The 2019 HR-V key fob uses a CR2032 3-volt lithium coin battery. This is the standard size for most Honda remotes, and a fresh battery typically restores full function at minimal cost.
In practical terms, the fob conceals a single coin cell inside a compact plastic shell. For U.S. market models, the CR2032 is the common replacement part. Replacing the battery is usually a straightforward DIY task that involves prying the two halves of the fob apart and seating a new coin cell correctly.
Battery model and where it fits
The CR2032 is a 3-volt lithium coin battery with a standard diameter of 20 mm and a thickness of about 3.2 mm. If you’re unsure which cell you need, check the old battery for the model, consult the owner's manual, or ask a Honda dealership to confirm the correct size for your specific fob.
How to replace the battery
To replace it, follow these steps. The following list explains the typical field procedure for the 2019 HR-V key fob.
- Use a small flathead screwdriver or a coin to gently pry apart the two halves of the fob along the seam.
- Carefully remove the old battery and note the orientation (positive side up).
- Insert a new CR2032 with the positive (+) side facing up, ensuring it sits flat.
- Rejoin the two halves, press until they click, and test the remote buttons to confirm operation.
Concluding: If the fob still has no function after a battery swap, the issue could be a dead fob circuit, antenna problem, or the need for reprogramming. A dealer or automotive locksmith can diagnose and reprogram a key fob if necessary.
What if the battery type is different in my region?
While CR2032 is the standard for most 2019 HR-V remotes, regional variations exist. Some markets may use a different coin cell such as CR2025. Check the existing battery or the owner's manual, or contact a local Honda dealer to confirm the exact model before purchase.
Where to buy and what to expect
CR2032 batteries are widely available at electronics stores, automotive shops, and online retailers. Plan to pay a modest price for a reliable battery; higher-quality brands may offer longer shelf life and better performance in colder conditions.
Summary
The 2019 Honda HR-V key fob takes a CR2032 3V lithium coin battery. Replacing it is a straightforward DIY task: identify the battery, open the fob, swap in a new CR2032 with the correct orientation, and reassemble. If performance doesn’t improve after replacement, seek professional help for programming or a potential replacement fob.
