With 2 other people on a forum they had the same problem, I told them to take a cloth on a rag and clean the lens at the bottom of the keyhole. Its possible that something was stuck on the key and this went onto the pickup lens.
Neither of them came back with an answer so I do not know.
I re read the WIS info,,, the coding is done before you start and you take the info out of the car, nothing to do with keys being programmed on the STAR bit I have read it all
