Any idea where this part is located in the car? I'd like to take it apart and look at it... Since the one I have is apparently broken anyway.
I don't understand why, when following the directions online to reprogram a remote (to lock/unlock doors) I can initiate the sequence and go all through the steps but at the end it will lock twice, in stead of once, which means programming failed. It obviously recognizes the old key, it will even do that with the new key. But, when trying to program the new key for the ignition it will not work, says "Key is Different" every time I put it in.

I'm having the same problem too. I just bought my 2005 UL and I'm having issues with the smart key. I checked the button under the dash and it's depressed. I have 3 keys total and they all don't work. I have to have the key in the ignition to start. Plus the doors and trunk don't open with the exterior buttons. Where can I find the reset procedures for this car?

So did anyone ever figure out what the problem was? I have a 2004 LS430 and my fobs work to unlock/lock and open the trunk, but none of the exterior door lock unlock buttons work. When I try to start the car it sometimes will not allow me to put the smartkey in the ignition and I have to mess with it for a while in order to get the key in and get it to start. Any information would be greatly appreciated.

I bought the new computer module and keys but haven't had it put in/programed yet. I had intended on doing it several months ago but I had a fender-bender and quit driving the car. I need to get the bumper replaced and painted and then drop it off at the dealer and see if they can fix the keys. I've spent a lot of money on it already and now it's just sitting in the garage.
Anyone else bought the part and had it successfully replaced and programed?

UPDATE:
Just got the car back from the Toyota dealership today. They had it for 3 days total (mainly waiting on a new fuse/relay the blew while working on it). They installed the new computer and both keys (the old/original one and the new one bought directly from Lexus). Everything functions as it should with the exception of the keyless ignition. The buttons on the doors and trunk work and the lock/unlock on the keys work. You can enter the car without taking the key out of your pocket, but the car will not start without the key in the ignition. I don't get any message when attempting to start it without the key, the steering wheel comes down when I push in to turn the fob but nothing else happens. Put either key in and it starts just fine. At this point I'm just glad to have they keyless entry fixed. Inserting the key/fob into the ignition isn't that big of a deal. I'm glad I don't have to pull out the blade/metal key and unlock the door every time now.
