How do I replace the battery on the master key?
YourMechanic
Your Accord’s master key (the one with the built-in key fob and lock controls) needs a battery to operate. If you notice that it takes several presses of the button to get your doors to lock or unlock, it’s time to replace the battery.
Replacing the battery is easy. Here’s what you do:
Using a Phillips head screwdriver, unscrew the small screw on the back of the key.
Pry the two halves of the key apart.
Use a coin to pry the inner cover off.
Replace the old battery with a new one.
