hi, I am looking to get my card key replaced, got 2 normal keys. Lexus quoted $971... ouch. Looking for alternative option, I have techstream and looking to just buy a new card key to program myself. but do not know what the card key frequency is or type as I understand US version are not compatible. can someone shed some light on this so I know what to buy as in, can current 2014-2016 IS350 owners take a photo of back of card key showing FCC ID so I know what to buy. many thanks in advance.
