Battery type and compatibility
For the 2017 Honda Fit, the standard remote keyless entry fob typically requires a CR2032 battery. This is a common 3-volt lithium coin cell that fits most Honda fobs of that era. If you recently replaced the battery and the fob still isn’t working, double-check the orientation and ensure the fob casing is fully closed.
To replace the battery, follow these steps:
- Remove the mechanical key blade by sliding the release and pulling it out.
- Gently pry apart the fob case to expose the internal battery.
- Take out the old battery and insert a new CR2032 with the positive (+) side facing up.
- Reassemble the fob and press the buttons to confirm proper operation.
After the replacement, your key fob should respond normally if the battery orientation is correct and the case is securely closed. CR2032 batteries are widely available and typically offer 2–5 years of life depending on usage.
What to do if the fob still doesn’t work
If the fob remains unresponsive after replacing the battery, consider reprogramming or re-synchronizing the fob with your vehicle, or having a dealership or automotive locksmith diagnose potential issues such as worn contacts, wear on the button pads, or electronic faults.
