When I got my felly, it had a metal tag with letters/numbers stamped on it attached. Is this the immobiliser code ?Tag is about 3/4 " long, 1/2 " wide ( that's 19mm x 12mm)

i though they had a plastic tag with the immo code tbh, but it sounds like it must be the code.... dont worry though, you will probably never need it

yes, i got one too.. but my metal tag has a white sticker with the info on it :p

The SKC will be a 4-digit number, although later cars post-2002 (i.e. probably not a Felicia) have 7-digit ones instead. I'm not sure about the tag either but like Tom I was under the impression that the SKC tag was plastic with the code under a scratch-off panel. If it's 14 alphanumeric characters it might be the immobiliser ID, which isn't particularly useful for anything on its own (and is written on the side of the unit anyway, I think)
