Just recently one of my car keys has stopped turning off the immobiliser on my 2019 Plus 4 GDI.
Starting procedure is "touch end of key to the ignition key block" (I mean the plastic end of the key where the RFID chip is)
Immobiliser light goes out - insert key - start engine.
Did this several times the other day - and immobiliser light didn't go out - therefore non starting car
Got my spare ignition key - procedure as above - immobiliser light goes out - car starts no problem
From reading the forum and my simple understanding, the RFID chip in the key is "inert" - There is no battery in the key (basically like the security tags on whisky bottles / clothes etc in shops).
So in "theory" - nothing can go wrong with the chip?
Thoughts?
