What to Do When the Car Key Battery Dies?

[StOlivia]

When the car key battery dies, you need to replace the battery or use the mechanical key to open the car door. The method is: first locate the mechanical part of the key. The mechanical part of this electronic chip-style key is hidden inside the main body of the key. There is a visible latch on the back of the key's main body—just press it, and the mechanical key will come out. When using the key, be careful not to place it near electronic devices like mobile phones or computers, as this can cause electromagnetic interference. The chip is also prone to damage, which increases the likelihood of chip failure. Avoid throwing the car key around; keep it in a fixed place because the circuit board inside the key is relatively fragile. If thrown around for a long time, it can easily break.
