How Often Should the Battery in a Smart Car Key Be Replaced?

[DeHarmony]

Generally, a new car key can last for two to three years when fully charged. Signs that the car key battery is running low: Reduced effective range: Previously, the car door could be unlocked within a distance of 6 meters, but when the key battery is low, you need to get closer to the car, even right next to the door, for it to respond. This indicates that the car key battery is almost depleted. Occasional remote failure: When using the remote to unlock the car door, it sometimes works and sometimes doesn't. You might need to press the button multiple times for a response, which means the car key battery is nearly dead. Dim indicator light: Observe the indicator light on the key. When you press the button, the light may appear dimmer than usual or flicker intermittently. This is a sign that the battery needs to be replaced.
