The most common battery used in Honda CR-V key fobs is the CR2032 lithium coin cell. This 3-volt battery powers most remotes reliably for several years.
There are exceptions. Some older or regional CR-V key fobs may use CR2025 or CR1616 cells, depending on the design. If you're unsure, check the battery itself or consult your owner’s manual or a Honda service center to confirm the correct type for your specific fob.
Common battery types for Honda CR-V key fobs
The following guide highlights the coin-cell varieties you might encounter in CR-V remotes. The CR2032 is by far the most common, but a smaller subset of fobs can use CR2025 or CR1616.
- CR2032 — standard 3-volt lithium coin cell used in the vast majority of CR-V key fobs.
- CR2025 — a thinner 3-volt cell used in some older or regional fob designs.
- CR1616 — a smaller coin cell used in a small subset of early Honda key fobs.
To be sure, examine the battery inside your fob for the exact size and markings. If the label indicates CR2032, CR2025, or CR1616, replace with that exact size and orientation.
How to identify the right battery for your fob
If you don’t have the owner’s manual handy, you can determine the correct battery by inspecting the current one and your vehicle’s year/trim information, as some fobs differ by generation.
Inspect the current battery and fob model
• Remove the back cover of the key fob with a small screwdriver or coin, taking care not to damage the case.
• Look at the markings on the battery itself to read the type (for example, CR2032).
• If the battery is missing or unclear, consult Honda’s online manuals by entering your year, model, and trim to confirm the correct size.
Replacing the battery in your key fob
Use the following steps to replace the battery in most Honda CR-V key fobs. The process is simple and can be done at home with a small flat-head screwdriver or a coin, depending on your fob design.
- Confirm the exact battery type by inspecting the current battery or your owner's manual.
- Gather a replacement battery of the same size (for example, CR2032) and ensure it is fresh (not expired).
- Use a small flat-head screwdriver or a coin to gently pry open the key fob case at the seam. Be careful not to damage the plastic tabs.
- Remove the old battery, noting the orientation (positive side up or down) as indicated by the fob’s contact layout.
- Insert the new battery with the correct polarity, aligning it with the metal contacts.
- Snap the two halves of the fob back together and test the remote by pressing a button to ensure it locks/unlocks and triggers the alarm.
After replacing, reassemble securely and avoid touching the battery terminals with bare fingers to prevent corrosion.
Care and caveats
Take care not to force the fob apart or bend the metal contacts. If the key fob still doesn’t work after a battery replacement, the issue may lie with the circuit board or the transmitter, in which case professional service is recommended.
Summary
In most Honda CR-V key fobs, the battery is a CR2032 lithium coin cell. Some older or regional remotes may use CR2025 or CR1616. Always verify by inspecting the battery itself or consulting the owner’s manual, and replace with the exact same size and orientation. With a fresh battery, your fob should function smoothly again, avoiding unnecessary trips to the dealership for simple power issues.

Fit and Functionality:
However, if it's too tight or prevents the case from closing properly, it might be better to stick with the CR2025 to avoid damaging the key fob. In summary, you can use a CR2032 instead of a CR2025 as long as it fits properly in the battery compartment of your car key.
