Yes I realized that this could be a problem. The dealer here gave me an keychain that held a significant amount of keys, which I think was responsible for the first key breaking. This is why the I took that chain off on the second key... which has still cracked.
I just called the dealer and found that the keys are not under warranty! Its as if Lexus knows that their keys are cheap and will not cover it.
I'm disgusted with this really. I will be taking the car in for the 30K tuneup which will cost me $700 dollars, and I just took the car in a month ago, and there was nothing wrong.
I wonder if the 30k really necessary ??? It seems like highway robbery to charge $700 when they said the car was fine this month, I should reach 30K in about 2 months... any suggestions ?
