The short answer is that it depends on the vehicle, but most 2013-era key fobs use a 3-volt coin-cell battery such as CR2032. Some models use CR2025 or CR2016, and a few rely on a small rectangular A23 (23A) battery. Always verify with your vehicle’s manual or by inspecting the fob.
In practice, the 2013 model year covered a wide range of remotes with different shapes and battery sizes. To ensure you replace with the correct part, identify your car’s make, model, and year, then confirm the battery code from the current battery or the manual.
Common battery types for 2013 key fobs
These are the coin-cell and small-format batteries most frequently used in 2013-era remotes. Exact choice depends on the manufacturer and fob design.
- CR2032 — 3V coin cell, very common in modern fobs
- CR2025 — 3V coin cell used in some slimmer or tighter-fitting fobs
- CR2016 — 3V coin cell used in smaller or older designs
- A23 (23A) — 12V rectangular battery used in a minority of remotes
Having the correct cell size is essential for proper button press responsiveness and range. If you’re unsure, don’t guess—check the manual or have a professional confirm the model-specific battery.
How to identify the exact battery for your vehicle
To confirm the exact battery, use these steps:
- Check the owner’s manual or the inside of the key fob’s back cover for a label with the battery type.
- If the cover is open, read the battery’s markings (e.g., CR2032, CR2025) or compare its size to standard batteries.
- Note your vehicle’s make, model, and year, then search online or contact the dealer with your VIN to verify the correct replacement.
- Purchase a fresh battery from an auto parts store or pharmacy, matching the exact type and size; avoid mixing sizes.
- Replace the battery in a clean, dry environment and test the fob’s function before closing the case.
By following these steps, you ensure the fob works reliably and avoid damage from using an incorrect battery type.
Tips and safety
Always dispose of old batteries properly at a recycling center. Avoid touching the contacts with metal jewelry and wash hands after handling. If the fob case is damaged, consider professional replacement rather than attempting a DIY fix.
Summary
For 2013 key fobs, the battery type varies by model, but CR2032 is the most common, with CR2025 and CR2016 also used in some designs. A small number of remotes use an A23 battery. To be certain, check the vehicle’s manual or inspect the current battery to match the exact size and voltage. When in doubt, consult a dealer or trusted auto parts retailer with your vehicle details.
