How to Replace the Key Fob Battery in a Acura Integra

Steps from the 2026 Acura Integra owner's manual (Models without two-way keyless remote and models with two-way keyless remote (same steps)).

Remove the built-in key from the remote.
Pry on the edge of the cover with a flat-tip screwdriver to remove the cover.
Wrap the screwdriver with a cloth to prevent scratches.
Replace the battery, making sure the polarity is correct.

Battery type: CR2032.
Replace the battery if the indicator does not come on when the button is pressed.
Two-way keyless remote models also have a non-replaceable rechargeable battery; replace the CR2032 every three to four years.
