The remote for most Honda Accord models uses a CR2032 3-volt lithium coin cell. Always verify by checking the back of your fob or your owner’s manual, as a few editions or regional variants may use alternative sizes such as CR2025.
Battery type by generation and how to verify
While CR2032 is the standard for most recent Accords, some older or regional remotes may differ. The best way to be sure is to inspect the existing battery or consult Honda's guidance for your exact model year.
Common battery types used in Honda Accord remotes
Here are the batteries you’re most likely to encounter in Accord remotes and when they tend to appear.
- CR2032 — The standard 3-volt coin cell used in the vast majority of current and recent Accord key fobs.
- CR2025 — A thinner variant used in some earlier models or regional variants where the fob’s interior is tightly packed.
- CR1616/CR1632 — Rarely used in modern Accords; if your fob is very old or from a non-US market, check the manual or read the battery marking.
Concluding: If you’re uncertain, ask a dealer or check the manual to confirm the correct type and orientation before purchase or replacement.
How to replace the battery safely
To replace the remote battery, follow these general steps. The exact method can vary by fob design, but the process below covers most Honda Accord remotes.
- Use a small flathead screwdriver or a coin to pry open the key fob carefully. Do not force the plastic or damage the circuit board.
- Take note of the battery orientation (which side is facing up) before removing the old cell.
- Insert the new battery (matching size, typically CR2032) with the correct polarity (+ side up as indicated on the inside of the fob).
- Reassemble the fob and press the buttons to test the remote from a short distance to ensure proper function.
If the fob still doesn’t work after replacement, verify that you used the correct battery size and orientation, or seek professional help to avoid damaging the fob.
Where to buy and tips
CR2032 coins are widely available at auto parts stores, big-box retailers, pharmacies, and online. Always use a fresh battery from a reputable brand for best performance and avoid mixing old and new cells.
Summary
The typical battery for a Honda Accord remote is a CR2032 3-volt coin cell. While CR2032 is standard for most current models, some older or specialized remotes may use CR2025 or other sizes. Verify by inspecting the existing battery or consulting the owner’s manual, and follow proper steps to replace it safely. If in doubt, contact a dealership or service center for assistance.
