If you’ve just found yourself locked out of your car with a dead key fob, we may be able to get you going. Remote key fobs are great until they fail. When they do, you may not be able to enter the car, and you should remove the battery out of Honda key fob immediately after that and replace the battery with the new one. If you do not have time for that, we’ve got loads of solutions here, so find the one that most closely fits your scenario.

These are the most likely solutions:

Swap the Battery

If your remote key fob has given up the ghost in the parking lot of a shopping center, you may be in luck. The battery may have failed, and getting it to work again might be as easy as replacing it.

To access the battery, you’ll have to open the fob. Typically, you have to use a coin or a small screwdriver to pry the battery cover open. The battery will look like a silver button. Look for the numbers on the battery and match those to a replacement battery.

Unlock the Door Remotely

Many manufacturers have remote door unlock services that can get you inside the car if your key fob is disabled, or if you’ve locked your keys inside. If your car doesn’t have an advanced remote unlocking system, roadside assistance can still get you inside. All of these services require that you have set them up ahead of time, and generally require a PIN.

How to Get Battery Out of Honda Key Fob

Trying to figure out how to get battery out of Honda key fob? Don’t panic! It’s really very simple and should only take you only a few minutes, but before we start, we need to mention some info about the battery life.

Honda mentions that average battery life for the key fob is ~3 years (pg 168 of Owners Manual), and that the key fob consumes battery if the remote is placed near strong radio waves. To preserve battery, Honda advises to avoid placing the fob near electrical appliances like televisions and computers.

Choosing the Right Honda Key Fob Battery

Most Honda key fobs use a flat circular 3-volt battery, which can usually be found at any hardware store in your neighborhood. You can also stop by the Honda of Toms River Parts Department, and we’ll make sure that you get the right battery for your Honda key.

Honda Key Battery Replacement

  1. Press and slide the button that releases the metal key, then slide the key out.
  2. Use the key or a small flathead screwdriver to pry the key fob open.
  3. Press your thumb down right above the battery to hold the fob together so the contents and external buttons don’t fall out.
  4. Remove the dead battery, taking note of the positive and negative sides, in order to install the new battery correctly. Don’t touch the terminals on the new battery. The oils on your skin can cause corrosion, which shortens battery life.
  5. Insert the new battery in the same position as the old one. Use the positive (+) and negative (-) marks inside the key fob as a guide.
  6. Align the two halves of the key fob and gently apply pressure until they snap back together.

Note: If your Honda key fob has a screw that holds the two halves together instead of a button, use a small flathead screwdriver to remove the screw, and then follow the steps above to replace the battery.
