a malfunctioning key fob is a dead battery. Most key fobs use a small CR2032 or similar battery that can lose charge over time.
Signs of a dead battery:
– Inconsistent operation or delays in response
– Fob controls only working intermittently
– Warning lights on the dashboard indicating a key fob issue
How to Replace the Key Fob Battery
If you suspect that your key fob battery is dead, replacing it is a straightforward process:
- Open the Key Fob: Use a small flathead screwdriver to gently pry open the fob at the designated notch.
- Remove the Old Battery: Take out the old battery, paying attention to its orientation.
- Insert the New Battery: Place the new battery in the same orientation as the old one.
- Close the Key Fob: Snap the fob back together until you hear a click.
After replacing the battery, test your key fob to see if it is functioning normally.
2. Signal Interference
Sometimes, external factors can interfere with the radio signals sent between the key fob and the vehicle. This may include environmental elements or nearby frequencies from other devices.
Common sources of signal interference include:
– Other electronic devices (smartphones, laptops)
– Metal objects (keys in your pocket)
– Proximity to other vehicles
How to Minimize Interference
- Distance: Step away from electronic devices when using the key fob.
- Check Environment: Make sure you’re not in a crowded parking lot where numerous electronic devices are in close proximity.
- Location: Try using the fob in an open area to test if the range improves.
3. Faulty Key Fob
Like any electronic device, key fobs can fail due to internal malfunctions. This can be due to several reasons, including wear and tear or manufacturing defects.
Indications of a faulty key fob include:
– The fob doesn’t respond at all when buttons are pressed.
– Visible physical damage, such as cracks or broken buttons.
What to Do if Your Key Fob is Faulty?
-
Reprogramming: Sometimes, the key fob may require reprogramming to communicate with your vehicle again. This can usually be done at a dealership.
-
Replacement: If the key fob is confirmed to be faulty and cannot be reprogrammed, you may need to purchase a new key fob.
Solutions for Key Fob Issues
After identifying the problem, implementing the appropriate solution can save you time and energy. Here’s a summary of potential fixes:

What are the common reasons why a 2017 Chevy Malibu key fob may stop working?
The most common reason a key fob may stop working is due to a dead or weak battery. Key fobs rely on batteries to send signals to the vehicle, and over time, these batteries can lose their charge. If you notice that your key fob’s range has diminished, or if it requires multiple presses to function, it’s likely time to replace the battery.
Another frequent issue could be interference from other electronic devices. Key fobs operate on specific radio frequencies, and if there are other devices emitting signals at that frequency, it could disrupt communication between the fob and the car. Additionally, physical damage to the key fob itself could lead to malfunctioning, so check for any visible signs of wear and tear.
How do I replace the battery in my 2017 Chevy Malibu key fob?
To replace the battery in your key fob, start by locating the small notch or indentation on the side of the fob. Use a flathead screwdriver or a similar tool to gently pry apart the two halves of the fob. Be careful not to use excessive force, as this could damage the internal components. Once opened, you’ll find the battery compartment containing the battery.
Remove the old battery, ensuring you take note of the orientation—usually marked by a “+” symbol. Insert a new battery of the same type (typically CR2032 for many Chevy fobs) in the correct orientation and snap the key fob back together. After reassembling, test the fob to confirm that it’s working correctly.
What should I do if my key fob still doesn’t work after replacing the battery?
If your key fob is still not working after replacing the battery, it’s advisable to check for any physical damage to the fob or its components. Look for cracks, corrosion, or any signs that the buttons may not be functioning. Sometimes, internal circuitry can be damaged, which would require professional assistance to diagnose and repair.
Another possibility is that the key fob needs to be reprogrammed to sync with your vehicle. This can often occur after the battery has been replaced or if the fob is not functioning properly. Many dealerships or automotive professionals can reprogram your key fob, so consider consulting them for assistance if needed.
Can I use a spare key fob for my 2017 Chevy Malibu?
Yes, if you have a spare key fob for your 2017 Chevy Malibu, you can use it without any issues. Just ensure that the spare fob is properly programmed for your vehicle. If it hasn’t been programmed yet or if you’re not sure, you can easily get it programmed at a dealership or automotive locksmith.
In the case that you don’t have a spare key fob, you could consider purchasing a new one. Just know that new key fobs will also require programming. This usually involves connecting to your vehicle’s onboard computer, which can often be done by a professional technician or at the dealership.
Why does my key fob work intermittently?
Intermittent functionality of a key fob can be caused by a variety of factors, but one of the primary reasons is a weak battery. If the key fob’s battery is beginning to fail, it might work at times and fail at others, particularly depending on the ambient temperature or how far away you are from the vehicle. Checking and replacing the battery is the first step to resolving this issue.
Another consideration is the possibility of signal interference or proximity-related issues. If you are near other wireless devices or metal objects, they might impede the signal being transmitted by your fob. Make sure to eliminate such interference and test the fob again to see if its performance improves.
Can water damage affect my key fob’s functionality?
Yes, water damage can severely impact your key fob’s performance. Key fobs usually have a protection level against moisture, but if they are submerged in water or exposed to significant moisture, internal components can corrode or short out. If you suspect your fob has been exposed to water, drying it off immediately is crucial, but permanent damage may have already occurred.
If your key fob is not responding after getting wet, you can try removing the battery, letting the components dry out completely, and then reassembling it. However, if it still doesn’t work afterward, you may need to consider purchasing a replacement or seeking professional repair.
What are the costs associated with replacing or programming a key fob for my Chevy Malibu?
The cost of replacing or programming a key fob can vary widely depending on factors such as your location and where you choose to get the service done. Typically, purchasing a new key fob from a dealership can range from $50 to $300, depending on the model and technology features. If you opt for aftermarket options, you might find cheaper alternatives, but ensure they are compatible with your vehicle.
In addition to the cost of the fob itself, you might have to pay a fee for programming services. Dealerships often charge between $50 to $100 for this service, while automotive locksmiths may offer more competitive pricing. It’s recommended to call ahead for quotes and to confirm that they can program the specific key fob model for your 2017 Chevy Malibu.
