Why does the trunk of a Lexus RX 350 open randomly by itself even when the car is locked?

Answer 1

The trunk of a Lexus RX 350 may open randomly by itself when the car is locked due to a malfunction in the electronic trunk release system. This can be caused by issues such as a faulty trunk release button, a malfunctioning key fob, or a wiring problem in the vehicle's electrical system. It is recommended to have the car inspected by a certified mechanic to diagnose and repair the issue.

Answer 2

Well, honey, that trunk ain't opening itself just for kicks. It could be a glitch in the keyless entry system causing it to pop open unexpectedly. Might wanna get that checked out by a professional before your groceries start making a run for it.

Answer 3

The button on the remote control may getting pressed inadvertently by keys or other objects in your purse or pocket. This may be relevant if the opening of the trunk happens when the remote control is within 100 ft (30 m) of the vehicle, i.e., within radio range. (The distance may vary, depending on nearby obstructions and interfering electrical signals.)

To eliminate the remote control as the source of the problem, store it in a manner that prevents the buttons from being pressed accidentally and see if the trunk still opens randomly on its own. One could also completely wrap the remote control in aluminum foil during the test period, to prevent radio emissions if the control is malfunctioning and sporadically transmitting even if a button isn't pressed. Removing the batteries from the remote control is not a good idea, as most modern electronic lock systems use a "rolling code" security scheme, and removing power from the remote can cause it to lose synchronization with the receiver in the car and would require re-training the system after the batteries are reinstalled.
