Most 2020 key fobs use a CR2032 coin-cell battery, though some models may use CR2025 or another size. Check your owner’s manual or inspect the fob to confirm the exact type.
Common battery types for 2020 key fobs
Key fobs from different manufacturers typically fall into a few size categories. The CR2032 coin cell is by far the most common for 2020 vehicles, with CR2025 appearing in some thinner or smaller remotes. Other sizes are rare but possible in select models. Always verify the exact specification for your vehicle.
- CR2032 – the most common coin-cell size for 2020 key fobs.
- CR2025 – used in some thinner or more compact fobs.
- Other small coin cells (such as CR1632/CR1616) – rare and usually found in older or non-standard fobs.
If you’re unsure, consult the owner’s manual or contact the dealership or manufacturer for the precise replacement part number before purchasing a battery.
How to identify the correct battery for your 2020 key fob
Use these steps to confirm the exact battery type and ensure you buy the right part. This process helps avoid misfits and ensures the fob functions properly after replacement.
- Open the key fob casing by gently prying along the seam with a small flat tool or coin, taking care not to damage the plastic.
- Look at the battery itself for a printed code (for example, "CR2032"). If readable, this is the exact type you need.
- If the code isn’t legible, measure the diameter and thickness: a CR2032 is 20 mm in diameter and 3.2 mm thick; a CR2025 is 20 mm by 2.5 mm.
- When in doubt, reference the vehicle’s owner’s manual or contact the dealer for the precise replacement part number.
Concluding: Using the correct battery size ensures proper fit, contact alignment, and remote functionality. An incorrect size can prevent the fob from working or damage contacts over time.
Summary
In most 2020 vehicles, the key fob battery is a CR2032 coin cell, with CR2025 as a common alternative for thinner remotes. Always verify the exact size by inspecting the fob, consulting the owner’s manual, or asking the dealership to confirm the correct replacement part before purchasing. This ensures reliable performance and avoids damage to the fob.
