The 2016 Honda CR-V key fob runs on a standard 3-volt CR2032 coin-cell battery.
In practice, Honda remotes from this era typically use the CR2032 cell, though regional variations can exist. If you’re unsure, check the back of the old battery, the owner’s manual, or consult a dealer or auto parts store to confirm the exact size before purchasing.
Battery type and specs
Here are the common specifications you’ll encounter for the 2016 CR-V key fob battery. These details help ensure you buy the correct replacement and understand why it matters for performance.
- Battery type: CR2032
- Voltage: 3V
- Physical size: approximately 20 mm in diameter and 3.2 mm thick
- Availability: widely stocked at auto parts stores, supermarkets, and electronics retailers
- Disposal: recycle according to local guidelines for lithium coin cells
With the correct battery installed, the key fob should operate normally, unlocking doors and, in some models, starting the engine via a push-button system. If performance remains inconsistent, recheck the battery orientation and ensure the contacts are clean and undamaged.
Replacing the battery
If you need to replace the battery, prepare a clean workspace and the right replacement battery. The steps below outline a typical replacement process for a 2016 CR-V key fob.
- Inspect the fob and locate the seam where the two halves meet. If the fob has a mechanical key blade, slide it out as a precaution.
- Use a small flathead screwdriver or a coin to gently pry apart the two halves along the seam. Apply steady, even pressure to avoid damaging the plastic.
- Carefully separate the halves to reveal the battery compartment. Note the current battery’s orientation (which side is up).
- Remove the old battery and set it aside. Clean the contacts if necessary to ensure a good connection.
- Insert a new CR2032 battery with the plus (+) side facing up (toward the buttons). Snap the fob halves back together and test the buttons to confirm operation.
Note: If the fob still doesn’t respond after replacement, verify the battery is oriented correctly and that the new cell isn’t defective. If problems persist, a dealer or locksmith can reprogram or troubleshoot the remote.
Variant notes
Some markets offer a slightly different fob shape or a smart-key system. The underlying battery type remains the CR2032 in most cases, but if you have a nonstandard fob, consult the owner’s manual or a Honda service technician to confirm the correct replacement.
Summary
For a 2016 Honda CR-V key fob, the standard replacement battery is a CR2032 3V coin cell. Confirm the exact size by inspecting the existing battery or the owner’s manual if you’re unsure. Replacement involves opening the fob along the seam, swapping in a new CR2032 with the correct orientation, and resealing the housing. Always test the fob after replacement to ensure reliable operation.
