How to Replace the Battery in a Trumpchi GS4 Key?

[DeGiselle]

The specific steps to replace the battery in a Trumpchi GS4 key are as follows: Locate a small switch on the back of the key fob, press it, then grasp the metal part and pull the mechanical key upwards to remove it. After removing the mechanical key, you will notice a small groove in the middle of the key fob. Use the head of the mechanical key to pry open the key fob cover. This will allow you to remove the old battery and replace it with a new one. Finally, reassemble the key. Below is more information about the key: 1. A remote key allows you to unlock and lock the doors from a distance without inserting the key into the lock. Its greatest advantage is that, regardless of whether it is day or night, you can conveniently unlock and lock the car from a distance without needing to locate the lock hole. 2. The key emits a weak radio wave, which is received by the car's antenna. The electronic control unit (ECU) then identifies the signal code, and the system's actuator performs the locking or unlocking action. This system mainly consists of two parts: a transmitter and a receiver.
