One day you realize that your key fob is not working as flexibly as before, and you think the cause is the battery drain. Let’s follow us to reach a step by step guide.
When Does The Key Fob Battery Need Replacing?
Shortened Signal Range
Normally, the key fob’s operating range of receiving signals is 20m. If you see this distance decreasing over time, your key fob has a problem. One common reason is that your battery is depleted or dead and needs to be replaced.
However, the rain sometimes affects the car remote’s ability to receive signals. On rainy days, if you have to approach the car to turn on the key fob, and the distance is still well maintained for the rest of the day, it is not a big problem.
In addition, a damaged remote transmitter or receiver also prevents the car box from catching the signal from the key. Chip failure or broken circuit in the remote battery makes it completely useless.
Common signs are headlights don’t flash or don’t even turn on, and there is no signal sound when pressing the button.
You own a weak battery if you have to press the key fob button panel too many times to unlock it. After a long time being used, the key fob will gradually run out of battery or have an internal battery failure. The battery installation area also has problems, such as a short circuit.
Cracks next to the installation area will hinder the battery from being correctly installed and cause a non-working Jeep key fob. It can shorten the battery’s life and cause it to drain more quickly.
Moreover, when you press the unlock button on the key fob too many times but the indicator light keeps blinking and then turns off, your battery is completely “exhausted”. It would be best if you asked someone else to bring you the backup key.
Receiving a slow signal is a common pointer of a key fob running out of battery. The key fob normally responds by turning on the car indicator light to inform you of the successful unlocking process.
However, if it responds slowly, about 5-10 seconds after you press it, the signal source it sends is too weak due to a drained battery.
This case is not always derived from a dead battery but can happen in case of faulty key fob programming. After replacing a coin battery, if your car remote does not respond as quickly as before, you should ask a car mechanic to reprogram the key.
