ST170 2002 .
Long story but I need to fit a new column. As the barrel/transponder is stuck behind the Kiltech can I change the whole thing and just plug it in and it will work, or will I need to reprogram everything to work with the new transponder and key ? There's one for sale on ebay with everything including the ECU,

but it only comes with one key and I heard you need two to make it work ?

Help.
