What size battery does a Honda key fob take?

A CR2032 measures 20mm across and 3.2mm thick, 3.0V. That size is what the fob holder is built for, so match the number printed on the old cell rather than a cell that merely fits.

How do I replace the battery in a Honda key fob?

Pry the fob open with a flat-head screwdriver at the seam (or use the built-in key slot), note the polarity, remove the old cell, insert a fresh CR2032 and snap the case shut.

How long does a Honda key fob battery last?

Typically 2–3 years of normal use. When the remote range drops, replace the cell.

Why is my Honda key fob not working after a battery change?

Confirm the new cell is the right size and voltage, that the polarity is correct and the contacts are clean. Reseat the cell if needed.
