The most common answer is a 3-volt lithium coin cell, with CR2032 being the typical choice, though the exact size can vary by make and model. Always verify by inspecting the fob or consulting the owner's manual to avoid using the wrong battery.
This article explains the range of sizes you might encounter in 2006-era key fobs, how to identify the exact battery for your specific vehicle, and practical steps for a safe replacement.
Common battery sizes found in 2006 key fobs
Car remotes from around 2006 used a few standard coin-cell sizes. The exact choice depends on the fob’s design and the vehicle brand. When replacing, rely on the size printed on the old battery or consult a parts lookup for your exact model.
- CR2032 — 20 mm diameter, 3.2 mm thick; the most widely used coin cell for 2000s-era remotes.
- CR2025 — 20 mm diameter, 2.5 mm thick; used in some compact or lower-power remotes.
- CR1616 — 16 mm diameter, 1.6 mm thick; found in smaller remotes or earlier designs.
- CR1632 — 16 mm diameter, 3.2 mm thick; used in some models where space is tight but a higher capacity is needed.
Conclusion: While CR2032 is by far the most common for 2006-era fobs, several other coin-cell sizes may appear depending on the vehicle. Verify the exact size before purchase to ensure proper fit and performance.
How to identify your exact battery for a 2006 fob
Because manufacturers varied in 2006, confirming the exact battery for your specific car is essential. The steps below help you determine the correct size quickly and safely.
- Open the fob carefully and remove the existing battery. Look for a size marking on the battery itself (for example, CR2032 or CR2025).
- If the old battery is unreadable, measure its diameter and thickness to distinguish between common sizes (e.g., 20 mm × 3.2 mm for CR2032, 20 mm × 2.5 mm for CR2025).
- Consult the owner's manual or the manufacturer's official parts catalog for your year/model; many retailers list the exact battery type for specific fobs.
- If you’re unsure, take the fob to a dealership or a locksmith with your vehicle details to confirm the correct battery size and avoid compatibility issues.
Conclusion: Knowing the exact battery type prevents returns or fitting issues and ensures your fob works reliably after replacement.
Summary
In 2006, key fobs generally used 3V lithium coin cells, with CR2032 being the most common, though CR2025, CR1616, and CR1632 also appear depending on the vehicle. Always verify by checking the existing battery, consulting the owner’s manual, or using an official parts lookup to ensure you purchase the correct size and avoid damage or non-functionality.
Can I use a CR2032 instead of a CR2025 in a key fob?
Fit and Functionality:
However, if it's too tight or prevents the case from closing properly, it might be better to stick with the CR2025 to avoid damaging the key fob. In summary, you can use a CR2032 instead of a CR2025 as long as it fits properly in the battery compartment of your car key.
