Yesterday I overheard a conversation where someone was telling his pal how
he had stolen a Sonata.
He had found some keys in a car park with the locking remote fob and found
the car they belonged to simply by walking around the car park pressing the
remote unlock. The turn lights flashed and, hey presto, he stole the car!
My question is this:
Is it possible to disable the turn lights from flashing when using the
remote unlock function?
