The 2019 Honda Accord key fob typically uses a CR2032 3-volt lithium coin battery.
The exact battery is standard for most Honda remote keys, though there can be slight variations if you have a different fob model or a dealer replacement. Below, we explain what to expect and how to replace it.
Battery type and compatibility
Common fob configurations
For the 2019 Accord, the standard remote key fob relies on a CR2032 coin cell. This 3-volt lithium battery is widely used across many vehicle remotes and is readily available at electronics stores and supermarkets. If you’re unsure which version you have, check the back cover for a battery type code or consult your owner's manual.
Replacement steps
When the remote’s battery dies, you can replace it yourself with a few simple steps. Here is a practical, step-by-step guide.
- Remove the mechanical key: Press the release button on the back of the fob and pull out the metal key blade.
- Open the fob: Use a small flat-head screwdriver or a coin to gently pry apart the two halves of the fob at the seam.
- Take out the old battery: Note the battery orientation before removing it.
- Insert the new battery: Place a CR2032 with the "+" side facing up, ensuring it sits flat and aligned with the contacts.
- Reassemble the fob: Snap the two halves back together and reinsert the mechanical key.
- Test the fob: Press buttons to confirm the remote unlocks, and use the mechanical key to start manually if needed.
Disposal and extra tips: Dispose of the old battery properly at a battery recycling center. If the fob still doesn’t work after replacement, the issue may be the internal circuit or antenna, and you may need to visit a dealer or locksmith.
Notes on variations
Honda occasionally updates key fob designs, so if you’ve recently replaced or purchased an aftermarket fob, verify the battery type. Some older or aftermarket components may use different coin cells, such as CR2025, but CR2032 remains the standard for most 2019 Accord remotes.
Summary
In short, the usual battery for a 2019 Honda Accord key fob is a CR2032 3V lithium coin cell. Replacing it is a straightforward DIY task using the steps above, and proper disposal is recommended.
