Had a problem today while in for 15k service on my '04 LS430. They used my valet key to move the car and then I got in to leave using my SmartAccess and the ignition refused to unlock. It worked fine if I inserted the key to start but nothing if it was just in my pocket or held next to the dash. Even the lock/unlock feature was dead; the under dash button was in the right setting. Dealer had to get a tech to "reset the system" to get it functioning and said there was a TSB out there about this and next time it happens they will order the part to fix the problem.

I've done the search on the NHTSA board and find nothing. Anyone have info about this problem?
