Honda Accord Key Fob Remote Battery Replacement

My '03 Accord key fob was unresponsive and given the age of the remote (13+ years), it was very likely the battery being almost dead. Whenever buttons were pressed, either the response was sluggish or multiple presses were required. Changed the battery (uses CR1616 Li-ion) and sure enough, each button press worked on the first try! Super easy to do at the cost of a mass-produced battery and 5 mins of time.
