How Long Can a Car Key Be Used After the Low Battery Warning?

[EllaLee]

After the low battery warning, a car key can typically be used for about 3 more hours. The method to replace the car key battery is as follows: 1. Press the circular button on the side of the key to remove the mechanical key; 2. Insert a tool into the gap at the top of the key and pry open the back cover; 3. Push the battery to one side to remove and replace it. The car key utilizes the wireless remote control function of the central locking system, allowing doors to be unlocked and locked from a distance without inserting the key into the lock. If the key runs out of battery, the starting method is: 1. Press the button on the side of the remote key to remove the mechanical key; 2. Insert the key into the door handle of the driver's side and open the door; 3. Place the car key near the lower right corner of the steering wheel and press the start button.
