Chevy Malibu might be the one of the most loved cars that come out of GM, so many people love it. They love it since they are usually seen as reliable, sturdy and well-designed cars. The Chevy Malibu is a great car that people want to own.

Unfortunately, not everyone is lucky enough to have a new Chevy Malibu, so if you’re one of those who doesn’t, then you can still find a way to make your Chevy Malibu work as good as it should.

Key fob is one of the most important components in your car, and it’s your last line of defense when you need to unlock the doors. So when the key fob stops working, you need to fix it as soon as possible.

Today we will learn how to fix a Chevy Malibu key fob which has a not working issue.

Dead 12 Volt Battery

Both systems in the Malibu need the battery to be in a good condition to work.

If one of the battery’s terminals is completely discharged, or a temporary interruption to the power supply occurs due to corrosion, then the computer in your Malibu won’t function properly.

Consequently, you may need to open the car door with a manual key. Also, many of the car’s electric appliances (such as headlights, fans, and infotainment system) may not work properly or very badly, and the engine may not turn over.

Make sure the 12 volt battery is connected correctly.

Battery has a Poor Connection

The batteries in the ignition switches of your new Chevrolet Malibu have metal studs which keep them in place and make it possible to turn the car on and off.

If there is no tension in the plastic clips holding the battery in place, there can be contact issues and the remote may stop functioning.

Make certain that the batteries are securely installed and do not move about easily by shaking the remote. Also, check that all of the battery contacts are not corroded or covered in dust.

Receiver Part is Defective

Chevy Malibu cars have a receiver that can receive radio frequency signals sent to it by the key fob. If none of these receivers work, it is possible that the receiver has faulty components.

If all the remote keyless entry systems on the vehicle are not working and you are not able to program the remote keys, the receiver module in the system has a problem.

You will probably have an easy way to tell if the security module is faulty, but it is possible that the receiver module will not be able to receive any commands from the remote keyless system.

You will have trouble identifying the fault by performing a diagnostic scan. The security module can malfunction because it is unable to detect an antenna that is used to communicate with external devices.

In some cases, using a diagnostic scan to check that the commands sent to the security module are in fact received by the security module are actually sent to it and if so, what the security module does with the commands.
