The 2017 Honda CR-V key fob uses a CR2032 3-volt lithium coin battery.
In this article, we explain the exact battery type you need, how to replace it, and practical tips to keep the fob working reliably.
Battery type and model you’ll need
The standard remote for the 2017 CR-V relies on a common CR2032 coin cell. This 3-volt lithium battery is widely available at electronics stores, supermarkets, and auto parts retailers. If you’re unsure, check the inside of the fob or the owner’s manual for the exact specification; most 2017 CR-V remotes use CR2032.
What a CR2032 is
A CR2032 is a flat, round coin cell about 20 mm in diameter and 3.2 mm thick. It’s one of the most common sizes for car remotes and other devices.
How to replace the battery
Replacing the battery is straightforward. Follow these steps to avoid damaging the fob:
- Use a small flat-head screwdriver or a coin to gently pry apart the two halves of the key fob.
- Remove the old battery from its contact—note the orientation (positive side up).
- Insert a new CR2032 with the positive (+) side facing up, ensuring it sits flat and fully contacts the terminals.
- Snap the fob halves back together and test the remote functions to confirm it works.
If your fob uses a different size battery, do not force-fit it. The CR2032 is the correct choice for most 2017 CR-V remotes.
Where to buy and what to expect
CR2032 batteries are widely available. Here are common places to shop and typical considerations:
- Electronics and hardware stores often stock CR2032 batteries in single or multi-packs.
- Drugstores and supermarkets carry coin batteries, typically in the electronics or battery aisle.
- Automotive parts stores and dealerships can provide the battery and minor service, though at a higher price.
- Online retailers offer packs of CR2032 with fast shipping, which can be cost-effective for multiple replacements.
When buying, verify that the label says "CR2032" and "3V." Avoid counterfeit or expired batteries; check the package for expiry dates and batch information.
Care, handling, and battery life tips
To maximize life and reliability, keep the fob out of extreme heat, moisture, and direct sunlight. Replace the battery about every 1 to 3 years depending on usage, and consider replacing both the battery and the gasket seal if your fob begins to feel loose or loses range.
Summary
The 2017 Honda CR-V key fob uses a CR2032 3-volt lithium coin battery. Replacing it is a simple DIY task: pry open the fob, swap in a fresh CR2032 with the correct orientation, and reassemble. These batteries are affordable and widely available from multiple retailers, and proper handling can extend the fob’s life.
