Signs Of A Dying Car Key Battery

The most common sign of a dying car key battery is when the key fails to unlock or lock the car doors. Another sign is when the key cannot start the car even if the battery is fully charged. You should also pay attention to the lights; if the key don’t turn them on, there might be an issue with the battery. In some cases, the key may even stop functioning altogether, leaving you stranded. Let’s split each sign more deeply:

Lower Signal Range

A common fob has a signal range of 30 to 60 feet. However, if your remote’s battery runs out of power, it will reduce the functional range of your fob.

Have you noticed that your fob now demands you to approach your car more closely than it did previously? Is it no longer sending the signal from the opposite side of the parking lot as it once did?

Your key fob battery is most likely to blame. Please be aware that weather conditions, such as rain, might affect your device’s signal strength.

If you find any issues with your car key fob and don’t know what to do, don’t hesitate to contact a Chandler mobile auto locksmith.

Inconsistent Clicks

You may have to press the button on your key fob repeatedly before your car receives the signal. When this happens, your battery struggles to gather enough power to function. If this is the case with your key fob, you need to get a new key fob battery quickly.

Some key fobs are merely used to open doors, while others are necessary to start push-to-start engines. Your key fob may be at fault if this component is likewise erratic and takes numerous pushes.

Delayed Unlocking

Although you may only need to click the button once, there is a considerable one or two-second wait before hearing your car unlock. This is another sign that the battery on your key fob is running low.

Some reports claim that when you unlock the car, the headlights may even stop blinking. It may appear harmless today, but you’ll be in big trouble if your key fob suddenly shuts down.

Proper Replacement

It is important to replace the battery as soon as any of the previous symptoms are notorious. It is also a good idea to always have a spare battery on hand in case of an emergency. You can get a quick and safe replacement with a Mesa mobile auto locksmith.
