I just bought a new LS 460 2011 to replace my 2008. Yesterday, during delivery, the car intermittently cannot detect the key. The tech thought it was the battery for the key, changed the bats, no key detected keeps on flashing. Car would start after several tries. It was getting late, so I thought I will just bring it back the following day (today). But as I was pulling out of the delivery bay, the car start beeping and the "key not detected" message flashed, while the engine was on. The dellivery lady eventually suggested to leave the car for safety.

Today, I got a call from my salesperson. The problem was due to the new frequency being used in the post Tsunami vehicles, from FM to AM. Our RX 350 keys (FM) were in my pocket and my wife's purse. Apparently, the AM (LS 460 2011) and the FM frequencies were interfering with each other causing the intermittent problems recognizing the key.

Is this for real? I will be picking the car up later tonight. This would be a big hassle. I am sure there are a lot of Lexus owners with multiple lexuses who have multiple keys in their pockets and purses. Are we supposed to separate all our keys?

Anybody else experiencing the same problem?

I am skpetical about the explanation. If true, Lexus should fix this. ASAP

Any feedback?
