Honda Key Fob Low Battery Warning Message

The Honda key fob low battery warning message lets you know when your key fob battery needs to be changed and replaced, so you can continue using the remote.

Key fobs have made life much easier for drivers. Short for “finger operated button”, key fobs allow us to unlock all of the doors at once without having to fiddle with the keys.

Some cars are so sophisticated that they can be unlocked just by carrying the key fob with you as you approach the car. Unfortunately, the fobs use batteries which eventually run out of power. If your key fob battery went completely dead, you wouldn’t be able to start the car and could end up stranded somewhere. To prevent this from happening, there is a warning light on the dashboard that indicates when the battery should be replaced in the fob.

When the key is in use, the computer monitors the output voltage of the fob’s battery. Once the voltage gets to a certain point, the warning light will illuminate on the dash to let you know to replace the batteries.

Most fobs can be pried open to access the battery so you may not have to take your car anywhere. Your owner’s manual may have information on what type of battery should be used and how to replace it. Otherwise you can find this information online. Make sure that you use the correct type of battery. A different battery will have a different voltage and the system may not register properly, even if the fob still works.

If you have multiple key fobs, it’s a good idea to replace all of the batteries at the same time as they tend to run out at the same time. Keep in mind, some vehicles may require a reset procedure before the low battery key fob light will turn off.

Is it safe to drive with the key fob battery low warning light on?

This light doesn’t affect drive ability so it is okay to use the car normally if the light is illuminated. If you let the battery get too low on voltage, you may not be able to start the car. Don’t ignore the light and change the batteries out to prevent this from happening to you. If your key fob doesn’t appear to be working normally, our certified technicians can help you diagnose any issues.

You have weeks to replace the battery from the time you get the dashboard warning. The warning light comes on when the car senses either of the fob’s batteries as “low”.

So if you replace one key fob’s battery and the other key fob’s battery is low/dead and in range, it will turn the dash warning light on. Replace the batteries in both key fobs if you want the warning light on your dashboard to go out. They will die at almost the same time.

Once it senses the battery is above the low threshold it turns the warning light out automatically. Should be almost immediately.
You will never be stuck or stranded by this battery. You can start your car without the battery!

You just turn the key fob over to the back, slide the little latch over to the side, and remove the metal key from the fob.
You use the metal key in the driver’s door to open the door.
Once inside the car, you use the fob part to start the car by literally using the fob to press the “START/STOP” button in.
There is a sensor in the “Start/Stop” button that will read the fob when they are very close/touching each other.

These information are in the owner’s manual, if you want to learn how to replace the battery in detail read our guide, here.
