When your car key runs out of battery, you can either replace it yourself or go to a 4S shop for battery replacement. Below is an introduction to the specific replacement method: 1. First, use a screwdriver to locate the gap on the side of the key. 2. Then, use the screwdriver to open the car key from the gap and remove the old battery. 3. Next, replace it with a new battery. 4. Finally, reassemble the key. Below is an introduction to car keys: 1. A car key refers to the tool used to switch the car on and off. Nowadays, car keys all use chips, which are part of the magnetic chip system. 2. A remote key allows you to open and lock the door from a distance without inserting the key into the lock. It emits a weak radio wave from the owner, which is received by the car's antenna. The electronic control unit (ECU) identifies the signal code, and then the system's actuator (motor or electromagnetic coil) performs the action of unlocking or locking. This system mainly consists of two parts: the transmitter and the receiver.
