Identifying the Battery Type
Before you begin, it’s crucial to identify the type of battery your car remote uses. Most car remotes use either a CR2032 or a CR2016 battery, but some may use other sizes. To determine the correct battery type, you can:
- Consult your car’s owner’s manual. It will typically list the battery type and size required for your remote.
- Examine the battery compartment of your remote. The battery type is often printed on the battery itself or on the compartment’s interior.
- Take your remote to a local auto parts store. They can usually identify the battery type based on the remote’s appearance.
Tools You’ll Need
Replacing a car remote battery is a straightforward task that requires only a few basic tools:
- A small flathead screwdriver or a prying tool (optional)
- The correct replacement battery (CR2032 or CR2016, depending on your remote)
Step-by-Step Battery Replacement Guide
Now that you’ve identified the battery type and gathered your tools, let’s proceed with the battery replacement process:
1. Open the Battery Compartment
Locate the small compartment on your car remote where the battery is housed. It’s usually on the back of the remote and secured with a small screw or a sliding panel. Use your screwdriver or prying tool to carefully pry open the compartment. If there’s a screw, unscrew it gently.
2. Remove the Old Battery
Once the compartment is open, you’ll see the old battery. Gently remove it from its holder. Be careful not to touch the metal contacts on the battery, as this can damage it. (See Also: Are Most Car Batteries 12 Volt? The Truth Revealed)

Take the new battery and align its positive (+) and negative (-) terminals with the corresponding contacts in the battery holder. Insert the battery firmly into its place. Make sure it’s seated correctly and securely.
4. Close the Battery Compartment
Carefully close the battery compartment and secure it with the screw or sliding panel. Ensure it’s tightly closed to prevent water or dust from entering the compartment.
5. Test Your Remote
With the new battery installed, test your remote by pressing the buttons. The lights should illuminate, and the remote should respond as expected. If it doesn’t work, double-check that the battery is inserted correctly and that the contacts are clean.
Important Tips and Precautions
Here are some additional tips and precautions to keep in mind when replacing your car remote battery:
- Dispose of the old battery properly. Most auto parts stores accept used batteries for recycling.
- Avoid using a rechargeable battery in your car remote, as it may not provide the necessary voltage or lifespan.
