The 2014 Honda Accord key fob uses a CR2032 3-volt lithium coin battery.
This widely used cell powers most Accord remotes from that era, and replacement is a routine DIY task. If you’re unsure, check the old battery inside the fob or refer to the owner's manual. Batteries of this type are inexpensive and readily available at auto parts stores, pharmacies, and online retailers. Regional variations are rare, but when in doubt, confirm the exact battery type for your market with a dealer or the manual.
Battery type and compatibility
The CR2032 is a compact, 3-volt lithium coin cell that fits the 2014 Accord key fob. Using the correct size ensures a secure fit and reliable operation. If you notice reduced range or intermittent responsiveness, a worn battery is a common cause and replacement typically restores full function.
Note on regional differences
In most markets, the CR2032 remains the standard battery for the 2014 Accord key fob. If you’re buying a replacement abroad or in a non-US market, verify the exact battery specification with the manual or a local dealer to avoid compatibility issues.
If you decide to replace the battery yourself, follow these steps:
- Gather a fresh CR2032 3-volt lithium coin cell and a small flathead screwdriver or a safe coin for prying open the fob.
- Flip the fob over and locate the seam where the back cover meets the main housing.
- Gently pry along the seam to pop off the back cover. Do not force the plastic or bend the case.
- Remove the old battery, noting the orientation (positive side typically faces up toward the circuit board).
- Insert the new CR2032 with the positive side facing the same direction as the previous battery, ensuring it sits flat on the terminals.
- Reattach the back cover, pressing around the edges until it snaps securely shut. Test the fob by locking/unlocking the doors from a short distance to confirm operation.
If the fob still doesn’t respond after replacement, the issue may lie with the car’s receiver or the fob’s programming. In most cases, no reprogramming is required after a battery swap, but some situations may require dealer or locksmith assistance to re-sync the key with the vehicle.
Summary
Bottom line: the 2014 Honda Accord key fob uses a CR2032 3V lithium coin battery. Replacing it is quick and affordable: pop off the back, swap in a fresh CR2032 with the correct orientation, reseal, and test. Keep a spare battery on hand and dispose of the old cell properly. If problems persist, consult a Honda dealer or qualified locksmith for further help.
