2 Answers
Chery Fengyun 2 key uses a CR2032 button battery. Types of battery models: The commonly used ones are basically 2032, 2016, 2025, 1620, 1632, etc. 27A and 23A are not button batteries. Among these, those starting with 2 are the most commonly used, especially 2032. Most car keys are equipped with CR2032 button batteries. Function of car remote keys: Car remote keys mainly include the transmitter inside the key and the receiver installed in the car. Within the signal coverage range of the remote key, pressing the button causes the transmitter to send a signal in the 40MHZ frequency band. After receiving this signal, the receiver will mediate. When the signals match, the receiver will power the door lock relay to complete the unlocking action.
A while ago, my Chery Fengyun 2 car key suddenly stopped working. Upon opening it, I found the battery had aged—it was a CR2032, the common button cell type that’s universal in many car keys. I easily replaced it myself by gently prying open the key casing with a small tool, and the whole process took just minutes. It’s advisable to regularly check the battery lifespan; typically, it should be inspected every one to two years to avoid the hassle of getting stuck when locking or unlocking the car. These batteries are available in supermarkets for just a few yuan each, so keeping a few at home is convenient. For older cars, pay extra attention to these small components to ensure driving safety.
