Sounds like it. My grey key has buttons for the doors but not the boot, but mine is a post-2001 SE-spec car so maybe the valet key is different to earlier or S-spec cars?
DensLex - you said in your first post that you had 3 keys, but that only one works. Do the other two not even fit the locks? Do they have buttons on, which don't work? Does the pattern on the shank look like the same as on the grey key which does work?
They could be completely the wrong keys if the pattern is different - in which case go back to your dealer (assuming this is a recent purchase that is). They may have the correct keys sitting in the key cupboard somewhere. But if not, I'm sorry to say, things might get very expensive as without a working master key you can't cut/program others to suit your locks and ignition.

The other keys I have dont even fit the car.... Im now starting to think that I have been stitched up.......
Ive just spoken to my very friendly and helpful local Lexus garage... they have advised that cos I havent got a master key they cant supply me with any additional keys and I cant get anymore cut..... Im feeling even more upset now ........
Does anymore know if I buy a fob from somewhere like ebay can I re-program ???? Im worried about doing it because my 1st introduction to the World of Lexus isnt going to good at the moment.
To crown it all as well someone smashed my door mirror this morning on the way to work, luckly the case is all Ok but Ive been told that the glass will cost £65.40 plus VAT
