Hi, Update. I got this sorted with some advice from a friend of mine who used to be a technician at Lexus. I thought he might have the techstream software, but first he advised me to disconnect the battery for half an hour to let the ECUs and control boxes reset themselves. I did this whilst installing our UK radio headunit. After this the original remote started working fine and has been now for about a month. So a nice easy fix in the end! This has sorted all types of electrical gremlins at Lexus apparently. Hope this helps someone. Cheers, Russ.

No problem Picasso, thanks for coming back to me. Excuse my ignorance, but how do I get the techstream software? Cheers Russ.

I think mine is a Gen 1. Its a 3.0 with a 4 speed box which I think ,makes it pre-facelift. Cheers Russ.

Thanks for your answers. I will look into it. Cheers Russ.

Hi Picasso, reg No is 540 RKK. Its the one that came with vehicle and was working fine for many years. Cheers Russ.

Hi, I have had my 2005 Alphard since 2016 and the side door remote has always worked ok until recently when it stopped working. Changed the battery, no difference. So I bought a replacement from eBay but I am having trouble programming it to the car. I have attached the instructions that I have been using (supplied by the seller) and a picture of the remote. Everything is ok to step 9, car goes into programming but then the instructions do not match the remote, saying press lock and unlock together for 1 second, then press lock, doors will cycle. In my case I have tried variations of the buttons but no joy. The remote seller has said that it should work and has now sent me 3 remotes but still no luck. I have the following questions please, Is there a different programming method for my remote? Does anyone have a different remote for my year of car that works and I should try to find? Many thanks for any help. Cheers Russ. Key programming instructions.docx

I like the sound of this. Would go for the convoy, will raise a few eyebrows I think! The show and shine wouldn't be for me. Our Alphard is used for everything but I will throw a bucket of water over her before hand. Might go for the camping. Will give me a chance to use the curtains that I've been carrying around since we bought this one in 2016.
