Identifying Your Car Remote Battery Type
Before you begin, it’s crucial to identify the correct battery type for your car remote. Car remote batteries come in various sizes and chemistries, and using the wrong battery can damage your remote or prevent it from functioning properly. The most common types of car remote batteries are:
- CR2032: A widely used button cell battery, often found in smaller remotes.
- CR2025: Similar to the CR2032 but slightly smaller.
- CR1632: Another common button cell battery, slightly larger than the CR2032.
- AAA or AA: Some larger remotes use standard alkaline batteries.
To determine the correct battery type for your remote, you can:
- Consult your car owner’s manual. It will list the specific battery type recommended for your vehicle.
- Look for a small label on the back of your remote that indicates the battery type. This label may be printed on the battery compartment cover or directly on the remote casing.
- Remove the old battery and take it to a local auto parts store or electronics retailer. They can help you identify the correct replacement battery.
Tools and Materials Needed
To change your car remote battery, you’ll need the following tools and materials:
- A new battery of the correct type for your remote.
- A small flathead screwdriver or a coin.
- A clean, dry cloth or paper towel.
Steps to Change Your Car Remote Battery
Now that you have the necessary tools and materials, let’s get started. Follow these steps carefully to ensure a successful battery replacement:
1. Open the Battery Compartment
Locate the battery compartment on your car remote. It’s usually located on the back of the remote and secured by a small screw or a snap-on cover.

Once the battery compartment is open, carefully remove the old battery. It may be held in place by a small tab or spring. Gently lift the battery out of the compartment and set it aside.
3. Insert the New Battery
Take the new battery and align the positive (+) and negative (-) terminals with the corresponding markings in the battery compartment. Gently press the battery into place until it sits securely. Make sure the battery is properly seated and not tilted or loose.
4. Close the Battery Compartment
Once the new battery is inserted, close the battery compartment. Ensure that the compartment is securely closed and the cover is properly aligned. If there was a screw, tighten it securely.
5. Test the Remote
Before you put your remote away, test it to ensure that the new battery is working properly. Press the lock, unlock, and trunk release buttons to see if they respond as expected. If the remote doesn’t work, double-check that the battery is inserted correctly and that the terminals are clean and free of corrosion.
