Hi all,
There's so much info all over the net but hard to piece it all together. I too have a 2007 IS250 with only one fob/key and need a backup fob.
I've got a stack of questions that I'd love answered only if you're 100% certain of the answer...
In this thread there's talk of frequencies changing due to replacing of parts under warranty. What was the old and which is the new frequency? Is the only difference between the fobs the crystal and if so can't it be replaced? I have a remote with has the word HOLD on it, is this new or old? My crystal reads 31435, is this a 315Mhz transmitter/fob/SmartAccess? Given the above info what part number would I require? There's also talk of users using an OBDII tool to perform the programming themselves. Has anyone actually done this? Apparently the pairing between fob and car writes info to the fob, has anyone worked out how to clear this data to make old fobs new/blank again?
Basically there seems to be a lot of talk but nobody is coming forward with their good or bad news stories. I'd love to hear both sides so I can decide which path I take - Lexu$ or DIwhy did I
Thanks in advance
