Experiencing trouble with your Chevy Malibu key fob can be frustrating. Suddenly finding yourself locked out or unable to start your car due to a malfunctioning key fob disrupts your day. If you’re facing this issue, especially with a “Key Fob Not Working Chevy Malibu”, you’re in the right place. This guide will walk you through troubleshooting steps and provide a programming procedure to potentially resolve the problem yourself.
Common Reasons Why Your Chevy Malibu Key Fob Might Fail
Before diving into reprogramming, it’s helpful to understand why your key fob might stop working. Here are a few common culprits:
- Dead Battery: This is the most frequent cause. Key fob batteries, like any battery, have a limited lifespan and will eventually need replacement.
- Battery Contact Issues: Sometimes, even with a new battery, the contacts inside the key fob might be dirty or bent, preventing proper connection.
- Key Fob Damage: Dropping your key fob or exposing it to moisture can damage the internal components.
- Signal Interference: Strong radio frequencies can sometimes interfere with the key fob signal, although this is less common.
- Receiver Issues in the Vehicle: In rare cases, the problem might not be with the key fob itself but with the receiver in your Chevy Malibu that detects the key fob signal.
- Programming Loss: Occasionally, the key fob may lose its programming, especially if the car battery has been disconnected or drained for a prolonged period.
Troubleshooting Your Non-Working Key Fob
Let’s begin with some simple troubleshooting steps to identify and potentially fix the issue:
-
Battery Check and Replacement:
- Even if you’ve already replaced the battery, double-check that you used the correct type (usually a CR2032 battery).
- Ensure the battery is installed with the correct polarity (+ and – sides facing the right direction).
- Clean the battery contacts inside the key fob with a cotton swab and a bit of rubbing alcohol to remove any dirt or corrosion.
-
Check the Spare Key Fob: If you have a spare key fob, test if it works. If the spare works, this indicates the issue is likely with the original key fob and not the car’s receiver.
-
Proximity Test: Move closer to your Chevy Malibu and try using the key fob buttons again. If it works when you’re very close, but not from a distance, it could indicate a weak battery signal or potential interference.
-
Visual Inspection of the Key Fob: Carefully inspect the key fob for any signs of physical damage, such as cracks, dents, or broken buttons.
Reprogramming Your Chevy Malibu Key Fob When You Don’t Have Two Working Fobs
If troubleshooting steps don’t resolve the issue, and you suspect the key fob may need reprogramming, you can attempt the following procedure. Important Note: This procedure is for situations where you don’t have two already working key fobs. If you have two working fobs, the programming procedure is typically simpler and can be found in your owner’s manual.
This procedure is based on the information found in the 2021 Chevy Malibu owner’s manual and may be applicable to similar model years. Always refer to your specific owner’s manual for the most accurate instructions.
Steps to Reprogram Your Key Fob:
-
Prepare for Programming:
- Ensure your Chevy Malibu is turned off completely.
- Gather all the key fobs you want to program (up to eight can be programmed).
- Locate the transmitter pocket inside the center console storage area.
- Remove the key lock cylinder cap on the driver’s door handle to access the key lock cylinder.
-
Initiate Programming Mode:
- Insert the vehicle key from the key fob into the key lock cylinder on the driver’s door.
- Turn the key counterclockwise five times within 10 seconds.
- The Driver Information Center (DIC) will display “REMOTE LEARN PENDING, PLEASE WAIT”.
-
Wait and Repeat:
- Wait for 10 minutes. The DIC will change to “PRESS ENGINE START BUTTON TO LEARN”.
- Press the ENGINE START/STOP button.
- The DIC will again display “REMOTE LEARN PENDING, PLEASE WAIT”.
- Repeat the waiting and button-pressing process two more times (for a total of three cycles of waiting 10 minutes and pressing the button). After the third time, previously programmed key fobs will no longer work.
-
Program the New Key Fob:
- The DIC should now display “READY FOR REMOTE # 1”.
- Place the new key fob into the transmitter pocket in the center console, with the buttons facing towards the rear of the vehicle.
- Press the ENGINE START/STOP button.
- When the key fob is successfully programmed, the DIC will indicate it’s ready for the next key fob.
-
Program Additional Key Fobs (If Necessary):
- Remove the programmed key fob from the transmitter pocket.
- Press any button on the key fob (lock or unlock).
- To program more key fobs, repeat steps 4-6.
-
Exit Programming Mode:
- Once you have programmed all desired key fobs, press and hold the ENGINE START/STOP button for 12 seconds to exit programming mode.
-
Final Steps:
- Return the key back into the key fob if it was removed.
- Replace the key lock cylinder cap on the driver’s door handle.
- Test all programmed key fobs to ensure they are working correctly.
