How Long Does the Original Battery of a Car Key Last?

[VanElliot]

Under normal circumstances, the original battery of a car key can last for about 3 years. If the battery of the car remote key runs out of power, it needs to be replaced. Almost all cars come with remote keys, which include a remote control for locking or unlocking the car and even opening the trunk lid remotely. To extend the battery life of the remote key, it is recommended to avoid long-distance remote operations, as this can increase power consumption. Additionally, avoid repeatedly pressing the remote buttons, as this also drains the battery. If the key runs out of power, you can use the mechanical key to unlock the car door. For cars equipped with a push-to-start system, there is a key detection area inside the car where placing the key allows the engine to start normally.
