Be very careful, even if buying a spare key from Land Rover, Keys 1 & 2 are different, AND they are a different colour, but only slightly, one is 'brown' the other is slightly black,its VERY easy to buy the wrong one, & it WILL NOT work, if you already have a 'No.1', then you must buy a 'No.2' & vice-versa.
Its only when the 2 keys are side-by-side that you can see the difference.
They have a sticker on the back with the number, but mine is missing & I need to see someone else's to see the difference ( I think I have a No. 1)
There is NO WAY any other key bought on e-bay (or any where else) will work, it HAS to come from Land-Rover & they need your cars details ( to program it) & what No. key you already have.
