Most 2013-era key fobs rely on a 3-volt coin-cell battery, with CR2032 being the most common size. However, the exact type can vary by make and model, so it’s essential to verify the specific battery for your vehicle by checking the fob or the owner’s manual.
Battery sizes you might encounter
Common coin cell sizes
Below are the coin-cell sizes you’re most likely to encounter in 2013 key fobs. While CR2032 is by far the standard, CR2025 and CR1616 appear in some models.
- CR2032 — 3V lithium coin cell; the most widely used size for many car brands from that era.
- CR2025 — 3V coin cell; found in a subset of models and trims.
- CR1616 — 3V coin cell; seen in a minority of smaller or older fobs.
Keep in mind that the exact size can vary by vehicle. Using the wrong battery size can prevent the fob from working properly, so it’s worth double-checking before replacing.
How to confirm the exact battery for your vehicle
Steps to identify your battery type
To confirm the correct battery for a 2013 key fob, use a quick verification process that relies on the fob itself and official documentation.
- Inspect the fob’s back cover or inner casing for a battery size marking (e.g., CR2032) or pictograms indicating fitment.
- Open the fob carefully to view the current battery; note its size and model as you remove it so you can replace with the same type.
- Consult the vehicle’s owner's manual or the manufacturer's website for the specified fob battery type for your exact year, make, and model.
- When in doubt, visit a local automotive parts store or dealer with your vehicle information to confirm the correct battery size.
Using the correct battery not only ensures reliable operation but also helps prevent damage to the fob’s electronics or the keyless-entry system.

How to replace safely and efficiently
Here are practical steps to replace a 2013 key fob battery with minimal hassle.
- Work on a clean, flat surface and use a small notch or pry tool to avoid damaging the fob.
- Handle the new battery with clean hands or a non-metallic tool to prevent oils or fingerprints from affecting contact.
