Why is there no response after replacing the car key battery?

[MalachiRose]

The reason for no response after replacing the car key battery is code failure. The solution is: insert the car key into the keyhole and repeatedly twist it (note not to start the car), repeat this 4-5 times, then press and hold any button on the key to recode and reactivate it. Car key matching method: 1. Open the driver's side window while keeping other windows closed; 2. Insert the remote key, turn to position 2, then immediately return to position "0", repeat this 4 times; 3. Quickly remove the key, press any button (like unlock) for 4-5 seconds until hearing a "click" sound from the car, indicating successful key coding.
