i always though you could only get this via vauxhall with id and the log book. i took my dads new car 1.0 corsa 02 plate he only had 1 key went to timpsons for a key cutting as a spare just so he can keep in his wallet to at least get in his car if he lost the other they were able to code it in via the ecu and get the security code from the ecu and did it there and then ??? also with opcom ive heard you can do the same with it connected unplug the imob unit reconnect it and read and it will read the security code.
