Does the Dongfeng Fengxing Jingyi X5 car key have hidden functions?

[ElizabethRose]

Jingyi X5 remote key does have hidden functions. Concept of car key: A key refers to a tool for unlocking. A car key refers to a tool for switching cars on and off. Modern car keys all use chips, which are part of a magnetic chip system. The reading coil in the car's ignition lock cylinder reads the chip in the key; each chip contains fixed digital information. Advantages of remote keys: Remote keys allow doors to be unlocked and locked from a distance without inserting the key into the lock. The biggest advantage is that regardless of day or night, without needing to locate the keyhole, unlocking and locking can be done remotely and conveniently. The key emits a weak radio wave from the owner's vicinity, 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 lock/unlock action. This system mainly consists of two parts: the transmitter and the receiver.
