Did you know that the key fob for your Cadillac is essentially a small computer with a big role? It’s one of the primary ways you interact with your vehicle, so it needs to be secure.

Your key fob has an embedded microchip to keep your car secure. It stores all kinds of personal information about you and your car, including an ID code that’s stored in a microchip inside the key fob. Because of this, changing the battery in your key fob isn’t as easy as changing the battery in some other remote controls you might own.

How To Change Battery in Cadillac Key Fob


Before you change the battery, let’s make sure that you really need to change the battery. The battery inside your key fob will eventually die and become completely unusable.

However, your key fob’s microchip stores all your car’s information. If you try to change the battery before it’s completely dead, you could lose your key fob’s information.

In some cases, you might also need to replace your key fob’s battery with a brand-new one if it’s been damaged. The battery might have been punctured, or it could be completely dead.

If the battery is damaged, you might not be able to properly install it in your key fob. You’ll want to replace the damaged battery with a new one before you replace the old one.


What You’ll Need


To change the battery in your Cadillac key fob, you’ll need a few basic tools. A small Phillips screwdriver, a small pair of needle-nose pliers, and a small flathead screwdriver should be enough to get the job done.

You’ll also need a small container to hold the old battery and a new battery for your key fob. Select an alkaline battery, because it’s more powerful than a standard zinc-based battery and is less likely to arc.

You can find a standard battery at any auto parts store and in many grocery stores. If the battery is punctured, you can also use a piece of electrical tape to cover the hole. You’ll want to keep the battery in a safe place while you’re working on your key fob, so don’t throw it in your pocket!


Step 1: Find the Battery Compartment


Before you can change the battery in your key fob, you need to find the battery compartment. The battery compartment may be underneath your key fob’s faceplate or hidden on the back of the device.

You may need to use a small screwdriver to pry the casing open or squeeze the tabs to pop it off. Be careful not to break the casing while you’re opening it. Once you’ve found the battery compartment, you can change the battery quickly.


Step 2: Disassemble the key fob


Use your pliers to gently pry the faceplate off the key fob. You might need to pry hard to remove the faceplate, so go slowly and apply even pressure.

When you’ve pried the faceplate off, you’ll have access to the battery compartment. You’ll also see a small circuit board inside the key fob. You’ll need to remove the battery from the circuit board before you can change the battery.

Gently pry the circuit board loose from the rest of the key fob. Be careful not to break any of the connections on the circuit board. If you feel the need to, wear a pair of rubber gloves to keep the oils from your hands off the circuit board.


Step 3: Install the new battery


Once you’ve pried the battery loose, you can remove the old battery. The battery will be in the same place in every key fob, but it might be under a piece of plastic.

If it is, gently pry the plastic away from the battery and remove it. Replace the plastic once you’ve installed the new battery. Use the pliers to gently fold the battery leads back over themselves and tuck them into the circuit board. Insert the battery back into its proper place.


Step 4: Test and Resync


Before you reinstall the faceplate, test your key fob to make sure it works properly. Press and hold the button on your key fob, and make sure that your lights blink as normal.

Once you’re sure your key fob works well, you can replace the faceplate. If you have a keyless entry system for your car, you may need to resync your key fob to your car. If you don’t know how to do this, contact your nearest Cadillac dealership to find out.
