Common 2012 Chevy Malibu Key Fob Problems
Understanding the root cause of your key fob malfunction is the first step to finding a solution. Here are some common culprits:
1. Dead Key Fob Battery
This is the most frequent reason for key fob failure. A weak or dead battery can prevent the fob from sending signals to your car.
Symptoms:
- Key fob doesn’t work at all
- Key fob only works intermittently or at close range
Troubleshooting:
- Replace the battery: Most 2012 Chevy Malibu key fobs use a CR2032 battery. Refer to your owner’s manual for instructions on how to open the fob and replace the battery.
2. Key Fob Programming Issues
Sometimes, the connection between your key fob and your car’s computer can become disrupted. This might happen after a battery change or for seemingly no reason.
Symptoms:
- Key fob unlocks the doors but won’t start the engine
- Remote start doesn’t function
Troubleshooting:
- Reprogram the key fob: You can often reprogram the key fob yourself by following a specific sequence of button presses outlined in your owner’s manual. Some models may require a visit to a dealership or qualified locksmith.
3. Key Fob Receiver Malfunction
The receiver in your car is responsible for receiving the signals from your key fob. If it’s faulty, it won’t matter if your key fob is working perfectly.
Symptoms:
- None of the key fob buttons work
- The key fob only works very close to the car
Troubleshooting:
- Check the fuses: A blown fuse related to the keyless entry system can disable the receiver. Refer to your owner’s manual to locate the fuse box and identify the correct fuse.
- Inspect the receiver antenna: The antenna is typically located near the rearview mirror or in the headliner. Look for any damage or loose connections.
- Consult a professional: Diagnosing and repairing receiver issues usually requires specialized equipment and expertise, so it’s best to consult a qualified automotive electrician.
4. Physical Damage or Wear and Tear
Over time, your key fob can sustain damage from drops, water exposure, or simply wearing down.
Symptoms:
- Buttons stick or don’t respond
- Cracks or damage to the key fob casing
Troubleshooting:
- Repair or replace the key fob: If the damage is minor, you might be able to find replacement buttons or casings online. For extensive damage, you’ll likely need a new key fob.
