What are the reasons for the keyless entry door handle not being sensed?

[VanPenelope]

The reasons for the keyless entry door handle not being sensed are as follows: Key battery dead: If the system cannot sense the key due to a dead battery, the solution is to replace the key's battery or try starting the vehicle by placing the key near the one-touch start area to see if the vehicle's self-check can eliminate the fault. Poor circuit contact: If there is poor contact in the remote control's circuit, you can go to a specialized repair shop or 4S store for inspection and repair. In-car receiver malfunction: You can check the in-car signal receiver to see if the receiving end is malfunctioning. If the control module is faulty, it needs to be replaced.
