i will post new thread i think and ask for it to be made sticky but basically you need a flip key with two buttons of ebay or anywhere with the mhz rating as your key. most prob 434mhz like mine
try and get one with a blank blade
get that cut to your car at security place or somwhere that casn cut thses keys
to change the imobilisor chip you need to seperate the flip key top and botton
then remove the
badge( took me ages to figure out why i couldnt slipt the top bit!) you will then see a small screw udo this then the key will open up to reveal a little cylindrical chip.
you then need to open up your spare key the one with no remote this is easy did it with my nails and in that you will see a bit of white rubber and under this in the chip plase this in your flip key and put flip key one in hear fro now!
then reassemble the key and get seat
badge from dealer
to code the remote you need the old original key in the ignition with it turn on then lock the door with the new key remove key then press unlock and horn will blip wait 6 second and press unlock again the key is now coded to your car!
cost about 30 quid including new
badge and plenty on ebay
the key part no. i got and that i know works is HLO 1JO 959 753 AG
