The battery type varies depending on the model year of your Odyssey. Common types include CR2032, CR2025, or CR1620. Identifying the correct battery type is crucial for a successful replacement.

  • Battery Compartment: A small compartment that houses the key fob’s battery.

Identifying the Battery Type

The battery type is typically printed on the battery itself or inside the battery compartment. If you’re unsure, consult your owner’s manual or search online for the specific battery type compatible with your Honda Odyssey model year.

Carefully close the battery compartment and snap it shut. Make sure it is securely closed and the latch mechanism is engaged. You may want to use a small piece of tape to temporarily secure the battery compartment cover to prevent it from accidentally opening.

Step 5: Test the Key Fob

Before putting the key fob away, test its functionality. Press the buttons to ensure they are working correctly. Try locking and unlocking the doors, opening the trunk (if equipped), and starting the engine. If everything functions as expected, you have successfully replaced the battery.
