The 2016 Honda HR-V key fob uses a CR2032 3-volt lithium coin battery. Replacing it is a common, do-it-yourself task that most owners can complete in a few minutes.
Battery type and specifications
The standard battery for the HR-V key fob is a CR2032, a 3-volt lithium coin cell. This size is widely used across Honda remotes from that era, with the typical dimensions being about 20 millimeters in diameter and 3.2 millimeters in thickness. Using the correct size is important to ensure proper contact and button response.
How to identify the correct battery
To confirm you have the right size, open the fob and check the battery label, or consult the owner's manual for the model year’s remote battery specification. The CR2032 is the most common choice for 2015–2016 HR-V key fobs, though regional variations can occur, so it’s wise to verify before purchasing a replacement.
Follow these steps to replace the battery safely:
- Remove the mechanical key blade from the fob by sliding the release and pulling it out.
- Use a small flathead screwdriver or a coin to gently pry apart the two halves of the fob along the seam.
- Locate and remove the old battery, noting which side is facing up. The CR2032 sits with the + side facing up in most cases.
- Insert a new CR2032 battery with the + side facing up, ensuring it sits flat and flush in the battery cavity.
- Reassemble the fob by snapping the halves back together and reinsert the mechanical key.
- Test the fob by pressing the buttons to confirm the remote functions (lock, unlock, trunk, etc.) are working properly.
With the battery replaced and the fob reassembled, the HR-V’s remote should respond normally. If the remote still fails to work after replacement, verify the battery orientation again and consider re-synchronization or consulting a Honda dealer for assistance.
Additional notes and tips
Proper handling helps prevent damage to the fob’s electronics. Avoid touching the battery contacts with your fingers, and store spare batteries in a cool, dry place. If your vehicle requires a re-synchronization after battery replacement, consult the owner's manual for the exact procedure or contact a Honda service center for guidance.
Summary
In short, the 2016 Honda HR-V key fob uses a CR2032 3V lithium coin battery. Replacing it is a straightforward, DIY process that involves opening the fob, swapping in a new CR2032 with the correct orientation, and reassembling. If problems persist after replacement, seek dealership assistance for re-sync or replacement options.
