When the car key battery is running low, the dashboard inside the car will display a low battery warning, prompting you to replace the battery promptly. Here are some ways to determine if your car key battery is dying: 1. Time-based judgment: The lifespan of the car key battery depends on usage frequency. Under normal circumstances, the coin battery in the car remote key can last 2-3 years. You may choose to replace the battery within this timeframe. 2. Reduced remote range: Normally, the car key can unlock the car from a distance of 5-6 meters. If this range gradually decreases, it indicates the battery is losing power. When you can only unlock the car by standing right next to the door, it means the car key battery is almost dead. 3. Dashboard display: As mentioned earlier, when the car key battery is running low, the dashboard will show a low battery warning, reminding you to replace the battery in time.
