Having got home and adjusted the key with a file so that it actually turned in the ingnition there is a problem.
The transponder module is situated too far away from the ignition switch to disable the immobiliser. If you hold the original key alongside the flip key housing the module is approx 1" further away than it would be with the original key.
I hope that those chinese who are making the ones for XCGUARD have taken this into account and made the transponder module nearer the acual key - if that is atall possible.
Apologies to anyone who has gone to ebay for one - I shall be contacting seller to explain that for UK Honda Civics this item is useless.
