    Yes the battery in the fob is good and the fob is putting out a strong signal. It was checked at a security and Lock smith shop this morning.

    The receiver in the body control module and the signal to the actuators at the doors and trunk need verification .

    If you can get to the actuator in the trunk and disconnect or back probe the connector to see if you have a signal to that point would be easier than pulling a door panel .

The outer cone is where the problem is, right where the fiber/foam of the cone material attaches to the outside metal frame. if you look closely, you will find the speaker is torn along this line, at least at some point(s). I used ge silicone 2 clear, make a bead all the way around, took about ten minutes, could not be better. Great fix. Also check lexus owners club for more detail.

You probably have a dead battery or a lead from the battery came undone.

I'd suggest taking the battery out and taking it to your local automotive stores and having them test it. If you have another car you can spare, i'd pull the battery from that one and throw it your lexus to verify.

But from the sounds of it, it sounds like you're just dealing with a dead battery.

Good luck!

Car won't start after using Auto headlights on 2005 Lexus LS430


The trunk should auto close when you manually lower the lid to the almost closed position, but it is NOT designed to open up fully when you hit the trunk release on the key fob, nor when you open the trunk manually using the touch sensitive button under the lip of the trunk.
