Symptoms of Honda Civic key fob low battery

A key fob low battery on Honda Civic can be really frustrating, especially to unsuspecting car users who may not know. People who have never experienced this issue may panic and think it is an electronic problem. However, the following are some of the symptoms you will experience.

The weaker the fob battery becomes, the more the transmitter loses its range. As a result, there is a need to move near the car for the fob signal to reach. It will take some time before it dies completely; hence there’s time to replace.

Low Battery Warning Light

A low battery warning light is an easy sign to see. This is where the car system is able to identify the fob battery condition and relay the same to the dashboard display. For new Honda Civic models, a warning will appear on the dashboard.

It is crucial to note that this is not available for all Honda Civic models but just the new models. Check your car to know if it has this feature.

Over-clicking

Over-clicking happens when you find yourself clicking the buttons on your car key fob several times to make sure the doors are locked or unlocked. Normally, a single push on the button is enough to lock your doors. However, as the battery dies, the strength reduces, causing this effect even when near the door.

Inconsistent Performance

For people who do not understand enough about key fobs, they may not understand the cause of inconsistent performance. It comes from a low battery on the key fob. However, some people may not think so since it works well in some cases and fails in others.

If you are experiencing this problem, then there are high chances your car key fob battery is about to die.

Many people may not know this, but the key fob can reset when replacing the battery. Do not panic when this happens. It will make your Honda civic key fob fail to recognize your car. The best thing to do is to program your car key fob again.

Steps to Follow to Program Honda Civic Remote Control Unit

So you need to reset your car. These are steps to help you program your Honda remotes.

Step 1: Start by getting all the car remotes you have. However, only one remote will be required for the programming, although all remotes will be programmed. The process will delete the previous programming on all remotes.

Step 2: Get into the vehicle and ensure all doors are closed but unlocked. This process must be carried out from inside the car.

Step 3: Start by turning the key into the ON position, which is just one click from the ignition start. The lights on your accessories will come on as well as the dash lighting up.

Step 4: Count 5 seconds after you have turned on your key to the ON position. Then press the LOCK button on the remote control for a second.

Step 5: Turn the key back to the OFF position.

Step 6: Repeat steps 4 & 5 for additional two times to have a total of 3 ON/OFF cycles. However, make sure that each step happens within 5 seconds intervals from the previous one.

Step 7: This noise indicates your Honda is now in Remote Programming Mode. Do not turn the key off. For the fourth time, turn the key to the ON position, and on the remote, press the “LOCK” button. You will hear a clunk of noise on your car locks. However, the door will not have locked. The noise is an indication that the car has entered Remote Programming Mode.

Step 8: If you want, you can still program multiple remotes. To do this, press the LOCK button on the rest of the remotes for 1 second. For a period of 5 seconds, the step will be complete just like the previous ones. However, note that the Remote Programming mode will be active for just 10 seconds. For Honda, only a maximum of 3 remotes can be programmed.

After each of the three remotes is programmed and memory has been restored, the locks will make a clunking noise that resembles the noise made when locking doors.

Step 9: For the final step, just turn your key back to the OFF position, then remove it from the car ignition. You may now test all the keys to make sure they are programmed.

Can I drive my car with my key fob battery dead?
