Mine's not working either. At the dealer ship we reprogrammed it to open all doors. I took off and when I got home it wasn't working. I need to unlock the car with the remote...but the car does start. I'll look into the autosensing thing and see if it helps. Kinda weird though.

Still Unsolved ...
Given the holidays, the soon to be 4 week old IS350 will have been in the shop 1 week come tuesday. They THINK it has to do with the 'control center', but are not positive.
If anyone else has had this problem, or has any ideas, please join in,

Hey jdmba I think I know what your problem might be. My car was working fine at the dealership and when I drove it home it stopped working. I hope this works: Make sure you don't have your spare key in the car. If both keys are close by the car it won't work. As soon as I took my spare out of the car, it started working again. Goodluck. There is also a page on the manual that will tell you some reasons of it not working. Found this information from there.

Thanks ... but ...
Thanks for the tip ... I am glad your car is working!
I don't think, if it has been to 2 dealers, and the 2nd dealer (who was also the seller) has had it for a week (tomorrow), that it is such a simple fix.
Hopefully we will get an update tomorrow.

It will be at least another week
Got an update yesterday.
So far, they have replaced the master computer and the key fobs. However, because they didn't also replace the immobilizer, the immobilizer kicked in on seeing the new parts.
They have ordered an immobilizer, but since the car is so new to market, it has to come from Japan. Lexus corporate will be dispatching one of their mechanics to oversee the installation, and integration of the three items.
They predict at least a week before they get the part. At that point, the car will have spent 50% of our ownership of it, in the shop.
Ugh

Got it back
We got the car back from the second repair attempt today. We have owned the car since 12/1/05, and it has spent 19 days in the shop.
Anyway, they wound up having to replace the key fobs, the main computer, and the security sensors. You cannot replace one without all 3 or the car will lock out. You cannot take parts from an existing car to replace any of them because the car will lock out.
Anyway, they got a new computer from Japan last week, and realized they needed a new security sensor (there are 2) which they couldn't cannibalize. They had to order the new sensor (they already had the key fobs), and once they put all three in, with the help of Lexus, the car worked.
At least it worked today. Let's see what happens.
The report showed 18.5 hours of work and $1700 in parts. Of course it was free, but it was almost $3,000 in repairs.

Seems really odd how it worked since the car was made in the factory and in the dealership but not after it's sold.
I'm thinking the probem is the immobilizer. The signals for the keys on the fob are not likely to be encrypted so they should work. The fob probably works fine and the problem is with the RF sensors in the car. Im taking a shot in the dark but the car could have had its immobilizer triggered. How I'm not sure.
