Understanding Your Key Fob
Before you begin, it’s crucial to understand the type of key fob you have. Key fobs vary significantly in design, from simple flip keys to sophisticated smart keys. Knowing your key fob type will help you determine the correct battery replacement procedure. Some fobs require specialized tools, while others can be opened with a simple coin or flathead screwdriver. Misidentifying your fob type can lead to damage, so careful examination is essential.
Identifying Your Key Fob Type
Most key fobs fall into one of these categories:
- Standard Flip Key: These have a key blade that folds into the fob body. The battery compartment is usually accessible by sliding a release button or using a small flathead screwdriver.
- Smart Key/Keyless Entry: These are often sleeker and may not have a visible key blade. They usually have a small release button or notch that allows you to access the emergency key and, subsequently, the battery compartment.
- Proximity Key/Push-Button Start: These fobs are typically larger and may have additional buttons for features like remote start. The battery compartment location varies depending on the make and model.
Gathering Your Tools
Once you’ve identified your key fob type, gather the necessary tools. Most key fobs require a small flathead screwdriver or a coin. You’ll also need the correct replacement battery. The owner’s manual for your vehicle will specify the battery type. Common types include CR2025, CR2032, and CR1632. Purchasing a high-quality battery ensures longer life and better performance.
Choosing the Right Battery
Using the wrong battery can damage your key fob. Always refer to your owner’s manual or search online using your car’s make, model, and year to confirm the correct battery type.

Now you’re ready to change the battery. Follow these general steps, adapting them as needed for your specific key fob:
