What kind of battery does a Honda CR‑V key fob take?

Most Honda CR‑V key fobs use a CR2032 3V lithium coin cell. Some older CR‑V remotes (especially integrated key/flip-key styles from earlier model years) may use a CR1616 or CR1620 instead, so it’s best to check your specific fob or owner’s manual before buying. Below is a concise guide to identifying the right cell, replacing it safely, and avoiding common pitfalls.

How to identify the correct battery for your CR‑V key fob

The exact coin-cell type depends on the fob design and model year. You can often tell by the style of your fob and, if needed, confirm by opening the case or consulting the manual.

• Smart Entry/push-button start fob (2015–present on most trims): Typically uses a CR2032 3V coin cell.
• Integrated key with built-in buttons (common on 2007–2014 era): Often uses a CR1616 or CR1620 coin cell.
• Older separate rectangular remote (early 2000s era): May use CR1616 or CR1620; verify by checking the inside of the case or manual.

To be certain, check the owner’s manual, look for the battery code stamped inside the fob once opened, or match by the FCC ID/part number through a parts catalog. If in doubt, a dealership parts desk can confirm by VIN.

What you need to replace the battery

Swapping the coin cell is a quick DIY task. Gather the following tools and parts before you begin.

• New 3V coin cell (CR2032 for most recent CR‑V fobs; otherwise the exact type your fob specifies)
• Small Phillips screwdriver (some fobs have a tiny screw)
• Plastic pry tool or a coin (to open the case without marring it)
• Clean gloves or tissue (to avoid skin oils on the battery contacts)

Using a plastic tool helps prevent damage to the case and avoids shorting the contacts. Handle the new battery by the edges only.

Step-by-step replacement

These steps apply to most Honda CR‑V fobs, with minor variations depending on design.

1. Remove the mechanical key: Slide the release switch and pull out the metal key blade (if your fob has one).
2. Open the fob case: Insert a plastic pry tool or coin into the seam (often near the key slot) and gently twist to separate the halves. If there’s a tiny screw, remove it first.
3. Note the battery orientation: Observe the “+” side before removing the old cell. Carefully lift the battery out.
4. Install the new cell: Insert the replacement with the correct polarity (usually “+” facing up) and ensure it sits flat under all retaining clips.
5. Reassemble and test: Snap the case back together, reinstall the key blade, then test Lock/Unlock and, if applicable, start the vehicle with the fob in the cabin.

Reprogramming is not required after a battery swap. If the fob doesn’t work, recheck polarity, reseat the cell, and verify you installed the correct type.

Common signs your fob battery is low

Watch for these symptoms to avoid getting locked out or losing push-button start functionality at an inconvenient time.

• Reduced range or intermittent response when locking/unlocking
• Dashboard/key icon warnings or “Keyless remote battery low” messages (newer models)
• Needing multiple presses or holding the fob closer to the start button
• LED on the fob dim or not lighting when buttons are pressed

Replace the coin cell at the first sign of trouble to restore normal operation and prevent complete failure.

Where to buy and typical cost

You can source quality coin cells easily, but stick with reputable brands to avoid short life or leakage.

• Dealership/service center: Typically $5–$10 per cell; some dealers will install it for you.
• Retailers (hardware, electronics, auto parts): About $2–$5 each; multi-packs offer better per-cell pricing.
• Online: Competitive prices; buy from trusted sellers to avoid counterfeit batteries.

Choose name brands like Panasonic, Sony, Energizer, or Duracell. Verify the date code or “best by” to ensure fresh stock.

Safety and disposal

Coin cells are small but require careful handling and proper disposal.

• Keep new and used coin cells away from children and pets; ingestion is dangerous.
• Tape the terminals of spent cells and recycle them at electronics or hardware stores; don’t toss in household trash.
• Avoid shorting the battery with metal tools; handle by the edges to prevent corrosion from skin oils.

Responsible handling protects both people and the environment.

Model-year notes (general guidance)

While the CR‑V’s fob battery has standardized in recent years, older designs vary. Use this as a rough guide and verify for your vehicle.

• 2015–2025 CR‑V with Smart Entry/push-button start: CR2032 (most trims)
• 2012–2014 (mix of fob styles by trim): Often CR2032 for smart fobs; some integrated-key remotes may use CR1616/CR1620
• 2007–2011 integrated key remotes: Commonly CR1616 or CR1620

Because trims and regional specs differ, always confirm with the owner’s manual or the marking inside your specific fob.

Summary

In most cases, a Honda CR‑V key fob uses a CR2032 3V coin cell; older integrated-key remotes may require a CR1616 or CR1620. Confirm the exact type via the manual or the label inside the fob, then replace it using a simple DIY process—no reprogramming needed. Choose a reputable brand, handle carefully, and recycle the old battery responsibly.
