What is the reason why the Cadillac XT5 door cannot be locked after rain?

[JesseLee]

Cadillac XTS door cannot be locked due to a problem with the lock block. First, check whether the lock actuator is functioning. It is usually caused by rust, or it could be that the position of the door lock motor latch has shifted. Below are the specific reasons and solutions: Reasons why the door cannot be locked: If you are using the remote key to lock the door, it is very likely that the remote lock is malfunctioning or the antenna of the car's remote transmitter has aged, causing the remote key to not work. In this case, you can use the spare mechanical key to lock the door. Magnetic signal interference: Another situation is that there is strong magnetic signal interference around the car. Since the smart key uses low-intensity radio waves, it cannot function properly under magnetic interference. Door jammer: If the car frequently fails to lock remotely in a certain location, the owner should be wary of a door jammer. Some criminals use a radio signal jammer that can emit electromagnetic waves at the same frequency as the car's locking signal, thereby blocking the electronic password of the car's central lock and temporarily disabling it.
