The 2018 Honda HR-V key fob uses a CR2032 3-volt lithium coin cell.
The standard remote for the HR-V relies on a single CR2032 battery housed inside the fob. While this size covers most models, some regional or aftermarket variants can differ; if you’re unsure, inspect the current battery or consult the owner's manual. Replacing the battery is a quick, inexpensive task you can do at home.
Battery type and compatibility
Below are the key points to confirm the correct battery size for your 2018 HR-V key fob and how to identify it.
- Standard battery size: CR2032, a 3-volt lithium coin cell, is the most common choice for the 2018 HR-V key fob.
- Alternative sizes: In rare cases, some variants or regional models may use CR2025 or CR1632. If you’re unsure, inspect the current battery or consult the owner's manual to confirm.
- How to verify: Open the fob’s seam to reveal the battery; compare the dimensions to the CR2032 (20 mm diameter, 3.2 mm thick) to ensure a proper fit.
- Replacement approach: Use a small flat tool or coin to gently pry the cover apart; replace with a fresh CR2032 with the positive (+) side facing up; snap the cover back into place and test the fob.
