Make sure the battery’s positive (+) mark is facing up when you install it.

6. Replace the two parts of the key fob cover and press with your hands until it closes completely.

7. Finally, re-enter the key fob key that you previously removed.

If you accidentally drop that part of the key fob when you remove the battery of your old Honda key fob, then some pieces will come off.

But don’t worry because you can easily reassemble the parts. The order of installation from top to bottom is:

  • Lock button
  • Unlock button
  • Trunk button
  • horn button

After that, attach the button holder with the longer side facing down and the curved side facing the button.

Then, you can install the rubber cover and install it snugly and easily.

Do This After You Replace Your Key Fob Battery

After successfully replacing the battery in your key fob for your Honda, you will need to check it to help ensure that it is still functioning correctly.

So, if your Honda doesn’t respond to the instructions from the remote, try opening your key fob again. Double-check, is the battery pointing in the right direction?

Mostly don’t put your fingers anywhere near the circuits of your key fob when you aren’t experienced in working with electrical equipment.

The pushbutton on a vehicle key will eventually wear down as time goes on, which is inevitable.

When you press the button, the interactions transmit signals to the circuit boards so they may follow the instructions.

The key fob buttons will eventually wear out, leaving a space between them and the contacts.

Frequently pushing the buttons on your fob is among the quickest processes to tell whether the key fob buttons are still functioning or not.

Examine the following scenarios to see if one of them relates:

  1. Some buttons, or even all, can only be activated by pressing them in a particular sequence.
  2. Only one of the buttons is active, while the others are not.

If somehow the material (plastic) that protected your key fob is broken off, you likely have an issue with your vehicle remote.

You can try to open your key fob with simple equipment and inspect it for damage on contacts or buttons that aren’t oriented correctly.

But, when it doesn’t succeed, you will need to change your key fob.

Following replacing the battery in your vehicle remote, there is a chance that it will no longer operate because of the lock issue.

Examine the vehicle regarding any of such symptoms to determine whether or not the locks or doors have problems.

Several things, such as moisture and fractures, can harm your key fob.

The key fob may be broken if it stops operating after you accidentally dropped it in liquids or when you try to open it.

You can check using a spare key or check whether the keyfob button can be pressed or not.

The remote will likely reset when you replace the key fob battery.

If you push particular icons on your key fob, it is also possible to reset it.

Therefore, the inability of the key fob to function correctly is also a clear indication that your key fob has been reset.
