The 2012 Honda CR-V key fob typically uses a CR2032, a 3-volt lithium coin cell.
The question concerns the exact battery size for the factory remote in a 2012 CR-V and how to replace it correctly. While CR2032 is standard for most CR-V remotes from that era, some fobs or replacement shells may use CR2025, so verify the size before purchasing and opening the fob.
Battery type and compatibility
Understanding which coin cell fits your CR-V remote helps prevent buying the wrong size and minimizes faqs about performance.
- Most 2012 Honda CR-V key fobs use a CR2032 3-volt lithium coin cell.
- Some remotes, especially aftermarket or certain shells, may use a CR2025; if yours is unusually slim or labeled differently, confirm the size before replacing.
- Always replace with a fresh, brand-new coin cell and ensure the correct orientation when reassembling the fob.
In short, CR2032 is the norm for the 2012 CR-V key fob, but double-check your specific remote if you’re unsure.
Replacement steps
To replace the battery, follow these steps carefully to avoid damaging the fob.
- Gather a small flat-head screwdriver or a coin, and obtain the correct replacement coin cell (CR2032 in most cases; CR2025 only if your fob requires it).
- Remove the physical key blade from the fob if present to allow easier access to the housing.
- Gently pry apart the two halves of the fob to expose the battery tray.
- Note the orientation of the old battery, then remove it from the tray.
- Insert the new battery with the correct polarity (positive side up) and reseat it firmly.
- Reassemble the fob and test the buttons to confirm proper operation.
If the remote still fails after replacement, the issue may lie with the electronics or programming, and you may need to reprogram the fob or consult a dealer or locksmith.
Additional notes
Some 2012 CR-V configurations may feature additional remote features or different housings, but the battery size for the standard key fob remains generally CR2032. If you’re unsure, consult the owner’s manual or inspect the existing battery for the size imprint before purchasing.
Summary
The 2012 Honda CR-V key fob most commonly uses a CR2032 3V lithium coin battery. Replacement is straightforward: open the fob, replace with the correct coin cell, and reassemble. If the remote doesn’t function after replacement, seek professional help to reprogram or diagnose the fob.
