Car key remote fobs are nice to have, but they all stop working eventually. Even if it’s just a dead battery, you can fix your dead Honda key fob battery. Also, you can pretty much guarantee that your car doors will fail to unlock with the remote at one time or another.
While there are a few reasons that a keyless entry remote might stop working, most of them are pretty easy to check yourself. The most common problem with these car key fobs is that the batteries go dead over time, in which case replacing the battery should fix the problem.
Fix Your Dead Honda Key Fob Battery
Key fobs get their fair share of physical abuse, and they aren’t indestructible. The two most common points of failure are the battery terminal contacts and the buttons, although there are many other ways they can break.
The best way to check this out on your own is to pull the remote apart again and do a thorough visual inspection. If the battery connector terminals are broken, you can tell by looking at them, and they may also feel loose. If they are, carefully soldering them back in place may return your broken key fob to useful service.
If the battery terminals don’t look broken, you may find an issue where the buttons are soldered and have come loose. They may be soldered back in place as well if you find that they have come loose unless a button physically snaps off. In that case, you’ll typically need to obtain a new remote.
The rubberized buttons used by most car key remotes can fail in many ways. If you notice that one or more of the buttons look like they aren’t popping back out correctly or seem to have come apart inside, that can prevent a car key remote from working properly.
In that case, try removing the buttons, cleaning them, flexing them in and out, and then reassembling the remote. If the buttons still don’t work, you’ll need to obtain a new remote.
How Do I Change the Battery in My Honda Civic Key?
When your Honda keyless remote battery is low, use the following steps to open the Honda key fob, remove/replace the battery, and finally, put the key fob back together. It’s everything you need to know when your Honda keyless remote battery is low:
- Press and slide the button that releases the metal key, and then slide the key out.
- Use the key or a small flathead screwdriver to pry the key fob open.
- Press your thumb down right above the battery to hold the fob together so the contents and external buttons don’t fall out.
- 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.
- 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.
- 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.
Reprogramming a Car Key Remote
For a car key remote to work securely, it has to be effectively paired with the receiver unit in your car. Then someone with the same make and model can’t walk up and use their fob to unlock your vehicle.
If your keyless entry remote and your car are no longer on speaking terms, you will have to reprogram your car’s keyless entry system to regain your car key remote functionality. You can accomplish this by turning the key in the ignition several times with the doors shut.
