How Long Does a Car Remote Key Battery Typically Last?

[VanEverett]

A new car key with a fully charged battery can typically last two to three years. The lifespan of the key may vary depending on the frequency of use and the specific car model. Below are specific signs indicating that a car key battery is running low: 1. Reduced effective range of the car key remote: Previously, the car door could be unlocked within a range of 6 meters, but when the battery is low, you may need to get closer to the car, sometimes even right next to it, for it to respond. This indicates that the key battery is nearly depleted. 2. Unresponsive remote key: If the key works intermittently or requires multiple presses to respond, it suggests the battery is running low. 3. Dim indicator light: If the indicator light on the car key is noticeably dimmer than usual or flickers, it means the battery is almost dead and needs to be replaced promptly.
