What is the reason for the car key not responding after replacing the battery?

[LeVivienne]

Car key not responding after replacing the battery is caused by coding failure. You can insert the car key into the keyhole and repeatedly turn it, being careful not to start the car. After repeating this four or five times, press and hold any button on the car key to recode and activate it. This smart key can emit infrared signals, which can open one or two car doors, the trunk, and the fuel filler cap, and can also operate the car's windows and sunroof. Things to note about car keys: 1. Do not keep the key with mobile phones or bank cards for a long time, as it can cause electronic interference; 2. Try to keep it in a dry place and avoid soaking it in water, otherwise electronic malfunctions may occur.
