1 Answers
Method for replacing the battery in a Trumpchi GS3 key: Press the button arrow to eject the mechanical key, use a small flat-head screwdriver to pry open the casing, and then install the new battery. Below is a related introduction: Remote keys can be categorized into three types based on their usage methods: active working mode, passive working mode, and coil induction mode: 1. Active working mode operates by using the vehicle's electronic module and body control module to control the doors. Simply press the key button to send an unlock/lock command, which, after verification by the vehicle's electronic module, will open/close the doors. 2. Coil induction mode primarily involves placing an encrypted chip inside the key. During the unlocking process, the vehicle's RF transceiver verifies whether the key matches to determine if the engine can be started. This is mainly used in special cases where the key has no power, allowing the car to still start normally. 3. Passive working mode occurs when the owner enters the sensing range of the key system. Upon touching the door handle, the identity-recognition key carried by the owner will receive a low-frequency signal sent by the car. If this signal matches the identity-recognition information stored in the key, the key will be activated.
