How Long Does a Car Remote Key Battery Typically Last?

[LaSienna]

Car remote key batteries typically last between 4 to 6 years. When the remote key runs out of power, you can first use the mechanical key to unlock the vehicle and then promptly replace the remote key battery. Below are some precautions for using car remote keys: Prevent Magnetic Interference: Do not place the car key near electronic devices that emit radiation, as smart keys use low-intensity radio waves and are highly susceptible to magnetic interference. Avoid Heavy Impact: Do not throw the car key or subject it to mechanical shocks. The chip inside the smart key is fragile, and any impact may damage the key, rendering it unusable. Prevent Water Damage: Smart keys must not get wet, as this can easily cause short circuits and damage. If the key gets wet, lay it flat immediately and dry it with a hairdryer.
