The 2016 Honda Accord key fob uses a CR2032 3-volt coin cell battery.
Battery type and compatibility
For the majority of 2016 Accord key fobs, the CR2032 coin cell is the standard replacement. This compact 3-volt battery is widely available at automotive shops, big-box retailers, and online. If your fob design seems different from the typical remote, check the owner's manual or contact a Honda dealer to confirm the exact size.
Identifying the correct battery
Inspect the existing battery in the fob’s back cover or refer to the manual to verify the size. The CR2032 is commonly printed on the old battery; using a different size such as CR2025 or CR1632 will not fit properly and can cause damage.
How to replace the battery
Follow these steps to replace the battery safely and effectively.
- Open the back cover of the key fob by prying along the seam with a small flat-head screwdriver or a coin.
- Carefully lift out the old battery, noting which side is facing up.
- Insert a new CR2032 battery with the + side facing up toward the contacts.
- Snap the back cover back on and press until it clicks, then test the fob’s buttons to confirm it’s working.
After replacing, test all functions (lock, unlock, trunk, panic) to ensure the new battery is delivering adequate power. If the fob still shows reduced range or unresponsiveness, double-check the battery orientation and contacts, and consider replacing the battery again or consulting a dealer.
Battery longevity and disposal
To maximize performance and minimize waste, follow these guidelines before discarding or recycling the old battery.
- Never mix old and new batteries in the same fob or device; replace with a single new CR2032 only.
- Store spare batteries in a cool, dry place away from direct sunlight and heat sources.
- Keep the fob and battery contacts clean and dry; wipe with a dry cloth if needed.
- Recycle or dispose of used CR2032 batteries at appropriate facilities or retailer battery drop-off points, following local regulations.
By following these practices, you ensure reliable fob operation and responsible battery disposal. If you ever suspect water or corrosion damage or if the fob continues to malfunction after replacement, seek professional assistance from a Honda service center.
Summary
In short, the 2016 Honda Accord key fob typically uses a CR2032 3-volt coin cell. Replacement is a straightforward DIY task: pry open the back, swap in a new CR2032 with the correct polarity, reassemble, and test. Always recycle the old battery and consult a dealer if problems persist. This simple maintenance helps keep your remote functioning reliably for daily use and easy access to the vehicle.
