Hey gang! Being reading lots of good advice here and am posting for the first time today regarding an issue I can't seem to find an answer to anywhere.

When I first got my 2006 Lexus RX400h (LOVE the car, btw), I would unlock all the doors by clicking twice on the unlock button on the key fob, then hold it down to open the trunk.

My dad went to get something from the trunk and I gave him the same instructions. Well when he did it (we were in the middle of a rain storm) all of the windows opened and not the trunk. Now this is what happens every time.

I'm not sure what happened, but I'm really missing opening my trunk through my key fob especially when my hands are full. Does anyone have any advice on why this is happening and how I can open my trunk using the key fob again?

 

That sounds like normal operation. Not sure why it would have changed for you. See pages 36 & 37 from the 2006 RX 400h manual:

Yup, hold down the unlock button and the windows & sunroof open. The power rear door is a separate button on the remote.

 

Thanks you guys! I had a bit of an air-head moment. To help clarify for others who might run into this, here's what I learned...

The Unlock button when held down (when all doors are unlocked) opens all the windows.

The button to the right of it that's used to set the car's alarm and lock the doors, when held down (when all the doors are unlocked) opens AND closes the trunk.

 

Which remote do you have? It sounds like you should have the one on the left on page 32 in the link above. However, the button to the right of the unlock button doesn't lock the doors on either of those remotes.

 

None of your descriptions sound like the OEM remote. It sounds like you have an aftermarket alarm. The OEM remote is built into the key and has three buttons. Lock, Unlock, and PWR Door. The lock button will lock the car and will turn on the panic alarm when it is held down. The unlock button will unlock the car and will roll the windows down if it is held down. The PWR Door button controls the back door only and can be configured by the dealership to operate in several methods. If your remote doesn't have these specific three buttons, then you do not have a factory remote and the forum will be no help to you.
