I posted a how to programme remote the other day.
Ign Pos 1 ( radio on ) turn to pos 2 ( ign lights on ) and back to pos 1 four times within 6 secs, chime will be heard on cars built upto 2005 ( I think! ) turn to pos 0, press and hold a button on fob for a few secs, chime will be heard ( see note above! ), press and hold button on additional Fob to be programmed ( upto 8 can be programmed, again memory!

)within 6 secs.
Voila, programmed remote Fob!
N.B, not to be confused with the immobiliser!
Agree with the above, with regards to bonnett and disconnecting battery to avoid upsetting neighbours, just wish I could disconnect our neighbours dogs` batteries at 11:30PM and 6:00AM, sods!
