What Are the Reasons for No Response When Pressing the Car One-Button Start Switch?

[MacHector]

Reasons for no response when pressing the car one-button start switch: When the vehicle's smart key runs out of battery, the key's transmission power becomes very low, making it difficult for the car's sensor to detect it, which renders the one-button start function unusable. If the one-button start function malfunctions, the only way to start the car is by using the key. Keys with keyless entry function often have a folding or hidden mechanical key inside. Simply unfold the folding key to find the keyhole and open the door. If the key is hidden, the mechanical key is usually stored inside the main key and can be pulled out when needed to unlock the door.
