Guide: How To Change Battery in Chevy z06 Key Fob

Asides from being one of the world’s prominent automobile manufacturers, Chevrolet is also known for its widely varied key fobs. You can find several keyless remotes for Chevrolet cars and it all runs down to the model of the car in question. Although these key fobs may look extremely different, they work in the same way.

Sooner or later, your Chevy key fob battery is going to drain up. At this point, you have no other option than to get it replaced. However, replacing the battery in a Chevy Key Fob might be extremely difficult especially when you do not know how to go about it. To make this easy, I will show you how you can easily change the battery in your Chevy Key Fob. 

Before we proceed into the steps, there are some things you will need to get ready for the replacement. They include;

  • A small flat-head screwdriver
  • A replacement battery


It is important that the screwdriver you will be using is small and has a flat head to make the process seamless. If not, you might experience so much difficulty going about such an easy task. Also, you should get a replacement battery ready so you don’t get the procedure delayed any longer.

Later in this article, I will show you the exact specification of the battery that you need to get for your Chevrolet Key Fob. Using a battery different in specification from the recommended one might put your keyless remote at risk. To avoid this, you should check which one has been recommended by the manufacturer. 

Remove the Physical Key

For most key fobs, the first step to battery replacement is the removal of the physical key. This is quite simple to do and does not require any technical action. However, you must be very careful while removing the physical key so you do not damage any internal part of the key Fob.

To remove the physical key, locate the button by the side of your key fob and push it down to release it. After pushing the button, you might have to apply a little force to pull the key out of the fob. However, you have to be very careful here so nothing gets damaged. After bringing the key out, proceed to the next step.


Open up the Remote

Before you can get access to the battery that has to be changed, you must first open up the remote itself. You might choose to open up the remote by inserting the key slightly into its position and forcing both ends apart or do it gently with the screwdriver you have set aside. You can go with whichever one suits you.

However, I’d advise you to use the screwdriver so you do not dent the physical key in the process. In case you are experiencing pullbacks with opening the remote, use the screwdriver to pry other ends of the fob, to equally distribute the pressure you are applying.

Remove the dead Battery from Chevy Fob

After opening the remote, you will find the battery compartment on one of both sides of the remote. For some manufacturers, you will find this on the chip part of the remote, and for others like Chevrolet, you’d find the battery compartment on a separate part of the remote. This makes the removal a whole lot easier. 

To remove the battery in your key fob, place the flathead screwdriver underneath it and gently raise it. In no time, the battery would be out and you can fix a new and healthy one. 

Replace the Battery

To replace the battery, simply follow the same step you have used to remove it, but this time, the other way around. While putting in the new battery, ensure the positive head is facing down for the circuit to be complete. The negative end facing down means your key fob will not work even after closing it.

Close the Remote 

After replacing the dead battery with a new and healthy one, you can go ahead to close the remote and start using your key fob again. Closing the remote is quite simple as you just need to fit it into the system as it was initially. You might want to be careful while doing this and ensure all ends are where they should be before proceeding.

There is no need to use the screwdriver or physical key when closing the remote. Using any of these might damage some parts of the plastic remote and render it useless. This means you will have to purchase a new part of the key fob or an entirely new key fob for your vehicle.

Insert the Physical Key

The final step is to insert the physical key back as it was in the key fob. Kindly ensure you insert it the exact way you removed it and do not force it in. If you feel some kind of restriction while putting it back in, you should simply remove it and insert it in the other direction.

Do I have to reset the Key Fob after changing the battery?

It is not necessary to reprogram the key fob after removing and replacing the battery. All you have to do is to start using the fob again as the programs will remain intact. However, if you are doing more than just changing the batteries of your key fob, then resetting the fob itself might be very important.

For example, you might choose to replace some of the internal wiring and electronics of your key fob. If such is the case, then you must reprogram it by pairing it with your vehicle once again. Not doing so means the key fob will not work for your vehicle any longer.

Final Words On Changing Battery from Chevy Key Fob

That isn’t prudent, and neither is it economic when all you have to do is replace the battery instead of getting a whole new key fob once again. So you don’t make the same mistake, you should make it a priority to replace the battery of your key fob whenever it goes down.
